Forgot password for J2EE-engine-What todo?

Hello,

my problem: I installed the WAS 6.40 incl Netweaver-Studio a few month before. In the meantime i didn't use it anymore, so I forgot my password. Now I have to reuse Netweaver-Studio. I tried to deploy a test-webdynpro-app, but I have to input username and password.

Is it possible to set the Password back, or to find out what it ist, without reinstalling WAS/Developer-Studio?

thanks, chris
