Hey all,
me and some guys from the institute have investigated some common,
probable issues or faults, but we still get the NCDF-Error, after
exporting out plugins as features and installing them into another
eclipse instance (both 3.4 releases).
The class, which is not found is exported and still present in the
exported plugin, as well as its package is exported in the runtime
section of MANIFEST.MF. We still have cleaned, reexported etc. the whole
scenario, but after exporting the feature, the class won't be found.
Even if we create a new, cleaned workspace, we have no success. From
inside the development ide or by debugging it by running an Eclipse
Application, it works! Very strange.
Here is the stack trace:
java.lang.NoClassDefFoundError:

Any ideas, we have no more :(

How are you installing it to another eclipse? Export -> Install into host. Repository?
Another way to do the same thing could be by creating an update site.

Currently, we're copying the files into the target platform directories.

3.4 have P2 provisioner to handle installing/updating the plugins. The 3.3 way of copying the
plugins to eclipse\plugins won't work. You need to drop them to eclipse\dropins location. The
recommended way to go about it would to build an update site. And update you other eclipse
installation using it.
