How to access system registry through java program

Friends

I have to access System registry of Windows 2000 by Java program. I don't know how to access the registry by using java code. Please help me. Else

I want to create a setup file for my application. before setup my application i have to check whether the system has JVM or not. If its not then i have to install JVM first and then my application. so i need to access system registry. please give me a solution for this.

Thanks in advance

>call native method can visit registry.>maybe you can use "installshield" to create a install package,installshield may provide some function to check user's java VM

This doesn't exactly solve your problem, but check out the Preferences class. On Windows, it uses the Registry as the backing store.

erm... cant the instalation application (you said written in java) detect that it has the jvm, simpy by the fach that it can run at all?

I can suggest MS MSI Installer cause it is open source (hehe), and just bundled your application.. or i can suggest running batch file... this way you can invoke it on java app
