问题描述

我是Java EJB 3.0的新手。可以从桌面应用程序客户端调用（会话）bean—部署在JBoss—

I am new in Java EJB 3.0. It is possible to call a (session) bean—deployed on JBoss—from a desktop application client?

推荐答案

是的，你可以。这里有一些细节（引用EJB2，但对于远程客户端，它与EJB3相同）： http://www.theserverside.com/discussions/thread.tss?thread_id=9197

Yes you can. Some specifics are here (references EJB2 but it the same for EJB3 when it comes to remote clients): http://www.theserverside.com/discussions/thread.tss?thread_id=9197

释义：

Hashtable env = new Hashtable();
env.put("java.naming.factory.initial", "org.jnp.interfaces.NamingContextFactory");
env.put("java.naming.provider.url", "jnp://localhost:1099");
env.put("java.naming.factory.url.pkgs", "org.jboss.naming:org.jnp.interfaces");
Context ctx = new InitialContext(env); 
// name is whatever JNDI name you gave it 
Object o = ctx.lookup("home name"); 
EJBHome ejbHome = (EJBHome) PortableRemoteObject.narrow(o,EJBHome.class); 
// This is userID should be the one passed. 
EJB ejb = ejbHome.create(..);
