Problem Using Session Bean In A Simple Seam Web Project (Nam

elvisisking Jan 3, 2008 9:50 AM

I'm using Red Hat Develop Studio 1.0.0 CR1 and am new to web development so I'm sure there is a simple solution. These steps recreate the problem:

1. Created a Seam Web Project (using all defaults)
2. Created a Seam Action. Named the seam component "register" and the Java class "Register."
3. In session bean/action class added "@Stateful" and "@Scope(ScopeType.SESSION)" tags, made class Serializable, and added "@Destroy" and "@Remove" tags to new method "destroy()"
4. Refactored out an interface from the bean class, added "@Local" tag to the interface
5. When I "Run on Server" I noticed this in console log: [Component] Component: register, scope: CONVERSATION, type: STATEFUL_SESSION_BEAN, class: org.domain.simple.session.Register, JNDI: Register/local
6. On web page that displays, hit the command button referencing the session bean/action method and get the following error: org.jboss.seam.InstantiationException: Could not instantiate Seam component: register
Caused by: javax.naming.NameNotFoundException: Register not bound

Thanks for any help you can provide.

if you used all defaults then you created a War project; @Stateful is only sensible in context of an Ear project.

Otherwise it all sounds like something better asked about in the seam user forum.

I am getting the same problem as seen by Elvis.

@Max, are you saying that instead of creating a Seam Web Project, we need to create a 'J2EE/Enterprise Appication Project' using the wizard?

Is there any way to have the IDE tell us about this problem?

no - i'm saying that on the last page of the seam wizard are two options; war and ear.

It is by default war (which uses pojo's) and that if you want to use Session Beans need to select Ear.

Max,

Thanks! That cleared it up, but raised another somewhat related question.

What are the pros and cons associated with using SEAM POJOs only and NOT using EJB3 session beans at all.
