Anthony,
Eclipse 3.3 and the WOLips nightly build should be considered
unstable and bleeding edge. I strongly recommend that you not use it
until it has settled down. You are pretty much on your own with
3.3. Instead, use Eclipse 3.2 and the stable WOLips build.

Hello all;
I am a newbie to webobjects but subscribed to this fine list and
have been following the discussion trails (don't know what to think
of the future of webobjects yet given the discussion but I really
want to try). You all seem like very smart and knowledgeable folks
and well-grounded in webobjects so I did not want to step in a cow
pile with my first foot forward. I want to thank Chuck Hill, Mike
Schrag and others for the valuable advice being provided on this
mailing list. I also want to thank Janine Sisk for the nice
beginner's tutorial and sample files. These have helped me a great
deal in getting started. However, I have already encountered a
problem which I cannot solve. Kindly give a newbie some advice,
please.
I successfully downloaded and installed Eclipse 3.3 and installed
the standard WOLips for 3.3 as well as other modules for Java, web
development, and C,C++ plugins. My goal is to deploy webobjects on
Apple MacOSX 10.4.10 using a Tomcat-6.0.13 container behind the
standard standard Apache-1.3.33 server with mod_jk and have this
system up, running nicely. I have also been able to plugin Tomcat-6
on the development system within Eclipse. I also have downloaded
and installed FrontBase-4.2.7 (which I really like, so far better
than all others I have looked at - Postgresql, MySQL, OpenBase,
Sqlite3, etc.).
I followed Janine's tutorial faithfully and first I noticed that
the build.xml is created but does not show up in the Package
Explorer as described in the tutorial. Everything else does.
Additionally, I get a java.lang.NullPointerException message in the
webbrowser while trying to Run the completed nhlpm webobject
tutorial example. Therefore, I have failed somewhere but cannot
discover it error yet. Any pointers would be appreciated. Console
output as follows:
