Thanks for help in advance,

The application(ear) is deployed successfully in jboss, when we do load test(on sockets and threads used in the application) on the application we are getting the following exception

venugopalp,

The best place to discuss such questions is the "Installation & Deployment" forum here http://www.jboss.com/index.html?module=bb&op=viewforum&f=61. Please open a new thread there with more details about your application, the JBoss and Java version you are using and the operating system.

when we do load test(on sockets and threads used in the application) on the application we are getting the following exception

java.net.SocketException: Too many open files
at java.net.PlainSocketImpl.socketAccept(Native Method)

Just a guess - you may not be closing the opened sockets in your application. If you more related question open a new thread as mentioned above.
