java resource management

[Net Llama!]

Greetings,
I've got a question for the java experts.  I've got a java app running in
j2ee (that i did NOT write).  Are there any good tools for doing resource
management, such as detecting memory leaks, or memory usage optimzation?
Basically I'm trying to determine if this java app can be optimized at
all, or how wasteful it is with resources.

thanks
