java - How to fire HTTP post with content type XML along with query parameters? -

i trying fire post request. data sending xml format (i doing via jaxb), have send along request parameter. problem regarding content-type (i've added comments in code). 1 should use ?

see below code :

       private v callandgetresponse(k request, class<k> requestclasstype, class<v> responseclasstype) throws exception {     jaxbcontext jaxbcontext = jaxbcontext.newinstance(requestclasstype, responseclasstype);      marshaller marshaller = jaxbcontext.createmarshaller();     // set properties on marshaller     marshaller.setproperty(marshaller.jaxb_formatted_output, true);     marshaller.setproperty(marshaller.jaxb_encoding, charset);     marshaller.setproperty("com.sun.xml.internal.bind.xmlheaders", string.format(xml_header_format, dtd));     marshaller.marshal(request, system.out);      url wsurl = new url(primaryendpointurl);     httpurlconnection connection = openandprepareconnection(wsurl);     trytomarshallwsrequesttooutputstream(request, marshaller, connection);      printdebug(connection);      unmarshaller unmarshaller = jaxbcontext.createunmarshaller();     object response = unmarshaller.unmarshal(connection.getinputstream());      // cleanup     connection.disconnect();     return responseclasstype.cast(response); }  private httpurlconnection openandprepareconnection(url wsurl) throws ioexception {     httpurlconnection connection = (httpurlconnection) wsurl.openconnection();     connection.setdooutput(true);     connection.setrequestproperty("accept", "application/xml");     connection.setrequestproperty("accept-charset", charset);     // both types ? doesn't work     connection.setrequestproperty("content-type", "application/xml;application/x-www-form-urlencoded");     // app/xml ? seems query param not added request     connection.setrequestproperty("content-type", "application/xml");     // app/query param ? seems xml not added request     connection.setrequestproperty("content-type", "application/x-www-form-urlencoded");      return connection; }  private void trytomarshallwsrequesttooutputstream(k request, marshaller jaxbforrequestmarshaller,         httpurlconnection connection) throws jaxbexception, ioexception {     outputstream outputstream = null;     try {         outputstream = connection.getoutputstream();         jaxbforrequestmarshaller.marshal(request, outputstream);         addqueryparameters(outputstream);     }     {         trytoclose(outputstream);     } }  private void addqueryparameters(outputstream outputstream) throws ioexception {     string value = "none";     string query = string.format("xmlmsg=%s", urlencoder.encode(value, charset));     outputstream.write(query.getbytes(charset)); }  protected void trytoclose(outputstream outputstream) throws ioexception {     if (outputstream != null) {         outputstream.close();     } } 

thanks lot!

ok, there's 2 different issues you're dealing with:

1) content-type of body. in case, if body xml body, should be:

content-type: application/xml; charset="utf-8" 

2) fact query parameters being stripped off (or ignored). more complicated problem. when form submitted via http post, sent query string params, , looks might happening. can wire trace of what's being sent? may you'll need parse parameters off instead of trying parse them form body.

if need send 2 different types of data, may consider sending multipart form, or sending 1 body type, , adding data header.
