Is it possible to create two JVMs on one machine?

Hello,

Is it possible to create two JVMs on one machine?

 

[sedj]

Yes. Just start two instances of the java executable.

Cool, and can I decide at which one of these instances my application will work?

 

[sedj]

Yes.

The same way you decide when starting one JVM.

When I start one JVM I use java MyClass in order to run my application, how will do it when two JVMs are running? I am still using the same java.exe from the same folder.
I know I miss something here I just don't know what...

Do you want to run two Java-programs in their own JVM - one Java-Version, but two instances,
- or -
run two different JVMs?

The first case is trivial.
The second needs you to install the second version in a differnet location.
Only one of them is the first found in the path, so you have to call the whole path to second:

java.exe Foo
C:\Programs\J2SDK-1.4\bin\java.exe Foo
