axis/tomcat find jars

[Frank]

I have been getting some weird results now and again and I was wondering 
if some one could explain to me how when using tomcat with axis want 
libraries will be used?  i.e. does it use your environment variable 
classpath or only what resides in the webapps\axis\WEB-INF\lib directory 
or some combination?

   If just what's in the lib directory how does it know what jar to use 
if for say you have conflicts, i.e. diff filename/versions of the same 
classes in a jar file?


Thanks,

Frank
