Eclipse won't work


Hi!

Since I am new to the whole Linux "experience", and I can't figure out what to do, I'm turning to you!

I recently downloaded Eclipse (Java designing program) and I can't get it to work.

When I go to the /usr/local/eclipse dir and type ./eclipse I get the error message: No Java VM was found after searching the following locations: /usr/local/eclipse/./jre/bin/java 'java' in your current PATH.

echo $PATH gives: /usr//bin:/bin:/usr/bin::/usr/local/bin:/usr/X11R6/bin:/usr/games:/home/jeroen/bin:/usr/local/j2sdk_bn/j2sdk1.4.2/bin:/usr/local/limewire

Before I installed Eclipse, I installed the Java SDK 1.4.2

Did I mess up the PATH somewhere (now that I look at it, it seems kind of messy, or does it?)? Is Eclipse the problem?

Anyway, all help is appreciated!

TIA

BTW: I'm running Mandrake 9.2

Welcome to LQ.

It does sound like you haven't got the correct entry for Java in your PATH. I mistakenly added /usr/java to my path when I should have had /usr/java/j2re1.4.2_01/bin.

If you know where the java executable is then you should be able to run your java programme(s) (presuming it is a .jar file) with /path/to/java -jar filename.jar

Hope this helps.

Hi There...try doing the following:
1) Add the /java/bin directory to your path: PATH=othervalues:/usr/java/bin
2) Export the path: export PATH
3) Set the java_home variable. I.E. JAVA_HOME=/usr/java/ (Make sure you specify the root of the java installation folder.)
4) Export JAVA_HOME
5) Type 'java' in the console, and if it loads, everyting will be okay...Then go and run eclipse.....This should work....

Cheers

I finally got it to work!

I exported the wrong PATH (/usr/local/j2sdk_bn/j2sdk1.4.2/bin) when I should have been exporting /usr/local/j2re1.4.2_03/bin!

Thanks for the help

You will always be able to know which java you are pathing to with this command:

$ which java
