well, I understand the way tomcat loads its classes and that tomcat can't
expand the classpath after loading the VM (so tomcat would need to know all
contexts *before* the VM is started - but tomcat is written in java, so it
can't do that without the VM ... ;-) )
my problem:
I have many jar-files only needed by *one* context, but I have to put all
that jar-files into the same directory (/lib/apps) - that's not very easy to
maintain!!!
so I thought of writing a kind of classloader, that additionaly loads classes
from jar-files in /webapps/<context>/WEB-INF/lib (but I never did this before
- and I don't know if it's possible!!!)
this classloader is instantiated by the servlet; and all classes that are not
found by the VM-classloader, are loaded using MY classloader ...
any idea???
thanks
any hints appreciated
