RE: how to handle unknown exceptions/errors

[Brian McSweeney]

I dug a bit deeper into this and found that in struts-1.1 
there's a global-exceptions facility in struts-config.xml 
Where you can declaratively handle exceptions for example:

<global-exceptions> 
   <exception key="system.error" 
        type="java.lang.Exception"
      path="/appError.jsp"/>
</global-exceptions>


But I'm still a bit confused. Would people recommend using 
this?

How do you folks handle system exceptions?

Cheers,
Brian

Subject: how to handle unknown exceptions/errors

Hi all,
 
Is there a standard way to handle all unknown exceptions in 
Struts?
 
For example in my Action classes I normally 
Catch specific exceptions and forward to specific error pages.
 
But for all other exceptions should I just forward to a global 
Errors page?
 
Eg:
 
In my struts action
 
 
public class MyAction extends BaseAction
{
    //~ Methods
----------------------------------------------------------------
 
    protected ActionForward doExecute( ActionMapping       mapping,
                                       ActionForm          form,
                                       HttpServletRequest  request,
                                       HttpServletResponse response )
    {        
      // do stuff
 
      catch(SpecificException se){
            forward to specific error page
}
 
      catch(Exception e){
            forward to global error page
}
 
    }
}
 
Is this how it generally works?
 
Cheers,
Brian
