[jdom-interest] SAXBuilder issues

[Krishnan Anantheswaran]

Hi,

I have a utility class that uses a SAXBuilder to build
a JDOM tree. This works fine. I have a JUnit test case
for it and this works fine thru command line "ant" as
well.

Now when I try to execute the ant task from the
NetBeans IDE, I get an error in building with the root
cause as a class cast exception.

I changed the utility class to use a DOMBuilder
instead of a SAXBuilder and everything works from all
places. 

My suspicion is that there is some classloader issue
but for the life of me I'm not able to get it to work
with the SAXBuilder. Any pointers?

I'm using the latest JDOM sources from CVS. Stack
trace follows.

Regards,
Krishnan
