deferred acknowledgment

[gcaruana]

Hi,

I would like to know if a channel can manage the "deferred acknowledgment".
For example:
For each Hl7 message received on inbound channel, mirth has to send back, on the same socket, a character (06), so the ancillary knows that mirth has securely stored the last message.

I know it's a strange request.

Do you think a right solution could be change something on mule ??

Please let me know

Re:deferred acknowledgment

This can be done using a TCP reader, in a synchronous channel.

Of course, you can modify the LLP reader to achieve this. In this case you need to modify the mirth code (not mule code).

Mirth 1.6 allows you to access the incoming socket directly on both TCP and LLP.

Re:deferred acknowledgment

Dear All,

thank you for your quick and detail answer to my question.
When do you plan to release the 1.6 ?

I tried to define a simple TCP Listener, but my ancillary system waits the following deferred ACK

0B 06 1C 0D

and i think the TCP listenr sends just the 06

Please, other proposal?

Thank you so much

Re:deferred acknowledgment

Dear All,

Can you explain better how to access sockets from transformer?

it could be the solution to my issue related to the deferred ack

Thank you

Re:deferred acknowledgment

You have an object called "receiverSocket"

This is a standard Java socket - please see http://java.sun.com/j2se/1.5.0/docs/...et/Socket.html for information on using it.

You can use any Java class from your transformer by using "Packages.<name of class>"

For example, to use an input stream:

var is = new Packages.java.io.InputStream;

You can also access the objects directly from the socket:

receiverSocket.getOutputStream().write(0);
receiverSocket.getOutputStream().write(6);
receiverSocket.getOutputStream().flush();

How to use "receiverSocket"?

I got the following error message when uisng "receiverSocket"
