I'm just starting to explore SB.  I've tried a couple of sample scripts that
I've found in various tutorials, but having no luck.  Following is the
simplest one I've tried.  All steps run just fine, but message appears in
the RECEIVE section.

Additional notes:  tried on two different SQL 2005 servers.  Both running in
a named instance - is there any additional configuration required for this?

Thanks in advance.

Sample code follows.

create database TestSB
go
USE TestSB
GO
-- First, we need to create a message type. Note that our message type is
-- very simple and allowed any type of content
CREATE MESSAGE TYPE HelloMessage
VALIDATION = NONE
GO
-- Once the message type has been created, we need to create a contract
-- that specifies who can send what types of messages
CREATE CONTRACT HelloContract
(HelloMessage SENT BY INITIATOR)
GO
-- The communication is between two endpoints. Thus, we need two queues to
-- hold messages
CREATE QUEUE SenderQueue

CREATE QUEUE ReceiverQueue
GO
-- Create the required services and bind them to be above created queues
CREATE SERVICE Sender
 ON QUEUE SenderQueue

CREATE SERVICE Receiver
 ON QUEUE ReceiverQueue (HelloContract)
GO
-- At this point, we can begin the conversation between the two services by
-- sending messages
DECLARE @conversationHandle UNIQUEIDENTIFIER
DECLARE @message NVARCHAR(100)

BEGIN
 BEGIN TRANSACTION;
 BEGIN DIALOG @conversationHandle
       FROM SERVICE Sender
       TO SERVICE 'Receiver'
       ON CONTRACT HelloContract
 -- Send a message on the conversation
 SET @message = N'Hello, World';
 SEND  ON CONVERSATION @conversationHandle
       MESSAGE TYPE HelloMessage (@message)
 COMMIT TRANSACTION
END
GO
-- Receive a message from the queue
RECEIVE CONVERT(NVARCHAR(max), message_body) AS message
FROM ReceiverQueue
-- Cleanup
DROP SERVICE Sender
DROP SERVICE Receiver
DROP QUEUE SenderQueue
DROP QUEUE ReceiverQueue
DROP CONTRACT HelloContract
DROP MESSAGE TYPE HelloMessage
GO
