        }
    }

}



and I m using weblogic 8
after deploying and 
runnig the HelloClient



m getting the following Exception
-----------------

javax.naming.AuthenticationException。根异常是java.lang.SecurityException：User：manager，无法进行身份验证.at weblogic.common.internal.RMIBootServiceImpl.authenticate（RMIBootServiceImpl.java:95）在weblogic.common.internal.RMIBootServiceImpl_WLSkel.invoke（未知来源）在weblogic.rmi.internal.BasicServerRef.invoke（BasicServerRef.java:466）在weblogic.rmi.internal.BasicServerRef $ 1.run（BasicServerRef.java:409）在weblogic.security.acl.internal.AuthenticatedSubject.doAs（AuthenticatedSubject.java:353）在weblogic.security.service.SecurityManager.runAs（SecurityManager.java:144）在weblogic.rmi.internal.BasicServerRef.handleRequest（BasicServerRef.java:404）在weblogic.rmi.internal.BasicExecuteRequest.execute（BasicExecuteRequest.java:30）在weblogic.kernel.ExecuteThread.execute（ExecuteThread.java:197）在weblogic.kernel.ExecuteThread.run（ExecuteThread.java:170）

Please tell me the solution for this n thanks in adv.

Answer 1

这可能有以下几个原因：

1） User: manager中不存在Weblogic login realms。在这种情况下，请检查 Weblogic 中的Users/Groups设置。

2）在部署之前或之后，您没有将User: manager映射到部署描述符中定义的任何roles。检查已部署的应用程序，看看User: manager是否映射到任何提供的角色。

3）您的代码引用了错误的角色名称。

例如：

isUserInRole("Manager");

此代码不起作用，因为它不引用部署描述符中定义的任何<role-name>。检查小写，大写，完全字符。因为isUserInRole区分大小写。

注意：请发布执行角色检查的代码，并发布可能的完整错误堆栈跟踪。

EJB2授权相关的简单程序（java.lang.SecurityException：User：manager，无法通过身份验证。）
