Send file via POST request

[jamalissimo]

Hello guys,

I am currently working on quite exciting assignment. Here is what I want to
do:

@GET REST response -> CXF to get parameters from exchange -> 3rd Party API
to get session_id -> BEAN to send data via POST method and in
multipart/mixed( it is for uploading files )

My first problem is that I don't know how to set the REST, for now it looks
like this:

@GET
@Path("/{myServerHost}/upload")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.MULTIPART_FORM_DATA)

public Response uploadFile(@PathParam("myHost") String knowledgetreeHost,
                        @QueryParam("myPort") String knowledgetreePort, 
@QueryParam("user")
String user,
                        @QueryParam("password") String password, 
@QueryParam("file") String file)
{
                return null;
}

Then I have route and I am setting http method to post

.when(header(CxfConstants.OPERATION_NAME).isEqualTo("uploadFile"))
 
.recipientList("https://myserver.com/service/?method=login&username=myusername&password=123456";)
     .beanRef("myBean", "getSessionId")
      // For now I needed data in GET(session_id),it is no problem, but in
the following method
      // I need to send POST request 
       .setHeader(Exchange.HTTP_METHOD, constant("POST"))
        .beanRef("myBean","uploadMyFile")
.endChoice()

Method uploadMyFile should send POST request. For now it looks like this:

        public void uploadMyFile(Exchange exchange) throws IOException {
                //SESSION_ID is set in previous steps of route
                String sessionId = 
exchange.getProperty("SESSION_ID").toString();
               //FILENAME is taken from URL
               /**
                  String filename = (String) msgList.get(4);
                  exchange.setProperty("FILENAME", filename);
                */
                String filename = 
"@"+exchange.getProperty("FILENAME").toString();
                String pathToUploader = 
"https://myserver.com/service/upload.php";;

                // Instantiate an HttpClient
                HttpClient client = new HttpClient();

                // Instantiate a POST HTTP method
                PostMethod method = new PostMethod(pathToUploader);
                method.setRequestHeader("Content-type",
exchange.getIn().getHeader("CONTENT_TYPE") + ";charset="+
exchange.getIn().getHeader("CONTENT_ENCODING"));

                // Define name-value pairs to set into the QueryString

                NameValuePair nvp1 = new NameValuePair("session_id", sessionId);
                NameValuePair nvp2 = new NameValuePair("action", "A");
                NameValuePair nvp3 = new NameValuePair("myfile", filename);
                
                method.setQueryString(new NameValuePair[] { nvp1, nvp2, nvp3 });

                try {
                        int statusCode = client.executeMethod(method);

                        System.out.println("Status Code = " + statusCode);
                        System.out.println("QueryString>>> " + 
method.getQueryString());
                        System.out.println("Status Text>>>" +
HttpStatus.getStatusText(statusCode));

                        // Get data as a String
                        System.out.println(method.getResponseBodyAsString());
                        
                        exchange.getIn().setHeader("HTTP_METHOD", "POST");
                        
exchange.getIn().setBody(method.getResponseBodyAsString());

                        // release connection
                        method.releaseConnection();
                } catch (IOException e) {
                        e.printStackTrace();
                }

        }

Basically I need to know how to set REST and how to set POST method for CXF

Thanks
