[bdbxml] Document modifications are not applied

Hello,

I've got a problem with the modification of documents. I took the
modification example from sleepycat.com and
implemented an attribute value change as follows:


   
....             
try
{
   XmlModify BerkModifier = BerkManager.createModify();
   XmlQueryContext context = BerkManager.createQueryContext();

   XmlQueryExpression BerkQExp =
BerkManager.prepare("collection('xmachberk.dbxml')/kenndaten[@doc_id=d" + 
                    String.valueOf(intDocId) +
"]/felder_als_attribute/@double_feld_r", context);

   System.out.println("DEBUG Anfrage:
collection('xmachberk.dbxml')/kenndaten[@doc_id=d" + 
                    String.valueOf(intDocId) +
"]/felder_als_attribute/@double_feld_r");

   BerkModifier.addUpdateStep(BerkQExp, newAttributeValue );
  
   System.out.println("DEBUG retdoc: " + retDoc.getContentAsString());

   XmlDocument retDoc = BerkContainer.getDocument(docId);

   XmlValue docValue = new XmlValue(retDoc);
            
   System.out.println("DEBUG docValue asString: " + docValue.asString());
                        
   BerkModifier.execute( docValue, context, BerkUpdContext);
            
   XmlDocument retDoc2 = BerkContainer.getDocument(docId); // +
String.valueOf(intDocId));
            
   System.out.println("DEBUG docValue ret2: " +
retDoc2.getContentAsString());
 
   }

...


The problem is that the document will not be modified. The line 

System.out.println("DEBUG retdoc: " + retDoc.getContentAsString());

gives me the same output as 

System.out.println("DEBUG docValue ret2: " + retDoc2.getContentAsString());.

And a manual check with the console utility gives me of course the same
result.



Any help is highly appreciated.


Best regards,


Stephan Korthoff
