[jboss-user] [EJB 3.0] - EntityManagerFactory null from JNDI?
EntityManagerFactory is null in jndi. No errors, no warnings, notta just null or
"not found" etc.
Yep I've seen posts on this, but no good answer.
jboss-4.0.4.GA
So far my SLSB beans work remotely for unit tests.
But ...
How do you get an EntitManagerFactory from outside the container?
JNDI always returns either not found or null.
In my META-INF/persistence.xml file (of the deployed test jar):
<?xml version="1.0" encoding="UTF-8"?>
| <persistence>
| <persistence-unit name="fudb">
| <jta-data-source>java:/MySqlDS</jta-data-source>
| <exclude-unlisted-classes>false</exclude-unlisted-classes>
| <class>com.fubar.ads.clicks.model.DataDemographic</class>
| <properties>
| <property name="hibernate.hbm2ddl.auto"
value="update"/>
| <property name="hibernate.dialect"
value="org.hibernate.dialect.MySQLDialect"/>
| <property name="jboss.entity.manager.jndi.name"
value="fudb"/>
| <property name="jboss.entity.manager.factory.jndi.name"
value="fudbFactory"/>
| </properties>
| </persistence-unit>
| </persistence>
All of the following test methods fail:
| // testEMF() blows with javax.persistence.PersistenceException: No Persistence
provider for EntityManager named
|
| public void testEMF() throws Exception
| {
| EntityManagerFactory emf = Persistence.createEntityManagerFactory("fudb");
| assertNotNull("EntityManagerFactory not accessible.", emf );
| }
|
| public void testEMF2() throws Exception
| {
| InitialContext ctx = getInitialContext();
| Object em = ctx.lookup("java:/fudb");
| assertNotNull("obj is null.", em );
| }
|
| public void testEMF2b() throws Exception
| {
| InitialContext ctx = getInitialContext();
| Object em = ctx.lookup("fudb");
| assertNotNull("obj is null.", em );
| }
|
| public void testEMF3() throws Exception
| {
| InitialContext ctx = getInitialContext();
| Object em = ctx.lookup("java:/fudbFactory");
| assertNotNull("obj is null.", em );
| }
|
| public void testEMF3b() throws Exception
| {
| InitialContext ctx = getInitialContext();
| Object em = ctx.lookup("fudbFactory");
| assertNotNull("obj is null.", em );
| }
|
| public static InitialContext getInitialContext() throws Exception
| {
| Hashtable props = getInitialContextProperties();
| return new InitialContext(props);
| }
|
| private static Hashtable getInitialContextProperties()
| {
| Hashtable<String, Object> props = new Hashtable<String, Object>();
| props.put("java.naming.factory.initial",
"org.jnp.interfaces.NamingContextFactory" );
| //"org.jnp.interfaces.LocalOnlyContextFactory"
| props.put("java.naming.factory.url.pkgs",
"org.jboss.naming:org.jnp.interfaces");
| props.put("java.naming.provider.url",
"jnp://localhost:1099/");
| return props;
| }
|
And in JNDIView for Global Bindings:
fudbFactory: org.jboss.ejb3.entity.InjectedEntityManagerFactory:Reference Class Name:
org.jboss.ejb3.entity.InjectedEntityManagerFactory Type: nns Content: /fudbFactory
|
| fudb: org.jboss.ejb3.entity.TransactionScopedEntityManager:Reference Class Name:
org.jboss.ejb3.entity.TransactionScopedEntityManager Type: nns Content: /fudb
|
I've tried lots of random things due to my lack of full docs, so maybe my approach
totally wrong ... Why null in jndi? Is this a bug?
