Errors in Stopping tomcat 7 server when Hibernate 4 is used

Question

We have used Hibernate jars in spring application. Data persistence is done by Java Persistence API using EntityManagerFactory being injected via context xml.

When we switched to Hibernate 4, the application is not getting stopped when it is deployed in tomcat 7. Following is the error.

SEVERE: A child container failed during stop
    java.util.concurrent.ExecutionException: org.apache.catalina.LifecycleException: Failed to stop component [StandardEngine[Catalina].StandardHost[localhost].StandardContext[/applicationName]

Could anyone suggest what could be the problem in stopping tomcat??

Answer 1

You're going to have to post more than just the stacktrace. I would imagine this is stemming from your injection of your EntityManager into one of your beans. Could you post a sample of one of your beans showing your injection?

Should be similar to:
