Hi there,

how would i calculate how much stack or heap memory my application needs to start with, are there any profilers tools that can help calculate this ?

Thanks

No one can tell you how much memory your application will require, but you can use jvisualvm tool to monitor the heap memory usage by your application.
after java 1.6.13, jvisualvm is distributed with java SDK.

A load test with with the load expected in production along with monitoring using VisualVM or similar tools will give you idea about memory requirement of your application.
