I've always wondered how to use the JVM without downloading the Sun JDK.
Once I download a suitable JVM, how is it used?
Perhaps you guys can direct me to a good freely downloadable JVM and, as you are familiar with it, provide a few instructions on how to use it (if it doesn't come with instructions). Perhaps, say, I have just a single class to run, just to demonstrate how to use it.
If you don't want the full JDK, you can download the just the JRE (essentially the JVM plus class libraries) from Sun (or from IBM for some platforms).
If you're specifically interested in a non-Sun JVM, check out Kaffe or SableVM (both of which can make use of the GNU Classpath libraries, if you need more than just the JVM). They're both non-trivial to install, but plenty of information is available from their respective web sites.
