[jdom-interest] SAXBuilder bug::build(URL or Reader) (part 2)

[Emmanuel Gilmont]

Hi all,

I tested the solution provided by Bill Woodward but it doesn't work and 
I don't know why.

I give a sample code and my xml file here after.

What is strange is that I can read the file when on disk but not trough 
a url, nor in a jar file nor from a website.

I think I will revert to beta 8 version until it's corrected. Except if 
someone has a solution :)

Thanks for all,
Emmanuel
