Error while creating the Ole Object (MSN Messenger)

Question

Hi,
We are trying to send a mail by invoking MSN Messenger. We have imported "Messenger.MsgrObject" OLE Object and written the following code to logon to the Messenger.
DECLARE
     MSGOBJ123 OLEOBJ;
     SRVOBJ123 OLEOBJ;
     SRVOBJ1234 OLEOBJ;
BEGIN
     MSGOBJ123 := CREATE_OLEOBJ('Messenger.MsgrObject');
-- Get all the services from the Messenger Object
     SRVOBJ123 := Messenger_IMsgrObject.Services(MSGOBJ123);
-- Get one of the services
     SRVOBJ1234 := Messenger_IMsgrServices.Item(SRVOBJ123, 0);
     IF :TXTUSR = NULL THEN
     MESSAGE('User Name cannot be null');
     RAISE FORM_TRIGGER_FAILURE;
     ELSIF :TXTPWD = NULL THEN
     MESSAGE('Password cannot be null');
     RAISE FORM_TRIGGER_FAILURE;
     ELSE
-- Log on to the Messenger By passing the MsgObject,
-- User Name, password, Service Object
     Messenger_IMsgrObject.LogOn(MSGOBJ123, :LOGINBLK.TXTUSR, :LOGINBLK.TXTPWD, SRVOBJ1234);
     END IF;
END;
We get this error while executing this program
"FRM-40735: WHEN-BUTTON-PRESSED trigger raised unhandled exception ORA-100504"
Please advice whether there is way to solve this problem or any other method of accessing MSN Messenger.
Thanks

Answer 1

do a check on the wsdl file and how you are passing values in the proxy. The tags for XML are not correct. Open the WSDL in IE and see there must be an error. Or probably when passing the actual values to the XML generated each element is not closed properly. Error says tags dont match.
