java - How to send requests and receive responses to/from an Apache CXF-based service? -

i have several servlets,

1. take json-encoded requests inputs,
2. process them and
3. return responses client json-encoded objects.

up used android client (sample android code see below).

now want write plain old java program, send requests , receive responses (do same android code). purpose wrote java test (code see below, section java code) , ran it.

at client side error:

21:43:38.930 [main] error r.a.c.t.testacceptanceprocedure1 -  java.io.ioexception: server returned http response code: 405 url: http://myserver/myapp/rest/getuseridservice     @ sun.net.www.protocol.http.httpurlconnection.getinputstream(httpurlconnection.java:1441) ~[na:1.6.0_23]     @ testclient.testacceptanceprocedure1.test(testacceptanceprocedure1.java:47) ~[test-classes/:na] 

in server log, see message:

warning: no operation matching request path "/myapp/rest/getuseridservice" found, relative path: /, http method: get, contenttype: */*, accept: text/html,image/gif,image/jpeg,*/*,*/*;q=.2,. please enable fine/trace log level more details 

question: how should change java test fix error?

note server , running (when execute android code, works).

android code:

sending request , receiving response:

final getsimulationstatusrequest request = new getsimulationstatusrequest(); final string json = utils.converttojson(request, getclass()); final string serverurl = utils.getserverurl(this, "getsimulationstatusservice");  final igetsimulationstatusasynctask getsimulationstatustask =          asynctaskfactory.creategetsimulationstatusasynctask(getwebservicehelper());  utils.setrequestandserverurl(json, serverurl, getsimulationstatustask);  final getsimulationstatusresponse simulationstatusreponse =          getsimulationstatustask.get(); 

utils.converttojson:

public static string converttojson(final object arequest, class<? extends activity> aclass) {     final objectmapper mapper = new objectmapper();     string json = null;      try {         json = mapper.writevalueasstring(arequest);     } catch (final jsonprocessingexception exception) {         log.e(aclass.getsimplename(), exception.getlocalizedmessage(),                 exception);     }     return json; } 

utils.setrequestandserverurl:

public static void setrequestandserverurl(final string ajson,         final string aserverurl, final iasynctask atask) {     atask.addnamevaluepair("request", ajson);     atask.sendrequest(new string[] { aserverurl }); } 

getsimulationstatusasynctask:

public class getsimulationstatusasynctask      extends asynctask<string, string, getsimulationstatusresponse>      implements igetsimulationstatusasynctask {     private static final string tag = getsimulationstatusasynctask.class.getsimplename();     private iwebservicetaskhelper helper;     private iccpresponseparser<getsimulationstatusresponse> responseparser =              new ccpresponseparser<getsimulationstatusresponse>();       public getsimulationstatusasynctask(final iwebservicetaskhelper ahelper) {         helper = ahelper;     }      @override     public void addnamevaluepair(final string aname, final string avalue) {         helper.addnamevaluepair(aname, avalue);     }      @override     protected getsimulationstatusresponse doinbackground(string... aargs) {         return (getsimulationstatusresponse)utils.processresponse(this.helper, tag, responseparser,                  getsimulationstatusresponse.class, aargs);     }      @override     public void sendrequest(final string[] aargs) {         execute(aargs);     } } 

java code:

@test public void test() throws jsonprocessingexception, malformedurlexception {     final getuseridrequest request = new getuseridrequest();      request.setdeviceid("pc1");      final string requestasstring = converttojson(request);     final string serverurl = getserverurl("getuseridservice");      final url url = new url(serverurl);     httpurlconnection connection = null;     inputstream inputstream = null;     try {          connection = (httpurlconnection) url.openconnection();         connection.addrequestproperty("request", requestasstring);         connection.connect();          inputstream = connection.getinputstream();         final string responseasstring = ioutils.tostring(inputstream);          logger.debug("responseasstring: " + responseasstring);      } catch (final ioexception exception) {         logger.error("", exception);     }         {         ioutils.closequietly(inputstream);     } }  private string converttojson(final getuseridrequest arequest) throws jsonprocessingexception {     final objectmapper mapper = new objectmapper();     return mapper.writevalueasstring(arequest); }  private string getserverurl(final string aservicename) {     return "http://myserver.com/myapp/rest/" + aservicename; } 

update 1 (09.10.2013 12:23 msk):

@path("/getsimulationstatusservice") public class getsimulationstatusservice extends baseccpservice  {   private getsimulationstatusrequestparser requestparser =        new getsimulationstatusrequestparser();    @post   @produces("text/plain")   public string getsimulationstatus(@formparam("request") final string arequestjson)        throws jsonprocessingexception   {     final getsimulationstatusrequest request = requestparser.convert(arequestjson);      final getsimulationstatusresponse response = new getsimulationstatusresponse();      response.setrequestid(request.getid());     response.setcycle(getpersistence().getcurrentcycle(request.getuserid()));     response.setlabourforce(getpersistence().getlabourforcesimulationparameter(         request.getuserid()));      return getobjectmapper().writevalueasstring(response);   } } 

update 2 (09.10.2013 20:48 msk): when change code shown below, 500 http response. @ server side, arequest argument of method getuseridservice.getuserid null.

        connection = (httpurlconnection) url.openconnection();         connection.addrequestproperty("request", requestasstring);         connection.setrequestmethod("post"); // added line         connection.connect(); 

update 3 (09.10.2013 23:15): 1 works:

@test public void test() throws jsonprocessingexception, malformedurlexception  {     final getuseridrequest request = new getuseridrequest();      request.setdeviceid("pc1");      final string requestasstring = converttojson(request);     final string serverurl = getserverurl("getuseridservice");      final url url = new url(serverurl);     httpurlconnection connection = null;     inputstream inputstream = null;     outputstream outputstream = null;     try {          connection = (httpurlconnection) url.openconnection();         connection.setrequestmethod("post");         connection.setdooutput(true);         connection.connect();          outputstream = connection.getoutputstream();          ioutils.write("request=" + requestasstring, outputstream);          inputstream = connection.getinputstream();         final string responseasstring = ioutils.tostring(inputstream);          logger.debug("responseasstring: " + responseasstring);      } catch (final ioexception exception) {         logger.error("", exception);     }         {         ioutils.closequietly(inputstream);         ioutils.closequietly(outputstream);     } } 

the 405 http error code means given method (get) not supported endpoint. instead of request want send post. don't know kind of request sent android client.

do have endpoint specification/documentation?

here you'll find information how invoke post using plain java api. if can use external libraries in test can achieved lot easier using resteasy.
