can u please let me know where I am wrong..?

The input channel of your router is a QueueChannel and that is why you need poller configuration on your router. If you want a direct handoff, than remove the 'queue' subelement from your channel so it will become a DirectChannel.

Hi,

My coding of input channel is (that is named as output)

<int:channel id="output" >
<int:queue capacity="10"/>
</int:channel>

Now as u can see there is no queue sub element in my output named channel and also tell me how to make it as a DirectChannel. ..?

This is the queue sub-element...

Code:

---

<int:queue capacity="10"/>

---

Remove it to make it direct, or add a <poller default="true".../> element to poll for messages in the queue.

hi,

I have done that and thanks a lot, but after doing that i am still stuck up with this any error

Any idea what is going rite now..?

That means there is no element consuming the output channel.

You need to provide us with more of your configuration.

Hi,

but i have attached the header type router to the output channel, in other words whatever the outcome of the outer channel will be further consumed by the header type route and it will fillter on the bais of the incoming headers ...I am sending u the xml code generated by STS.....

Have a look at it...and plz let me know where I went wrong....!!!

Any idea of this prblm...?

Please do not repeat your own post here.

If this is the full configuration, it looks like you have no subscribers on either the 'inventory' or 'price' channels.

How to make subscribers for these two channels then...?
