No object bound to name EntityManagerFactory

[neander]

Hi,

I've got problems getting started with Seam using seam-gen. First of all my application-stack:
- jboss-seam-2.1.0.SP1
- Sun Java System Application Server 9.1 Update 2 (GlassfishV2U2)
- Oracle 10g

What did I do:
1) "seam setup": EAR, configured the Oracle-DB, generation from existing tables, RichFaces, Packagenames, etc. (nothing special from my point of view)
2) "seam create-project": works as expected
3) "seam generate": works as expected
4) In my Eclipse i did for the generated project a "Import existing project into workspace"
5) I executed the "deploy[default]"-target of the build.xml. The ant-log looks good.

My first attempt to deploy the generated ear of the dist-folder into glassfish appserver failed because of
missing ejbs in my jar-archive. in some article i found the solution in removing the entry
   <module>
      <ejb>reverse.jar</ejb>
   </module>
of the application.xml file. After that the deployment succeeded.

But the application will not work. When i try to open the app in my webbrowser i get the following error:
org.jboss.seam.InstantiationException: Could not instantiate Seam component: algDocumentList
     at org.jboss.seam.Component.newInstance(Component.java:2096)
     at org.jboss.seam.Component.getInstance(Component.java:1978)
...

with cause-by-execption:
Caused by: java.lang.IllegalArgumentException: EntityManagerFactory not found in JNDI : java:/reverseEntityManagerFactory
     at org.jboss.seam.persistence.ManagedPersistenceContext.getEntityManagerFactoryFromJndiOrValueBinding(ManagedPersistenceContext.java:231)
     at org.jboss.seam.persistence.ManagedPersistenceContext.initEntityManager(ManagedPersistenceContext.java:78)
...

and another cause-by-exception:
Caused by: javax.naming.NameNotFoundException: No object bound to name java:/reverseEntityManagerFactory
     at com.sun.enterprise.naming.NamingManagerImpl.lookup(NamingManagerImpl.java:834)
     at com.sun.enterprise.naming.java.javaURLContext.lookup(javaURLContext.java:218)
...
(after that cropped stack)

so obviously there is a problem trying to lookup the EntityManagerFactory, but i have no clue how to fix that.
here's the relevant part of the generated component.xml:
...
   <core:init debug="@debug@" jndi-pattern="@jndiPattern@"/>
   <core:manager concurrent-request-timeout="500"
                 conversation-timeout="120000"
                 conversation-id-parameter="cid"
                 parent-conversation-id-parameter="pid"/>
   <persistence:managed-persistence-context name="entityManager"
                                     auto-create="true"
                      persistence-unit-jndi-name="java:/reverseEntityManagerFactory"/>                         
   <drools:rule-base name="securityRules">
      <drools:rule-files>
         <value>/security.drl</value>
      </drools:rule-files>
   </drools:rule-base>
   <security:rule-based-permission-resolver security-rules="#{securityRules}"/>
   <security:identity authenticate-method="#{authenticator.authenticate}" remember-me="true"/>
...

i'm doing a poc for seam on glassfish and it's very important for me to get this thing running.
i hope somebody can help me through this.

Thanks in advance

We have glassfish examples you can look at.  It looks like they all add a persistence-unit-ref declaration, which I assume makes sure the JNDI binding happens

Hi Norman,

thank you for your answer. I checked all of the examples shipped with the seam-bundle but did'nt find any which uses a persistence-unit-ref in the web.xml. Even the jee5-booking example which runs quite well on glassfish does not use this feature.

I would be happy if you can give me a link to an example which uses this feature.

"persistence-unit-ref" isn't mentioned in the entire Seam Reference Documentation (Glassfish instructions included) ?!? Maybe that explains why the Glassfish instructions (chapter 39) don't work ..

Not sure if your question was answered yet, but I found this https://jira.jboss.org/jira/browse/JBSEAM-3612

If you made it work in Glassfish already, could you please send me your ear file so that I can configure mine?

Regards.

Can you post persistence.xml?
