Synapse endpoint timeout

Hi,
I'm trying out the <timeout> element functionality available for the various endpoints in Synapse and am having some difficulty getting it to work. Basically I have a synapse proxy service with definition as shown below and am forwarding the request to the SimpleStockQuoteService which responds after 20 secs (using thread.sleep), but since the endpoint timeout value is set to 3secs, it should timeout sooner and return a fault ...but I'm getting an error. 
Is there an example of how to get this working? 
Thanks
Murali

Re: Synapse endpoint timeout

Posted by Ruwan Linton <ru...@gmail.com>.
You need to send the message with a send mediator after removing the To
header with a header mediator in the fault sequence to send the fault back
to client.

Thanks,
Ruwan

Re: Synapse endpoint timeout

Posted by Murali Krishnan <cm...@yahoo.com>.
Thanks for the tip, Ruwan.
After including a log mediator with "full" level, I don't see this error anymore. But, the fault response doesn't come back to the client as well. Eventually, the client reports a "read timed out" socket exception...
Any idea why this may be happening? 
Thanks again
Murali

You could get rid of this issue, if you put a log mediator with full log

Hi Murali

What is the synapse version you are using. This is happened when try

message has not been built.

Please refer [1]

Thanks

Re: Synapse endpoint timeout

Posted by indika kumara <in...@gmail.com>.
Hi Murali

What is the synapse version you are using. This is happened when try
to use stream that has already been consumed. This is happened if the
message has not been built.

Please refer [1]

Thanks

Re: Synapse endpoint timeout

Posted by Murali Krishnan <cm...@yahoo.com>.
Thanks for the reply, indika. I think I made a small progress by removing the 'To' header in the fault sequence, but am encountering a different exception now somewhere within axiom... Any clues why this may be happening? Thanks.

Subject: Re: Synapse endpoint timeout

Hi

Error you have got is related with malformed endpoint URL.You can see
the timeout handler has done timeout processing.

BTW, before sending error back to client, remove existing ‘to’ header.
In your fault sequence, add ‘<header name="To" action="remove"/>’
before send mediator.

Thanks
Indika

Basically I have a synapse proxy service with definition as shown below and am forwarding the request to the SimpleStockQuoteService which responds after 20 secs (using thread.sleep), but since the endpoint timeout value is set to 3secs, it should timeout sooner and return a fault ...but I'm getting an error.
