Hi Jeff,
Is it possible that when you ran it, you selected a Application class
other than the one from your project?
(Right-Click on project -> Run As... WOApplication, then make sure you
are selecting _your_ Application class)
If that isn't it, Google is your friend:

I hope this helps.

OK, that got me a little further, but now I get a similar problem
with Main (see exception below). I tried adding
protected Class _mainClass()

to both Application and Session but that didn't help.

Hi Jeff,
Somehow it is picking up a Session class from one of the
frameworks included in your build path. As it's saying:
"org.apache.axis.session.Session" - which is _not_ the right
session class.
Instructions on how to fix are here: http://lists.apple.com/archives/webobjects-dev/2008/Jan/msg00063.html

OK, I got the PracticalUtilities JUnit tests to run with no
Failures and 4 Errors, so I've moved on to chapter 3 app. On
startup I get the below exception. Seems it gets confused as to
what Session class to use. I looked for references in the code
to Session, but the only thing I came up with was the Session
class itself (which extends WOSession), so I'm not sure what's
going on:
com.apress.practicalwo.chap3app.Application> Class 'Session'
exists (interface org.apache.axis.session.Session) but is not a

Hello,
I'm trying to setup the Practical Webobjects code in Eclipse
following the books Appendix. I'm getting stuck on trying to
run the JUnit tests on the PracticalUtilities project.
Everything seems to go fine, but the "Run" button on the Run
Diaglog stays "greyed out". I did select the "Run a single
test" radio button and entered the Test class
(com.apress.preacticalwo.practicalutilities.tests.AllTests),
along with entering the specified workding directory.
The project itself does have a red X on it, but nothing in the
project has one, so I've no idea why. Any ideas on what may
be causing this? I was able to run the database setup scripts
fine.
That red X might be important. Open the Problems view and have
a look.
