Hi evryone, I'm really getting mad with this in need a little of help.

I have an Enterprise Service Buss (ESB), a Server connected and a Java web site in this server, I have some Alerts defined in the ESB about the threads and the memory and I need to test if the alerts works properly.

I have tried using JMeter, loadUI and LOIC to creat and simulate users loging into the website and create a load testing but it doesn't matter how many connections do I use I can make the server create more threads or consume more memory the web site gets a little slower and thats all. But I MUST test this Alerts so I need an application in a JSP web page which when I do a get it uses a lot of JVM resourses, do anyone know how to do something of this sort ?

I would really appritiate some help.
thanks
