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。看起来它连接正常，但实际方法调用有错误。

这是 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);

下面是计算名称的方法：

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：

可能是因为客户端中使用了 jar 文件。看看这个： https ://community.jboss.org/thread/227862

我找到了解决方案，将这一行添加到我的客户端代码中：

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

没有可用于处理的 EJB 接收器
