is it possible configure a channel with two or more packager?

[Jaime Vizán González]

Hi,

I have to get two kind of ISO message and both of them must be
processed. I have been reading JPosGuide about filter but I don´t
believe that it is the solution. is it necessary I develop a custom
channel?

Thanks in advance

I mean, is it possible configure a channel with one or more packager-
config property?

Not as things stand.

You would also need to configure the selection trigger - for one
packager or the other.

Out of interest, how would you know which message type arrived - so you
could steer the packager choice

The two kinds of messages have the same header but their body is
completely different. Inside the header, the type of message is
informed in a concrete bit. Is it possible to make a ISOMsg in two
steps? First, I could read the header with a heading packager. When i
have the type bit I could read the body with the appropriate packager.

Please have a look at BaseChannel's getDynamicPackager method.

You can create a channel that could override that method and figure out what packager to use depending on the message content.

Hope that helps.

Hi, Alejandro. I have created a new channel which extends ASCIIChannel
and I have redefined the getDynamicPackager (byte[] image) method but
I have found a new problem, in the image argument isn´t the header.
Only, in the image argument is the body.

[Alejandro Revilla]

Good point. I think we need to change the signature of getDynamicPackager(byte[] image) to something like
getDynamicPackager(byte[] header, byte[] image).

Would that work for you?

Jaime,

I went ahead and added a protected ISOPackager getDynamicPackager
(byte[] header, byte[] image) in r2791.

Hope this helps.

Are you using jPOS or jPOS-EE?

If you're using jPOS-EE just let me know and I can update the modules/
jpos/lib/jpos.jar with the new version, otherwise I'll wait for more
changes.

[Jaime Vizán González]

Ok, Im using JPOs.
Thanks

Ok, so Alejandro's change should really help you get to your goal.

I have (just - r2793) committed a small change to ensure the receive
method uses the new getDynamicPackager(header, image) method. The base
implementation of which calls the previous version to provide backward
compatibility.

Hey Mark, thank you for r2793, I neglected to add the most important part of the patch!
