• Python 3-compatibe HTML to text converter preserving basic structure under permissive licence?

  - by hawk64

  I am looking for a relatively simple HTML to text converter which displays links and works on strings. So far I have tried lynx but performance is too bad, html2text which gives weird and verbose markdown output and is under GPLv3 which is too restrictive for my (BSD-licensed) project, http://effbot.org/librarybook/formatter-example-3.py using htmllib.HTMLParser with formatter.AbstractFormatter and a custom writer, however htmllib.HTMLParser is drpeceated and has been removed from Python 3. So is there any simple, performant, Python 3-compatible HTML to text converter under a permissive license such as MIT/BSD/Apache and the like? Edit: I dont just need something to strip HTML-Tags but also to preserve the basic structure of the HTML, that is output that somewhat resembles that of Lynx.

• Passing JS variable from child Iframe to parent JSP on cross sub domain

  - by Tarun

  I am stuck at 1 location and need some help. I created two subdomains on apache tomcat server like domain1.localhost.com and domain2.localhost.com in server.xml. On domain1 I have a JSP that includes iFrame (hosted on domain2). How can we pass the JS variable from child Iframe to parent JSP and store it in local variable of JSP hosted on domain1.localhost.com? I tried defining document.domain = "localhost" on both JSP but didn't work. Even parent DOM window is also not available in child iFrame (on sub-domain) because of obvious cross domain policies. Any help would be highly appreciated.

• Click events not working in Rails view

  - by Fdr

  I have following view (html.erb): <h3>My view</h3> <script> function test() { alert("hello"); } </script> <input type="button" onClick="test();" value="test" /> For reasons I cannot understand the onClick event never gets fired when I access the view through rails(tried static apache hosting - no problems there). Here is rendered html: http://pastebin.com/LmGysgUG I feel quite stupid, is this something to do the way Rails renders views?

• How do I give PHP write access to a directory?

  - by SGWebsNow

  I'm trying to use PHP to create a file, but it isn't working. I am assuming this is because it doesn't have write access (it's always been the problem before). I tried to test if this was the problem by making the folder chmod 0777, but that just ended up making every script in that directory return a 500 error message until I changed it back. How do I give PHP write access to my file system so it can a create a file? Edit: It is hosted on Hostgator shared hosting using Apache.

• What are the alternatives for Java authentication?

  - by Crusader

  Preferably something that integrates well with a Flex front end. Yes the Spring Security guys say this is possible, but all examples seem to use legacy jsp tag libraries making them half useless as examples. I don't want to spend a month setting up and learning how to use a security tool. I would like a tool which supports using annotations (@RolesAllowed etc), MINIMAL XML, and 'remember-me' features (not cookie based). Apache Shiro seems to support Flex/Silverlight/Swing as well but I'd like to know if there are any other alternatives that are NOT container specific.

• Maven/Ivy: Identical artifact with different name in dependency

  - by ThiamTeck

  Currently I am using Ivy for dependency management. And quite often I come across problem of getting identical jar files with different name due to transitive dependency. Example: <dependency> <groupId>javax.mail</groupId> <artifactId>mail</artifactId> <version>1.4</version> </dependency> <dependency> <groupId>org.apache.geronimo.specs</groupId> <artifactId>geronimo-javamail_1.4_spec</artifactId> <version>1.4</version> </dependency> I am thinking of trying out Maven as well. Any best practice to eliminate these identical artifact in either Ivy or Maven?

• Passing input to Ant's <exec> task

  - by mikek

  I have an Ant script running a standard -task after taking in an inputed password: <input message="Password:" addproperty="password"> <handler classname="org.apache.tools.ant.input.SecureInputHandler" /> </input> <exec executable="/bin/sh" input="${password}" failonerror="true"> <arg line='-c "myScript.sh"' /> </exec> The script myScript.sh prompts the user for a password, and, it was my understanding that from the Ant documentation that input is supposed relay input into whatever the <exec> task is executing, but instead I get (for entering the password foobar) [exec] Failed to open /usr/local/foobar which is followed by a stack trace from my script complaining about an incorrect password...so obviously I've understood the documentation wrong. Does anybody know how to handle prompted input from external scripts in Ant?

• Horizontal Scaling of Tomcat in Microsoft Azure

  - by Fabe

  Hey everyone, I am working on this quiet a while, but still no conclustion. I want to do horizontal scaling of Tomcat instances in Microsoft Azure (1,2,3,... Tomcat instances for one service). I read lots of articles about session replication, clustering,... with Tomcat. Since Azure does not support Multicasts, there is no easy way to cluster Tomcat. Also sticky sessions is no options, because Azure does round robin load balancing. Setting up two services - one with Terracotta or Apache mod_jk - and the other with Tomcat instances seems overkill for me (if even doable)... Is this even possible? Thanks in advance for reading and answering my question. Every comment/idea is highly appreciated.

• How can I use gtkmm with MinGW (g++) without MSYS?

  - by paycity

  Hello stackoverflow members, How can I use gtkmm with MinGW (g++) without MSYS? Here is the story of my problem: I installed MinGW offline with all required packages (full install). I installed Apache Server and I copied all .tar.gz files and I created a website called sourceforge.org [localhost] and I installed automatically MinGW on Windows XP. After, I set the PATH variables. After, I installed gtkmm for MinGW (g++). I tried to compile a simple window with gtkmm + MinGW, but it does not work. I use this command line: g++ simple.cc -o simple pkg-config gtkmm-2.4 --cflags --libs After, I installed MSYS and I can compile simple.cc with MSYS, using this command line: g++ simple.cc -o simple pkg-config gtkmm-2.4 --cflags --libs My problem: I want to compile simple.cc without MSYS. I want compile my simple.cc with cmd.exe - It's possbile? If, yes. How? Thank you for reading my message. Any help is appreciated.

• extending spring form tag library attributes

  - by TimmyJ

  I'm using Spring's form tag library in a Spring MVC application that I am developing. The company I am working for has implemented some company-wide policies based on the definition of custom attributes for certain tags. For instance, by default (though the inclusion of a standard javascript file) all tags have their values automatically converted to upper case. In order to disable this one would define their tag with a custom attribute in the following way: <input type="text" uppercase="false" /> The problem is that the addition of these custom attributes to a spring:form tag causes an error at runtime. I've pasted the error below. org.apache.jasper.JasperException: /WEB-INF/jsp/reportCriteria.jsp(45,5) Attribute uppercase invalid for tag input according to TLD My question is: is there any way to extend the TLD to allow for these attributes, or is there any other way add these custom attributes to these spring:form tags?

• Get Distance from geohash field in solr 3.6

  - by Omar A. Shaaban

  Is it possible to get distance returned from a geodist() filter, on a geohash field that has multiple values? The geosort and the geodist filter are working fine, but I'm trying to get the distance between the query point and a location that was returned in the result. I've tried http://wiki.apache.org/solr/SpatialSearch#Returning_the_distance The second method which is : //localhost:8983/solr/select?indent=true&fl=name,store&sfield=store&pt=45.15,-93.85&sort=score%20asc&q={!func}geodist() But it returns weird results, tested with 2 locations it returns score 9979.032, where there is ~33,000 Km between both points in reality? What is the unit that it uses returning the distance in the score field? I assumed km, but it does not make sense, or the result is bogus, I dunno Anyhelp would be appreciated, thanks

• timeline charts with rich ui

  - by Karthick R

  hi all, I have a requirement to come up with a time line chart and a few more controls on a single page[with rich ui]. I have short listed Flex, JSF[apache trinidad], html5, gwt these technologies. None of them provide timeline charts on their own. I am looking at other options such as using third party libraries. The chart should have drill down capabilities as well. Let me know if there is any specific technology that I should try. regards

• MyFaces Test Framework not working with JSF 2.1

  - by Karl Kildén

  we have a lot of tests that uses Myfaces Test Framework for JSF 2.0. http://myfaces.apache.org/test/index.html Problem is we can't get it to work with JSF 2.1. Does anyone know a workaround or a way to solve this? When we run the tests we get the following error: java.lang.IllegalStateException: Application was not properly initialized at startup, could not find Factory: javax.faces.application.ApplicationFactory It works fine with jsf 2.0 though. A typical use case in our code: // code block; assertFalse("Error message not expected. ", facesContext .getMessages().hasNext()); JSF 2.1 has a few syntax changes so my guess would be that's the problem.

• Making an asynchronous interface appear synchronous to mod_python users

  - by Trey

  I have a Python-driven web interface powered by Apache 2.2 with mod_python and Python 2.4. I need to make an asynchronous process appear synchronous to users of this web interface. When users access one module on this website: An external SOAP interface will be contacted with a unique identifier and will respond with a number N The external interface will respond asynchronously by contacting a SOAP server on my machine between 1 and 10 times (the number N tells us how many responses we will receive) I need to somehow aggregate these responses and pass them to the original module which will display the information back to the user. The goal is to make the process appear synchronous to the user. What is the best way to handle this synchronization issue? Is this something Twisted would be well-suited for? I am not restricting myself to Python for the solution, though it is preferred because everything else on the server is in Python. I prefer a solution that is both scalable and will take a minimal amount of programming time (though I understand that these attributes are somewhat at odds).

• Is it possible to optimize maven dependencies automatically?

  - by AlexR

  I am working on a big project that consists of about 40 sub-projects with very not optimized dependencies. There are declared dependencies that are not in use as well as used but undeclared dependencies. The second case is possible when dependency is added via other dependency. I want to remove redundant and add required dependencies. I ran mvn dependency:analyze and got a long list of warnings I have to fix now. I wonder whether there is maven plugin or any other utility that can update my pom.xml files automatically. I tried to do it manually but it takes a lot of time. It seems it will take a couple of days of copy/paste to complete the task. In worse case I can write such script myself but probably ready stuff exists? Here is how mvn dependency:analyze reports dependency warnings: [WARNING] Used undeclared dependencies found: [WARNING] org.apache.httpcomponents:httpcore:jar:4.1:compile [WARNING] Unused declared dependencies found: [WARNING] commons-lang:commons-lang:jar:2.4:compile [WARNING] org.json:json:jar:20090211:compile

• Why are most really fast servers written in C instead of C++?

  - by orokusaki

  I'm trying to decide which to learn and I've read all the "Which is better" questions/arguments, so I thought I'd get your take on something more specific. Is there a platform dependency issue that C++ developers run into with such applications? Or, is it because there are more C developers out there than C++? I also noticed that many more third party C modules exist for Python even thought C++ modules are supported. From what I've read on different threads the consensus is that C++ is easier and faster to write, and runs just as fast. Am I missing something really big. Examples: NGINX APE (comet server) Apache

• how to find out how much application memory django process is (or will be) taking?

  - by photographer

  There are different "Application memory" options (like 80MB...200MB) in django-friendly hosting called webfaction and I'm confused deciding which one I should buy. Could someone please walk me through the ideas on how to figure out how much memory my project might require (excluding operating system, the main apache server and the database servers memory requirements)? I understand in theory I'll need to perform some kind of load testing, but thought there might be ways to calculate that in advance with some simple/relatively easy understandable approach. I don't know how hard they enforce application memory usage limit, and another question is: what will happen if more users came to the site and more threads started than what I expected? Will the application crash? Or will delays just become uncomfortable? And - no, application is not ready yet (I can't measure anything right now). Development environment if it matters is Winodows 7, 64-bit. Hosting itself is some kind of Linux I think. (Sorry if it's not a stackoverflow question.)

• MySQL 5 in MySQL 4 compatible mode for one database?

  - by Horace Ho

  In a recent project, I have to maintain some PHP code. I set up a development server and installed MySQL, Apache, PHP, ..etc. The program is terminated with an error: Unknown column _ _ _ in 'on clause' Cannot select .... Google shows that it's a change of syntax around JOINs, parentheses are needed. As you may imagine, fixing all that PHP SQL strings will be the last resort. _< Is is possible to config MySQL 5 to run at MySQL 4 compatible mode? Or even better, for only one database? Thanks! p.s. Since we are going to host the code on a new production server (MySQL 5 on a CentOS box), the chance to install MySQL 4 on the new server might be slim.

• Which Subversion do I install for Windows?

  - by johnny

  I was reading this article on Coding Horror: http://www.codinghorror.com/blog/2008/04/setting-up-subversion-on-windows.html I went to the downloads and am confused. I would have just downloaded the first entry but I am afraid it would break my server or something if I don't have apache. We use IIS only and I wouldn't want to break it somehow. I don't even need a web or webdav front end. Which one should I install on this page, please: http://subversion.tigris.org/servlets/ProjectDocumentList?folderID=91 thank you for any help. edit: thanks for information, but I am hoping to stay free with the "regular" subversion. I plan on using TortoiseSVN for the client.

• Is there a 'hello world' website for django? OR (I've installed django, now what) ?

  - by morpheous

  I'm learning Python and decided to start familiarizing myself with the (defacto?) Python web framework - django. I have successfully installed the latest release of django. I want a simple 'hello world' website that will get me up and running quickly. I am already familiar with web frameworks (albeit for different languages) - so I just need a simple 'hello world' example website to help me get going. Ideally, I don't want to mess up with my Apache server settings (as I am still experimenting), so I want to use the lightweight web server that django bundles. I cant seem to find how to do this on the django website though - no doubt someone will post a link and shame me ... So, does anyone know of a link that shows how to get a simple 'hello world' django website up and running with minimal fuss?

• Connection: Keep-Alive and PHP sessions not working

  - by user366667

  We have a VB application that needs to run an specific flow on a PHP page. This application was correctly catching the PHPSESSID cookie and using it for all subsequent requests. However, PHP wasn't able to restore any changes made on $_SESSION variable. The variable was changed, saved, and on the next request it was restored as an empty array. We found out that changing the Connection header from "Keep-Alive" to "Close" fixed the issue. I couldn't find anything on the web saying that PHP sessions shouldn't be restored under Keep-Alive connections. Does anyone know why this was happening? PS: We didn't find anything weird or different on Apache, ModSecurity or PHP configuration settings.

• Behavior of nested finally in Exceptions

  - by kuriouscoder

  Hello: Today at work, I had to review a code snippet that looks similar to this mock example. package test; import java.io.IOException; import org.apache.log4j.Logger; public class ExceptionTester { public static Logger logger = Logger.getLogger(ExceptionTester.class); public void test() throws IOException { new IOException(); } public static void main(String[] args) { ExceptionTester comparator = new ExceptionTester(); try { try { comparator.test(); } finally { System.out.println("Finally 1"); } } catch(IOException ex) { logger.error("Exception happened" ex); // also close opened resources } System.out.println("Exiting out of the program"); } } It's printing the following output.I expected an compile error since the inner try did not have a catch block. Finally 1 Exiting out of the program I do not understand why IOException is caught by the outer catch block. I would appreciate if anyone can explain this, especially by citing stack unwinding process
