Sorry I don’t have any experience with db4o. The only thing I can think is that the warp page on the db40 module (http://www.wideplay.com/webextensions%3A%3Ajpaintegration22) does seem to not show :

Configuration config = Db4o.newConfiguration();
bind(Configuration.class).toInstance(config);

Thanks,

You will need to start the db4o server via Db4oServer before executing tests or the webapp.

The warp persist 2.0-20090214 project is located here:

http://warp-persist.googlecode.com/svn/tags/20090214/warp-persist/dist/warp-persist-2.0-20090214.zip

After this it works fine and I updated to
warp persist 2.0-20090214 and google guice 2.0. I had to change the filter according to this information:

http://www.atomicgamer.com/dev/2009/10/wicket-guice-2-0-warp-persist-2-0/

Then I moved to db4o where I had to insert a ‘deleteAll’ in test-setup before all tests passed.

But now if I want to run the webapp I get:

java.lang.IllegalArgumentException: Configuration already used.

Do you have any suggestions?

Here is the guice setup snippet, called in Module.configure():

install(PersistenceService.usingDb4o().across(UnitOfWork.REQUEST).
forAll(Matchers.any(), Matchers.annotatedWith(Transactional.class)).buildModule());

bind(EventDao.class).to(EventDaoDb4o.class);

Configuration config = Db4o.newConfiguration();
bind(Configuration.class).toInstance(config);

bindConstant().annotatedWith(Names.named(Db4Objects.HOST)).to(Db4oServer.HOST);
bindConstant().annotatedWith(Names.named(Db4Objects.PORT)).to(Db4oServer.PORT);
bindConstant().annotatedWith(Names.named(Db4Objects.USER)).to(Db4oServer.USER);
bindConstant().annotatedWith(Names.named(Db4Objects.PASSWORD)).to(Db4oServer.PASSWORD);

But no glass-fish & wicket? jboss? jeronimo? jee 5 is not bad such Wicket guy thinks (ok, j2ee is quite horrible) and jee app server world could enjoy to have quick, easy experiment of Wicket for web tier, and, maybe reverse also for a Wicket guy

@Dave - I did make project for spring, jpa and also wicket, spring from Leg Up on debian 5 and vista at office and Mac OSX at my home with Java 5 and maven 2.1.0 (what did you try?). Did you try your installed maven with other archetype (http://wicket.apache.org/quickstart). Is your .m2 folder clean - move it and and try again also. I did no try Java 6 with this but I think it will not be the problem.

Can you try changing this bit of the command line:
-DarchetypeCatalog=http://legup.googlecode.com/svn/repo/archetype-catalog.xml

to this:
-DarchetypeCatalog=http://legup.googlecode.com/svn/repo

and let me know if it works.
