After installing the Java 2Platform Standard Edition (J2SE) 5.0 Release 4 on my OS X server running QLA 3.5, the QLA server would not open, run or even uninstall. I had to do the following to revert it back to Java 1.4.2:
In Terminal, run the following commands:
$ su root
$ cd /
$ cd System/Library/Frameworks/JavaVM.Framework/Versions/
$ sudo rm -rf CurrentJDK
$ sudo ln -s 1.4.2 CurrentJDK
After executing the above mentioned commands you should be able to install QLA.
