Hello friends,

I am trying to run ZK With Spring JPA And A Model-View-Controller Pattern described on link alias

I am using ZK 5.0.4 + SPRING 3.0.4 + JPA + JBOSS 5.1 for that.

Files web.xml and zk.zml are under /WEB-INF/ folder of the project.

Hi Amar,

Sorry I had not seen your post until today. Thanks for trying out my code so hard.

I have committed minor tweaks to get the sourcecode for my sample app (the one linked to on the mvc4 article) to have a cleaner web.xml for JBoss. I also upgraded my sample app to ZK5.0.5 and Spring3.0.5 and also downgraded the hibernate to 3.3.1.ga which JBoss5.1 runs.

Unfortunately after all that here is an issue with jboss running with

<tx:annotation-driven />

on jboss5.1. It gives an error

Error creating bean with name 'entityManagerFactory' defined in class path resource [spring-context.xml]: Invocation of init method failed; nested exception is java.lang.RuntimeException: error trying to scan <jar-file>: vfsfile:/home/simon/opt/jboss-5.1.0.GA/server/default/deploy/zktodo2-1.3.war/WEB-INF/classes/

This is discussed on this jboss thread Spring Component Auto Detection. Basically you can either go the whole xml route (no nice spring annotations) or you can follow up on the approaches on that thread if you need to use jboss.

Since it is a general spring issue with Spring and the way jboss deploys files I am sure that there will be a few more posts around to get over that particular issue if you are must use jboss. Personally I know is a great container but it sure is so, so, so slow to startup and use over jetty if you just want have a zk app. Spring lets you easily do all that other stuff like sending email and whatever else most typical webapps need to do without a big j2ee container.
