i faced the same problem like class cast exception earlier.

This is simple classpath error.

Make sure that your client program classpath contains the jbossall-client.jar .

And also open the META-INF of the jbossall-client.jar file and place the jar files which are there in META-INF file in your classpath.

Try this. i'm sure this will work.

when you open the META-INF file, the file contains the code as shown above. Place all the jar files in your classpath(client program classpath). You will get all these jar files in the JBOSS AS folder(lib folder).
