NetBeans provides syntax highlighting javadoc help if the JDK javadocs are installed. I found this out by initially not seeing them while running NetBeans under linux. After I installed 'open6-jdk-javadocs' using the Synaptics package program they suddenly worked. I now use an iMac which doesn't use Synaptics to maintain installations; what steps do I take to make NetBeans see the javadocs? Should I manually install them in the iMac java directory?
