    mark4071 - 2006-12-29

    I can run the standalone version without any problems. It looks great. I installed the plugin as per the directions: unzipped into the eclipse dir and restarted w/ -clean. When I open the preferences page I get a message:

    Unable to open the selected preference page.

    Reason:
    Plug-in net.sourceforge.sqlexplorer was unable to load class net.sourceforge.sqlexplorer.preferences.GeneralPreferencePage

    Trying to open the perspective fails also. Under manage configurations -> show properties -> status, it says "the feature is configured properly". My workspace log is copied below. I'm using java version 1.5.0_06. Any help would be greatly appreciated.

      I am experiencing the same problem:

      [quote]Unable to open the selected preference page.
      Reason:
      Plug-in net.sourceforge.sqlexplorer was unable to load class net.sourceforge.sqlexplorer.preferences.GeneralPreferencePage
      [/quote]

      I must mention that I followed exactly the steps on the site:
      1) Downloaded the zip
      2) Unzipped on the eclipse directory

      I noticed that the files were unzipped on their own directories correctly (plugins and features).

      Just another notice: The eclipse update mechanism that the site claims to be working is not working at all. :(
