Document update with DocumentDefinition not working

Question

Hi
I would like to be able to update a PublicObject with new attributes and also reset the class name to which the object belongs.
I have written a small test program (see below) which compiles fine and, according to the APIs should work updating a PublicObject.
(Note that I haven't included the lines where I create a LibraryService and librarySession, but I am doing all that in an earlier part of the code. As input parameters (apart from username and pasword to start the session) I am supplying a path and filename for an existing document in IFS for which I want to do the update.)
Here is the code (note everything below is between try {  } catch { } statements but this is not shown here):
// First I set the Folder Object to the location the PublicObject resides in, then cast a Document Object from the existing file, where m_session is my librarysession.
FolderPathResolver fpr = new FolderPathResolver(m_session);
fpr.setRelativePath(destinationpath);
Folder f = fpr.getCurrentDirectory();
Document currentDoc = (Document) f.findPublicObjectByPath(filename);
// Now I am creating a DocumentDefinition, set the class and an attribute and try to update the document with these new values. The class METADATA exists and is a subclass of DOCUMENT.
String description = "This is a new description";
DocumentDefinition newDocDef = new DocumentDefinition(m_session);
newDocDef.setClassname("METADATA");
newDocDef.setAttribute("DESCRIPTION",AttributeValue.newAttributeValue(description));
currentDoc.update(newDocDef);
When I run this, nothing happens, i.e. the file in question retains its old class association and the description is not changed.
It would be greatly appreciated if someone could help and point out what is wrong with my code as having the ability to update documents is central to what we want to do.
Thanks very much.

I had the same problem and solved it by doing this 2 stepa:
1. Run report CRMOST_CREATE_PACKAGE, because after upgrade, package $WS_BOL_GEN is missing.
2. Run report CRMOST_GENERATION to generate webservice again.
