xsd, unmarshal and getBody

Hi 

i doin't understand why it fail :
i have an xsd file
<?xml version="1.0" encoding="UTF-8"?>
<xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" >
	<xsd:complexType name="PersonType">
        <xsd:sequence>
            <xsd:element name="firstName" type="xsd:string"/>
            <xsd:element name="lastName" type="xsd:string"/>
        </xsd:sequence>
    </xsd:complexType>
    <xsd:element name="Person" type="PersonType"/>		

 			
		<xsd:complexType name="GreetingRequestType">
				<xsd:sequence>
					<xsd:element name="name" type="xsd:string" />
				</xsd:sequence>	
		</xsd:complexType>

	<xsd:element name="GreetingRequest" type="GreetingRequestType"/>		
	
	<xsd:complexType name="GreetingResponseType">
		<xsd:sequence>
			<xsd:element name="welcome" type="xsd:string" />
		</xsd:sequence>
	</xsd:complexType>
	<xsd:element name="GreetingResponse" type="GreetingResponseType"/>
</xsd:schema>


i use xjc to produce the java file


i have this route
	  <route>
	    <from
uri="restlet:http://127.0.0.1:9090/greeting?restletMethods=POST,GET"/>
	    	<unmarshal>
	    	        	<jaxb ignoreJAXBElement="false" prettyPrint="true"
contextPath="poc.camel.echange"/>
        	</unmarshal>

	    	<process ref="greeting"></process>
			<marshal>
            	<jaxb ignoreJAXBElement="false" prettyPrint="true"
contextPath="poc.camel.echange" />
        	</marshal>
	  </route>

This process failed
   public void process(Exchange exchange) throws Exception {
      GreetingRequestType user = (GreetingRequestType)
exchange.getIn().getBody(GreetingRequestType.class);


// 

        GreetingResponseType gr = new GreetingResponseType();
         gr.setWelcome(user.getName());
        exchange.getOut().setBody( gr );
}

the user is always nill, how to retrieve the instance ? (present in the
echange value see in debug mode)


but not this one
   public void process(Exchange exchange) throws Exception {
// nothing
    }
the incoming request is well unmarshall and marshall in the response
why ?


Thx
Bruno

Can you take a look at the camel jaxb unit tests[1]?
I don't how can you set the response object by change the greeting 
processor to be empty process.

BTW, you didn't mention the camel version.
