Clone Mediator endpoint
I have to specify a "to" address of a clone mediator, but I need to do it
dynamically so I thought that :
<clone>
<target endpoint="endpoint/dynamic_endpoint.xml">
<sequence>...
should do the trick, but I am getting an exception when trying to <send />
in the clone mediator, how can I set the endpoint of the clone mediator so
that it points to an external endpoint file.
I should also mention that I am using other <endpoint
key="endpoint/other_dynamic_endpoint.xml"/> endpoints just fine so it's not
the endpoints xml files.

Thank you for your reply, unfortunately I had to switch to a more pressing
project, so it will be some time before I have a chance to test this.
Thank you,
Florin

Re: Clone Mediator endpoint

Yes, Hiranya is correct on this...
The clone mediator target mediates the message using the specified sequence
and then send the message using the specified endpoint.
So you shouldn't try to send the message in the target sequence.

Looking at the source code of the CloneMediator and the Target class, I
can't see why this approach doesn't work. It should work without any issues.
Here's the relevant code segment from the Taget class.
*if (sequence != null) {
synCtx.getEnvironment().injectAsync(synCtx, sequence);
} else if (sequenceRef != null) {
SequenceMediator refSequence = (SequenceMediator)
synCtx.getSequence(sequenceRef);
if (refSequence != null) {
synCtx.getEnvironment().injectAsync(synCtx, refSequence);
}
} else if (endpoint != null) {
endpoint.send(synCtx);
} else if (endpointRef != null) {
Endpoint epr =
synCtx.getConfiguration().getEndpoint(endpointRef);
if (epr != null) {
epr.send(synCtx);
}
}*
Can you please verify that Synapse doesn't send any messages to the endpoint
you have specified? Note that when an endpoint is refered by the target it
tries to send the message to that endpoint. Therefore putting a send
mediator in the clone mediator target is not required and that could even
cause issues. May be the clone mediator actually sends messages to the
specified endpoint and what is failing is the send mediator which tries to
send the message to the 'To' address set in the message.
Thanks,
Hiranya

The Error I am getting is :
2009-10-20 00:33:50,308 [10.9.4.40-Florin-9Aug2009] [SynapseWorker-1] ERROR
ClientUtils The system cannot infer the transport information from the

Axis2Sender Unexpected error during sending message out
org.apache.axis2.AxisFault: The system cannot infer the transport
information from the /services/Event URL.
which I don't get if I set the "to" attribute on the target element.
Re: Clone Mediator endpoint

Your approach seems to be correct and it should work, can you please attach
the error log that you are getting with this configuration?
Also do you have the registry declaration in the synapse.xml, I assume yes,
since you have other dynamic endpoints working. You may also attach the
synapse.xml configuration so that I can reproduce the issue if there are
any.
Thanks,
Ruwan
