I deployed and tested a simple EJB 3.0 program successfully with JBOSS 4.05.
The following code use JNDI lookup works fine.
| Hashtable<String,String> h= new Hashtable<String,String>();
|
h.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
| h.put(Context.URL_PKG_PREFIXES, "org.jboss.naming:org.jnp.interfaces");
| h.put(Context.PROVIDER_URL, "localhost");
|
| InitialContext ctx = new InitialContext(h);
|
| WordReverse wr = (WordReverse) ctx.lookup("/WordReverseBean/remote");
|
| wr.getReversedWorld("test")
|
However, I have problems using EJB annotation. The following code compiles
fine. but run into run-time Exception
Exception in thread "main" java.lang.NullPointerException
It complains that the instance variable wr is NULL. I tried different
attribute values for the EJB annotation without sucsess.
| @EJB(mappedName="jnp://localhost:1099/WordReverseBean/remote")
| //@EJB(beanName="WordReverseBean")
| //@EJB
| private static WordReverse wr;
|
| public static void main(String[] args) throws NamingException{
|
| ...
| wr.getReversedWorld("test")
| ...
|
Could anyone help here?
Thanks!
