It has been so long since I have done a fresh install of fedora, I have forgotten all about the alternatives confusion. Thanks Eric. You can always force the JAVA_HOME to the installation directory of the jdk and include ${JAVA_HOME}/bin early in…

If you are using Fedora, then you probably have a lot of OpenJDK stuff clogging the works. I'm running Fedora as well and I had to do a bunch of stuff with alternatives in order to get OpenJDK out of my common path stuff. If you google for…

In your prior email you reference ~download and ~Download filenames are case sensitive on linux machines. If you did in fact type them correctly you have 2 different directorys.
