understanding is that it should be placed under

WEB-INF/classes/persistence.xml
Try WEB-INF/classes/META-INF/persistence.xml

Thanks,

Hi Everyone,
I am mumbling so far with Geronimo 3.0.1, Eclipse Luna 4.0, and wanted to
develop a JPA aware JSF page with data helper class.
1. I've problem with persistence.xml doesnt seem to be seen by Geronimo , my
understanding is that it should be placed under
WEB-INF/classes/persistence.xml to be recognized..so it is.
org.apache.geronimo.common.DeploymentException: At least one deployment
at
org.apache.geronimo.common.DeploymentException.cleanse(DeploymentException.java:87)
at
org.apache.geronimo.deployment.Deployer.deploy(Deployer.java:150)
at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method)
org.apache.geronimo.common.DeploymentException: No default PersistenceUnit
specified, and none located
at
org.apache.geronimo.persistence.builder.PersistenceRefBuilder.findPersistenceUnitQuery(PersistenceRefBuilder.java:225)
at
my persistence.xml (tried on WEB-INF\classes\persistence.xml and
WEB-INF\persistence.xml) none seems to solve the problem
<?xml version="1.0" encoding="UTF-8" ?>
<persistence xmlns="http://java.sun.com/xml/ns/persistence"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/persistence
http://java.sun.com/xml/ns/persistence/persistence_1_0.xsd"
version="1.0">
<persistence-unit name="QueueStationPU" >
<description>This unit manages orders within a queue station.
</description>
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>
<jta-data-source>jdbc/QueueStationDS</jta-data-source>
<class>com.hahlabs.mf.model.entity.OrderEntity</class>
<class>com.hahlabs.mf.model.entity.PatientEntity</class>
<class>com.hahlabs.mf.model.entity.ActivityLogEntity</class>
</persistence-unit>
</persistence>
the part of code that references the above persistence-unit is the helper
class that actually stores a record in the database
@Stateless
public class PatientRegistry extends MFObject {
@PersistenceContext(unitName="QueueStationPU")
EntityManager em;
...
}
I wanted to use CMB with resource injection...
no entries related to persistence in either web.xml or geronimo-web.xml or
whatso ever
Any help in this area is much appreciated!
