Example of jboss-esb.xml with JCA provider

[lafbarbosa]

Hi people,

Please, does anybody have already seen an example of JCA provider into a jboss-esb.xml?

I ask this because I've found (into the jbossesb-1.0.1.xsd) the following attributes for the jms-jca-provider tag:
- adapter:the artifact containing the resource adapter; type string
- endpointClass: the class name of the JCA endpoint; type string
- messagingType: the class name of the messaging specific interface; type string
- jcaBridge: the class name of the JCA Bridge; type string
- transacted: the transacted flag; type boolean
- providerAdapterJNDI: the JNDI location of an alternate provider adapter

but, I haven't seen any example in quickstart samples.

Thanks in advance!

Regards,

Luiz

You do not need to do anything with these attributes unless you are overriding the current JCA configuration. The jms-jca-provider already provides default values for these.

Hi Kevin,

Ok, but if I don't use these attributes related above, which is the difference between use a jms-provider and a jms-jca-provider? Because it seems to be exactly the same.

For example:

<jms-provider name="CallbackQueue-JMS-Provider" connection-factory="ConnectionFactory">
<jms-bus busid="jBPMCallbackBus">
<jms-message-filter dest-type="QUEUE" dest-name="queue/CallbackQueue"/>
</jms-bus>
</jms-provider>
<jms-jca-provider name="CallbackQueue-JMS-Provider" connection-factory="ConnectionFactory">
<jms-bus busid="jBPMCallbackBus">
<jms-message-filter dest-type="QUEUE" dest-name="queue/CallbackQueue"/>
</jms-bus>
</jms-jca-provider>


Could you give me some idea about the usage of each one?

Thanks in advance!

Regards,

Luiz

The similarity in the configuration is intentional.

The jca-jms-provider uses JCA to deliver the JMS messages into the ESB and can therefore take advantage of encompassing transactions, the jms-provider uses the normal JMS connections and is not transactional.

You should be able to change a jms-provider into a jca-jms-provider is you wish to use a transactional context.
