XUpdate problem when using namespaces.

Hi

I created two documents under collection /db/Configuration. One with namespace and the other without namespace. Xupdate works for the document without namespace but doesn't work for document with namespace

Document without namespace
<RunNum>
<currentRun>1</currentRun>
</RunNum>

Xupdate
<xu:modifications version="1.0"         xmlns:xu="http://www.xmldb.org/xupdate">
    <xu:update select=/RunNum/currentRun> 4 </xu:update>
</xu:modifications>

The above xupdate worked


Document with namespace
<prA:RunNum xmlns:prA="http://www.partsriver.com/ProAnalyze">
<prA:currentRun>1</prA:currentRun>
</prA:RunNum>

XUpdate
<xu:modifications version="1.0"         xmlns:xu="http://www.xmldb.org/xupdate">
    <xu:update select=/prA:RunNum/prA:currentRun> 4 </xu:update>
</xu:modifications>
The above xupdate didn't work.

Any clues towards solving this issue are welcome

Hi Tom
Thanks for your response. I added the namespace to <xu:modifications> tag
and the update started working.
<xu:modifications version="1.0"
     xmlns:xu="http://www.xmldb.org/xupdate"
     xmlns:prA="http://www.partsriver.com/ProAnalyze">
 <xu:update select=/prA:RunNum/prA:currentRun> 4 </xu:update>
 </xu:modifications>

I wanted to try out your second suggestion setting the namespace thru
XUpdateQueryService. But that is not working. I am gettting APIException
I have removed namespace declarations from the <xu:modifications> tag.
         String xupdate = "<xu:modifications version=\"1.0\">" +
             "   <xu:update
select=\"/prA:RunNum/prA:currentRun\">4</xu:update>"
            </xu:modifications>";
         XUpdateQueryServiceImpl service =
            (XUpdateQueryServiceImpl) col.getService("XUpdateQueryService",
"1.0");
          service.clearNamespaces();
         service.setNamespace(
"prA","\"http://www.partsriver.com/ProAnalyze\"" );
         service.setNamespace("xu", "\"http://www.xmldb.org/xupdate\"");
         long count = service.update(xupdate);
Any pointers towards problems in the code block would be useful

Thanks
Satish

 From what it looks like, you're just referring to prefixes in the
XUpdate query, which are insufficient  as they have no meaning unless
bound to a namespace.  So the namespaces have to be declared in the
XUpdate query as well, or possibly as part of a namespace mapping in
the XUpdateQueryService.
