xupdate

[jmt]

Trying to use xupdate, I get the following discrepancy :

This java code :

String xupdate="<xupdate:modifications version=\"1.0\" 
xmlns:xupdate=\"http://www.xmldb.org/xupdate\";>"+
                        "<xupdate:update select=\"/[EMAIL 
PROTECTED]'"+login+"']/name/title\">"+title+
                        "</xupdate:update>"+
                        "</xupdate:modifications>";

try{
XUpdateQueryService 
service=(XUpdateQueryService)usersCollection.getService("XUpdateQueryService","1.0");
                        service.update(xupdate);

etc.

produces the following error :

XUpdate error : Query error: java.lang.Exception: 
java.lang.NoClassDefFoundError: org/apache/xerces/framework/XMLParser

But this class is a feature from xerces-1, and xindice-1.1 is supposed to use 
xerces-2
