[mule-user] muleClient as a webservices client ,if the transformer can't be use

[yu zhu]

I use mule publish a serviceComponent as a webservices，then use muleCient to call it. part configuration and part client code as follow:

<!-- a global custom transformer want to convert the request parameter into a javaBean -->
<custom-transformer name="convertParamToUser" class="com.mule.test.ConvertParamToObject"/>

<model name="axisTest">
<service name="echoService">

<inbound>
<axis:inbound-endpoint address="http://localhost:9900/services">
<transformer ref="convertParamToObject"/>
</axis:inbound-endpoint>

<!--responseTransformer-refs="convertUserToString" -->
</inbound>

<component class="com.mule.test.EchoServiceImpl"/>
</service>
</mode>

MuleClient client = new MuleClient()
MuleMessage message= client.send("axis:http://localhost:9900/services/echoService?method=print","aaa,ccc",null);

_________________________________________________

when I execute the client ,then throw exception,I want to know when i use muleClient as a webservices client to call mule's web services&#65292;if the transformer can't be use.

thanks!

My first suspicion is that you are overriding some transformers on the axis endpoint by adding your own. Any time you add a transformer to an endpoint, all other "standard" transformers are ignored. You must explicitly add those transformers back if your custom transformer does not do that functionality. Have you tried this without your transformer?
