it should still fix some issue I finally think I got what I wanted: Automatic transaction management. After reading about Springs Declarative Transaction Management and adding an AOP Proxy, I got it working. I added the following code to my servlet-context.xml and everything went fine:
code :
<tx:advice id="txAdvice" transaction-manager="transactionManager">
 <!-- the transactional semantics... -->
 <tx:attributes>
  <!-- all methods starting with 'get' are read-only -->
  <tx:method name="get*" read-only="true"/>
  <!-- other methods use the default transaction settings (see below) -->
  <tx:method name="*"/>
 </tx:attributes>
</tx:advice>

<!-- ensure that the above transactional advice runs for any execution
of an operation defined by the FooService interface -->
<aop:config>
 <aop:pointcut id="UserServiceOperation" expression="execution(* de.codemetrix.lokalit.model.database.UserService.*(..))"/>
 <aop:advisor advice-ref="txAdvice" pointcut-ref="UserServiceOperation"/>
</aop:config>

wish helps you When I looked into the code after the weekend the solution was right there...
The problem was obviously the HibernateUtil:
code :
private static final String CONFIG_FILE = "hibernate.cfg.xml";

Hope this helps Currently, gvNIX uses a Dandelion Datatables 0.9.2 custom-version which includes some patches than hadn't been applied until 0.10.0 (it was due to release-time problems).
As far I know, we didn't make any test over Tomcat 8, so I think you found a bug ;-). If you want, you could report it on github project. Now a days, I can't provide you any workaround to run it on Tomcat 8.

I hope this helps . My guess is that your application is not using the Spring JARs inside the webapp but the one provided by WebLogic and those can't "see" the Hibernate JAR inside the war.
To tell Weblogic to look into the war file, provide a WEB-INF/weblogic.xml with prefer-web-inf-classes set to true (this is required for Hibernate anyway because of the ANTLR version bundled in WLS):
