Exception Handling with

[Bruce Perryman <bp...@yahoo.com>]

Hello,

How would I catch several errors of type processing
exception?

What I want to do is catch when the session
transformer fails, and when the sql transformer fails.

Is there a place in the documentation that describes
the error codes? If so, I think I can use the
XPathException Selector. Right now, it appears that
all I can catch is the processing exception or the
java sql exception.

Thanks.

The default ExceptionSelector can indeed only differ the handling based 
on the Exception class while the XPathExceptionSelector accepts an 
additional xpath expression.

 From what I read at 
http://marc.theaimsgroup.com/?t=104970559200005&r=1&w=4 (I only found 
that) is that the XPath is evaluated in the context of the exception 
using JXPath. This means if you have an expression "errorcode = 10" you 
would need in your exception a method getErrorcode() - that's how JXPath 
works.

Hope this is correct and helps - otherwise I had to look into the code :)
