Re: Taglib Import: xml Validation Errors with

Sure, try turning validation off and see whether it fixes your  
problem. It is really easy to rebuild freemarker.jar, you just need to  
issue "ant jar" -- build.xml will download all required dependencies  
from the Internet automatically.

It is indeed a curious problem that you're getting these errors. I  
guess the JAXP "setValidation(true)" would mandate DTD validation, and  
it doesn't consider XML Schema validation? Just a guess...
