Performance test tool for message based j2ee application

[Nazneen Shaikh]

Hi,

I need to do performance testing for a message based j2ee application. my platform is Solaris and am using weblogic8.1(sp3) app server. I have been using the console and monitoring graphs on weblogic console but i guess i need more than that.

Can anyone suggest any good, FREE tools for the same?

Thanking in Advance,
