Chuck,
Thanks for your input. I took your advice and reinstalled Eclipse
3.2.2 and stable WOLips. Reconstructed the WOApp following guidelines
in Janine's Tutorial throwing same exception error while trying to
run the WOApp:
[2007-07-14 21:21:03 EDT] <WorkerThread0>
<com.webobjects.appserver._private.WOComponentRequestHandler>:
Exception occurred while handling request:

Any suggestions?

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:
[2007-07-14 15:14:54 EDT] <main> null
