I have installed the Coherence Tab Pack and Twitter Action console plugins to the Oracle Java mission Control. But when I open the Console, it says:
No plug-ins available! Could not create the Plugin tab.
Make sure to set the JConsole plug-ins directory in preferences to point to a directory where you have JConsole plugins.
The error was: Could not find anz valid plug-ins in C:\Program Files\Java\jdk1.7.0_40\lib\missioncontrol\plugins. Please check the plug-in path in the preferences.
