I have an issue now.  I added some libraries using the sharedlib  
gbean.

However, one of my classes that is in one of these libraries has a  
dependency of the jasper-jdt compiler in tomcat.  I know that this  
is a module which I can reference, but I’m not sure how.

Do I put a dependency tag in the gbean definition?   I tried this  
and this didn’t seem to work.



From you previous post it looks like you added a dependency to the  
shared lib configuration rather than adding a shared lib gbean to  
your plan.  There's no way to affect the parent classloaders of the  
shared lib configuration, so you won't be able to get the jasper  
compiler into that classloader.



However if you add a shared llib gbean to your plan then you can  
get the jasper stuff into your classloader by also adding a  
dependency on the jasper config.  If you are really sure you will  
never need a jsp in your app you can try using a dependency on the  
jasper jar but you are more likely to avoid problems if you add a  
dependency on the jasper configuration.
