你好，banq，请教一个EJB

你好，banq，你能不能把下面的代码给我讲讲是什么意思？
Properties properties = new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,
"weblogic.jndi.WLInitialContextFactory");
properties.setProperty(Context.PROVIDER_URL, "t3://localhost:7001");

Context context;
context = new InitialContext(properties);
HelloWorldHome hwh = (HelloWorldHome) context.lookup("ejb/HelloWorld");
HelloWorld hw = hwh.create();
