L2J Server

Hi i m trying to compile server ( core ) but i always get this message :

BUILD FAILED
D:\WorkSpace\L2_GameServer\L2_GameServer\build.xml:77: Unable to find a javac compiler;
com.sun.tools.javac.Main is not on the classpath.
Perhaps JAVA_HOME does not point to the JDK.
It is currently set to "C:\Program Files\Java\jre1.6.0_06"

Pls help =)

You need to install jdk, not only jre.

Thanks =) compile successfull .. but i got one more question because i m newbie in eclipse ...
If i closed program .. how to open project ? should i enter the link of SVN repository again ?

it should reopen automatically...
create a workspace and check out svn to it, that way it'll stay on opening

I can see only Build.xml opened ( text inside of that ) but i cant see files in navigator =\
