Hi all,
did anyone know how to  measure  memory that reside in a session in  JVM environment? what i
mean here is
when I put some object say ResultSet , Vector in session object, it will keep in the memory of JVM
until the
session expired, so when there are too many users in the session, it might crash the JVM,

so, can anyone can suggest me any tools to measure the JVM memory used? thanks in advance.
