eclipse 调试ejb出错,大侠们帮看看,急死了!!

摘要: eclipse 调试ejb出错,大侠们帮看看,急死了!!

我的eclipse 3.1 myeclipse 4.0 jdk1.4.2 jboss3.2.3
代码是: Hashtable env = new Hashtable();
env.put(Context.INITIAL_CONTEXT_FACTORY,"org.jnp.interfaces.NamingContextFactory");
env.put(Context.PROVIDER_URL,"jnp://localhost:1099");
env.put(Context.URL_PKG_PREFIXES,"org.jboss.naming:org.jnp.interfaces");
initialContext = new javax.naming.InitialContext(env);
Object objRef = initialContext
.lookup("ejb/Trader");
traderhome = (TraderHome)javax.rmi.PortableRemoteObject.narrow(
objRef, TraderHome.class);
trader = traderhome.create();
System.out.println(trader.getHello("qingsong"));

报出以下错误:
javax.naming.CommunicationException [Root exception is java.io.InvalidClassException: org.jboss.proxy.ejb.GenericEJBInterceptor; local class incompatible: stream classdesc serialVe

是不是jdk有问题啊?请帮忙

---

Object objRef = initialContext.lookup("ejb/Trader");
－－－－－

这句话错了

---

对啊,我刚才检测了一下,就是这行出错了,但我不知道怎么回事?
我的ejb_jar.xml是:

<![CDATA[Description for Trader]]>
Name for Trader

Trader

com.interfaces.TraderHome
com.interfaces.Trader
com.ejb.TraderSession
Stateless
<transaction-type>Container</transaction-type>
jboss.xml 是:


Trader
ejb/Trader





我用
Object objRef = initialContext.lookup("ejb/Trader"); 这个名字有问题么?请再赐教

---

是不是我的jboss版本或者jdk不兼容啊 ,郁闷中

---

自己再顶
