WURFLHolder wurfl = (WURFLHolder) getServletContext().getAttribute(WURFLHolder.class.getName()); //line 1

WURFLManager manager = wurfl.getWURFLManager();//line 2

Device device = manager.getDeviceForRequest(request);//line 3

we are calling above code but on line 2 server does not give any response. I have put listener entry in web.xml correctly.
web xml entry as below.
<context-param>
<param-name>wurfl</param-name>
<param-value>classpath:/wurfl.zip</param-value>
</context-param>


<listener>
<listener-class>
net.sourceforge.wurfl.core.web.WURFLServletContextListener
</listener-class>
</listener>

Can you tell us where exactly is the wurfl.zip file placed?
Moreover, could you try to upgrade to the latest Java API version (1.4.4.3)?
There should be no difference in terms of initialization, while on the other hand wurfl.zip file retrieval should be more consistent.

I have tried with upgraded version of wurfl i.e. wurfl1.4.4.3 and my wurfl.zip is placed in WEB-INF/classes.

I guess I have the solution, then.

Try to replicate the 1.4.4.3 helloworld configuration: place the wurfl.zip file in the WEB-INF folder, at the same level of the classes folder, instead of inside it
Then copy this in the web.xml file:

Code: Select all

<context-param>
	<param-name>wurfl</param-name>
	<param-value>WEB-INF/wurfl.zip</param-value>
</context-param>
As I wrote in my previous post, 1.4.4.3 should have enhanced wurfl.zip file loading, letting you avoid the classpath:/ constraint.
Let me know if this fix solves your problem.

There was some jar conflict issue in our project. We have rectified these conflicts. Now Project is working fine.

Problem fixed. It was actually a server configuration issue, causing JBoss not to recognize wurfl.zip path.
As usual, as in any Java projects, make sure that you don't have JAR files of older versions of the libraries in forgotten places where the CLASSPATH can still see them.
What we noticed is that sometimes JBoss fails to recognize paths like WEB-INF/<path_to_wurfl.zip>.
Nevertheless, paths like classpath:/<path_to_wurfl.zip>, or absolute paths like file:///<path_to_wurfl.zip> seem to always work.
