Hi,
The POM for this version of OpenJPA refers to the following dependency:
<dependency>
<groupId>org.apache.geronimo.specs</groupId>
<artifactId>geronimo-jpa_3.0_spec</artifactId>
</dependency>
This is the jar that contains all of the javax.persistence classes.
You may need the other dependencies listed in the OpenJPA POM too.
For reasons best known to themselves the Open* guys decided to package
their own versions of the javax.* classes, rather than using the
standard ones. They are normally found in the
org.apache.geronimo.specs group.
Cheers,
Steve C

What kind of project is this -- jar, war, ear, etc? And are you sure
the artifact providing the Persistence class is available in the

Are you sure the type=pom is appropriate for the openjpa artifact?
This was wrong of course, thank you. I've tried too many
configurations
for openjpa...The correct configuration would be:
<dependency>
<groupId>org.apache.openjpa</groupId>
<artifactId>openjpa</artifactId>
<version>1.2.0</version>
<type>jar</type>
<scope>compile</scope>
</dependency>
The persistence-api is just that, an API, eventually someone has to
provide an implementation somewhere in the project for things to
work.
I've used an example from the manual of openjpa, but now I found a way
to solve my issue by using a EJB injection. Hopefully this will work
with two databases.
I installed the J2EE-SDK, but this didn't solve my issue...for now I
will use the injection.
Thank you for your answer!
