Thank you for your reply...

i would like to know what are the thing i have to add in it and where it is located in deploy folder (the file jboss-web.xml)

as we i have four different files in jboss 5.0 under deploy folder

1. in jmx-console.war/WEB-INF

2. in http-invoker.sar/WEB-INF

3. in jbossws.sar/WEB-INF

4. in management/console...../.../WEB-INF

or i have to create my own for the application and where it should be then??

Thanks once again for your reply 

But after changing the variable of security role in web.xml file, it is giving as new error which is now related to some context parameter and now i have to use any context parameter file as we have used in tomcat server called as context.xml file. The error is given below:

Looking for more pointers in this regards....

Thanks for your reply

I have been using IDE eclipse for the development purpose and it does not give any error of that kind in it.

but when the version of Web-app Document type is changed it is giving errors and how to find which version to use and which not to use ?

Is there any specific version for a particular type or a common version while developing it??

Thank you for your reply

As i said earlier that i am using eclipse and i have the WebToolsPlatform plugin in it.
