My java has flaws

Hello,
I can't get my control panel to open my java control panel. I've uninstalled java, then downloaded it again, but to no avail. Can anybody help?

How I found this flaw was I was on E-bay trying to leave feedback on an item I recently purchased. My own feedback rating is 100%, so my ability through E-bay to leave feedback has not been compromised.

The problem is in my computer, what process.exe needs to run in order for my java program to function correctly? I have so many java files loaded, should I delete them all and start from scratch?

I thank you in advance, my prospective hero

OK. One simple little download and voila! Firefox web browser!
