Exception handling: Processor and Spring DSL

[Samuel Cox]

Hi,

I'm trying to define a route specific exception handling mechanism.
It's purpose is to apply a custom format to the response body of an
HTTP response.  My route is:

   <camel:route id="my-servlet">
      <camel:from
uri="servlet:///?servletName=diAdapterServlet&amp;matchOnUriPrefix=true&amp;disableStreamCache=true"/>
      <camel:onException>
        <camel:exception>java.lang.Exception</camel:exception>
        <camel:redeliveryPolicy maximumRedeliveries="0"/>
        <camel:handled>
          <camel:constant>true</camel:constant>
        </camel:handled>
        <camel:to uri="exceptionHandlingProcessor"/>
      </camel:onException>
      <camel:to  uri="httpInboundLoggingProcessor"/>
      <camel:to uri="httpToServicesProcessor"/>
      <camel:to uri="httpOutboundLoggingProcessor"/>
    </camel:route>
  </camel:camelContext>


Exception Handler is defined like so:

public class ExceptionHandlingProcessor implements Processor {
    public void process(Exchange exchange) throws Exception {
        System.out.println("hi from error!");
    }
}

Nothing appears to go through that handler though.  Any ideas on what
I'm doing wrong would be greatly appreciated.
