Java installation
From OpenKM Documentation
You should check if there is a previous java version installed in your system. You can check it running this command:
$ java -version
It will tell you the installed version, if any. Keep in mind that OpenKM needs JDK 1.6 (or higher) to run. If you use a Debian based Linux distribution, you can install the Java JDK this way:
$ sudo aptitude install sun-java6-jdk
In case of you have other JDK installed (like GCJ) you can select the right one this way:
$ sudo update-alternatives --config java $ sudo update-alternatives --config javac
If you use a Windows based OS, download and install Java JDK from http://java.sun.com/javase/downloads/index.jsp. In other case visit http://java.sun.com for more information.
