Why am I receiving the exception below if the type of both entities is PersistentLogin? I thought that would mean they are in the same entity group, but I guess that is an incorrect assumption. Any ideas how to fix this? This is the code: // the class is marked with @Transactional @Override public final void removeUserTokens(final Stri...
I know in spring we all code to interface. So the implementation class should not be known to outside world at all. But it is a public class so anyone make an instance of the implementation class also. How do you prevent this? Do you make the constructor private?

Hi Guys, I'm facing a problem with Hibernate. My current project is a little game. In this game you have a Board which has many Fields each with a Token.

I've successfully set up a tutorial Spring Batch project. I'd really like to know if it's possible to make it multi-threaded at the "Spring level". The basic idea of what I want is to make a list of tasks or task steps and let them be picked up and worked on by independent threads, ideally out of a pool limited to 'n' number of threa...
This question comes from here but can be a totally independent question. I have a unit test with Spring 2.5.2 and activemq 5.2.0. I create a broker (useJmx is true) using "vm://localhost", fire a couple of messages to "myTopic1" open a jconsole to this process and I see MBeans under org.apache.activemq -> localhost -> Topic -> ActiveMQ....

Seems like a simple task. I have a webapp which requires a database connection. I'd like to be able to drop an updated .war file on this app server and load a new version without having to re-edit an applicationConfig.xml file to specify the database connection parameters for production. Is using the container to setup the data source ...

At the moment I'm trying to find a way to split development of some things used by all webapps, e.g. I have some helper classes that are the same for all projects. The problem is, I don't want to use only classes, bu...

How can I inject dependencies into a deserialized bean? Some of my Spring beans should be serialized during the render-response phase of our JSF application, and then deserialized at the beginning of the next request. Some of those beans have dependencies which are scoped to the request. If I configure the dependencies with the scoped...
