How do I run a Java program? (Arachnophilia 5)

[odz]

Yes they do have a windows installer version, but I would like to know how to do this anyways.
I am trying to install Arachnophilia. I unpacked the jar to a folder, then did what their web page says:

Open a command console (Linux: shell console), move to the Arachnophilia program directory, type "java -jar Arachnophilia.jar"

But when I do that it just gives me an error message about files missing.
I do have Java installed BTW.
So how does one run java programs?

It says there is in installer executable..
Do you have JRE from sun's site?

I have the JRE, and I just DL'ed the installer but all that does is put the .jar in my program files directory, a lot of help that is.

That's all it does because a Java installer is just a JAR file. Given that you get errors when you run "java -jar Arachnophilia.jar", you're either executing the command in the wrong directory, your JRE is not installed correctly, or the java binary isn't in your executable path.

In the console, try the command:
java -version

If that works, then the JVM was installed properly and the java command is in your PATH. Otherwise, follow the INSTALLATION and README documents for the Sun Java2 VM.
