openjpa/karaf

Hi all,

I am trying to get a project that uses OpenJPA deployed as a Service in
the Apache Karaf OSGi container.  I am getting an exception when I do an
osgi:install of my project.  The exception message is:

javax.persistence.PersistenceException: No persistence providers for 
"rsp" after trying the following discovered implementations: NONE


This is what my META-INF/persistence.xml looks like:

<?xml version="1.0"?>

<persistence xmlns="http://java.sun.com/xml/ns/persistence" 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" version="1.0">

   <persistence-unit name="rsp">

 
<provider>org.apache.openjpa.persistence.PersistenceProviderImpl</provider>

....snip classes....

     <properties>

       <property name="openjpa.ConnectionURL" 
value="jdbc:postgresql://localhost:5432/rsp"/>

       <property name="openjpa.ConnectionDriverName" 
value="org.postgresql.Driver"/>

       <property name="openjpa.ConnectionUserName" value=""/>

       <property name="openjpa.ConnectionPassword" value=""/>

       <property name="openjpa.Log" value="DefaultLevel=WARN, Tool=INFO"/>

     </properties>

   </persistence-unit>

</persistence>


Here is a list of relevant installed bundles:

[ 102] [Active     ] [            ] [   60] Commons Collections (3.2.1)

The Karaf version is 1.5.0-SNAPSHOT.

Any insight on how to remedy this error would be great &, of course, let
me know if I need to provide more info.

Thanks,

Jason,

I don't know whether this will help: http://yaytay.wordpress.com/2010/05/13/lsned-33-openjpa-in-apache-felix/
Might be more basic that what you are looking for.

Jim

Re: openjpa/karaf

Posted by Guillaume Nodet <gn...@gmail.com>.
The OSGi Enterprise Expert Group has released a specification around using
JPA in OSGi.
You may want to have a look at the Aries project (
http://incubator.apache.org/aries/) which provides an implementation of this
spec.
You should be able to find some examples along with the implementation.
