Hi Paul,

Attaching the sources for your reference. It also includes a client
which sets the header to "application/xml". But, it does not fix it either.
The resource method is getting invoked. But, I always get the same
response as XML.

<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<rows>
<row>
<cell>&lt;div class=&quot;progressOuterRow&quot;&gt;&lt;div
class=&quot;progressInnerRow&quot; style=&quot;width:
25.0px;&quot;&gt;&lt;/div&gt;&lt;div
class=&quot;progressText&quot;&gt;25/100 MB&lt;/div&gt;&lt;/div&gt;</cell>
</row>
</rows>

Thanks!
Arul
