We are using J2EE 1.4, servlet version 1.4 and EJB version 2.1,  We are developing modules using  netbeans 5 or 6.9.1. When we deploy the ear file in jboss 6 its working fine. when we deploy the same ear file in jboss 7, we are getting exception. Is there any specific deployment configuration for jboss 7, Kindly help me to deploy my existing server files in jboss 7.  what needs to be done to deploy my existing server files in jboss 7. Is there any build tool for it.

I have placed the supporting(dependent) lib files for the ear in JBOSS_HOME\standalone\lib\ext\ path.

I have attached the error log and my server file.
