Help! Problem of XUpdate(Xindice)

[Ren Ziheng]

Hi,

i have already found a xindice based java gui. but it appears always a big problem from the xupdate functions. If i tip some commands in and try to execute them, it will appear an exception, this result from the example http://xml.apache.org/xindice/guide-developer.html#N1025F are extraordinarily similar:
*********************** Exception ************************ org.apache.xindice.client.corba.db.APIException:
IDLrg/apache/xindice/client/corba/db/APIException:1.0 at org.apache.xindice.client.corba.db.APIExceptionHelper.read(APIExceptionHelpe r.java:112) at org.apache.xindice.client.corba.db._CollectionStub.queryCollection(_Collecti onStub.java:833) at org.apache.xindice.client.xmldb.services.XUpdateQueryServiceImpl.updateResul t(XUpdateQueryServiceImpl.java:165) at org.apache.xindice.client.xmldb.services.XUpdateQueryServiceImpl.update(XUpd ateQueryServiceImpl.java:185) at XUpdate.main(XUpdate.java:41)
XMLB Exception occured 1 Query Processing Error

******************** Source Code ************************** import org.xmldb.api.base.*; import org.xmldb.api.modules.*; import org.xmldb.api.*;

public class XUpdate {
public static void main(String args) throws Exception { Collection col = null; try { String driver = "org.apache.xindice.client.xmldb.DatabaseImpl"; Class c = Class.forName(driver);

Database database = (Database) c.newInstance;
DatabaseManager.registerDatabase(database);
col =

DatabaseManager.getCollection("xmldb:xindice:///db/addressbook");

String xupdate = "<xu:modifications version=\"1.0\"" +
" xmlns:xu=\"http://www.xmldb.org/xupdate\">" + " <xu:remove select=\"/person/phone[@type = 'home']\"/>" + " <xu:update select=\"/person/phone[@type = 'work']\">" + " 480-300-3003" + " </xu:update>" + "</xu:modifications>";

XUpdateQueryService service =
(XUpdateQueryService) col.getService("XUpdateQueryService", "1.0"); service.update(xupdate); } catch (XMLDBException e) { System.err.println("XMLB Exception occured " + e.errorCode + " " + e.getMessage); } finally { if (col != null) { col.close; } } } }

******************* Baum Struktur ************************ db

i have also tested another gui(from
http://titanium.dstc.edu.au/xml/xmldbgui/screenshots.shtml) in different versions of jre. but it appears the same problem. i'm not sure, whether it's my problem or has xindice made sth wrong...

Thank you for your friendly help.
