h2. Send a WS notification from a JBI message

When the petals-bc-soap component receives a JBI message on a topic-activated endpoint, it is transformed into a WS-notification message and published on the linked topic.

As an example of SOAP notification message, if the JBI message payload is :

{code:lang=xml}
<text>This is a sample of JBI message payload...</text>
{code}

and if it is published on the *'TopicSample'* topic, the SOAP body payload of the notification message will be :

{code:lang=xml}
<wsnt:Notify>
<wsnt:NotificationMessage>
<wsnt:SubscriptionReference>
<wsa:Address xmlns:wsa="http://www.w3.org/2005/08/addressing">
http://127.0.0.1:8084/wsn-consumer/services/consumer
</wsa:Address>
</wsnt:SubscriptionReference>
<wsnt:Topic Dialect="xsd:anyURI">TopicSample</wsnt:Topic>
<wsnt:ProducerReference>
<wsa:Address xmlns:wsa="http://www.w3.org/2005/08/addressing">
http://127.0.0.1:8084/wsn-producer/services/producer
</wsa:Address>
</wsnt:ProducerReference>
<wsnt:Message>
<text>This is a sample of JBI message payload...</text>
</wsnt:Message>
</wsnt:NotificationMessage>
</wsnt:Notify>
{code}

h2. Using WS-Policy

The [Apache Rampart|http://ws.apache.org/rampart/] module is used to apply policies when calling an external Web Service (ie in consumer mode). The current section explains how to configure the component to use this feature.

h3. Configuration

h3. Usage

Once the Service Unit is deployed on the SOAP Binding Component, all the JBI messages sent to the new activated endpoint are transformed into SOAP messages and the Web Service client will use the Service Unit defined policy to call the Web Service. The Web Service client behaviour is exactly the same as a policy-enabled Axis2 based Web Service client.

An example of WS policy with PEtALS is provided in the PEtALS SOAP usecases at : [http://websvn.ow2.org/listing.php?repname=petals&path=/trunk/configurations/petals-soap/petals-soap-policy/|http://websvn.ow2.org/listing.php?repname=petals&path=/trunk/configurations/petals-soap/petals-soap-policy/].



h1. Samples

The SOAP binding component samples are available as packaged use cases. You can find them on {{trunk/configurations/petals-soap}} directory of the [Petals ESB forge|http://forge.ow2.org/plugins/scmsvn/index.php?group_id=213].

h1. Know problems

h2. "Transport out has not been set"

If the exception message "Transport out has not been set" occurs when invoking an external web-service, using the petals-bc-soap, it can be due to a wrong URL of the external web-service. Please check it and retry your test.
