Hibernate/Spring
by Chris Cranford-2

Rate this Message:
I have done a fair amount of reading today on the topic again and
developed a few simple classes to support my service, model, and dao architecture for using Hibernate 3.3.2 and Spring 2 with Struts2. The problem I am currently facing is I get a detached error when deleting an object and I get a null pointer exception in SessionImpl.java when I try to locate an object by its id. /* GenericDAO.java */ public T findById(Object id) { return(getEntityManager().find(clazz, id)); } public void delete(T entity) { getEntityManager().remove(entity); } Some posts I have seen say for the delete, you should use getReference() or merge() in order to get an association to the entity before you call the remove() method. I attempted to use the same type of logic with getReference() during the findById() and it failed. Am I missing something in my configuration with Hibernate/Spring with respect to the session factory or something that I need to revisit? It really seems as though I may have a missing component or a poor configuration somewhere. --------------------------------------------------------------------- To unsubscribe, e-mail: user-unsubscribe@...

From what you are saying, I would have a look at the :
http://static.springsource.org/spring/docs/2.5.6/api/org/springframework/orm/jpa/support/OpenEntityManagerInViewInterceptor.html My best guess is that this would fix your issue. If not, you probably have an issue with the way you are dealing with your entities. Denis.

good morning denis i sent chris a summary of working hibernate examples in Glassfish the getReference is a method from Ejb3Configuration the merge method comes from org.hibernate.ejb.AbstractEntityManagerImpl (and implements the sessions merge) whichever app server he will be implementing will have to be configured to serve his specific Bean as an EJBEntity..

Chris - I just happened to be learning Hibernate and have created an example application that uses Struts 2, Spring, and Hibernate together.
You can download the example application here: http://www.brucephillips.name/struts/Struts2_Spring_Hibernate_Example.zip After you unzip the archive, you'll find a README.txt in the project's root folder that will explain how to run the project. The application was created using Eclipse 3.5 with the Maven 2 plugin. The JDK used was JVM 1.6 on the Mac. You can import this project into Eclipse by using Eclipse's File - Import feature. You can also run the application using Maven. Navigate in a terminal (command) window to the project's root folder (the folder where pom.xml resides). Issue these commands: mvn clean mvn test (All 7 tests should pass successfully). mvn jetty:run When you see [INFO] Started Jetty Server open a web browser and navigate to http://localhost:8080/index.html. To stop the Jetty web server type CTRL-C in the terminal window. In my example application I have my DAO classes extend Spring's HibernateDaoSupport and I also use Spring's @Transactional annotation in the DAO classes. Both the Spring references below explain this technique (Spring Recipes especially provides helpful examples). References: Hibernate Made Easy, Cameron McKenzie, 2008 Spring Recipes, Gary Mak, 2008 Pro Spring 2.5, Jan Machacek and others, 2008 Bruce Phillips

Hi Martin,
I am building a Struts 2 / Spring / Hibernate application, using the JPA specification as it seems to be the case here. It is not required to go through all the pain of using EJB entities. I am running this application both in Websphere and Tomcat, without using the container at all. To me the problem is only a JPA / Hibernate problem, and Spring is totally able to handle that without having to rely on the container. Denis.
