小弟在做ejb的一个小例子，部署可以但是在测试的时候出现这样的异常，搞了一天多了，哪个大哥知道的帮帮忙啊
ejbtest.java
public class EJBTest {
/**
* @param args
*/
public static void main(String[] args) {
Properties properties=new Properties();
properties.setProperty(Context.INITIAL_CONTEXT_FACTORY,"weblogic.jndi.WLInitialContextFactory");
properties.setProperty(Context.PROVIDER_URL,"t3://localhost:7001");
Context context;
try
{
context=new InitialContext(properties);
HelloWorldHome hwh=(HelloWorldHome)context.lookup("ejb/HelloWorld");
HelloWorld hw=(HelloWorld) hwh.create();
System.out.println(hw.Hello());
}
catch(Exception ex)
{
ex.printStackTrace();
}
}
}
