Client calling a service implemented by an EJB? (my code in here. ..)

[Tiago Fernandes Thomaz <ti...@optimus.pt>]

Please tell me what can I do to get this running?

As you can see I'm calling a service that is implemented in a bean hosted by
JBOSS. Can I do the SOAP request like this? What am I doing wrong?
