我正在尝试从部署在 WAS (8.5) 实例上的 EAR 调用 RES 服务器 (v 7.1)。我能够从独立程序调用规则服务器并且它的工作没有任何问题。

但是我的主要问题是从部署在其他 WAS 实例上的另一个 EAR 远程调用部署在 RES 服务器上的 EJB。在这种情况下，我们无法远程查找 EJB。

根据下面的线程，我们应该绕过 EJB3 IlrSessionFactoryAPI 并应该使用 Java EJB API 直接查找规则会话。

IBM 的建议是使用标准 java api 进行 ejb 查找或升级到 Rule Server 7.5（最新的 8.x）。

               IlrStatelessSession session=null;

               try {

                         sessionFactory = JRulesInvoker.getFactory();

                                  }
                         }

检查SystemOut.logRES 服务器的 EJB 的绑定名称是什么，因为看起来那里没有ilog.rules.res.session.impl.ejb3.IlrStatelessSessionRemote。此外，如果您在同一主机上使用相同名称有两台服务器，例如server1，您可能会遇到互操作性问题并且需要将 JVM 属性设置com.ibm.websphere.orb.uniqueServerName为true. 有关更多详细信息，请查看以下页面应用程序访问问题
