调用ejb时,如果客户端和ejb不在同一个jvm,就要设置InitialContext,不同的应用服务器InitialContext写法也不同.
Context.INITIAL_CONTEXT_FACTORY:指定到目录服务的连接工厂
Context.PROVIDER_URL:目录服务提供者URL
//jboss:

Context.URL_PKG_PREFIXES, "org.jboss.naming"
Context.PROVIDER_URL, "localhost:1099"
//weblogic:

Context.PROVIDER_URL, "iiop://127.0.0.1:1050"
Context.INITIAL_CONTEXT_FACTORY, "com.sun.jndi.cosnaming.CNCtxFactory"
Context.PROVIDER_URL, "iiop://127.0.0.1:1050"
//SilverStream:

Context.PROVIDER_URL, "sssw://localhost:80"
//OC4J:
Java代码
Context.INITIAL_CONTEXT_FACTORY, "com.evermind.server.rmi.RMIInitialContextFactory"

Context.PROVIDER_URL, "iiop://localhost:2809"
Borland Enterprise Server JNDI用法
Java代码
Properties props=new Properties();
props.put(Context.PROVIDER_URL,"corbaloc::173.6.7.143:14500/NameService");
props.put("java.naming.factory.initial","com.inprise.j2ee.jndi.CtxFactory");
Context context = new InitialContext(props);
// Context context = new InitialContext();
Object ref = context.lookup("com/borland/examples/j2ee/hello/Hello");
HelloWorldHome home = (HelloWorldHome) javax.rmi.PortableRemoteObject.narrow(ref, HelloWorldHome.class);
hello = home.create();
Properties props=new Properties();
props.put(Context.PROVIDER_URL,"corbaloc::173.6.7.143:14500/NameService");
props.put("java.naming.factory.initial","com.inprise.j2ee.jndi.CtxFactory");
Context context = new InitialContext(props);
// Context context = new InitialContext();
Object ref = context.lookup("com/borland/examples/j2ee/hello/Hello");
HelloWorldHome home = (HelloWorldHome) javax.rmi.PortableRemoteObject.narrow(ref, HelloWorldHome.class);
hello = home.create();
