Re: recipientList with POST and request body
I added a line: template.start() before sending request, it did not help, got same exception. I changed to context.start() it did not work either. The code is within bean implementation, so context is build-in variable, and started already, why do I need to start it again? From other example code, the pattern to use it should be simple as 2 lines: def template = context.createProducerTemplate() def response = template.requestBodyAndHeaders(endpointUri, xbody, xheaders, java.lang.String.class) Can someone post working code to use producerTemplate to POST request? -- View this message in context: http://camel.465427.n5.nabble.com/recipientList-with-POST-and-request-body-tp5725142p5725283.html Sent from the Camel - Users mailing list archive at Nabble.com.

You just need to start the ProducerTemplate, you don't need to start the camel context as it is already started.

Re: recipientList with POST and request body
I think I understand now why I can't do this with producerTemplate: yes, there is intensive security checks for our web service site, at this point to use producerTemplate I already logged in and got session in previous steps in the same route, the problem is that the security token with session information is not passed to this site correctly since producerTemplate is passing simple body and headers without security tokens, that's why it failed. Do you have way to take tokens with the template? -- View this message in context: http://camel.465427.n5.nabble.com/recipientList-with-POST-and-request-body-tp5725142p5725300.html Sent from the Camel - Users mailing list archive at Nabble.com.
Re: recipientList with POST and request body
Willem,
Thanks, I read some of your posts in the past, they were very helpful. I
appreciate your advice.
My currently situation is: I used beans for complicated business logic, to
send different requests to different resources and to aggregate the results
in the past. But now our company is moving to cloud computing environment,
our platform (modified/enhanced camel environment) moved to cloud
environment. So Bean implementation is strongly discouraged since
(auto/versioned) bean deployment could be very complicated in the
environment.
I am moving to write all the code in groovy within the route instead of bean
as best practice in our group. ProducerTemplate could be good solution if
bean implementation is allowed. I tried a simple test by sending single
request in groovy(I need to aggregate the final response as part of
requirement, also I used setBody tag to cheat route to send request which
may not be best practice):
setBody
groovy
import org.apache.camel.ProducerTemplate
import org.apache.camel.impl.DefaultProducerTemplate
def template = context.createProducerTemplate()
def endpoint = myendpoint
def body = ${header.REST_REQUEST_BODY}
def headers = [Content-Type:application/json,
CamelHttpMethod:POST]
def response = template.requestBodyAndHeader(endpoint, body,
headers,
java.lang.String.class)
return response
/groovy
/setBody
I got expected exception: context is missing since context is NOT default
build-in variable. How do I get context in simple DSL, or how do I get a
producerTemplate without using context?
If not, is there other solutions/patterns that I can use for this situation
without using beans?
I am looking at [splitter][broadcast] pattern, but have not found way to
resolve it. Maybe this is too demanding for Camel without bean: dynamic URI
list, dynamic HTTP method(optional), dynamic request body(optional), and
aggregate all responses. I am using Spring DSL plus groovy only, java DSL is
not allowed.

Re: recipientList with POST and request body
I just checked the camel-script code, it will bind the camel context within the
script context.
But it should be more easy to write a custom bean[1] and inject the camel
context to it, then you can get full control of it.

recipientList with POST and request body
Hi,
I need to send request to a dynamically constructed URL list which provides
RESTful web services. So my simplest need is to send POST requests with
fixed JSON body, later I may need to construct different JSON body for each
URL in the list as well, and since it's RESTful service, DELETE/PUT are also
possible. how should I do it?
This is standard recipientList pattern from document:
route
from uri=direct:a /
recipientList delimiter=,
headermyHeader/header
/recipientList
/route
Should I do:
route
from uri=servlet:///sendToRecipients /
setHeader headerName=WEB_SERVICE_URLS
constantconstruct my urls here/constant
/setHeader
setHeader headerName=CamelHttpMethod
constantPOST/constant
/setHeader
setHeader headerName=Content-Type
constantapplication/json/constant
/setHeader
setBody
constant{name:fixed text}/constant
/setBody
recipientList delimiter=,
headerWEB_SERVICE_URLS/header
/recipientList
/route
Thanks for advice.

Re: recipientList with POST and request body
Hi,
I'm afraid the recipientList will not meet your needs at this time.
As you need to change the Http method and request JSON body dynamically,
current recipientList just supports to change the Camel Endpoint URI
dynamically.
So I suggest you to leverage the ProducerTemplate[1] in your customer bean, so
you can get full control of message header , body and the Camel Endpoint URI at
same time.
