Error: HTTP method DELETE doesn't support output

[Akki]

I am trying to call the restful web service - delete method using the jersey
client (using following piece of code):

ClientResponse response = Client.create().resource(url).entity(mvp,
MediaType.APPLICATION_XML).delete(ClientResponse.class);

But, I am getting the error message:
com.sun.jersey.api.client.ClientHandlerException:
java.net.ProtocolException: HTTP method DELETE doesn't support output

Complete trace is given below.

Could you please let me know if this error is fixed OR is there any other
way in which I can make this call? I also tried calling it with
ApacheHttpClient but, as per my understanding it is used to make simple GET
and POST requests (not DELETE) to a Web resource.

Hi Akki,

This is a rather bizarre and pointless limitation in the
implementation in HttpURLConnection, and i have no idea why such a
limitation was implemented. Namely HttpURLConnection does not support
the sending of a request entity for a DELETE method.

Two possible solutions:

1) Use the Apache HTTP client integration, see:

https://jersey.dev.java.net/nonav/documentation/latest/user-guide.html
#d4e771
https://jersey.dev.java.net/nonav/apidocs/latest/contribs/jersey-apache-client/com/sun/jersey/client/apache/package-summary.html

2) Use POST with the override header, X-HTTP-Method-Override, which
says you really mean DELETE. This requires the server understand such
a header (there is a server filter in Jersey for this [1]).

Paul.

The problem is that the default client produces synchronous WebResource to
grab the response back.
When using @DELETE there is no need to synchronize request for idempotent
requirement.
I just changes the call to the following format and it works like charm

ClientConfig clientConfig = new DefaultClientConfig();
clientConfig.getFeatures().put(JSONConfiguration.FEATURE_POJO_MAPPING,
Boolean.TRUE);
Client c = Client.create(clientConfig);
AsyncWebResource ar =
c.*asyncResource*("http://127.0.0.1:8888/r/at/delete");
r.delete(Status.class, reqStatus);

Code Well,
Moshe Beeri.
