TR: [opencms-dev] Help ! Resource loader error ...

Constants is a class.
I'm simply putting it into WEB-INF/classes and trying to use it into my JSP.
With no success.
If I move my JSP to another webapp than OpenCMS and copy my class, the JSP
works... It seems OpenCMS converts something that disallow my class to be
properly loaded ...
Because of this error, I never managed to use classes into OpenCMS ...
Any clue ?
