Characters inserted into XML returned by my web service

All,

Thank you.

All,

I'm having a small problem with returning XML from my pipeline definition. The returned XML seems to have some data inserted into it ('true' and '404' before my root element, marked bold):

<?xml version="1.0" encoding="utf-8"?>true
404
<io>
    <article source="smith" sourceid="$id" type="tmglstory">
    <section name="travel"/>
    <field name="headline">Baglioni Hotel</field>
    ...snip...
</io>

I've also been trying to debug this using ' debug="..." ' in my XPL file, but I'm unable to generate any log output (I'm checking ops.log and catalina.out. Please find my Log4J config attached). What's the trick to finding the debug output from my XPL debug directive? I must be missing something basic...

Here is my page-flow.xml:

<config xmlns="http://www.orbeon.com/oxf/controller">
    <page path-info="/smith/" view="smith.xpl"/>
    <epilogue url="oxf:/config/epilogue.xpl"

/>
</config>

Note that ' view="smith.xpl" ', as we are returning some XML here (using 'model=' instead of 'view=', allows you to have no output param defined in your XPL).

And here is my pipeline definition:

<p:config xmlns:p="http://www.orbeon.com/oxf/pipeline"
    xmlns:oxf="http://www.orbeon.com/oxf/processors"
    xmlns:xs="http://www.w3.org/2001/XMLSchema"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:xforms="http://www.w3.org/2002/xforms">

    <!-- p:param name="instance" type="input"/ -->
    <p:param name="data" type="output"/>

    <!-- Read in the stylesheet definition -->
    <p:processor name="oxf:url-generator">
        <p:input name="config">
            <config>
                <url>transform.xsl</url>
                <content-type>text/xml</content-type>
                <validating>false</validating>
                <handle-xinclude>false</handle-xinclude>
            </config>
        </p:input>
        <p:output name="data" id="firstXslt" />
    </p:processor>  
   
    <!-- Read in the source XML -->
    <p:processor name="oxf:url-generator">
        <p:input name="config">
            <config>
                <url>smith.hotels.xml</url>
                <content-type>text/xml</content-type>
                <validating>false</validating>
                <handle-xinclude>false</handle-xinclude>
            </config>
        </p:input>
        <p:output name="data" id="smithXml" />
    </p:processor>    
   
    <!-- Create the Escenic format: Apply the stylesheet to the source xml  -->
    <p:processor name="oxf:xslt">
        <p:input name="data" href="#smithXml" />
        <p:input name="config" href="#firstXslt" />
        <p:output name="data" id="escenicXml" />
    </p:processor>

   
    <!-- Wired off, just send the transformed XML back to the client for now (using the identity processor below) -->
    <!-- Call the REST webservice -->
    <!--p:processor name="oxf:xforms-submission">
        <p:input name="submission">
            <xforms:submission method="put" action="http://localhost:8080/timmy/import"/>
        </p:input>
        <p:input name="request" href="#escenicXml" debug="escenicXml"/>
        <p:output name="response" ref="data" debug="response"/>
    </p:processor-->
  
   <!-- Just return the transformed XML to the user for now.
        Once we get this right, will send it to the webservice instead (see above) -->
    <p:processor name="oxf:identity">
        <p:input name="data" href="#escenicXml"/>
        <p:output name="data" ref="data"/>
    </p:processor>   

</p:config>

Please find a reproducible example attached. My system configuration:
- Apache Tomcat 5.5.26
- java version "1.5.0_13"
- orbeon-3.6.0.200806260137 nightly build
- OS X 10.4.11

Perhaps the problem lies with running the returned XML through 'oxf:/config/epilogue.xpl' ? I'm not sure. Has anyone else out there been able to configure Orbeon to return plain XML?

Any help would be very much appreciated. Many thanks!

Henrik
