Updating a documents Mime Type

Geoff_Price_(JTASCAdmin_(Delete)_1422989)

Has anyone used LAPI to update a documents Mime Type? I am using JAVA and LAPI to write a custom interface into Livelink. I allow users with correct permissions to update some of the metadata (Name, catalog, and comments). Works great! But, I also want to allow them to change the mime type of a document. Using the same kind of routine I'm using for updating Name, catalog and comments doesn't seem to work. Here is my code:

-----------------
// Have to call GetObjectInfo first for properly formatted Assoc for objectInfo
LLValue objectInfo = new LLValue();
doc.GetObjectInfo(volID, objID, objectInfo);
String obj_name = request.getParameter("objName");
String obj_desc = request.getParameter("comment");int catalog = Integer.parseInt(request.getParameter("catalog"));

objectInfo.setString("NAME", obj_name);
objectInfo.setString("Comment", obj_desc);
// Can only update catalog using an SQL query. Ughh!
PreparedStatement pstmt = db.prepareStatement("update dtree set catalog = ? where dataID = ?");
pstmt.setInt(1, catalog);
pstmt.setInt(2, objID);
int do_update = pstmt.executeUpdate();
doc.UpdateObjectInfo(volID, objID, objectInfo);

-----------------
That works great! Now, to update the mime type for a document, one would think you could do this...

// Have to call GetVersionInfo first for properly formatted Assoc for objectInfo
LLValue verInfo = new LLValue();
doc.GetVersiontInfo(volID, objID, 0, verInfo);
int docID = verInfo.toInteger("ID");
String mime_type = request.getParameter("mimetype");
verInfo.setString("MimeType", mime_type);
doc.UpdateVersionInfo(volID, docID, 0, verInfo)

But this just won't work for me for some reason. I get back an error that says "could not get results" when I catch the exception at UpdateVersionInfo. Can anyone provide any insight???
Thanks.

Message from Nair, Krishnankutty N. via eLinkLooking at the API docs I am not sure what is causing the error but whenever I have to use something and update I have used the LLValue objectin conjunction the Assoc object methods and properties.So I would tryto get the verInfo into an assoc and then manipulate it.The setstring returns LLValue verInfo = new LLValue.setAssoc();
//Your code for gtting mime typeverInfo.add("MimeType", mime_type);//sets the MimeTypedoc.UpdateVersionInfo(volID, docID, 0, verInfo)

Also I would examine the contents of the LLValue objectInfo = new LLValue();
doc.GetObjectInfo(volID, objID, objectInfo);
and see if the MimeType is a key in that assoc.Krishnankutty N NairConocoPhillips-----Original Message-----From: eLink Discussion: LAPI Discussion[mailto:lapi@elinkkc.opentext.com]Sent: Monday, April 26, 2004 1:04 PMTo: eLink RecipientSubject: Updating a documents Mime TypeUpdating a documents Mime TypePosted by Price, Geoff on 04/26/2004 02:00 PMHas anyone used LAPI to update a documents Mime Type?
