One thing that i regret about SQLXML object, is that you can't do at the same time :
1) get an SQLXML Object from a resultset
2) modify It
3) update the SQLXML Object to the resultset
4) updaterow
I've tried this :
but it doesn't work.
If someone is interesting about getting data and updating data in xml.
my method is to get a string from my xml.
parse it
modify the data
and :
SQLXML sqlxml = con.createSQLXML();
DOMResult domResult=sqlxml.setResult(DOMResult.class)
domResult.setNode(xmldocumentDOM);
stmt.setSQLXML(1, sqlxml);
stmt.execute();
It's work .... but it's not beautiful ......
anyway, thank for the help !

I've tried this :
// retrieve an SQLXML object from the ResultSet:
SQLXML sqlxml = resultSet.getSQLXML(1); // 1 is the column index
// obtain DOM tree from SQLXML object:
DOMSource source = sqlxml.getSource(DOMSource.class);
// create document object from DOMSource:
Document document = (Document) source.getNode();
modify the document here
resultSet.setSQLXML(1,sqlxml );
resultSet.updaterow();
SQLXML sqlxml = resultSet.getSQLXML(1); // 1 is the column index
// obtain DOM tree from SQLXML object:
DOMSource source = sqlxml.getSource(DOMSource.class);
// create document object from DOMSource:
Document document = (Document) source.getNode();
modify the document here
resultSet.setSQLXML(1,sqlxml );
resultSet.updaterow();
but it doesn't work.

Your sample code and stacktrace don't seem to match, but I see what the problem is. The updatable ResultSet code isn't prepared for handling a SQLXML object. It's slightly tricky to fix because the code in question is in a JDBC2 class while SQLXML is JDBC4 only. I'll look into it.
