Re: [Springframework-developer] Giving up

[Lars F. <lar...@gm...>]

Hi Jürgen,

you're just too smart ...

My previous mail explaining the error somehow got lost in cyberspace.

Still don't know what I was struggling with. It just doesn't make any sense
(that it doesn't work) and that's why I was so frustrated.

Just started everything from scratch (and I mean everything - even wrote
a new build.xml). Before I used the tutorial as starting point.

The example behaves as expected, there's only one thing I'm wondering
about:

I've change the MySQL stuff to Postgres - no problem. At this point I do
NOT provide the database table for the example object.  The application
starts up fine and does not tell me anything about a mapping problem.
Is this the default behaviour ?

Another question about WebWork (2). I know the difference about Spring and
WebWork and that it's 'no problem' to combine the two frameworks. 
But does it make any sense ? Is WebWork MVC superior ?
IMO it does make more sense to stay with Spring alone so you don't have
to deal with two technologies.

Thanks
Lars
