Hello Ranchers,

I've recently start to learn and integrate Spring and Hibernate to my Java web app (Struts2 as a presentation). I've googled a lot about tutorial and examples and so on. Well, everything seems ok and running based on the materials I've collected. but as long as I've deployed it on a hosting web server and got a Lot of Runtime java.lang.OutOfMemoryError exception, I wanted to clear things up to myself that everything I'm doing is correct as point of view of an expert, then assuming there are some issues about my Webserver Hosting or something else.
So here the Code:

web.xml


struts.xml


applicationContext-hibernate.xml


spring-hibernate-actions.xml


spring-hibernate-services.xml


spring-hibernate-daos.xml


FirstAction.java



FirstServiceImpl.java


FirstDAOImpl.java


I'd really appreciate if anyone could help me whether I was on a right path or something seems wrong or Exception-Throwing-Material on the above application development.

Regards,
Khosrow.

Actually it looks really clean to me.

There are a few suggestions, but for just starting out, they are really minor. Things you will learn as you learn more about Spring, like autowiring, And if you use recent Hibernate versions using the HibernateTemplate and HibernateDaoSupport is now antiquated. The reason why I say the last, is now you have a class that is coupled with a Spring class, the HibernateDaoSupport, so your Daos are no longer POJOs. Later, you might also like the Annotation route.

But again for a beginner that is great looking configuration and coding.
