Servlet End-Point Route Processing in XML

I'd greatly appreciate help in converting the below route into its XML
equivalent.  I am stuck at the part on how to set the content type, charset
header and the body of the response itself.

Thanks...

from("servlet:///hello?matchOnUriPrefix=true").process(new Processor() {
    public void process(Exchange exchange) throws Exception {
        String contentType =
exchange.getIn().getHeader(Exchange.CONTENT_TYPE, String.class);
        String path = exchange.getIn().getHeader(Exchange.HTTP_PATH,
String.class);
        assertEquals("Get a wrong content type", CONTENT_TYPE, contentType);
        String charsetEncoding =
exchange.getIn().getHeader(Exchange.HTTP_CHARACTER_ENCODING, String.class);
        assertEquals("Get a wrong charset name", "UTF-8", charsetEncoding);
        exchange.getOut().setHeader(Exchange.CONTENT_TYPE, contentType + ";
charset=UTF-8");                        
        exchange.getOut().setHeader("PATH", path);
        exchange.getOut().setBody("Hello World");
    }
});

There is a setHeader tag. Which accepts an expression. So we can use
the simple language to concat a dynamic string.

 <setHeader name="Content-Type"><simple>${in.header.Content-Type};charset=UTF-8</simple></setHeader>

You can also just use the old java code and refer to it as a processor

<bean id="myProcessor" class="com.mycompany.MyProcessor"/>

<from xxxx/>
   <processRef ref="myProcessor"/>
   ...

And have a class

public class MyProcessor implements Processor {
   // implement the java code below that sets the headers
}
