jboss.xml 
<jboss>   <unauthenticated-principal>nobody</unauthenticated-principal>   <enterprise-beans>
     <entity>
         <ejb-name>Build</ejb-name>
         <jndi-name>BuildBean</jndi-name>
         <local-jndi-name>BuildLocal</local-jndi-name>      </entity>
   </enterprise-beans>   <resource-managers>
   </resource-managers></jboss>

服务器端的布署应该不需要变什么的吧。没用过jboss，但有一个client调用weblogic的例子：以下初始化：
 DealXml xml = new DealXml();
        String topTaisIP = xml.getTopTaisInfo();        Hashtable ht = new Hashtable();
        ht.put(Context.INITIAL_CONTEXT_FACTORY,
                "weblogic.jndi.WLInitialContextFactory");
        ht.put(Context.PROVIDER_URL, "t3://" + topTaisIP);        try {
            ctx = new InitialContext(ht);
            PrefixHome  prefixHome = (PrefixHome) ctx.lookup("PrefixBean");
            Prefix prefix = prefixHome.create();
        } catch (NamingException ex) {
            prefix = null;
            log.sysLog.error(ex.getMessage());
        } catch (RemoteException e) {
            prefix = null;
            log.sysLog.error(e.getMessage());
        } catch (CreateException e) {
            prefix = null;
            log.sysLog.error(e.getMessage());
        }我想jboss上面也大同小异吧:)

Answer 4

哦，忘了说了，DealXml xml = new DealXml();
        String topTaisIP = xml.getTopTaisInfo();是通过一个config.xml文件取服务器为topTais的ip及端口

我想你可以在访问是来找另一台机器的EJB服务器的类的JNDI名字,然后就可以调用了.代码这样:
properties = new Properties();
        properties.put(Context.INITIAL_CONTEXT_FACTORY,
                       "org.jnp.interfaces.NamingContextFactory");
        properties.put(Context.PROVIDER_URL, "另一台机器的IP:8080");
        Context context = new InitialContext(properties);        XXHome jbossHome = (XXHome) context.lookup(
            "XXX");
        XXREMOTE userInfo = jbossHome.create("");注意要把你的另台机器的 XX.JAR包COPY过来呀! 不知道是这个意思吗?
