EJB Invocation failed on component by java.security.AccessControlException
提问by saravanakumar
I have a method in EJB Bean
我在 EJB Bean 中有一个方法
@Override
public void checkReqPermission(List<String> req, MyContext context)
throws AccessControlException, Exception
{
if(notAllowed)
throw new AccessControlException("Unauthorized Access : User is
not permitted to execute command(s)");
}else{
...}
In the other side I need to catch this ACEfor further statement execution.
在另一边，我需要捕获这个ACE以进一步执行语句。
When I call this method what does happens? I have lot of exception traces in server.log
当我调用这个方法时会发生什么？我在 server.log 中有很多异常跟踪

I dont print this exception trace any where.
我不会在任何地方打印此异常跟踪。
What does it means? Does indicate access for that method is not allowed or my custom exception?
这是什么意思？是否表示不允许访问该方法或我的自定义异常？
If it is access not allowed for that method means how can I use this ACE? or it is my custom exception means How can I block this exception trace in server log?
如果该方法不允许访问意味着我如何使用此ACE？或者它是我的自定义异常意味着如何在服务器日志中阻止此异常跟踪？
Thanks in advance:).

The messages you see in your log is because java.security.AccessControlExceptionis an unchecked exception (it is a RuntimeException).
When a java.lang.RuntimeExceptionis thrown from the ejb method, the container will
您在日志中看到的消息是因为java.security.AccessControlException是一个未经检查的异常（它是一个 RuntimeException）。当java.lang.RuntimeExceptionejb 方法抛出a 时，容器将
- roll back the transaction
- discard the EJB Bean instance
- Throw the RuntimeExceptionwrapped by
javax.ejb.EJBExceptionto the client.
- 回滚事务
- 丢弃 EJB Bean 实例
- 将包装的RuntimeException抛出
javax.ejb.EJBException到客户端。
In JBoss every EJBExceptionis logged.
在 JBoss 中，每个EJBException 都会被记录。
When you know what kind of exceptions you expect in your client layer, you have to unroll the EJBExceptionto dig into the real reason, and show it to the user if it's meaningful to her. These kind of exceptions would be specialized runtime exceptions you defined (let's say AccessControlExceptionextends RuntimeException).
当您知道您期望在您的客户端层出现什么样的异常时，您必须展开EJBException以挖掘真正的原因，如果它对用户有意义，则将其展示给用户。这些类型的异常将是您定义的专门的运行时异常（假设 AccessControlException扩展了RuntimeException）。
Digging into the real reason is a simple method:
挖掘真正的原因是一个简单的方法：
Throwable unrollException(Throwable exception, Class<? extends Throwable> expected){
while(exception != null && exception != exception.getCause()){
if(expected.isInstance(exception)){
return exception;
}
exception = exception.getCause();
}
return null;
}
In other case, when a java.lang.Exceptionis thrown from the EJB method, you obviously have to declare it in the method's signature with the throws keyword. the container will:
在其他情况下，当java.lang.Exception从 EJB 方法抛出a 时，您显然必须在方法的签名中使用 throws 关键字声明它。容器将：
- the transaction gets commited
- the exception is rethrown to the client.
- 事务被提交
- 异常被重新抛出给客户端。
In EJB terms a checked exception is an ApplicationException. The name indicates that this exception means a problem, the application developer is aware of.
在 EJB 术语中，已检查异常是ApplicationException。这个名字表明这个异常意味着一个问题，应用程序开发人员是知道的。
