What jars do you have in web-inf/lib?
One possible solution - remove from web-inf/lib and jars that are already present in server/default/lib. This includes removing log4j.jar.
I have some custom Jar file which I need for my application.
That jars are not present in the server/default/lib.
I also tried it to put all the jars in the server/default/lib directory.
but my application is not able to get that jars.
But same war file i deployed in different app servers where it is working perfectly.
The missing class file is located in the server/default/deploy/console-mgr.sar/web-console.war/applet.jar file. You need to include that jar in your web-inf/lib directory.
Actually, because you need this jar, I suspect that your code is not written correctly because you can lookup the MBean Server without using that class.
