Tomcat Memory Usage

[Guest_imported]

Tomcat servlet engine(I think its 3.2) is running on NT box, and we are using it for reports. Memory usage is keep on increasing for each request and never comes down.

I tried investigate with JProbe, but JProbe evaluation copy works only for jdk1.2. Is there any other tools to find the bottle necks for jdk1.1.8?

Is there any other way of finding bottlenecks?

Thank you,

my similar problem was solved when i realized that a memory leak in my jdbc driver was using up all the memory, and i searched for and found an update .
