[JBoss Getting Started Documentation] - Session bean in jar 1 can't access entity bean in jar 2 alth
by soulreaper
Hello Folks
I have a rather basic question concerning the deployment of EJB3 beans. My application consists of three projects: shopdemo-data, shopdemo-business and shopdemo-web, all packaged within their own jars (or war for the web package). I have packaged all three of those archives inside one ear which contains the following application.xml file in the META-INF directory.
<?xml version="1.0" encoding="UTF-8"?>
| <application xmlns="http://java.sun.com/xml/ns/j2ee"
| xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.4"
| xsi:schemaLocation="http://java.sun.com/xml/ns/j2ee
| http://java.sun.com/xml/ns/j2ee/application_1_4.xsd">
| <display-name>shopdemo</display-name>
| <module id="myeclipse.1168274010125">
| <web>
| <web-uri>shopdemo-web.war</web-uri>
| <context-root>/shopdemo</context-root>
| </web>
| </module>
| <module id="myeclipse.1168274038515">
| <ejb>shopdemo-business.jar</ejb>
| </module>
| <module id="myeclipse.1168274010281">
| <ejb>shopdemo-data.jar</ejb>
| </module>
| </application>
My session beans in the business project get properly deployed as well as the entity beans in the data project. They are all registered as expected. (imo)
The Problem comes when i access my stateless session beans which in turn try to access the entity beans. When i do that, i get the following error:

So i guess the entity beans from the data package are not know to the session beans in the buisiness package.
Btw... when i put the entity beans and the session beans in one .jar inside the .ear, they find each other as expected.
I hope anybody can help me out. thanks in advance.

[Microcontainer] - Re: Beans loading with Microcontainer in JBoss AS

Yes, but as a separate deployer, right?

MC as an IoC is a lot more than Spring.
But it is meant for different purpose - app. server kernel, service state machine... not so much with huge Utils and good alround hooks.
We are working on it to provide better hooks, more documentation, examples, ...

| So I has beans I declared in jboss-beans.xml. To load them I need a kernel controller as Wiki says. Well, I create ActionFactory with the kernel controller in it and expected using it as a factory for other beans (defined in jboss-beans.xml). The question is how to create ActionFactory. If it was Spring I would use some factory class provided by Spring. But here I didn't find a common approach to get the class instance. What should I do to get ActionFactory instance and then call getBean("addProvider").

There are ways - register bean into JNDI, MBeanServer, ... And then get them out from there as well.
I agree, should be better documented, but currently you are on your own - hopefully not for long.
