> My set-up is really simple:
> -----------------------
>        <proxy name="proxy" transports="http">
>            <target endpoint="jms_endpoint" />
>            <wsdl key="wsdl_with_one_way_op" />
>        </proxy>
> -----------------------
> The only special thing is that the operation defined in the WSDL and
> invoked by the client is one-way (an in-only MEP).
> I experience that a one-way message (to an in-only MEP) that is sent
> to a JMS destination via JMSSender causes JMSSender to wait for a
> response message on a reply
> queue. Of course this does not make sense, and indeed the blocking JMS
> receive of that reply message ultimately times out with this error:
> -----------------------
> DEBUG [13 Mar 20:33:13]  JMSSender - JMSSender invoke()
> DEBUG [13 Mar 20:33:13]  JMSSender - [Client]Sending message to
> destination : TOPIC.T_INT_CLIENT_EVT
> DEBUG [13 Mar 20:33:13]  JMSSender - Waiting for a maximum of 30000ms
> for a response message to destination : QUEUE.JMS_TQ3
>  WARN [13 Mar 20:33:43]  JMSSender - Did not receive a JMS response
> within 30000 ms to destination : TOPIC.T_INT_CLIENT_EVT
> -----------------------
> Very briefly looking at the code for
> org.apache.axis2.transport.jms.JMSSender in the trunk it indeed seems
> that JMSSender sets the flag "waitForResponse" to true regardless of
> whether the messages is one-way (to an in-only MEP) or not.

> The problem here is that you do not define to Synapse which operation to
> invoke with the WSDL, or if its IN only or IN-OUT. I guess we could
> specify this within the endpoint definition, or maybe even set the
> replyTo header to none to indicate that the message is not expecting a
> reply?

> Paul replied:
> ------------------------------
> As a post 1.0 we need to be able to read the WSDL definition and use
> that. In the meantime, I suggest we add an explicit marker to endpoint
> to indicate not to expect a response.
> I don't go for the none approach.... it seems counter-intuitive to me.
> That seems to be telling the target what to do, not Synapse.
