How to process the response in Camel
Hi all,
I want to make a Camel base engine that adapts web services requests and
replies
For example :
- convert currencies from dollars to euro in both requests and responses
- The client understands Dollars
- The server understands euros.
I have the following route
<endpoint id="httpEndpointBackend"
uri="http://myEuropeanServer.com/myservice"/>
<route>
<from uri="direct:myServletServiceUri" /> <!-- called by a servlet doGt
and doPost methods-->
<process ref="myProcessor" />
<to ref="httpEndpointBackend" />
</route>
In my servlet, I extract http headers and body, send them to by endpoint
using
result = camelProducerTemplate.sendBodyAndHeaders(endPointUri,
httpBodyString, exchangeMapHeaders);
With this configuration, I can successfully process the request but I cannot
process the response.
I think it because processors are asynchonous but my process is
synchronous.
Is there a way to either
- use processors in a synchronous way (like servlet filters chain)
or
- define a processor that will be called once the http endpoint receives
its http response
Thanks
Guillaume

You could use the camel-jetty component to handle the request and send
the response back. Here is a unit test[1] of camel-jetty component to
show that.

Hi,
Thanks for your fast and helpful support Claus. It really helped me.
This is the solution you give me by mail... and may help someone else :

Hi
You can not add the exchange pattern in the URI. (only in the JBI component)
I think we need a clean mail. Could you post the entire route and relevant code. It should really be possible to extract the OUT and return it to the original caller.
PS: In your processor you could also replace the original IN body with the response from the webservice call. Then you can still use a In-Only pattern.

Please have a look at my previous reply, I've updated it : I added the
exchange format in the endpoint uri.
There are no changes.
May be the method ProducerCache.sendExchange() should be modified :
protected E sendExchange(Endpoint<E> endpoint, Producer<E> producer,
Processor processor, E exchange) throws Exception {
processor.process(exchange);
// now lets dispatch
if (LOG.isDebugEnabled()) {

return exchange;

Hi
You can change the MEP pattern at runtime by using this workaround
You can cast to DefaultExchange where there is a setter to set the pattern
DefaultExchange ex = (DefaultExchange) exchange
Ex.setPattern(ExchangePattern.InOut);

Hi
Ah there might miss a method for the multiple headers,
Do you mind creating a ticket in the bug tracker for this issue. Then I will make sure it's added.
There is a link to the tracker from here:
http://activemq.apache.org/camel/support.html
Is there a sendXXX method that accepts an exchange pattern and also the headers? If there is you can use that on.
Otherwise you can use the generic send(Exchange) where you can create the exchange and set all the stuff manually.
Check out the source code in DefaultProducerTemplate.java that can give you hints as well.

The only method requestXXX that exist is with a single hearder (no s at the
end of the method)
Object requestBodyAndHeader(String endpointUri, Object body, String
header, Object headerValue);
And I want to add all http headers in order to rebuild the same http request
to my "european server".
requestBodyAndHeader calls sendBodyAndHeader. For sendXXX, there are
Object sendBodyAndHeader(String endpoint,
ExchangePattern pattern,
final Object body,
final String header,
and
Object sendBodyAndHeaders(String endpointUri,
final Object body,
final Map<String, Object>
headers)
Using the problem using sendBodyAndHeaders is I cannot set the
ExchangePattern to InOut.
Your are right, running in debug mode, I see that the exchange pattern
associated to the endpoint is InOnly.
==> Is there a way to specify the Exchange pattern in another way (via the
endpoint uri like dataformat?, pring property)
But I don't know if the problem is here. In my servlet, I am able to process
the Exchange;
getOut() and put it in the httpResponse.getOutputStream()
result = camelProducerTemplate.sendBodyAndHeaders(endPointUri,
buff.toString(),
exchangeMapHeaders);
InputStream isResult = (InputStream)result;
final OutputStream respOs;
respOs = httpResponse.getOutputStream();
while (isResult.available() != 0) {
final int readByte = isResult.read();
respOs.write(readByte);
}
My Problem is that, in that case, I cannot process the response stream. In
my example, the client will receive prices in euros instead of in dollars.
So, I think my problem is to insert a processor to process the reply.!!!

Hi
If there is still an issue and you don't mind then you could create a .zip of your sample project to let me look into.
Or post the full snippets of the configuration and code so I will be able better to see the "full picture".
The exchange pattern stuff is on the roadmap for Camel 2.0 to be improved.

My Problem is that, in that case, I cannot process the response stream. In
my example, the client will receive prices in euros instead of in dollars.
So, I think my problem is to insert a processor to process the reply.!!!

Subject: How to process the response in Camel
Hi all,
I want to make a Camel base engine that adapts web services requests and
replies
For example :
- convert currencies from dollars to euro in both requests and responses
- The client understands Dollars
- The server understands euros.
I have the following route
<endpoint id="httpEndpointBackend"
uri="http://myEuropeanServer.com/myservice"/>
<route>
<from uri="direct:myServletServiceUri" /> <!-- called by a servlet doGt
and doPost methods-->
<process ref="myProcessor" />
<to ref="httpEndpointBackend" />
</route>
In my servlet, I extract http headers and body, send them to by endpoint
using
result = camelProducerTemplate.sendBodyAndHeaders(endPointUri,
httpBodyString, exchangeMapHeaders);
With this configuration, I can successfully process the request but I cannot
process the response.
I think it because processors are asynchonous but my process is
synchronous.
Is there a way to either
- use processors in a synchronous way (like servlet filters chain)
or
- define a processor that will be called once the http endpoint receives
its http response
Thanks
Guillaume

RE: How to process the response in Camel
Posted by Claus Ibsen <ci...@silverbullet.dk>.
Hi
Ah that is a little pitfall with the producerTemplate as it has many methods.
http://activemq.apache.org/camel/producertemplate.html
You should use sendXXX for IN only message exchange patterns
You should use requestXXX for IN-OUT message exchange patterns
So you should use requestBody:
result = camelProducerTemplate.requestBodyAndHeaders(endPointUri,
httpBodyString, exchangeMapHeaders);
What is the content on endPointUri? Do you send it the direct or the http endpoint?
