JDK won't work

[Shin_Gouki2501]

I'm still not sure but:
Those "gcj"-stuff really messes up the java experience of many java "newcomers". I hope open jdk will come to ubuntu soon...and that it will work "better".

You are still using the GNU version of the JDK.

In “Window” > “Preferences” > “Installed JREs” you need to “Add” the Sun JDK and set it as the default.

The JDK should be in the "/usr/lib/jvm/" folder.

Thank you.... This worked for me as well

OpenJDK is the default Java on Ubuntu 8.10, and ofcourse it's much better than GNU Java (GCJ).

2 more things to check.

1. Make sure that the "JRE System Library" is setup as a library for your project.

Right click your project "Properties" > "Java build path", libraries lab. You should see "JRE System Library..." if you are setup correctly. If not click "Add library" and add "JRE System Library".

2. Make sure you haven't overridden your workspace complier settings at the project level.

Right click your project "Properties" > "Java Compiler", make sure that "Enable project specific settings" is NOT checked.

Good luck

Thank you so much...

Thank you so much!! Every time I've updated ubuntu I've had to fix this again and have had to just stumble around until I found something that miraculously worked. I'm so glad to have found someone who knows what's going on!

That's just what I was lookin for?

Thanx a lot
