• When using Bundler and Rails 2.3.5 I get uninitialized constant SubdomainFu when migrating

  - by user347480

  Hi I'm using bundler with rails 2.3.5 and I'm trying to make sure everything is working correctly but when I do a "rake db:migrate --trace" I get this ** Invoke db:migrate (first_time) ** Invoke environment (first_time) ** Execute environment rake aborted! uninitialized constant SubdomainFu /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:443:inload_missing_constant' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:80:in const_missing' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:92:inconst_missing' /Users/node/Projects/Race-RX/config/initializers/subdomain_config.rb:1 /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:145:in load_without_new_constant_marking' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:145:inload' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:in new_constants_in' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:145:inload' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:622:in load_application_initializers' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:621:ineach' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:621:in load_application_initializers' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:176:inprocess' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:in send' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/initializer.rb:113:inrun' /Users/node/Projects/Race-RX/config/environment.rb:9 /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in gem_original_require' /opt/local/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:inrequire' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in require' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:521:innew_constants_in' /opt/local/lib/ruby/gems/1.8/gems/activesupport-2.3.5/lib/active_support/dependencies.rb:156:in require' /opt/local/lib/ruby/gems/1.8/gems/rails-2.3.5/lib/tasks/misc.rake:4 /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:incall' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:636:in execute' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:ineach' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:631:in execute' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:597:ininvoke_with_call_chain' /opt/local/lib/ruby/1.8/monitor.rb:242:in synchronize' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:ininvoke_with_call_chain' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:607:in invoke_prerequisites' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:ineach' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:604:in invoke_prerequisites' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:596:ininvoke_with_call_chain' /opt/local/lib/ruby/1.8/monitor.rb:242:in synchronize' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:590:ininvoke_with_call_chain' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:583:in invoke' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2051:ininvoke_task' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:ineach' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2029:in top_level' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:instandard_exception_handling' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2023:in top_level' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2001:inrun' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:2068:in standard_exception_handling' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/lib/rake.rb:1998:inrun' /opt/local/lib/ruby/gems/1.8/gems/rake-0.8.7/bin/rake:31 /opt/local/bin/rake:19:in load' /opt/local/bin/rake:19 I don't know what could be causing this. I did however but my require "rubygems" require "bundler" Bundler.setup in my enviroment.rb file but that doesn't see to be the problem.

• Installed Perl DBI Module Can't Be Found

  - by Russell C.

  I'm trying to setup a Perl development environment on my Mac laptop and have been having a really hard time getting it working. I thought I had everything configured correctly but when I try to run a sample script it is reporting errors with the DBI module and can't access the DB. Here is what is reported in the Apache error logs: [Fri Apr 30 23:11:33 2010] [error] [client 127.0.0.1] Can't locate DBI.pm in @INC (@INC contains: /Library/Perl/Updates/5.10.0/darwin-thread-multi-2level /Library/Perl/Updates/5.10.0 /System/Library/Perl/5.10.0/darwin-thread-multi-2level /System/Library/Perl/5.10.0 /Library/Perl/5.10.0/darwin-thread-multi-2level /Library/Perl/5.10.0 /Network/Library/Perl/5.10.0/darwin-thread-multi-2level /Network/Library/Perl/5.10.0 /Network/Library/Perl /System/Library/Perl/Extras/5.10.0/darwin-thread-multi-2level /System/Library/Perl/Extras/5.10.0 .) at main.pm line 5.

I honestly don't know what option makes more sense and could use guidance on that as well. As you can probably tell I'm pretty lost at the moment. Please help!!!

• Hudson + Jboss AS 7.1 + Maven 3 Project Build Error

  - by Zehra Gül Çabuk

  I've wanted to prepare an environment that I'm able to build my project and run my tests on a integration server. So I've installed an Jboss application server 7.1 and deployed hudson.war to it. Then I've created a project to trigger "mvn clean install" and when I built it I've got following exception.

So how can I configure the hudson to force it looking at the right place for jars? Is there anyone has an idea? Thanks in advance.

• Ruby Rails Mongrel Sever failing to serve OXS1.6

  - by Mark V

  Hi there I'm fairly new to Rails and the Mac, and doing my first deploy... I'm trying to set up my rails app on a brand new Apple mini-server running OXS1.6 (Snow Leopard). It is currently running fine on my new iMac i7 (same OS). I start mongrel with this command: mongrel_rails start -e production -p 3000 -d -a 127.0.0.1 --debug And it starts giving this output in the log/mongrel.log ** Daemonized, any open files are closed. Look at log/mongrel.pid and log/mongrel.log for info. ** Starting Mongrel listening at 127.0.0.1:3000 ** Installing debugging prefixed filters. Look in log/mongrel_debug for the files. ** Starting Rails with production environment... /Library/Ruby/Gems/1.8/gems/rails-2.3.5/lib/rails/gem_dependency.rb:119:Warning: Gem::Dependency#version_requirements is deprecated and will be removed on or after August 2010.

It might not work well. ** Mongrel 1.1.5 available at 127.0.0.1:3000 ** Writing PID file to log/mongrel.pid The output is the same on my dev iMac (including the warnings). The difference is that accessing http://127.0.0.1:3000 on my iMac serves up the app's login page. Where as on the mac mini-server accessing the same results in this error 500 text from mongrel: "We're sorry, but something went wrong." It's as if rails is not working. I'm pretty good at figuring things out if I have some log file messages to direct me, but mongrel.log has no error message (the output remains the same as above), and the log/production.log is empty (which makes me think rails has not started?). My gems are all the same versions between machines and so is the app code; and there are no clues I can see in any of the mongrel_debug logs, except that rails.log on the mac mini-server and the iMac are different. After a start and single access, first is the rails.log from the mac mini-server: D, [2010-04-15T13:45:34.870406 #6914] DEBUG -- : TRACING ON Thu Apr 15 13:45:34 +1200 2010 Thu Apr 15 13:46:08 +1200 2010 REQUEST / --- !map:Mongrel::HttpParams SERVER_NAME: 127.0.0.1 HTTP_ACCEPT: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 HTTP_CACHE_CONTROL: max-age=0 HTTP_HOST: 127.0.0.1:3000 HTTP_USER_AGENT: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_0; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.9 Safari/533.2 REQUEST_PATH: / SERVER_PROTOCOL: HTTP/1.1 HTTP_ACCEPT_LANGUAGE: en-US,en;q=0.8 REMOTE_ADDR: 127.0.0.1 PATH_INFO: / SERVER_SOFTWARE: Mongrel 1.1.5 SCRIPT_NAME: / HTTP_VERSION: HTTP/1.1 REQUEST_URI: / SERVER_PORT: "3000" HTTP_ACCEPT_CHARSET: ISO-8859-1,utf-8;q=0.7,*;q=0.3 REQUEST_METHOD: GET GATEWAY_INTERFACE: CGI/1.2 HTTP_ACCEPT_ENCODING: gzip,deflate,sdch HTTP_CONNECTION: keep-alive While on my iMac it seems the same except for the addition of the HTTP_COOKIE and the HTTP_IF_NONE_MATCH, here is rails.log from my iMac # Logfile created on Thu Apr 15 13:41:42 +1200 2010 by logger.rb/22285 D, [2010-04-15T13:41:42.934088 #2070] DEBUG -- : TRACING ON Thu Apr 15 13:41:42 +1200 2010 Thu Apr 15 13:42:05 +1200 2010 REQUEST / --- !map:Mongrel::HttpParams SERVER_NAME: 127.0.0.1 HTTP_ACCEPT: application/xml,application/xhtml+xml,text/html;q=0.9,text/plain;q=0.8,image/png,*/*;q=0.5 HTTP_HOST: 127.0.0.1:3000 HTTP_USER_AGENT: Mozilla/5.0 (Macintosh; U; Intel Mac OS X 10_6_3; en-US) AppleWebKit/533.2 (KHTML, like Gecko) Chrome/5.0.342.9 Safari/533.2 REQUEST_PATH: / SERVER_PROTOCOL: HTTP/1.1 HTTP_IF_NONE_MATCH: "\"216cc63ce3c1f286ef8dd4f18f354f6e\"" HTTP_ACCEPT_LANGUAGE: en-US,en;q=0.8 REMOTE_ADDR: 127.0.0.1 PATH_INFO: / SERVER_SOFTWARE: Mongrel 1.1.5 SCRIPT_NAME: / HTTP_COOKIE: _ServiceApp_session=BAh7DDonY3VzdG9tZXJfbGlzdF9maWx0ZXJfam9iX3N0YXR1c19pZGn6Og9zZXNzaW9uX2lkIiU0ZTk1ZWZjMmViMGU3NjE2YzA0NDc2YTkxYzJlNDZiOToaY3VycmVudF9jdXN0b21lcl9uYW1lIilUSEUgQ1VTVE9NRVIgTkFNRSBORUVEUyBUTyBCRSBMT0FERUQ6EF9jc3JmX3Rva2VuIjFuT1JMUWk0NlZrWlM3c2lUN3BaWCs5NkhRajhxYnFwRnhzVHVTWXEvUWY0PToZam9iX2xpc3RfZmlsdGVyX3RleHQiADogam9iX2xpc3RfZmlsdGVyX2VtcGxveWVlX2lkafo6HmN1c3RvbWVyX2xpc3RfZmlsdGVyX3RleHQiAA%3D%3D--d01bc5d0b457ad524d16cb3402b5dfed9afce83d HTTP_VERSION: HTTP/1.1 REQUEST_URI: / SERVER_PORT: "3000" HTTP_ACCEPT_CHARSET: ISO-8859-1,utf-8;q=0.7,*;q=0.3 REQUEST_METHOD: GET GATEWAY_INTERFACE: CGI/1.2 HTTP_ACCEPT_ENCODING: gzip,deflate,sdch HTTP_CONNECTION: keep-alive Any direction or ideas would be greatly appreciated.

• Error when pushing to Heroku - StatementInvalid - Ruby on Rails

  - by bgadoci

  I am trying to deploy my first rails app to Heroku and seem to be having a problem. After git push heroku master I get an error saying that relation "tags does not exist. I understand that without knowledge of my application it will be hard to help but I am wondering if someone can point me in the right direction. I have checked the schema.rb file and also been over all my migrations and there doesn't seem to be a problem there. The error message lead me to believe that I left something out of my routes.rb file but can't seem to find anything there either. Perhaps just some help deciphering this message.

• Cannot connect to MySQL with JDBC - Connection Timeout - Ubuntu 9.04

  - by gav

  I am running Ubuntu and am ultimately trying to connect Tomcat to my MySQL database using JDBC. It has worked previously but after a reboot the instance now fails to connect. Both Tomcat 6 and MySQL 5.0.75 are on the same machine Connection string: jdbc:mysql:///localhost:3306 I can connect to MySQL on the command line using the mysql command The my.cnf file is pretty standard (Available on request) has bind address: 127.0.0.1 I cannot Telnet to the MySQL port despite netstat saying MySQL is listening I have one IpTables rule to forward 80 - 8080 and no firewall I'm aware of. I'm pretty new to this and I'm not sure what else to test. I don't know whether I should be looking in etc/interfaces and if I did what to look for. It's weird because it used to work but after a reboot it's down so I must have changed something.... :). I realise a timeout indicates the server is not responding and I assume it's because the request isn't actually getting through. I installed MySQL via apt-get and Tomcat manually.

• How do I convert Data::Dumper output back into a Perl data structure?

  - by newbee_me

  Hi all! I was wondering if you could shed some lights regarding the code I've been doing for a couple of days. I've been trying to convert a Perl-parsed hash back to XML using the XMLout() and XMLin() method and it has been quite successful with this format. #!/usr/bin/perl -w use strict; # use module use IO::File; use XML::Simple; use XML::Dumper; use Data::Dumper; my $dump = new XML::Dumper; my ( $data, $VAR1 ); Topology:$VAR1 = { 'device' => { 'FOC1047Z2SZ' => { 'ChassisID' => '2009-09', 'Error' => undef, 'Group' => { 'ID' => 'A1', 'Type' => 'Base' }, 'Model' => 'CATALYST', 'Name' => 'CISCO-SW1', 'Neighbor' => {}, 'ProbedIP' => 'TEST', 'isDerived' => 0 } }, 'issues' => [ 'TEST' ] }; # create object my $xml = new XML::Simple (NoAttr=>1, RootName=>'data', SuppressEmpty => 'true'); # convert Perl array ref into XML document $data = $xml->XMLout($VAR1); #reads an XML file my $X_out = $xml->XMLin($data); # access XML data print Dumper($data); print "STATUS: $X_out->{issues}\n"; print "CHASSIS ID: $X_out->{device}{ChassisID}\n"; print "GROUP ID: $X_out->{device}{Group}{ID}\n"; print "DEVICE NAME: $X_out->{device}{Name}\n"; print "DEVICE NAME: $X_out->{device}{name}\n"; print "ERROR: $X_out->{device}{error}\n"; I can access all the element in the XML with no problem. But when I try to create a file that will house the parsed hash, problem arises because I can't seem to access all the XML elements. I guess, I wasn't able to unparse the file with the following code. #!/usr/bin/perl -w use strict; #!/usr/bin/perl # use module use IO::File; use XML::Simple; use XML::Dumper; use Data::Dumper; my $dump = new XML::Dumper; my ( $data, $VAR1, $line_Holder ); #this is the file that contains the parsed hash my $saveOut = "C:/parsed_hash.txt"; my $result_Holder = IO::File->new($saveOut, 'r'); while ($line_Holder = $result_Holder->getline){ print $line_Holder; } # create object my $xml = new XML::Simple (NoAttr=>1, RootName=>'data', SuppressEmpty => 'true'); # convert Perl array ref into XML document $data = $xml->XMLout($line_Holder); #reads an XML file my $X_out = $xml->XMLin($data); # access XML data print Dumper($data); print "STATUS: $X_out->{issues}\n"; print "CHASSIS ID: $X_out->{device}{ChassisID}\n"; print "GROUP ID: $X_out->{device}{Group}{ID}\n"; print "DEVICE NAME: $X_out->{device}{Name}\n"; print "DEVICE NAME: $X_out->{device}{name}\n"; print "ERROR: $X_out->{device}{error}\n"; Do you have any idea how I could access the $VAR1 inside the text file?

• Ant + JUnit: NoClassDefFoundError

  - by K-Boo

  Ok, I'm frustrated! I've hunted around for a good number of hours and am still stumped. Environment: WinXP, Eclipse Galileo 3.5 (straight install - no extra plugins). So, I have a simple JUnit test. It runs fine from it's internal Eclipse JUnit run configuration. This class has no dependencies on anything. To narrow this problem down as much as possible it simply contains: @Test public void testX() { assertEquals("1", new Integer(1).toString()); } No sweat so far. Now I want to take the super advanced step of running this test case from within Ant (the final goal is to integrate with Hudson). So, I create a build.xml: <project name="Test" default="basic"> <property name="default.target.dir" value="${basedir}/target" /> <property name="test.report.dir" value="${default.target.dir}/test-reports" /> <target name="basic"> <mkdir dir="${test.report.dir}" /> <junit fork="true" printSummary="true" showOutput="true"> <formatter type="plain" /> <classpath> <pathelement path="${basedir}/bin "/> </classpath> <batchtest fork="true" todir="${test.report.dir}" > <fileset dir="${basedir}/bin"> <include name="**/*Test.*" /> </fileset> </batchtest> </junit> </target> </project> ${basedir} is the Java project name in the workspace that contains the source, classes and build file. All .java's and the build.xml are in ${basedir}/src. The .class files are in ${basedir}/bin. I have added eclipse-install-dir/plugins/org.junit4_4.5.0.v20090423/junit.jar to the Ant Runtime Classpath via Windows / Preferences / Ant / Runtime / Contributed Entries. ant-junit.jar is in Ant Home Entries. So, what happens when I run this insanely complex target? My report file contains: Testsuite: com.xyz.test.RussianTest Tests run: 1, Failures: 0, Errors: 1, Time elapsed: 0 sec Testcase: initializationError took 0 sec Caused an ERROR org/hamcrest/SelfDescribing java.lang.NoClassDefFoundError: org/hamcrest/SelfDescribing at java.lang.ClassLoader.defineClass1(Native Method) at java.lang.ClassLoader.defineClass(Unknown Source) at java.security.SecureClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.defineClass(Unknown Source) at java.net.URLClassLoader.access$000(Unknown Source) at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) at java.lang.reflect.Constructor.newInstance(Unknown Source) Caused by: java.lang.ClassNotFoundException: org.hamcrest.SelfDescribing at java.net.URLClassLoader$1.run(Unknown Source) at java.security.AccessController.doPrivileged(Native Method) at java.net.URLClassLoader.findClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at sun.misc.Launcher$AppClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClass(Unknown Source) at java.lang.ClassLoader.loadClassInternal(Unknown Source) What is this org.hamcrest.SelfDescribing class? Something to do with mocks? OK, fine. But why the dependency? I'm not doing anything at all with it. This is literally a Java project with no dependencies other than JUnit. Stumped (and frustrated)!!

• Error when opening .tar.gz via Shell to install Apache Maven

  - by adamsquared

  Thank you in advance for the help. My Goal: To install apache maven per its websites instructions (http://maven.apache.org/download.html), in order to install the JUNG package according to its install instructions (http://sourceforge.net/apps/trac/jung/wiki/JUNGManual), so I can use the JUNG classes in various Java GUIs. The Problem: I get an error message when I try to extract the apache-maven .gz (install?) file in shell. Background: I'm trying to install the JUNG (http://jung.sourceforge.net/index.html) package to my system's Java, so I can write object-oriented code using various GUIs (Ecliplse, Dr. Java) using the classes in JUNG. I don't understand how the building/installing process works, and how I can get what I build/install to work on various GUIs and the command line. I'm new to shell and the command line, and mostly have experience using a simple IDE (DrJava, Python IDLE, R GUI) to write and compile object-oriented code. Machine: Mac OSX 10.5.8 32-bit. The Instructions: For the maven building Extract the distribution archive, i.e. apache-maven-3.0.4-bin.tar.gz to the directory you wish to install Maven 3.0.4. These instructions assume you chose /usr/local/apache-maven. The subdirectory apache-maven-3.0.4 will be created from the archive. ... for the JUNG installation Appendix: How to Build JUNG This is a brief intro to building JUNG jars with maven2 (the build system that JUNG currently uses). First, ensure that you have a JDK of at least version 1.5: JUNG 2.0+ requires Java 1.5+. Ensure that your JAVA_HOME variable is set to the location of the JDK. On a Windows platform, you may have a separate JRE (Java Runtime Environment) and JDK (Java Development Kit). The JRE has no capability to compile Java source files, so you must have a JDK installed. If your JAVA_HOME variable is set to the location of the JRE, and not the location of the JDK, you will be unable to compile. Get Maven Download and install maven2 from maven.apache.org: http://maven.apache.org/download.html At time of writing (early December 2009), the latest version was maven-2.2.1. Install the downloaded maven2 (there are installation instructions on the Maven website). Follow the installation instructions and confirm a successful installation by typing 'mvn --version' in a command terminal window. Get JUNG ... What I Did: I downloaded the file apache-maven-2.2.1-bin.tar.gz. The JUNG website specified to use apache maven 2. I wanted to stick to the recommended installation instructions, but I couldn't get to /usr on my GUI (i've noticed you click on the MacHD symbol on the desktop its missing several directories/folders that you can see using the shell using the ls command at root directory I couldn't find a way to access the file using my mac GUI. Therefore, I used the shell to navigate to the root directory and then to /usr/local, and used the mkdir command to make the directory apache-maven and entered it. I then moved the file using the mv command. Next I tried extracting the file using tar -zxvf apache-maven-2.2.1-bin.tar.gz. The Error Message: tar: apache-maven-2.2.1/direcoryandfile: Cannot open: No such file or directory ... apache-maven-2.2.1/lib/ext: Cannot mkdir: No such file or directory apache-maven-2.2.1/lib/ext/README.txt tar: apache-maven-2.2.1/lib/ext/README.txt: Cannot open: No such file or directory tar: Error exit delayed from previous errors From what I can tell the archive file is missing some directories or something. I tried deleting the file, redownloading the .tar.gz file from a different mirror and repeating the process. Same result. Thanks again for the help

This works as follows: User clicks "Order now" in the windows app App uploads a file with POST to a PHP script The script immediately calls the PHP mail() function (order is not stored in a db) This works fine most of the time. However, sometimes a big delay occurs (several days). Customers calls why the product has not yet been delivered. E-mail headers of delayed mail follows: Microsoft Mail Internet Headers Version 2.0 Received: from barracuda.nkl.nl ([10.0.0.1]) by smtp.nkl.nl with Microsoft SMTPSVC(6.0.3790.3959); Wed, 26 May 2010 16:26:51 +0200 X-ASG-Debug-ID: 1274883818-2f8800000000-X58hIK X-Barracuda-URL: http://10.0.0.1:8000/cgi-bin/mark.cgi Received: from server45.firstfind.nl (localhost [127.0.0.1]) by barracuda.nkl.nl (Spam & Virus Firewall) with ESMTP id ECAFD15776A for <[email protected]>; Wed, 26 May 2010 16:23:38 +0200 (CEST) Received: from server45.firstfind.nl (server45.firstfind.nl [93.94.226.76]) by barracuda.nkl.nl with ESMTP id 85bAT2AU58kkxjPb for <[email protected]>; Wed, 26 May 2010 16:23:38 +0200 (CEST) X-Barracuda-Envelope-From: [email protected] Received: from server45.firstfind.nl (localhost [127.0.0.1]) by server45.firstfind.nl (8.13.8/8.13.8/Debian-3+etch1) with ESMTP id o4QEM3Hb004301 for <[email protected]>; Wed, 26 May 2010 16:23:31 +0200 Received: (from nklsemin@localhost) by server45.firstfind.nl (8.13.8/8.13.8/Submit) id o4J9lA7M031307; Wed, 19 May 2010 11:47:10 +0200 Date: Wed, 19 May 2010 11:47:10 +0200 Message-Id: <[email protected]> To: [email protected] X-ASG-Orig-Subj: easyfit - ref: Hoen3443 Subject: easyfit - ref: Hoen3443 X-PHP-Script: www.nklseminar.nl/emailer/upload.php for 77.61.220.217 From: [email protected] Content-type: text/html X-Virus-Scanned: by amavisd-new X-Barracuda-Connect: server45.firstfind.nl[93.94.226.76] X-Barracuda-Start-Time: 1274883820 X-Barracuda-Bayes: INNOCENT GLOBAL 0.0000 1.0000 -2.0210 X-Barracuda-Virus-Scanned: by Barracuda Spam & Virus Firewall at nkl.nl X-Barracuda-Spam-Score: 0.92 X-Barracuda-Spam-Status: No, SCORE=0.92 using global scores of TAG_LEVEL=2.0 QUARANTINE_LEVEL=1000.0 KILL_LEVEL=3.0 tests=DATE_IN_PAST_96_XX, DATE_IN_PAST_96_XX_2, HTML_MESSAGE, MIME_HEADER_CTYPE_ONLY, MIME_HTML_ONLY, NO_REAL_NAME X-Barracuda-Spam-Report: Code version 3.2, rules version 3.2.2.30817 Rule breakdown below pts rule name description ---- ---------------------- -------------------------------------------------- 0.00 NO_REAL_NAME From: does not include a real name 0.01 DATE_IN_PAST_96_XX Date: is 96 hours or more before Received: date 0.00 MIME_HTML_ONLY BODY: Message only has text/html MIME parts 0.00 HTML_MESSAGE BODY: HTML included in message 0.86 MIME_HEADER_CTYPE_ONLY 'Content-Type' found without required MIME headers 2.07 DATE_IN_PAST_96_XX_2 DATE_IN_PAST_96_XX_2 Return-Path: [email protected] X-OriginalArrivalTime: 26 May 2010 14:26:51.0343 (UTC) FILETIME=[7B80DDF0:01CAFCDF] The delay seems to occur here: Received: from server45.firstfind.nl (localhost [127.0.0.1]) by server45.firstfind.nl (8.13.8/8.13.8/Debian-3+etch1) with ESMTP id o4QEM3Hb004301 for <[email protected]>; Wed, 26 May 2010 16:23:31 +0200 Received: (from nklsemin@localhost) by server45.firstfind.nl (8.13.8/8.13.8/Submit) id o4J9lA7M031307; Wed, 19 May 2010 11:47:10 +0200 I've reported this issue various times to the web hosting service that hosts my website. They say the delay does not occur in their network (impossible). But they do confirm that the e-mail is first seen in their mail server on May 26, which is 7 days after the mail has been composed. The order is marked with the timestamp of the user's local PC, which also matches May 19 (so it's not a PC clock problem) It's also interesting to see that all delayed mails (orders were placed on different days) come in at once. So I suddenly receive 14 e-mail in my mailbox from various days. Any idea were this delay may be introduced? Could there be a bug in my PHP code that causes this? (I cannot believe I can introduce a loop of 7 days in my PHP code)

• linux script, standard directory locations.

  - by Thingomy

  I am trying to write a bash script to do a task, I have done pretty well so far, and have it working to an extent, but I want to set it up so it's distributable to other people, and will be opening it up as open source, so I want to start doing things the "conventional" way. Unfortunately I'm not all that sure what the conventional way is. Ideally I want a link to an in depth online resource that discusses this and surrounding topics in depth, but I'm having difficulty finding keywords that will locate this on google. At the start of my script I set a bunch of global variables that store the names of the dirs that it will be accessing, this means that I can modify the dir's quickly, but this is programming shortcuts, not user shortcuts, I can't tell the users that they have to fiddle with this stuff. Also, I need for individual users' settings not to get wiped out on every upgrade. Questions: Name of settings folder: ~/.foo/ -- this is well and good, but how do I keep my working copy and my development copy separate? tweek the reference in the source of the dev version? If my program needs to maintain and update library of data (gps tracklog data in this case) where should this directory be? the user will need to access some of this data, but it's mostly for internal use. I personally work in cygwin, and I like to keep this data on separate drive, so the path is wierd, I suspect many users could find this. for a default however I'm thinking ~/gpsdata/ -- would this be normal, or should I hard code a system that ask the user at first run where to put it, and stores this in the settings folder? whatever happens I'm going ot have to store the directory reference in a file in the settings folder. The program needs a data "inbox" that is a folder that the user can dump files, then run the script to process these files. I was thinking ~/gpsdata/in/ ?? though there will always be an option to add a file or folder to the command line to use that as well (it processed files all locations listed, including the "inbox") Where should the script its self go? it's already smart enough that it can create all of it's ancillary/settings files (once I figure out the "correct" directory) if run with "./foo --setup" I could shove it in /usr/bin/ or /bin or ~/.foo/bin (and add that to the path) what's normal? I need to store login details for a web service that it will connect to (using curl -u if it matters) plan on including a setting whereby it asks for a username and password every execution, but it currently stores it plane text in a file in ~/.foo/ -- I know, this is not good. The webservice (osm.org) does support oauth, but I have no idea how to get curl to use it -- getting curl to speak to the service in the first place was a hack. Is there a simple way to do a really basic encryption on a file like this to deter idiots armed with notepad? Sorry for the list of questions, I believe they are closely related enough for a single post. This is all stuff that stabbing at, but would like clarification/confirmation over.

• Problem with script to add/delete from database

  - by Jason

  Ok - the user enters a product code, price and name using a form - the script then either adds it to the database or deletes it from the database. If the user is trying to delete a product that is not in the database they get a error message. Upon successful adding/deleting they also get a message. However, when I test it - I just get a blank page. Perl doesnt come up with any warnings, syntax errors or anything - says everything is fine... but I still just get a blank page. The script... #!/usr/bin/perl #c09ex5.cgi - saves data to and removes data from a database print "Content-type: text/html\n\n"; use CGI qw(:standard); use SDBM_File; use Fcntl; use strict; #declare variables my ($code, $name, $price, $button, $codes, $names, $prices); #assign values to variables $code = param('Code'); $name = param('Name'); $price = param('Price'); $button = param('Button'); ($code, $name, $price) = format_input(); ($codes, $names, $prices) = ($code, $name, $price); if ($button eq "Save") { add(); } elsif ($button eq "Delete") { remove(); } exit; sub format_input { $codes =~ s/^ +//; $codes =~ s/ +$//; $codes =~ tr/a-z/A-Z/; $codes =~ tr/ //d; $names =~ s/^ +//; $names =~ s/ +$//; $names =~ tr/ //d; $names = uc($names); $prices =~ s/^ +//; $prices =~ s/ +$//; $prices =~ tr/ //d; $prices =~ tr/$//d; } sub add { #declare variable my %candles; #open database, format and add record, close database tie(%candles, "SDBM_File", "candlelist", O_CREAT|O_RDWR, 0666) or die "Error opening candlelist. $!, stopped"; format_vars(); $candles{$codes} = "$names,$prices"; untie(%candles); #create web page print "<HTML>\n"; print "<HEAD><TITLE>Candles Unlimited</TITLE></HEAD>\n"; print "<BODY>\n"; print "<FONT SIZE=4>Thank you, the following product has been added.<BR>\n"; print "Candle: $codes $names $prices</FONT>\n"; print "</BODY></HTML>\n"; } #end add sub remove { #declare variables my (%candles, $msg); tie(%candles, "SDBM_File", "candlelist", O_RDWR, 0) or die "Error opening candlelist. $!, stopped"; format_vars(); #determine if the product is listed if (exists($candles{$codes})) { delete($candles{$codes}); $msg = "The candle $codes $names $prices has been removed."; } else { $msg = "The product you entered is not in the database"; } #close database untie(%candles); #create web page print "<HTML>\n"; print "<HEAD><TITLE>Candles Unlimited</TITLE></HEAD>\n"; print "<BODY>\n"; print "<H1>Candles Unlimited</H1>\n"; print "$msg\n"; print "</BODY></HTML>\n"; }

• jquery live problem

  - by Kay

  Hi, I have a website which uses jquery and lots of mouseover/mouseout effect. So far I used the .bind() method of jquery but if you have 1000 event handlers, this is slowing down your browser a lot. So, I want to move to use .live or .delegate. One part of my portal site is a chat area. User can set chat messages which will then be displayed in a simple table. There is a feature that if you move the mouse over a chat message a trash can will appear allowing you to delete the message (if it is by you or you are a moderator). The trash bin is in the same table cell as the chat message. The problem: Using .bind() it worked like a charm. This is the old code: function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; a.appendChild(img); ctrl.appendChild(a); $(ctrl) .bind('mouseover', function(event) { $('#aDeleteChatMessage' + messageID).show() }) .bind('mouseout', function(event) { $('#aDeleteChatMessage' + messageID).hide() }); return; } 'ctrl' is the reference to a table cell. Now, using .live() the trashbin also appears but it is flickering a lot and when I move the mouse over the trashbin, it is disappearing or inactive. I have the feeling that more events are thrown or something. It seems like the 'mouseout' is thrown when moving over the trashbin, but the thrashbin is inside the tablecell so mouseout should not be triggered. The new code is as follows. $(document).ready { $('.jDeleteableChatMessage').live('mouseover mouseout', function(event) { var linkID = '#aDelete' + event.target.id; if (event.type == 'mouseover') { $(linkID).show(); } else { $(linkID).hide(); } return false; }); } function CreateChatMessageContextMenu(ctrl, messageID, message, sender) { if (!UserIsModerator && (UserLogin != sender)) return; ctrl.id = 'ChatMessage' + messageID; var deleteString = 'Diese Chatnachricht löschen'; if (UserLang == '1') deleteString = 'Delete this chat message'; var a = document.createElement("a"); a.href = "javascript:RemoveChatMessage(" + messageID + ");" a.id = 'aDeleteChatMessage' + messageID; a.style.display = 'none'; var img = document.createElement("span"); img.className = "sprite-common messages-image sprite-common-btnDelete"; img.alt = deleteString; img.title = deleteString; a.appendChild(img); ctrl.appendChild(a); $(ctrl).addClass('jDeleteableChatMessage'); } I add a class to tell jQuery which chat cell have a trash bin and which don't. I also add an ID to the table cell which is later used to determine the associated trash bin. Yes, that's clumsy data passing to an event method. And, naturally, there is the document.ready function which initialises the .live() method. So, where is my mistake?

• Friends Don’t Let Friends Play with Portal Guns [Video]

  - by Jason Fitzpatrick

  Many Portal fan films are sci-fi stories in their own right; this humorous video is simply focused on what happens when three guys get their hands on a portal gun. Jason Craft, the video’s director, explains: My interpretation of what a real POrtal gun would be like if one existed. Based on the video game, POrtal. I tried to match the game as close as possible. This was the most challenging project I have ever undertaken, consisting of 3D tracking, seamless camera cuts and 3D camera projection. ENJOY! We certainly wish our goofing around with friends videos came off this polished. For those of you wondering how he got such an awesome Portal Gun prop, it’s all CGI (you can check out his model here). [via Boing Boing] HTG Explains: What Is Windows RT & What Does It Mean To Me?

• Building a regex builder

  - by i.h4d35

  I am a beginner in programming in general and web development in particular. I am especially bad at regular expressions. Recently I was involved in building a couple of cPanel plugins(Perl-CGI) and that's when I realized how bad I am in regex. As a result, I have decided to build an online regex builder - this will help me to learn regex and help other struggling with regex. I have checked out GSkinner, Rubular and a couple of others like regexpal. It seemed to be a little difficult to use, hence i thought of writing another one. I do not know which tool is best suited for the job. should I write it in Perl or Python? My skill level is between beginner and intermediate in both those languages. What would be a good starting point - building it for the CLI or for the browser? I plan to get a string as an input, ask if the user want to search or search and replace, enter the search string (and the replace string where applicable) and then generate a regex. Would this be the right way to go?

• Advice for a computer science sophomore in college?

  - by RDas

  Hi Everyone! I'm a sophomore in college majoring in Computer Science and Math. I have always loved programming. I started programming in C when I was nine years old and over the years I've picked up Visual Basic, C#, Java, C++, JavaScript, Objective-C, Python, Ruby, elementary Haskell and elementary Erlang, and I learned Perl back in the day which I've mostly forgotten. I have not done much network programming. I have done CGI programming, but that was about six/seven years ago. I've done some socket programming and written (school) programs to do interprocess communication, which I understood and liked. I'm taking a course on client/server programming and another one on network security next semester, which I am really looking forward to. I'm seeking advice on how to proceed with future learning. I've mostly done application (mobile and desktop) development, not much of web development. I'd like to pick up some web development this coming semester. Since I know Ruby and Python, should I start by learning Django and/or Rails? Any other suggestions on starting web development? I have a good understanding of HTML and CSS. Also, I'd also like to know how hard it is to pick up and be good (read: productive) in functional programming languages coming from a purely structured/object oriented background? I've been reading up on Erlang and Haskell, and I'd like to know your opinions on whether it's worth my time trying to learn them. What about Lisp, Scheme and other functional languages? Any help/ideas would be really appreciated.

• ODEE Green Field (Windows) Part 5 - Deployment and Validation

  - by AndyL-Oracle

  And here we are, almost finished with our installation of Oracle Documaker Enterprise Edition ("ODEE") in a Windows green field environment. Let's recap what we've done so far: In part 1, I went over the basic process that I intended to show with installing an ODEE on a green field server. I walked you through the basic installation of Oracle 11g database In part 2, I covered the installation of WebLogic application server. In part 3, I showed you how to install SOA Suite for WebLogic. In part 4, we did the first part of the installation of ODEE itself. What remains after all of that, is the deployment of the ODEE components onto the database and application server - so let's get to it! DATABASE First, we'll deploy the schemas to the database. The schemas are created during the ODEE installation according to the responses provided during the install process. To deploy the schemas, you'll need to login to the database server in your green field environment. Open a command line and CD into ODEE_HOME\documaker\database\oracle11g.Run SQLPLUS as SYSDBA and execute dmkr_admin.sql:  sqlplus / as sysdba @dmkr_admin.sql Execute dmkr_asline.sql, dmkr_admin_correspondence_example.sql.  If you require additional languages, run the appropriate SQL scripts (e.g. dmkr_asline_es.sql for Spanish). APPLICATION SERVER Next, we'll deploy the WebLogic domain and it's components - Documaker web services, Documaker Interactive, Documaker dashboard, and more. To deploy the components, you'll need to login to the application server in your green field environment. 1. Open Windows Explorer and navigate to ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts.2. Using a text editor such as Notepad++, modify weblogic_installation_properties and set location of MIDDLEWARE_HOME and ODEE HOME. If you have used the defaults you’ll probably need to change the E: to C: and that’s it. Save the changes.3. Continuing in the same directory, use your text editor to modify set_middleware_env.cmd and set the drive and path to MIDDLEWARE_HOME. If you have used the defaults you’ll probably need to just change E: to C: and that’s it. Save the changes.4. In the same directory, execute wls_create_domain.cmd by double-clicking it. This should run to completion. If it does not, review any errors and correct them, and rerun the script.5. In the same directory, execute wls_add_correspondence.cmd by double-clicking it - again this should run to completion. 6. Next, we'll start the AdminServer - this is the main WebLogic domain server. To start it, use Windows Explorer and navigate to MIDDLEWARE_HOME\user_projects\domains\idocumaker_domain. Double-click startWebLogic.cmd and the server startup will begin. Once you see output that indicates that the server status changed to RUNNING you may proceed.  a. Note: if you saw database connection errors, you probably didn’t make sure your database name and connection type match. You can change this manually in the WebLogic Console. Open a browser and navigate to http://localhost:7001/console (replace localhost with the name of your application server host if you aren't opening the browser on the server), and login with the the weblogic credential you provided in the ODEE installation process. b. Once you're logged in, open Services?Data Sources. Select dmkr_admin and click Connection Pool.  c. The end of the URL should match the connection type you chose. If you chose ServiceName, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<serviceName> and if you chose SID, the URL should be: jdbc:oracle:thin:@//<hostname>:1521/<SIDname> d. An example serviceName is a fully qualified DNS-style name, e.g. "idmaker.us.oracle.com". (It does not need to actually resolve in DNS). An example SID is just a name, e.g. IDMAKER. e. Save the change and repeat for the data source dmkr_asline.  f. You will also need to make the same changes in the ODEE_HOME/documaker/docfactory/config/context/.bindings file - open the file in a text editor, locate the URL lines and make the appropriate change, then save the file.  7. Back in the ODEE_HOME\documaker\j2ee\weblogic\oracle11g\scripts directory, execute create_users_groups.cmd. 8. In the same directory, execute create_users_groups_correspondence_example.cmd. 9. Open a browser and navigate to http://localhost:7001/jpsquery. Replace localhost with the name of your application server host if you aren't running the browser on the application server. If you changed the default port for the AdminServer from 7001, use the port you changed it to. You should see output like this: 10. Start the WebLogic managed servers by opening a command prompt and navigating to MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/. When you start the servers listed below, you will be prompted to enter the WebLogic credentials to start the server. You can prevent this by providing the credential in the startManagedwebLogic.cmd file for the WLS_USER and WLS_PASS values. Note that the credential will be stored in cleartext. To start the server, type in the command shown. a. Start the JMS Server: ./startManagedWebLogic.cmd jms_server b. Start Dashboard/Documaker Administrator: ./startManagedWebLogic.cmd dmkr_server c. Start Documaker Interactive for Correspondence: ./startManagedWebLogic.cmd idm_server SOA Composites  If you're planning on testing out the approval process components of BPEL that can be used with Documaker Interactive, then use the following steps to deploy the SOA composites. If you're not going to use BPEL, you can skip to the next section.1. Stop the servers listed in the previous section (Step 10) in the reverse order that they were started.2. Run the Domain configuration command: navigate to and execute MIDDLEWARE_HOME/wlserver_10.3/common/bin/config.cmd.3. Select Extend and click next. 4. Select the iDocumaker Domain and click Next. 5. Select the Oracle SOA Suite – 11.1.1.0 (this may automatically select other components which is OK). Click Next. 6. View the Configure JDBC resources screen. You should not make any changes. Click Next. 7. Check both connections and click Test Connections. After successful test, click Next. If the tests fail, something is broken. Go back to configure JDBC resources and check your service name/SID. 8. Check all schemas. Set a password (will be the same for all schemas). Enter the database information (service name, host name, port). Click Next. 9. Connections should test successfully. If not, go back and fix any errors. Click Next. 10. Click Next to pass through Optional Configuration. 11. Click Extend. 12. Click Done. 13. Open a terminal window and navigate to/execute: ODEE_HOME/documaker/j2ee/weblogic/oracle11g/bpel/antbuild.cmd14. Start the WebLogic Servers – AdminServer, jms_server, dmkr_server, idm_server. If you forgot how to do this, see the previous section Step 10. Note: if you previously changed the startManagedWebLogic.cmd script for WLS_USER and WLS_PASS you will need to make those changes again. 15. Start the WebLogic server soa_server1: MIDDLEWARE_HOME/user_projects/domains/idocumaker_domain/bin/startManagedWebLogic.cmd soa_server116. Open a browser to http://localhost:7001/console and login. 17. Navigate to Services?Data Sources and select DMKR_ASLINE. 18. Click the Targets tab. Check soa_server1, then click Save. Repeat for the DMKR_ADMIN data source. 19. Open a command prompt and navigate to ODEE_HOME/j2ee/weblogic/oracle11g/scripts, then execute deploy_soa.cmd. That's it! (As if that wasn't enough?) DOCUMAKER Deploy the sample MRL resources by navigating to/executing ODEE_HOME/documaker/mstrres/dmres/deploysamplemrl.bat. You should see approximately 500 resources deployed into the database. Start the Factory Services. Start?Run?services.msc. Locate the service named "ODDF xxxx" and right-click, select Start. Note that each Assembly Line has a separate Factory setup, including its own Factory service and Docupresentment service. The services are named for the assembly line and the machine on which they are installed (because you could have multiple machines servicing a single assembly line, so this allows for easy scripting to control all the services if you choose to do so. Repeat for the Docupresentment service. Note that each Assembly Line has a separate Docupresentment. Using Windows Explorer, navigate to ODEE_HOME/documaker/mstrres/dmres/input and select one of the XML files, and copy it into ODEE_HOME/documaker/hotdirectory. Note: if you chose a different hot directory during installation, copy the file there instead. Momentarily you should see the XML file disappear! Open browser and navigate to http://localhost:10001/DocumakerDashboard (previous versions 12.0-12.2 use http://localhost:10001/dashboard) and verify that job processed successfully. Note that some transactions may fail if you do not have a properly configured email server, and this is ok. You can set up a simple SMTP server (just search the internet for "SMTP developer" and you'll get several to choose from.  So... that's it? Where are we at this point? You now have a completely functional ODEE installation, from soup to nuts as they say. You can further expand your installation by doing some of the following activities: clustering WebLogic services configuring WebLogic for redundancy configuring Oracle 11g for RAC adding additional Factory servers for redundancy/processing capacity setting up a real MRL (instead of the sample resources) testing Documaker Web Services for job submission and more!  I certainly hope you've enjoyed this and find it useful. If you find yourself running into trouble, visit the Oracle Community for Documaker - there is plenty of activity there and you can ask questions. For more concentrated assistance, you can engage an Oracle consultant who is a subject matter expert to assist you. Feel free to email me [andy (dot) little (at) oracle (dot) com] and I can connect you with the appropriate resource to get started. Best of luck! -Andy

• Explain Model View Controller

  - by Channel72

  My experience with developing dynamic websites is limited mostly to Java servlets. I've used Tomcat to develop various Java servlets, and I wouldn't hesitate to say that I'm reasonably proficient with this technology, as well as with client-side HTML/CSS/Javascript for the front-end. When I think "dynamic website", I think: user requests a URL with a query string, server receives the query, and then proceeds to output HTML dynamically in order to respond to the query. This often involves communication with a database in order to fetch requested data for display. This is basically the idea behind the doGet method of a Java HttpServlet. But these days, I'm hearing more and more about newer frameworks such as Django and Ruby on Rails, all of which take advantage of the "Model View Controller" architecture. I've read various articles which explain MVC, but I'm having trouble really understanding the benefits. I understand that the general idea is to separate business logic from UI logic, but I fail to see how this is anything really different from normal web programming. Web programming, by it's very nature, forces you to separate business logic (back-end server-side programming) from UI programming (client-side HTML or Javascript), because the two exist in entirely different spheres of programming. Question: What does MVC offer over something like a Java servlet, and more importantly, what exactly is MVC and how is it different from what you would normally do to develop a dynamic website using a more traditional approach such as a Java servlet (or even something older like CGI). If possible, when explaining MVC, please provide an example which illustrates how MVC is applied to the web development process, and how it is beneficial.

• Unable to cast transparent proxy to type &lt;type&gt;

  - by Rick Strahl

  This is not the first time I've run into this wonderful error while creating new AppDomains in .NET and then trying to load types and access them across App Domains. In almost all cases the problem I've run into with this error the problem comes from the two AppDomains involved loading different copies of the same type. Unless the types match exactly and come exactly from the same assembly the typecast will fail. The most common scenario is that the types are loaded from different assemblies - as unlikely as that sounds. An Example of Failure To give some context, I'm working on some old code in Html Help Builder that creates a new AppDomain in order to parse assembly information for documentation purposes. I create a new AppDomain in order to load up an assembly process it and then immediately unload it along with the AppDomain. The AppDomain allows for unloading that otherwise wouldn't be possible as well as isolating my code from the assembly that's being loaded. The process to accomplish this is fairly established and I use it for lots of applications that use add-in like functionality - basically anywhere where code needs to be isolated and have the ability to be unloaded. My pattern for this is: Create a new AppDomain Load a Factory Class into the AppDomain Use the Factory Class to load additional types from the remote domain Here's the relevant code from my TypeParserFactory that creates a domain and then loads a specific type - TypeParser - that is accessed cross-AppDomain in the parent domain:public class TypeParserFactory : System.MarshalByRefObject,IDisposable { …/// <summary> /// TypeParser Factory method that loads the TypeParser /// object into a new AppDomain so it can be unloaded. /// Creates AppDomain and creates type. /// </summary> /// <returns></returns> public TypeParser CreateTypeParser() { if (!CreateAppDomain(null)) return null; /// Create the instance inside of the new AppDomain /// Note: remote domain uses local EXE's AppBasePath!!! TypeParser parser = null; try { Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); } catch (Exception ex) { this.ErrorMessage = ex.GetBaseException().Message; return null; } return parser; } private bool CreateAppDomain(string lcAppDomain) { if (lcAppDomain == null) lcAppDomain = "wwReflection" + Guid.NewGuid().ToString().GetHashCode().ToString("x"); AppDomainSetup setup = new AppDomainSetup(); // *** Point at current directory setup.ApplicationBase = AppDomain.CurrentDomain.BaseDirectory; //setup.PrivateBinPath = Path.Combine(AppDomain.CurrentDomain.BaseDirectory, "bin"); this.LocalAppDomain = AppDomain.CreateDomain(lcAppDomain,null,setup); // Need a custom resolver so we can load assembly from non current path AppDomain.CurrentDomain.AssemblyResolve += new ResolveEventHandler(CurrentDomain_AssemblyResolve); return true; } …} Note that the classes must be either [Serializable] (by value) or inherit from MarshalByRefObject in order to be accessible remotely. Here I need to call methods on the remote object so all classes are MarshalByRefObject. The specific problem code is the loading up a new type which points at an assembly that visible both in the current domain and the remote domain and then instantiates a type from it. This is the code in question:Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; parser = (TypeParser) this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); The last line of code is what blows up with the Unable to cast transparent proxy to type <type> error. Without the cast the code actually returns a TransparentProxy instance, but the cast is what blows up. In other words I AM in fact getting a TypeParser instance back but it can't be cast to the TypeParser type that is loaded in the current AppDomain. Finding the Problem To see what's going on I tried using the .NET 4.0 dynamic type on the result and lo and behold it worked with dynamic - the value returned is actually a TypeParser instance: Assembly assembly = Assembly.GetExecutingAssembly(); string assemblyPath = Assembly.GetExecutingAssembly().Location; object objparser = this.LocalAppDomain.CreateInstanceFrom(assemblyPath, typeof(TypeParser).FullName).Unwrap(); // dynamic works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // casting fails parser = (TypeParser)objparser; So clearly a TypeParser type is coming back, but nevertheless it's not the right one. Hmmm… mysterious.Another couple of tries reveal the problem however:// works dynamic dynParser = objparser; string info = dynParser.GetVersionInfo(); // method call works // c:\wwapps\wwhelp\wwReflection20.dll (Current Execution Folder) string info3 = typeof(TypeParser).Assembly.CodeBase; // c:\program files\vfp9\wwReflection20.dll (my COM client EXE's folder) string info4 = dynParser.GetType().Assembly.CodeBase; // fails parser = (TypeParser)objparser; As you can see the second value is coming from a totally different assembly. Note that this is even though I EXPLICITLY SPECIFIED an assembly path to load the assembly from! Instead .NET decided to load the assembly from the original ApplicationBase folder. Ouch! How I actually tracked this down was a little more tedious: I added a method like this to both the factory and the instance types and then compared notes:public string GetVersionInfo() { return ".NET Version: " + Environment.Version.ToString() + "\r\n" + "wwReflection Assembly: " + typeof(TypeParserFactory).Assembly.CodeBase.Replace("file:///", "").Replace("/", "\\") + "\r\n" + "Assembly Cur Dir: " + Directory.GetCurrentDirectory() + "\r\n" + "ApplicationBase: " + AppDomain.CurrentDomain.SetupInformation.ApplicationBase + "\r\n" + "App Domain: " + AppDomain.CurrentDomain.FriendlyName + "\r\n"; } For the factory I got: .NET Version: 4.0.30319.239wwReflection Assembly: c:\wwapps\wwhelp\bin\wwreflection20.dllAssembly Cur Dir: c:\wwapps\wwhelpApplicationBase: C:\Programs\vfp9\App Domain: wwReflection534cfa1f For the instance type I got: .NET Version: 4.0.30319.239wwReflection Assembly: C:\\Programs\\vfp9\wwreflection20.dllAssembly Cur Dir: c:\\wwapps\\wwhelpApplicationBase: C:\\Programs\\vfp9\App Domain: wwDotNetBridge_56006605 which clearly shows the problem. You can see that both are loading from different appDomains but the each is loading the assembly from a different location. Probably a better solution yet (for ANY kind of assembly loading problem) is to use the .NET Fusion Log Viewer to trace assembly loads.The Fusion viewer will show a load trace for each assembly loaded and where it's looking to find it. Here's what the viewer looks like: The last trace above that I found for the second wwReflection20 load (the one that is wonky) looks like this:*** Assembly Binder Log Entry (1/13/2012 @ 3:06:49 AM) *** The operation was successful.

WRN: It is recommended to inspect your application on whether this is intentional or not. WRN: See whitepaper http://go.microsoft.com/fwlink/?LinkId=109270 for more information and common solutions to this issue. Notice that the fusion log clearly shows that the .NET loader makes no attempt to even load the assembly from the path I explicitly specified. Remember your Assembly Locations As mentioned earlier all failures I've seen like this ultimately resulted from different versions of the same type being available in the two AppDomains. At first sight that seems ridiculous - how could the types be different and why would you have multiple assemblies - but there are actually a number of scenarios where it's quite possible to have multiple copies of the same assembly floating around in multiple places. If you're hosting different environments (like hosting the Razor Engine, or ASP.NET Runtime for example) it's common to create a private BIN folder and it's important to make sure that there's no overlap of assemblies. In my case of Html Help Builder the problem started because I'm using COM interop to access the .NET assembly and the above code. COM Interop has very specific requirements on where assemblies can be found and because I was mucking around with the loader code today, I ended up moving assemblies around to a new location for explicit loading. The explicit load works in the main AppDomain, but failed in the remote domain as I showed. The solution here was simple enough: Delete the extraneous assembly which was left around by accident. Not a common problem, but one that when it bites is pretty nasty to figure out because it seems so unlikely that types wouldn't match. I know I've run into this a few times and writing this down hopefully will make me remember in the future rather than poking around again for an hour trying to debug the issue as I did today. Hopefully it'll save some of you some time as well in the future.© Rick Strahl, West Wind Technologies, 2005-2012Posted in .NET  COM   Tweet !function(d,s,id){var js,fjs=d.getElementsByTagName(s)[0];if(!d.getElementById(id)){js=d.createElement(s);js.id=id;js.src="//platform.twitter.com/widgets.js";fjs.parentNode.insertBefore(js,fjs);}}(document,"script","twitter-wjs"); (function() { var po = document.createElement('script'); po.type = 'text/javascript'; po.async = true; po.src = 'https://apis.google.com/js/plusone.js'; var s = document.getElementsByTagName('script')[0]; s.parentNode.insertBefore(po, s); })();

• De-index URL parameters by value

  - by Doug Firr

  Upon reading over this question is lengthy so allow me to provide a one sentence summary: I need to get Google to de-index URLs that have parameters with certain values appended I have a website example.com with language translations. There used to be many translations but I deleted them all so that only English (Default) and French options remain. When one selects a language option a parameter is aded to the URL. For example, the home page: https://example.com (default) https://example.com/main?l=fr_FR (French) I added a robots.txt to stop Google from crawling any of the language translations: # robots.txt generated at http://www.mcanerin.com User-agent: * Disallow: Disallow: /cgi-bin/ Disallow: /*?l= So any pages containing "?l=" should not be crawled. I checked in GWT using the robots testing tool. It works. But under html improvements the previously crawled language translation URLs remain indexed. The internet says to add a 404 to the header of the removed URLs so the Googles knows to de-index it. I checked to see what my CMS would throw up if I visited one of the URLs that should no longer exist. This URL was listed in GWT under duplicate title tags (One of the reasons I want to scrub up my URLS) https://example.com/reports/view/884?l=vi_VN&l=hy_AM This URL should not exist - I removed the language translations. The page loads when it should not! I played around. I typed example.com?whatever123 It seems that parameters always load as long as everything before the question mark is a real URL. So if Google has indexed all these URLS with parameters how do I remove them? I cannot check if a 404 is being generated because the page always loads because it's a parameter that needs to be de-indexed.

• Apache Server-Side Includes Refuse to Work (Tried everything in the docs but still no joy)

  - by raindog308

  Trying to get apache server-side includes to work. Really simple - just want to include a footer on each page. Apache 2.2: # ./httpd -v Server version: Apache/2.2.21 (Unix) Server built: Dec 4 2011 18:24:53 Cpanel::Easy::Apache v3.7.2 rev9999 mod_include is compiled in: # /usr/local/apache/bin/httpd -l | grep mod_include mod_include.c And it's in httpd.conf: # grep shtml httpd.conf AddType text/html .shtml DirectoryIndex index.html.var index.htm index.html index.shtml index.xhtml index.wml index.perl index.pl index.plx index.ppl index.cgi index.jsp index.js index.jp index.php4 index.php3 index.php index.phtml default.htm default.html home.htm index.php5 Default.html Default.htm home.html AddHandler server-parsed .shtml AddType text/html .shtml In the web directory I created a .htaccess with Options +Includes And then in the document, I have: <h1>next should be the include</h1> <!--#include virtual="/footer.html" --> <h1>include done</h1> And I see nothing in between those headers. Tried file=, also with/without absolute path. Is there something else I'm missing? I see the same thing on another unrelated server (more or less stock CentOS 6), so I suspect the problem is between keyboard and chair...
