-

im trying create , download zip file in java using restful service. not working me. please find code below:

        @get     @path("/exportzip")     @produces("application/zip")     public response download(@queryparam("dim") final string dimid,             @queryparam("client") final string clientid,             @queryparam("type") final string type,             @context uriinfo ui) {         system.out.println("start");          responsebuilder response = null ;          string filetype = "";          if(type.equalsignorecase("u")){             filetype = "unmapped";          }else if(type.equalsignorecase("m")){             filetype = "mapped";          }         try {              byte[] workbook = null;             workbook = engineservice.export(dim, client, type);              inputstream = new bytearrayinputstream(workbook);              fileoutputstream out = new fileoutputstream(filetype + "tmp.zip");              int buffersize = 1024;             byte[] buf = new byte[buffersize];             int n = is.read(buf);             while (n >= 0) {                 out.write(buf, 0, n);               n = is.read(buf);             }              response = response.ok((object) out);              response.header("content-disposition",                     "attachment; filename=\"" + filetype + " - " + new date().tostring() + ".zip\"");              out.flush();             out.close();           catch (filenotfoundexception e) {             e.printstacktrace();         } catch (ioexception e) {             e.printstacktrace();         }         system.out.println("end");         return response.build();     }

this giving me following error: javax.ws.rs.webapplicationexception: com.sun.jersey.api.messageexception: message body writer java class java.io.fileoutputstream, , java type class java.io.fileoutputstream, , mime media type application/zip not found

you haven't added mime type of response . browser confused while processing response. needs response content type. set response content type response, add following code ,

          response.setcontenttype("application/zip");

after

          response = response.ok((object) out);

thanks.

i used pyinstaller create standalone exe file pyqt project. did not use single file option because exe created single file option takes long open. therefore, pyinstaller created dist folder contains bunch of files including program.exe file. create setup.exe file place contents of dist folder in program directory , create shortcut in start menu , on desktop. want super simple user. maybe setup.exe files when download program cnet. found inno-setup, looks promising. however, not know if there special considerations because program standalone program create python/pyqt program. thanks! have experience task? there program using task not know about? inno-setup or nsis easiest use. tell them files include , put them , create nice installer you. wrote short tutorial on experiences using innosetup might find helpful: http://www.blog.pythonlibrary.org/2008/08/27/packaging-wxpymail-for-distribution/ note tutorial based around wxpython app wrote, concepts same.
