Content-Type is not supported in Camel DELETE method?

Question

How do i send content-type in Camel DELETE method. I have added the following way but It was not working correctly.

from("direct:start")
.setHeader(Exchange.HTTP_METHOD, simple("DELETE"))
.setHeader(Exchange.CONTENT_TYPE, simple("application/xml")) 
.setHeader(Exchange.HTTP_URI, simple("http://02.02.02.02:8080/rest/delete/student/688187"))
.to("http://emptyhost");

Could you please help me to resolve this issue?

Answer 1

As in a delete operation, no content is sent, the Exchange.CONTENT_TYPE property should not be needed.

Please, try

from("direct:start")
    .setHeader(Exchange.HTTP_METHOD, simple("DELETE"))
    .to("http://02.02.02.02:8080/rest/delete/student/688187");

or

from("direct:start")
    .to("restlet:http://02.02.02.02:8080/rest/delete/student/688187?restletMethod=delete");

By the way, using delete in the URL is not the RESTful way and should be ommited.

EDIT:

Camel does not transfer the body to the request of a DELETE operation, as can be seen digging into the source code. Use a PUT operation instead. See my answer to your other SO.
