Re: [Java] Development Kit Issues



ok, so i exported the path with
export JAVA_HOME=/home/ahelmy/jdk1.5.0

then i checked which jar, it said
/usr/bin/jar which is a link that points to /usr/java/jdk1.5/bin/jar which is the correct path

so then i remade the file using jar -cf, but the bloody bastard (MANIFEST.mf) still says Created-By: 0.92-gcc

WTF should i do now?

I did some searching and found that java-1.4.2-gcj-compat-devel contains
jar program. You may check if it's installed and remove it.
You can update the PATH as well, if You have exported JAVA_HOME
previously:
export PATH=$PATH:$JAVA_HOME/bin

hope that helps
