install Oracle JDK and JRE under OpenSUSE with integration to Firefox
First, download and install the rpm-Package from: https://www.java.com/de/download/linux_manual.jsp
Everything seems fine, you dont have to add anything to your $PATH but if you want to use the Java-Plugin in Firefox you have to add a symlink:
ln -s /usr/java/jre1.7.0_07/lib/amd64/libnpjp2.so /usr/lib64/browser-plugins/javaplugin.so
Keep in mind, that after an UpDate to a newer Version of Java the symlink has to be recreated according to the new version string in the installation path!
I don’t know why this link isn’t created by the postinstall script of the rpm. Possibly by a compatibility reason to an older rpm-based distro ?
