You never want to do that. If you distribute a .jar file set the classpath in its
manifest file. When your Java program runs its too late to set an environment
classpath variable anyway. And you want to stay far far away from any registry.

You are Correct But i want to set Permanantl in Register.
If i am using Runtime it sets for the Java.So it wont set parmanantly in
Windows Classpath(Without AUTOEXEC Batch File)

Perhaps you should create a jar file, use the manifest for it, then play with the code in that jar file to set the permanent things you want to set.
I wouldn't play around with the register though ....

I need only the Progam which sets the classpath in Window Registry.
Can anyone thought me.

You can set an entry in your registry named 'classpath' give it a value that looks
like a classpath value but that still doesn't make it a classpath. The JVM doesn't
look in registries (a Microsoft Windowism) for its classpath. The JVM checks
its command line options, the manifest file in .jars and for an environment
variable named 'classpath'.

If you insist on a permanent classpath value set an environment variable then;
but even that is not a bright idea.

I have Told the Clear Idea.

My Program is to set the classpath in window registry.

No Manifest.MF File,AUTOEXEC.

If that thing is named 'SetEnv' why does it set registry entries and not environment
entries as I expected from the name of it?

A very good point. Anything needed to be done in the registry can be done with the regedit command line utility anyway. The best way to do this is to create a .reg file with your registry keys, and use regedit to import the data.

This entire thread is beyond me: the OP insists on putting a classpath value
in the registry (which is useless, because the JVM doesn't even look in registries).
Now the OP seems to be happy with using environment variables (where the JVM
does look indeed, but still it's a bad idea to put your classpath int there).

Oh well ...
