Hi,

The application works fine in Jboss 4.3.When migrating the application from Jboss 4.3 to Jboss 6,I am getting the below exception
I have added in web.xml and renamed persistence.xml to some other name.Still the below error is not resolved.

    Thanks
     
    It is sorta covered in the JavaRanch Style Guide.
