【问题描述】：

我已经搜索了网络和旧问题，但没有解决我问题的答案。 全新安装 JBoss 7 1.1 final，我正在尝试使用 JNDI 调用 EJB。看起来连接正常，但实际调用方法时出错。

这里是 Java JNDI 代码：

InitialContext context = null;
Hashtable env = new Hashtable();
String ejbUrl = TestEJBClient.calculateJbossEjbJndiName ( "TestEJB" , "" , "" , TestEJB.class.getSimpleName ( ) , TestEJBRemote.class.getName ( ) , false );
env.put("jboss.naming.client.ejb.context", true);
env.put(Context.URL_PKG_PREFIXES, "org.jboss.ejb.client.naming" );
env.put(Context.INITIAL_CONTEXT_FACTORY, "org.jboss.naming.remote.client.InitialContextFactory");
env.put(Context.PROVIDER_URL, "remote://localhost:4447");
env.put(Context.SECURITY_PRINCIPAL, "jboss");
env.put(Context.SECURITY_CREDENTIALS, "jboss1");
context = new InitialContext(env);
TestEJBRemote ejbRemote = (TestEJBRemote) context.lookup(ejbUrl);
Customer rtn = ejbRemote.getCustomerByAccountNumber(accountNumber);

这里是计算名字的方法：

public static String calculateJbossEjbJndiName(String appName , String moduleName , String distinctName , String beanName , String viewClassName, boolean stateful)

     String rtn = "ejb:"+appName+"/"+moduleName+"/"+distinctName+"/"+beanName+"!"+viewClassName;
     if (stateful)
     
          rtn = rtn + "?stateful";
     
     return rtn;

这是运行的日志：

【问题讨论】：

我想我是通过在 ejb 文件名之后添加 jar 文件名来完成这项工作的，必须先解决调用期间的错误，然后才能验证

检查这个：***.com/questions/11975396/…

【参考方案1】：

可能是因为客户端使用了 jar 文件。看一下这个 ： https://community.jboss.org/thread/227862

【参考方案2】：

我找到了解决办法，就是在我的客户端代码中加入这一行：

jndiProperties.put("jboss.naming.client.ejb.context", "true");

No EJB receiver available for handling
