• Continuations in Java

  - by nobeh

  I am looking for recent work presenting continuations in Java. I have come across the same question here but it dates back for a year or two. There is some work such as JavaFlow by Apache, RIFE Continuations (that I cannot download for any reason now). Also there is a blog post mentioning the support in JDK but it seems that the support will span to Java 8. I also reckon that continuations are also introduced in recent Scala versions. I am looking for implementations in Java presenting the continuations concept. And, I am not looking for the works that present continuation-passing-style (CSP). I'd be thankful for any other work you might know.

• Anyone Using the Abyss Web Server

  - by infocyde

  Just curious to see if anyone is using the Abyss Web Server for any projects. http://www.aprelium.com/ I've checked it out a few times, had it running a few ASP.Net demo sites, but haven't gotten to far with it. I like the ease of use, but I'm thinking both IIS and Apache out class Abyss for the most part. Has anyone used it? If so, what is your experience? I ask because I'm tempted to use if for some projects, but if it isn't worth the investment I probably won't. Thanks for your time.

• Java escape HTML - string replace slow?

  - by cpf

  Hi StackOverflow, I have a Java application that makes heavy use of a large file, to read, process and give through to SolrEmbeddedServer (http://lucene.apache.org/solr/). One of the functions does basic HTML escaping: private String htmlEscape(String input) { return input.replace("&", "&amp;").replace(">", "&gt;").replace("<", "&lt;") .replace("'", "&apos;").replaceAll("\"", "&quot;"); } While profiling the application, the program spends roughly 58% of the time in this function, a total of 47% in replace, and 11% in replaceAll. Now, is the Java replace that slow, or am I on the right path and should I consider the program efficient enough to have its bottleneck in Java and not in my code? (Or am I replacing wrong?) Thanks in advance!

• space in url; did browser got smarter or server?

  - by Xah Lee

  It looks like today you no longer to have to encode spaces by %20 in your html links or image links. For example, suppose you have this image at ?http://example.com/i/my house.jpg?. Notice the space there. In your html code, you can just do this: <img src="http://example.com/i/my house.jpg" alt="my house"> It work in all current version of browsers. Though, what i'm not sure is that whether the browser encodes it before requesting the url, or a particular server will do the right with with paths with space? (apache)

• CQRS, Commands, Javascript

  - by Tolu

  I have an architecture where a task-based UI passes commands to a service layer. Now, my intention is to implement the UI in javascript, using KendoUI and the service layer, domain layer etc. in .NET. I'm also looking at future mobile implementations of the client that may use say Java rather than Javascript. If I define the commands in .NET, I'd like to know how to use them from my Javascript client so the client can communicate the commands appropriately to service layer. Do I have to use something like Apache Thrift for this i.e. to define the commands at both the client and service layer?

• Enable GD support in PHP

  - by Don

  Hi, I'm trying to install pixelpost on an Apache server on windows. The installer is failing because: Pixelpost will not run if your PHP installation is not compiled with the GD graphics library. I've added the following line to php.ini extension=php_gd2.dll But I still get the same error message. When I run phpinfo() I don't see any reference to GD, so I guess it really isn't installed. I searched for php_gd2.dll and it's in the ext subfolder of my PHP root dir. I know nothing about PHP, so be gentle with me. Thanks, Don

• 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?

• Still not understanding SVN Repositories in eclipse

  - by jax

  I am about to import my project into svn but don't want to stuff it up. My structure is like this: Repositories: /var/svn/client_name1/ /var/svn/client_name2/ Project directories under /var/svn/client_name1/ project1/ trunk/ branches/ tags/ project2/ trunk/ branches/ tags/ My Apache config looks like this: <Location /svn> DAV svn SVNParentPath /var/svn SVNListParentPath on AuthType Basic AuthName "My Repository" AuthUserFile /etc/svnpass Require valid-user AuthzSVNAccessFile /etc/svnauth </Location> Now I can access my svn repository http://mysite.com/svn/client_name1/ however, there are no projects displayed here, just a Revision 0 message (is that correct)? I can connect to the repository in eclipse using the same url. If I want to place an existing project into the repository what url do I use? http://mysite.com/svn/client_name1/project1 OR http://mysite.com/svn/client_name1/project1/trunk

• What are the main reasons against the Windows Registry?

  - by dbemerlin

  If i want to develop a registry-like System for Linux, which Windows Registry design failures should i avoid? Which features would be absolutely necessary? What are the main concerns (security, ease-of-configuration, ...)? I think the Windows Registry was not a bad idea, just the implementation didn't fullfill the promises. A common place for configurations including for example apache config, database config or mail server config wouldn't be a bad idea and might improve maintainability, especially if it has options for (protected) remote access. I once worked on a kernel based solution but stopped because others said that registries are useless (because the windows registry is)... what do you think?

• PHP connection_aborted doesn't work with nginx?

  - by TheOnly92

  I can't seem to get the function connection_aborted to work with nginx. The code I used to test is as follow: <?php ignore_user_abort(true); ob_implicit_flush(); $i = 0; while (!connection_aborted()) { echo $i; $i++; sleep(1); } file_put_contents('test',$i); In Apache, it works correctly, although it delays a little. i.e. When I press stop button on browser when "3", the 'test' file shows "8". That is an acceptable margin, but on nginx, it doesn't seem to output anything to the 'test' file.

• Protect my PHP App

  - by Abs

  Hello all, I have developed an app and its written in PHP (with a bunch of SQL scripts), this app will be used by a few small companies. For them to use it, I will have to install Apache and SQL Server for them. Every method I have thought has fallen short of what I need. I was actually just hoping to use ZendGuard or IonCube but they don't support PHP 5.3.x. Is there a simpler method where I can maybe store a key in the database and make the app run only when it knows its on that server? Maybe create a key based on some random numbers/letters and the machine name, sql server host name and encode/decode this when ever the system is in use? Thanks all for any help or ideas

• 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.

• Java SOAP WSDL 1.1 message sending all the parameters (even future ones)

  - by Eduardo

  I have to communicate with a SOAP Web Service defined in a WSDL 1.1. All the parameters are optional in the WSDL like: <xsd:element name="Submitter" type="xsd:string"/> but if I do not send them I get an error because the parameter was not sent, so instead I have to send an empty string for any parameter I do not intent to send. So instead of not sending the element I have to send: <Submitter></Submitter> The problem is that the WebService publisher does not have any problem adding new parameters at any point in time but I must sent at least an empty string for all the parameters. How may I call this WebService in Java so every time I call the WebService the WSDL is read so that all the parameters are sent having the parameters I care for are actually filled with the data I provide? I am currently using Apache CXF but I am open to anything to solve this problem.

• 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?

• 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

• 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.

• 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.

• 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).

• 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.

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.
