Every time I press F1 to open the help window I got the following into
my .log-file:

I am working on a Win 2000 Pro machine with 1 GB ram. Does anybody know
whats happening here and how I can get the help system running. I checked
some newsgroups and tried to find anything about it with google but until
yet I haven't found anything. Your help will be very very much appreciated!

TIA!
Ciao
Peter

Check the eclipse readme. You may have a servlet.jar in your jdk's
ext(ension) folder.

Checked this, found some servlet.jars but none of them is in the
classpath. I renamed all except the one in the eclipse-folder to check,
but still doesn't work :(

Renaming does not change the story, the jars in the ext folder get added to
the boot classpath of the jdk (regadless of the jar name), so their classes
will get loaded before those contributed by eclipse. Try removing them first
(well, back them up before removing :-) and give it a try.

None of these jars were in the ext-folder! I deleted them all, no change
so far... I've seen that this problem exists already in eclipse-bugzilla
#69124, but no solution yet. I keep on trying.

Thanks a lot!

Found it! The problem was caused by an older log4j jarfile in my lib/ext
folder. Removed it and everything works fine!
