Email UMS Adapter returning invalid attachments href code

Question

Hello,
Trying to process emails with the UMS Adapter I'm having a problem.
The href value that the attachments have are invalid. For instance:
<inputVariable>
  <part  name="body">
  <ns0:message>
  <payload  xsi:type="xs:string"> testing </payload>
  <attachment>
  <Attachment  href="1"/>
  <Attachment  href="2"/>
  <Attachment  href="3"/>
  </attachment>
  </ns0:message>
  </part>
</inputVariable>
It saw it was strange because on the samples I've found the href property is always a GUID or similar code.
I've tried to get the contents for any of the attachments but I'n getting the following error:
javax.xml.xpath.XPathExpressionException: Cannot load attachment with dbKey: 2
        at oracle.xml.xpath.JXPathExpression.evaluate(JXPathExpression.java:242)
        at com.collaxa.cube.xml.xpath.BPELXPathUtil.evaluate(BPELXPathUtil.java:247)
Does anyone know the reason for this? and how to solve it?
Thanks,
Daniel Alves

Answer 1

<copy> 
  <from expression="ora:getAttachmentContent('input','bin')"/>
  <to variable="initiateTaskInput" part="payload"
  query="/taskservice:initiateTask/task:task/task:attachment/task:content"/>
</copy>
Above will copy the Attachment content which has its HREF stored in "input/bin" variable to "content" variable in base64 encoded form.
Now you can view the attachment in BPEL flow trace and parse it using BPEL Assign/XSLT.
