Problem accessing JBoss from Tomcat 4.1
Hi all
I have basic stateless EJB on Jboss when access these EJB from java stand alone application it works fine. However I have problem when I try to access from servlet on tomcat. I think the problem is on lookup. please help.
this is servlet code
Hashtable env = new Hashtable();
//byte[] bt = {10, 142, 50, 124};
env.put( Context.INITIAL_CONTEXT_FACTORY , "org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL , "10.142.50.61:1099");
env.put("java.namig.factory.url.pkgs" , "org.jboss.naming:org.jnp.interfaces");
try
{
Context ctx = new InitialContext( env );
Object ob = ctx.lookup("jnp://localhost:1099/FirstEjbBean");
FirstEjbHome home = (FirstEjbHome)PortableRemoteObject.narrow( ob , FirstEjbHome.class );
ejb = home.create();
System.out.println( ejb.sayHello() );
ejb.remove();
}
catch( Exception e )
{
e.printStackTrace();
}
this is EJB References in tomcat web.xml
<ejb-ref>
First Ejb
<ejb-ref-name>FirstEjbBean</ejb-ref-name>
<ejb-ref-type>Session</ejb-ref-type>
FirstEjbHome
FirstEjb
</ejb-ref>
this is server out put
