Exit code=127 when I start Eclipse

Question

I've installed Ubuntu 10.10, Eclipse Juno and Java 1.7.

Firstly, when I tried to start Eclipse, this last one said me that it doesn't exist a java runtime environment on my computer. So, I've created in the Eclipse directory deux others directory(jre/bin) within I put all the files from the bin directory of java.

After, When I started, I had this following errors :

JVM terminated. Exit code=127

Do you have a solution ?

Searching the net, it seems it was already reported:

http://www.linuxquestions.org/questions/linux-software-2/eclipse-juno-start-up-error-127-a-4175418488/

And the solution suggested was:

I figured it out. I installed JDK7 and was under the impression that it would also install JRE with it. Whenever I went to anything that used Java it said it was using 7 so I assumed it must have. I guess the difference between the JDK and the JRE installed caused it to not work
