install JDK from Oracle’s site.

I downloaded  jdk-7u17 for Linux 64bit.

mint hattori # ls *.tar.gz jdk-7u17-linux-x64.tar.gz

make a directory for JDK 1.7.0

mint jvm # mkdir /usr/lib/jvm/jdk1.7.0-oracle

extract jdk and move files under /usr/lib/jvm/jdk1.7.0-oracle directory.

mint hattori # tar xzvf jdk-7u17-linux-x64.tar.gz mint hattori # mv ./jdk1.7.0_17 /usr/lib/jvm/jdk1.7.0-oracle

change java version. select oracle java
