[mule-user] XSLT transformation problem

[Chathura Ekanayake]

Hi,

I am trying to use Mule for transforming request messages before sending to a backend server and then
to transform back the responses before sending to the client.

Below is the model part of my configuration:

<model name="MyMuleModel">
        <mule-descriptor name="MyMule" implementation="org.mule.components.simple.BridgeComponent">
            <inbound-router>
                <endpoint address="http://localhost:8090/services" transformers="Xsltin" responseTransformers="Xsltout" synchronous="true"/>
            </inbound-router>
            <outbound-router>
                <router className="org.mule.routing.outbound.OutboundPassThroughRouter">
                    <endpoint address=" http://localhost:9000/soap/SimpleStockQuoteService"/>
                </router>
            </outbound-router>
        </mule-descriptor>
   </model>

When I am testing this, an exception occurs for every other message. (i.e. first message gets the correct response and the second message fails)
It is appreciated if someone can explain what is going wrong here and direct me to avoid this.

The error printed in the Mule console for failed messages is shown below:

Try using ChainedRouter in synchronous mode with a single endpoint instead.

Hi Andrew,

I tried this with org.mule.routing.outbound.ChainingRouter as you have mentioned, but still getting the same error.
Is there any other way to get this working?
