If I read the question correctly, you are trying to find out the location of the default JVM and how to change it. If this is correct, the answer depends on your operating system. Please add this information, and try to make the question clearer and more specific. — Zoe

To find out current JVM, run "java -version", or "java", or "java --help", etc. The first one will usually output version information. If you want to know the exact location of the java executable that you are using, then it's dependent on your OS. On linux, you could use the whereis program. i.e. "whereis java"
To switch VMs, you specify a different path. "java" is nothing more than an executable program. So either set your OS's environment path, or reference the path absolutely. i.e. "c:\MyJavaInstall\jre\java.exe -jar test.jar".

If this doesn't help you, then you need to elaborate on your question.
