Java No JVM or JRE found

[tech189]

Hi!

I'm new to Ubuntu and I thought that Java would be a good thing have. So I tried installing it. (Using Terminal). Then "java -version" worked so I thought I'd better try Minecraft. It didn't work. Grr. Came up with this error message:

No JVM could be found on your system. Please define EXE4J_JAVA_HOME to point to an installed 32-bit JDK or JRE or download JRE from www.java.com (http://www.java.com).

Then I tried a Java applet: http://mainline.brynmawr.edu/Courses/cs110/spring2002/Applets/Smiley/Smiley.html. And guess what? It works.

What do I do?

Thanks. I'll try and reinstall it now using the info on that page.

EDIT: Do you need to install jre 6 and jre 7 or just one of them?

I installed it from that website and it still doesn't work...

What is the output of

java -version now?

When I do java -version, I get :

java version "1.7.0_12-ea"
Java(TM) SE Runtime Environment (build 1.7.0_12-ea-b05)
Java HotSpot(TM) Client VM (build 24.0-b26, mixed mode)
