Hi all,
I have been running into an exception lately and can't seem to
remedy the problem. I am getting a
"javax.persistence.TransactionRequiredException: No transaction
currently active" exception. I am using Karaf v2.2.8, ActiveMQ
5.6.0, OpenJPA 2.1.1, and CXF 2.6.1. I followed the Apache Aries
sample blog application, so there is a datasource registered via
blueprint...looks like this:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";

default-activation="lazy">

....snip....
</cm:default-properties>
</cm:property-placeholder>

<property name="databaseName" value="${databaseName}" />
<property name="portNumber" value="${port}" />
</bean>
<service id="mapseqXADataSource" ref="mapseq-ds-jta"
interface="javax.sql.XADataSource">

<entry key="osgi.jndi.service.name" value="jdbc/mapseqJTA" />
</service-properties>
</service>
<bean id="mapseq-ds-no-jta"
class="org.postgresql.ds.PGPoolingDataSource">

interface="javax.sql.DataSource">
<service-properties>

value="jdbc/mapseqNoJTA" />
</service-properties>
</service>
</blueprint>
Here is the persistence.xml:
<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

<property name="openjpa.DataCache" value="false" />
<property name="openjpa.QueryCache" value="false" />
</properties>
</persistence-unit>
</persistence>
And finally, the blueprint.xml file to register JPA DAO services:
<?xml version="1.0" encoding="UTF-8"?>
<blueprint xmlns="http://www.osgi.org/xmlns/blueprint/v1.0.0";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";

default-activation="lazy">
<bean id="accessControlDAOImpl"
class="edu.unc.mapseq.dao.jpa.AccessControlDAOImpl"
init-method="init">
<tx:transaction method="*" value="Required" />
<jpa:context property="entityManager" unitname="mapseq" />
</bean>
<service ref="accessControlDAOImpl"
interface="edu.unc.mapseq.dao.AccessControlDAO" />
...snip...
</blueprint>
Here is part of the stacktrace:

The exception occurs whenever I try to do anything that is
transaction related (like persisting an entity). I have set the
logging in Karaf to DEBUG and I can't seem to find anything out
of the ordinary. Anyone seen this before??? Suggested solutions?
Suggestions for debugging further?
Regards,
Jason
