java spring spring-mvc spring-data-jpa hessian

Autowiring fails: Not an managed Type

I have a big problem in my diploma project and would be very glad if you guys could help me! I made a Maven Multi Module Project and have 3 "Core-projects"

NaviClean: (Parent)
NaviCleanDomain: contains the domain model with all my entities and an interface MeinRemoteDienst which is needed by NaviCleanServer and NaviCleanCleint for the Hessianprotocol
NaviCleanClient: conatins the GUI and a Hessian connection to NaviCleanServer
NaviCleanServer: Here are my repositories, my connection to the DB and the Implementation of the interface einRemoteDienst NaviCleanServer & NaviCleanClient have NaviCleanDomain in Maven as Dependency.

Now every time I try to start the Server on my Tomcat I get the following error:

ERROR: org.springframework.web.context.ContextLoader - Context initialization failed
org.springframework.beans.factory.BeanCreationException:

2. I insertet in my persitence.xml my domainmodel an repositories manually. The result was a "green" test but I wasn't still able to start the server...

Thanks alot in advance!!! I can't imagine what it would be without you :)

Solution

I got an very helpful advice from Oliver Gierke:

The last exception you get actually indicates a problem with your JPA setup. "Not a managed bean" means not a type the JPA provider is aware of. If you're setting up a Spring based JPA application I'd recommend to configure the "packagesToScan" property on the LocalContainerEntityManagerFactory you have configured to the package that contains your JPA entities. Alternatively you can list all your entity classes in persistence.xml, but that's usually more cumbersome.

The former error you got (NoClassDefFound) indicates the class mentioned is not available on the projects classpath. So you might wanna check the inter module dependencies you have. As the two relevant classes seem to be located in the same module it might also just be an issue with an incomplete deployment to Tomcat (WTP is kind of bitchy sometimes). I'd definitely recommend to run a test for verification (as you already did). As this seems to lead you to a different exception, I guess it's really some Eclipse glitch

Thanks!
