== setJava & setDefaultJava == Note that due to the switch to jpackge, commands like setJava and setDefaultJava are not available anymore. Instead, we use the update-alternative system now! For setting the default JRE, call -- as root -- the following command: update-alternatives --config java For setting the default JDK, call -- as root -- the following command: update-alternatives --config javac Right now, there is no replacement for setJava ... the described commands set the JRE / JDK system wide.
