New to Java

I tried to find the best possible place to post this and after spending about 20 minutes searching for an appropriate forum starting from java.com I ended up here. So forgive me if the is a wrong place and if there?s a more appropriate place for my question, please provide a pointer to it.

I don't know much about java and what it does but as the title says when I open the Task manager there are two java.exe processes running at the same time with about 20 000 k each.
One of the processes is coming from:
C:\Program Files\Alias\Maya6.5\docs\jre\bin\java.exe
and the other from:
C:\Program Files\Alias\Maya7.0\docs\jre\bin\java.exe
in addition to that a jusched.exe process is also running coming from
C:\Program Files\Java\jre1.5.0_10\bin\jusched.exe

I rarely open the Maya 6.5 and 7 documentations but the two java.exe process are running all the time and I would like to stop them running when I don?t need them but I don?t know how.
I can't end these processes from the Task Manager; they reappear immediately after I end them.

Any help with this is greatly appreciated.
Thank you
