I have downloaded from an Eclipse mirror the file
eclipse-SDK-3.0.1-macosx-carbon.tar.gz, put in the Applications
directory and started it up. It then comes up with an error message
about not being able to use Help:
Help cannot be displayed. The embedded application server could not
run help web application. Check the log for details.
and Exception Stack Trace:

How is that possible? How can it be remedied? (I even have recent
versions of log4j and commons-logging in my /Library/Java/Extensions
-- allthough removing them makes no difference). Did I forget
something important?
Help is appreciated.
Running Mac OS X 10.3.5 with the latest Java142Update2.
