Making jpos client alive everytime

[Madan KC]

I have to restart the code everyday to connect to the server due to timeout.  Is there any way we can dynamically do echo testing so the system will be alive.

[Alejandro Revilla]

That's what the ChannelAdaptor component does. It reconnects automatically.

Are you using it?

It highly depends on your implementation, by default the jPOS channel adaptor will autoreconnect, so restarting it wouldn’t be needed, so I wonder, how’s your setup?

Anyway, you still don’t want to be reconnecting, so you need echoes, for that you can use a LogonManager.

The question is what is VTS doing.

That is providing the ticket your Channel connects to.

Do you have anything responding to 0800 from VTS not shown, you will need something otherwise, and perhaps to produce 0800 into VTS too, check its documented needs and status when things 'stop working'.

Either you know its working or it isn't.

If your VTS sends messages your jpos app should be able to receive and parse the message and match fields and data to what was sent.

If you are sending messages to VTS your VTS can validate if it's received the message you sent and match the content.

You can always use wireshark like utility to sniff the tcp traffic.

Or write a custom channel that dumps data it receives and sends in hex.

VTS will have its own log of hexdumps.

The channel you are using appears to be correct.

In VTS make sure to add the 2 byte length header config, I don't recall where it is as I haven't used the sim in ages.

Ok, thanks for sharing that detail, so it was VTS and not jPos giving up
on the conversation.
