ejb-3.0 - 从 JBoss AS 7.1.1 上的 Servlet 调用部署在 GlassFish 3.1 上的 EJB 3

Question

我有一个简单的 session EJB(3.0 规范)部署在带有远程接口(interface)的 GlassFish 3.1 上。这是显示部署的日志片段:

INFO: Portable JNDI names for EJB RandomNumber2Bean : [java:global/RandomNumberEJB/RandomNumber2Bean, java:global/RandomNumberEJB/RandomNumber2Bean!beans.RandomNumber2]
INFO: Glassfish-specific (Non-portable) JNDI names for EJB RandomNumber2Bean : [RandomNumber2, RandomNumber2#beans.RandomNumber2]

我试图从部署在同一台机器上的 JBoss AS 7.1.1 实例上的 Servlet 调用它。这是来自 servlet 的相关代码:

Properties props = new Properties();
props.setProperty("java.naming.factory.initial", "com.sun.enterprise.naming.impl.SerialInitContextFactory");
props.setProperty("java.naming.factory.url.pkgs", "com.sun.enterprise.naming");
props.setProperty("java.naming.factory.state", "com.sun.corba.ee.impl.presentation.rmi.JNDIStateFactoryImpl");
InitialContext initialContext = new javax.naming.InitialContext(props);
RandomNumber2 randomNumber2 = (RandomNumber2) initialContext.lookup("RandomNumber2");

但是，每当我尝试从 servlet 获取 InitialContext 以查找 bean 时，我都会收到以下错误:

javax.naming.NamingException: JBAS011843: Failed instantiate InitialContextFactory com.sun.enterprise.naming.SerialInitContextFactory from classloader ModuleClassLoader for Module "deployment.RandomNumberTesterGlassfish.war:main" from Service Module Loader

我已将来自 GlassFish 的客户端 jar appserv-rt.jar 和 gf-client.jar 添加到客户端 Servlet 应用程序的构建路径(我正在使用 Eclipse Juno 部署它)和 %JBOSS_HOME%\standalone\lib\ext 目录。

我在网上找不到任何提到从 JBoss AS 7.1.1 调用部署在 GlassFish 3.1 上的 EJB 的内容。在这一点上我完全不知所措。我能够使用独立客户端调用部署在 GlassFish 上的 EJB，并且能够从独立客户端和 GlassFish 调用部署在 JBoss 上的相同 EJB。

它写在日志中:“Glassfish 特定的(不可移植的)JNDI 名称”。所以，它可能不适用于 JBoss。试试这个:

RandomNumber2 randomNumber2 = (RandomNumber2) initialContext.lookup("java:global/RandomNumberEJB/RandomNumber2Bean");
