Example 3 - Adding a SOAPEnvelope type object as a property to a message
In this example, we add the SOAP envelope in a SOAP request as a property to a message. The Enrich mediator is useful in this scenario since adding the property directly using the Property mediator results in the SOAPEnvelope object being created as an OM type object. The OM type object created cannot be converted back to a SOAPEnvelope object.
| Code Block | ||
|---|---|---|
| ||
<enrich> <source type="envelope" clone="true"/> <target type="property" property="ExtractedEnvelope"/> </enrich> |

Added this content for the FAQ When ExtractedEnvelope is a SOAPEnvelope with OM type, why do we get "EnrichMediator SOAPEnvelope is expected" for SOAP requests? |
Example 4 - Preserving the original payload
In this example, you copy the original payload to a property using the Enrich mediator.
| Code Block | ||
|---|---|---|
| ||
<enrich>
<source clone="false" type="body"/>
<target action="replace" type="property" property="ORGINAL_PAYLOAD"/>
</enrich> |
Then whenever you need the original payload, you replace the message body with this property value using the Enrich mediator as follows:
| Code Block | ||
|---|---|---|
| ||
<enrich>
<source clone="false" type="property" property="ORIGINAL_PAYLOAD"/>
<target action="replace" type="body"/>
</enrich> |
