URL: https://discuss.orbeon.com/RESTful-Web-Service-in-XPL-tp1049942.html

I am trying to expose a RESTful Web Service written in XPL and XQuery, but having some difficulties.

The service is called via a post and passing base64 encoded parameters. Receiving the parameters and turning them back into XML for processing by the XPL is throwing an error that I am not able to debug. Can anyone point out what I am doing incorrectly? All code below...



page-flow.xml

<page id="restcall" path-info="/service/xslt" default-submission="info.xml" model="processor.xpl">
   <setvalue ref="/submission/transform" parameter="transform"/>
   <setvalue ref="/submission/xmlContents" parameter="xmlContents"/>
</page>

info.xml

<submission xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:base64Binary" content-type="binary/octet-stream">
   <transform/>
   <xmlContents/>
</submission>

processor.xpl

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"
             xmlns:xs="http://www.w3.org/2001/XMLSchema"
             xmlns:oxf="http://www.orbeon.com/oxf/processors">

  <p:param type="input" name="instance" debug="input_instance"/>

  <p:processor name="oxf:to-xml-converter">
     <p:input name="data" href="#instance" debug="xml_input/>
     <p:input name="config"><config/></p:input>
     <p:output name="data" id="requestdata"></p:output>
  </p:processor>

 

</p:config>



Logs show output from debug statement = input_instance to be:

<submission xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xs="http://www.w3.org/2001/XMLSchema" xsi:type="xs:base64Binary" content-type="binary/octet-stream">
   <transform>mytransform.xsl</transform
   <xmlContents><data><descript>Description goes here</descript></data></xmlContents>
</submission>

Right after above output, the following error is thrown
