Question

Hi I have below pseudo code with throws an exception like this

throw new MyException("Bad thing happened","com.stuff.errorCode");

where MyException extends Exception class. Below is how I am handling the exception

 ActionMessages errors = new ActionMessages();
if(ex.getErrorCode() != null && !"".equals(ex.getErrorCode()))
error = new ActionMessage(ex.getErrorCode()); // com.stuff.errorCode is the errorCode
else
error = new ActionMessage(ex.getMessage()); //"Bad thing happened" is error message
errors.add(ActionMessages.GLOBAL_MESSAGE, error);
//errors.add(Globals.MESSAGE_KEY, error );
saveErrors( requ, errors );
return (mapping.findForward(nextScreen));

Now on the user screen the message appears as

???en_US.Bad thing happened???

I am using Struts 1.2.4 and I am looking into the source code of it, but any pointer will be greatly appreciated.

To avoid ActionMessage trying to interpret your literal message as a key use this constructor:

error = new ActionMessage(ex.getMessage(), false);

The boolean parameter specifies if the String parameter will be interpreted as a code to be looked up (true) or as a literal message (false).
