Well, I tried again. Deleted all haystack-related files in eclipse's
plugins and features directory, and installed haystack again through
eclipse's update function. Today it downloaded correctly (don't know
what went wrong yesterday), then went on to search my eclipse working
directory, downloaded some ontologies etc from the web, restarted
eclipse and everything looked fine.
Then I tried "Window -> Open perspective -> Haystack tabbed screen".
This opened a tabbed perspective with the tabs I had open in my Java
perspective. Looked OK. When, however, I tried "Haystack -> Home" from
the menu, I got a tab titled
"
http://haystack.lcs.mit.edu/data/operations#startingPoints" having an
ugly error icon and the text "Unable to create this part due to an
internal error. Reason for the failure: An unexpected exception was
thrown." Asking for details I got:
java.lang.NullPointerException
