Google Guice and JPA Injection - Strange error

Im currently working on a JPA Jersey Servlet and Im trying to use Guice for dependency injection. The Problem is, that I get the following error:

Exception while loading the app : java.lang.IllegalStateException: ContainerBase.addChild: start: org.apache.catalina.LifecycleException: com.google.inject.CreationException: Guice creation errors:

1) null returned by binding at com.google.inject.persist.jpa.JpaPersistModule.configurePersistence(JpaPersistModule.java:63)

2 errors

The code that i generating this error is:

install(new JpaPersistModule("theseen")); 
filter("/*").through(PersistFilter.class);

If I use the "standard" way by instantiating a EntitiManager and uncommenting these lines, nothing happens.

 EntityManagerFactory emf = Persistence
            .createEntityManagerFactory("theseen");
 EntityManager em = emf.createEntityManager();

 em.getTransaction().begin();
 em.merge(s);
 em.getTransaction().commit();

works like a charm. So I think the setup if the database connection must be ok.

What could these to errors possibly be? I tested the same App on another test environment and it works! Both machines use Glassfish 3.1, Eclipse Indigo with m2eclipse and m2wtp integration. I use Guice 3.0 with guice-persist 3.0 and guice-servlet 3.0. The machine where the app is working runs Ubuntu 11.04 with OpenJDK, the machine where problems occure uses Windows 7 with JDK1.6v26. I normally use a Datasource provided by Glassfish, but even using a plain persistence.xml is not working.

I am seriously confused... Any ideas what is wrong with Guice Injection for JPA?

Since nobody answered I went brute force:

Completely reinstall Glassfish and the WebApp worked...

Something must have been corrupted during the long months of testing here on my local machine.
