Hello,
When you use the method "updateResource("PO-NI-01", updateXml);" the
operation only concerns the document called PO-NI-01. I think this
document does not exist in your database.
When you test this line : ResourceSet resourceSet =
queryService.query(queryXml);. the operation concerns on the whole
collection.
To correct your program, you should use this method:
"updateService.*update*(updateXml);", because the operation concerns the
whole collection. Or you should check if the document "PO-NI-01" exists.
Tell me whether it helps you or not,
Yan.

Hello,
Im trying to execute a xupdate to change the value of an element in an
document.
String updateXml = "<xupdate:modifications version=\"1.0\""

select=\"/domain/[EMAIL PROTECTED]'PLAYOUT']/memberVariable[name='channel'] \">"

Collection collection = con.getCollection();
XUpdateQueryService updateService = (XUpdateQueryService)
collection.getService("XUpdateQueryService", "1.0");
updateService.updateResource("PO-NI-01", updateXml);

....................
From the client it appears as if the update is successfull! Ive tested the
select part of the xupdate query and it returns a document segement as
expected - I tested this with ....
Collection collection = con.getCollection();
XPathQueryService queryService = (XPathQueryService)
collection.getService("XPathQueryService", "1.0");
ResourceSet resourceSet = queryService.query(queryXml);
Any ideas on this matter are greatly appreciated, as it doesnt make sense to
me :)
Configuration: xindice 1.1b4, tomcat 5.0.30, jdk 1.5, os RH 9.0.
Regards,
Julie.
