Oracle Forms

Hello!

I'm trying to use OLE2 with forms 10g, and I'm getting these errors :

WUO-714 [OleFunctions.setExceptionValues()] Unable to get the last OLE Error details; Exception null
WUO-700 Unable to create the OLE Server {0}; Exception: {1}.

I use this code :

DECLARE
app CLIENT_OLE2.OBJ_TYPE;
docs CLIENT_OLE2.OBJ_TYPE;
doc CLIENT_OLE2.OBJ_TYPE;
selection CLIENT_OLE2.OBJ_TYPE;
args CLIENT_OLE2.LIST_TYPE;
BEGIN
-- create a new document
app := CLIENT_OLE2.CREATE_OBJ('Word.Application');
CLIENT_OLE2.SET_PROPERTY(app,'Visible',0);

docs := CLIENT_OLE2.GET_OBJ_PROPERTY(app, 'Documents');
doc := CLIENT_OLE2.INVOKE_OBJ(docs, 'add');

selection := CLIENT_OLE2.GET_OBJ_PROPERTY(app, 'Selection');

-- insert data into new document from long item
CLIENT_OLE2.SET_PROPERTY(selection, 'Text', :name.name);

-- save document as example.doc
args := CLIENT_OLE2.CREATE_ARGLIST;
CLIENT_OLE2.ADD_ARG(args, 'c:\example.doc');
CLIENT_OLE2.INVOKE(doc, 'SaveAs', args);
CLIENT_OLE2.DESTROY_ARGLIST(args);

-- close example.doc
args := CLIENT_OLE2.CREATE_ARGLIST;
CLIENT_OLE2.ADD_ARG(args, 0);
CLIENT_OLE2.INVOKE(doc, 'Close', args);
CLIENT_OLE2.DESTROY_ARGLIST(args);

CLIENT_OLE2.RELEASE_OBJ(selection);
CLIENT_OLE2.RELEASE_OBJ(doc);
CLIENT_OLE2.RELEASE_OBJ(docs);

-- exit MSWord
CLIENT_OLE2.INVOKE(app,'Quit');
END;

Somebody can help me please??!!
