Hi

It is in our TODO list a collection of taglibs, and that's the place where I 
see a convergence between Tomcat and OpenJMX. I agree that a "generalized" 
admin app won't be too useable/useful, but the basic building blocks can be 
common.

We haven't progressed on this but I should start working on that soon. I'd 
like to have them in OpenJMX, but if I'm not the main contributor I don't see 
any problems having them in jakarta-taglibs. We can build our admin app out 
of them later
