Persistence Unit NOTYETINSTALLED

[ganton516]

I am trying to learn EJB3 on 4.0.4GA-Patch1, and am having trouble with my persistence unit.

The whole application is packaged in an EAR, with the entity beans in one jar, the session beans in another jar, and the web-app in a war.

The persistence.xml is packaged in the META-INF directory of the jar containing the entity beans.

I am trying a dependency injection on a stateless session bean, with the following code:

@PersistenceContext(unitName="users")
 protected EntityManager em;

with the following persistence.xml

<?xml version="1.0" encoding="UTF-8"?>

<persistence>
 <persistence-unit name="users">
 <jta-data-source>java:/usersDS</jta-data-source>
 <properties>
 <property name="hibernate.hbm2ddl.auto" value="create-drop"/>
 </properties>
 </persistence-unit>
</persistence>

and I get the following errors during deployment:

--- MBeans waiting for other MBeans ---
ObjectName: jboss.j2ee:ear=users.ear,jar=business.jar,name=UserManagerBean,ser
vice=EJB3
 State: NOTYETINSTALLED
 I Depend On:
 persistence.units:unitName=users

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---
ObjectName: persistence.units:unitName=users
 State: NOTYETINSTALLED
 Depends On Me:
 jboss.j2ee:ear=forums.ear,jar=business.jar,name=UserManagerBean,service=EJB3

Anybody know why the persistence unit isn't being registered, or if that is in fact the problem ?

Thanks in advance for help

I figured this out, my DD for persistence.xml was not named correctly.

Ganton,

I'm having this same problem. Can you elaborate on your solution? What do you mean by DD? Data Dictionary?

I am also experiencing this exact problem and have been searching for two days straight with no resolve. Please help!

I have troubles with Persistence unit too:

I had a similar problem. Make sure your datasource.xml file that defines your connection is in the server/default/deploy directory.

I found that if in my persistence.xml I had the jta-data-source set as java:/xyz then then in the datasource.xml the jndi-name needed to be just xyz on its own

When we apply tow injection on the same class in One web application like

1) EJB injection by @stateless

2) and Hibernet injection by  @PersistenceContext

Its ok and working fine

but like this way if you have two project in jboss (C:\jboss-4.2.3.GA\server\default\deploy) and both the project have the Object have the above things

It gives message

--- MBEANS THAT ARE THE ROOT CAUSE OF THE PROBLEM ---

ObjectName: persistence.units:unitName=hdgPersistCtxUnitName

  State: NOTYETINSTALLED

  Depends On Me:

    jboss.j2ee:ear=appOne.ear,jar=EOne.jar,name=CPProcess,service=EJB3

My single web application is working but as soon I deploy the second web application it show me the error.

I think that when a global PersistCtx will also load both object (web app1 and web app2) now when web app2 is loaded EJB injection can't be apply and wail for release of MBEANS from hibernet.

My web app2 is a copy of we app1 but I seperate the context, database, hibernet perstence context name, mssqlApp1-ds.xml and mssqlApp2-ds.xml

I found no issue with the Object have only  @PersistenceContext but not @stateless

or @stateless but not @PersistenceContext

Anyhow this is unsolved issue for me.
