i am using suselinux 8.1, want to install j2sdk1.4.2_04 and eclipse,

but since suse linux laready has jre 1.3.1 installed and the JRE_HOME, Java_root enviroment has already been added in PATH, so althrough I added my j2sdk path in PATH, when i type java or javac, it still goes to the usr/lib/java, and eclipse also could not run , so how to modify the enviroment variables including java_root, path instead of adding new ones in.

it seems some linux applications depend on the default java 1.3.1.

and any one knows how to create eclipse run script,

thanks alot
