here is my client code:
MuleClient client = new MuleClient();
UMOMessage message = client.send("vm://input", new String("Something"),
null);
System.out.println(message.getPayloadAsString());
here is the mule-descriptor config:
<mule-descriptor name="Sample"
implementation="org.mule.components.simple.BridgeComponent">
<inbound-router>
<endpoint address="vm://input" synchronous="true"/>
</inbound-router>
<outbound-router>
<router
className="org.mule.routing.outbound.OutboundPassThroughRouter">
<endpoint
address="axis:http://localhost:8081/services/helloDescriptor?method=sayHello"
>
<properties>
<property name="style" value="document"/>
<property name="use" value="Literal"/>
<map name="soapMethods">
<list
name="qname{sayHello:http://helloworld.myservices.mule}">
<entry value="in0;string;in"/>
<entry value="sayHelloReturn;string;out"/>
</list>
</map>
</properties>
</endpoint>
</router>
