WSO2 ESB custom properties for Smooks mediator

Question

I need to use some configuration settings to transform message with Smooks mediator. For example I want to inject a base URL into attribute value of outgoing xml during transformation.

In Java I'd do it by adding beans to ExecutionContext. Looking at SmooksMediator code I do not see this. Can I do it somehow or I should extend and recompile SmooksMediator to supply properties form MessageContext?

For the input as the Smooks mediator we can feed only one stream from the ESB. So if you want to transform a message by injecting a property, you can't achieve it with the smooks mediator.

Use XSLT mediator for this [1]. When configuring the XSLT mediator you can define properties to be passed into the transformation.

ex:

 <xslt key="orderTransformer">
   <property expression="get-property('name')" name="name"/>
   <property expression="get-property('email')" name="email"/>
</xslt>

Then inside the XSLT you can define the two properties as below,

<xsl:param name="email"/>
<xsl:param name="name"/>

and use them appropraitely as $email and $name in templates.

<ns1:email>
        <xsl:value-of select="$email"/>
    </ns1:email>
    <ns1:name>
        <xsl:value-of select="$name"/>
    </ns1:name>

As alternative we used Enrich mediator to 'glue' together 2 xml documents and process them in Smooks... — adnecs, Mar 26 '13 at 06:59

The whole configuration details of Smooks mediator can be found from [1].

Else you can go for a custom mediator to perform your exact task. Detail on custom mediator can be found from [2].
