Jpos server disconnect intimation to JPOS client

[Amit Vadje]

Hi,

We have one async jpos client and jpos server program. Jpos client sends the request to server using QMUX in async manner. How can we identify whether request is sent successfully to server or not in JPOS client if JPOS server is not started/disconnected?
As we received response message as NULL in JPOS client for JPOS server timeout or disconnected/not started case.


Thanks,
Amit

You can call mux.isConnected() before trying. That works if you have set de ready property as in the next example borrowed from the excellent must read jpos programmer's guide:

<mux class="org.jpos.q2.iso.QMUX" logger="Q2" name="mymux">
 <in>your-channel-receive</in>                               (1)
 <out>your-channel-send</out>                                (2)
 <ready>your-channel.ready</ready>                           (3)
</mux>

(3) In order to provide a usable MUX.isConnected() method, the MUX needs to have a way to know if the underlying channel, loosely connected through the in/out queues is actually connected. The channel adaptor sets an entry in the space named after the channel’s name with the extension .ready as true when connected, so the optional ready element has to match that name. If a <ready> element isn’t present, MUX.isConnected() will always return true.

Hope this helps

Hi,

Hi Andres,

Thanks a lot. Using this setting we are able to verify the channel is connected or not.


Thanks,
