We are trying to upgrade our j2ee application from Jboss 3.2.4 to Jboss 4.0.3SP1. The application is using EJB2.0 and all the incontainer testcases are passing on Jboss3.2.4. When i deploy the same ear file on 4.0.3 and try to run the testcases, it automatically shuts down my jboss and i get a socket connection error on server log.
com.ibm.db2.jcc.b.DisconnectException: A communication error has been detected. Communication protocol being used: Reply.fill(). Communication API being used: InputStream.read(). Location where the error was detected: Connection reset. Communication function detecting the error: *. Protocol specific error codes(s) TCP/IP SOCKETS
Could any one pls tell me what setting could be wrong? I am in desperate need to finish this upgrade. Help me
