Simple SessionBean --- ClassCastException
Hi!
I am using the JBossIDE 1.5.1 and JBossAS 4.04.
I have coded a simple SessionBean and a Servlet. Please take a look at the code below.
The deployment of the ejb.jar seems to be ok: [ProxyFactory] Bound EJB Home 'Hello' to jndi 'ejb/Hello'
When i am accessing the servlet i am getting an java.lang.ClassCastException in the servlet at line marked with ">>>>>>>".
I have spent 4 hour and can not find a mistake.
Please take a look at my code an tell me what is wrong.
Thanks
Bronks
