Hi,

if changes described in FAQ didn't help,
i suggest to make change in net.jforum.util.bbcode.BBCodeHandler.parse()
from:



to:


this is useful if you use Xerces/Xalan under Windows OS

Hi Jacek,

Thanks a ton! This tip really helped!!

However, just curious - my configuration worked fine on one m/c, but gave this problem on another. All JARs apparently seemed to be similar. I couldn't quite understand the reason for this exception.

Cheers,
Saurabh

Tomcat 4.1 is pretty old... it's probably a problem with either the JVM version that's running this or just the Tomcat version. It might also be a problem with the version of the Xerces XML libraries not working with older JVM code.

I'd suggest upgrading to modern versions of both the JVM and Tomcat (at least JVM 5.0 and TC 5.5). In theory, Jforum should run on older versions but this hasn't been tested recently.

FWIW, it looks like it's trying to parse a local file name (C:\...) as a URL for some reason.
