Hi,
I'm trying to use db4o (a lightweight OO db) from inside an eclipse
plugin. However, db4o, which
uses the Thread.currentThread().getContextLoader() cannot find some of its
classes.
Now, I know that from within the plugin, the db4o.jar partially loads,
because it loads enough to
throw its own error messages about not being able to load other classes
within the same jar.
looking for help, or if you have used db4o from within an eclipse plugin,
Chris

Another guess: the Context classloader does not know about the
plugin location. This is at least happening, if you use the xerces
factories. Search the wiki for classloader and xerces to get a
'pattern', how to solve this. Something with setting the context
classloader to the classloader of your current class , doing the
operation and then put the opld context classlaoder back.
Jan, debugged this problem for about a day...
