Re: Taglib Import: xml Validation Errors with

Thanks guys for the fast replies,

setting the <!DOCTYPE > value in web.xml helped to solve the
validation error for web.xml at least.

I am a bit spoiled by the spring injector pattern and thought
there might be an easy way to inject my own TaglLibFactory that
I overlooked so far, but compiling my own version is a good
option too.


Thanks for the nice work

Michael
