ejb-3.0 customized exception

My ejb3 application running on JBOSS6 already has a customized Exception handler "Ejbexception.java" which extends Exception class

I want to use the same to trap Exceptions with some number and send back the same to the Client Code for handling gentel message .

ex:

try{
     .....
}catch(SQLException ex){
   throw new EjbException("1001");
}

Now HOWto get the "1001" on the Client Code ?????

thx in advance karthi开发者_JAVA百科k

Did you write this Ejbexception class yourself? If so, that's a poor choice of name, because there's already a javax.ejb.EJBException in the library. However, it will work: when you throw it, the container will transport it to the client, who can then catch it. The string you inserted will be available from the exception's getMessage() method, just like normal.

If you're actually throwing a javax.ejb.EJBException here, then things are slightly different. That exception is aimed at the container, not the client. I actually don't know how it's made visible to the client. My suggestion would be to switch to using a custom exception, which the container will then pass to the client.
