Hi All,
I've spent the last few days trying configure the JMS Adapter to consume an ActiveMQ topic on a remote host.
Here's what I've done so far.
I've deployed the required activemq libraries by using the Oracle ant task (publish-shared-library) to the propery deployerURI.
I've installed JDeveloper and coded a ESB Designer Application, which is very simple. All it does is it consumes a message off an ActiveMQ Topic, and routes it to a FileAdapter.
This is very very complex (probably around 20 detailed steps) to get to this point.
I'm trying to use the built in Oracle JMS Adapter's TopicConnectionFactory (eis/Jms/TopicConnectionFactory) and it tries to connect to the topic 5x, and outputs an error:
<SUPPL_DETAIL><![CDATA[ORABPEL-12134
ERRJMS_ERR_CR_TOPIC_CONS.
Error while creating Topic consumer:.
Please examine the log file to determine the problem.

Alternatively, I've also tried to modify the oc4j-xml for the jms adapter located here to have a custom entry for ActiveMQ. When I try to do that, I get a no class found error. Here's what I put for my entry:
<connector-factory location="eis/activeMQ/Topic" connector-name="activemq-rar">
<config-property name="connectionFactoryLocation" value="ConnectionFactory"/>
<config-property name="factoryProperties" value="java.naming.factory.initial=org.apache.activemq.jndi.ActiveMQInitialContextFactory; java.naming.provider.url=tcp://hostname:61616"/>
<config-property name="acknowledgeMode" value="AUTO_ACKNOWLEDGE"/>
<config-property name="isTopic" value="true"/>
<config-property name="isTransacted" value="false"/>
<config-property name="username" value=""/>
<config-property name="password" value=""/>
<connection-pooling use="none">
</connection-pooling>
<security-config use="none">
</security-config>
</connector-factory>
I have confirmed through my SOA Console that my shared library is loaded (containing the proper activemq.rar file)
The error when using this configuration is this:
<PAYLOAD>

Not very useful... as it doesn't say what class isn't found!!
Has anyone been able to configure the JMS Adapter that's part of the Oracle SOA suite to listen to a topic?
