Re: passing the HTTPServletRequest from Jetty to a SEDA consumer in Spring DSL

[Willem Jiang]

Hi,

Can you try to set the ID into the message header instead of the message 
body ? In this way you can the Request object back :)

You bean's method could
public String controller(@Header("id")String body, Exchange exchange) ;

Hi,

Apologies, I didn't word my previous email very well; what I should have
also mentioned for clarity is that if I do this:

        <route>
            <from uri="jetty:http://0.0.0.0:8080/endpoint"/>
            <to uri="bean:myBean"/>
            <transform>
                <simple>${id}</simple>
            </transform>
        </route>

The same bean is able to obtain the HTTPServletRequest to get the POST data
(base64 encoded binary) andthe URL parameters,  however,  if I introduce the
SEDA
call the same bean can't get the HTTPServletRequest. The salient bean code
is:

 public String controller(String body, Exchange exchange) {

    try {
      HttpServletRequest req =
exchange.getIn().getBody(HttpServletRequest.class);

Hi,

I have a Jetty endpoint that when recieving a message will perform the
processing asynchronously and syncronously return a correlationId so the
client can come back later to another endpoint to see how processsing is
going.

I found an example on the mailing list of how to pass the HttpSession
object using Java, but I can't seem to find out how
to reference or pass the HttpRequest using SpringDSL.  What I have at the
moment is:


        <route>
            <from uri="jetty:http://0.0.0.0:8080/endpoint"/>
            <inOnly uri="seda:sendASync"/>
            <transform>
                <simple>${id}</simple>
            </transform>
        </route>

        <route>
            <from uri="seda:sendASync"/>
            <to uri="bean:myBean"/>
        </route>

Is there a way to say 'pass the HTTP stuff through please Mr SEDA'?
Should I really be setting a header property to that of a HTTP Object?  How
do I obtain it?
Should I architect this differently?

All the best,
Wayne
