Change Java.exe to some other name

Question

I have jdk1.6.0 installed on my machine with jre1.6.0
when i am running any application its process is running default java.exe
java.exe in Task Manager.
How to change the java.exe name to java1.exe .

Answer 1

Rename the exe on the disk.
There are utilities in Unix which allow you to change the name a process appears to have. But since you said .exe, I guess you're using Windows.
I've done this very successfully before. I have n batch files as part of a product which start different components of the project, each one does something like this...
if exists ..\jre\bin\blah.exe goto blahexists
copy ..\jre\bin\java.exe ..\jre\bin\blah.exe
:blahexists
..\jre\bin\blah.exe -cp blah blah
In that way, each batch file can dynamically create a new .exe as approprate and the Windows task manager will show you blah.exe (and foo.exe and myserver.exe) instead of java.exe, which means you can kill them! :-)
