  • 0

I have recently got a new computer and I have put Eclipse Helios on there. Before, on my old computer, when I used the control-assist (Ctrl + Space) and highlighted the suggested methods, the Javadoc for that method used to appear at the side of the control assist pop up window with the method description and parameters etc…

However, on my new computer this Javadoc doesn’t appear and only the method suggestions appear – but even the arguments for the methods aren’t named (they’re just called arg0, arg1 and so on). The only thing I can think of that is different on the new install is ZoneAlarm but as far as I can see I have allowed eclipse through the firewall; unless it’s something to do with Java itself.

This feature is really useful to me so any advice on how to resolve this issue would be greatly appreciated. Thanks in advance.

    Eclipse is using a JRE instead of a JDK as the default Java.

    • Download and install a JDK.
    • In Eclipse Preferences, Java -> Installed JRE’s. Use “Add” or “Search” to locate and add the JDK just installed.
    • Move the check mark indicating the default Java to the newly found JDK.
    • Allow the workspace to rebuild.
