Tomcat Injection

[ericp56]

Hello,

After reading some documentation, I though I had my injection code worked
out, but apparently not.

I am using Tomcat with OpenJPA.

In my class, I have:
        @PersistenceUnit(unitName = "CallScheduler")
        private @Resource(name="bean/OpenJPAEMF")OpenJPAEntityManagerFactory emf;
In my META-INF/context.xml, I have:
        <Resource name="bean/OpenJPAEMF" auth="Container"
        factory="org.apache.openjpa.persistence.OpenJPAEntityManagerFactory"
        type="org.apache.openjpa.persistence.OpenJPAEntityManagerFactory.class" />

While executing a method in my class,  emf is still null.

How should I instantiate emf?  I am under the impression that
OpenJPAPersistence.createEntityManagerFactory is for unmanaged code...

Eric

I tried:
        emf = OpenJPAPersistence.getEntityManagerFactory();

but it doesn't find persistence.xml, and raises:
        <openjpa-1.1.0-r422266:657916 fatal user error>
        org.apache.openjpa.persistence.ArgumentException: A JDBC Driver or
DataSource class name
        must be specified in the ConnectionDriverName property.

Are there any samples out there?  The ones included with OpenJPA don't
include any managed resources.

Try this:
http://java.sun.com/javaee/5/docs/api/javax/persistence/Persistence.html

For me it worked as soon as OpenJPA was able to find persistence.xml via the classpath.
Alternatively you can provide the whole configuration via the map.

... on second thought:
Does Tomcat do dependency injection at all? In my eyes it is a servlet container, not an application server. You might want to change to Glassfish, Geronimo or JBoss.

But maybe such behaviour has been introduced to Tomcat and noone ever informed me about it... ;-)
