• Could not create the view: Plug-in org.openntf.filenavigator was unable to load class org.openntf.filenavigator.views.FileTreeView

    By Andrew J Walter 1 decade ago

    Installed Plugin v1.4 on Lotus Notes 8.5.1 on MAC OS X 10.5.8 using local deployment method. Successful install message at end. When I expand File Navigator - Preferences or side panel I get error - java.lang.UnsupportedClasVersionError

    If I expand details from sidepanel error I see -

    Could not create the view: Plug-in org.openntf.filenavigator was unable to load class org.openntf.filenavigator.views.FileTreeView.

    I asume I have an incorrect version of a class.

    Can you guide me on how to identify the cause and resolve it ?

    More detail :
