I am starting using:
catalina.sh start
stopping with
catalina.sh stop
I don't even have a lib directory in my WEB-INF , just my class file :(
Does anyone on this list have any interest in being hired as a consultant?
At this point I have this security issue (which may or may not be a problem)
and a database memory leak that I can not figure out. Database pooling may
be a fix for that but I can not get that working either.
