i have seen multiple answers on stackoverflow , yet unable identify wrong pom.xml. have upload files on server, using modified code formdatamultipart of this link

i have code as:

import java.io.file; import java.io.fileoutputstream; import java.io.ioexception; import java.io.inputstream; import java.io.outputstream;  import javax.ws.rs.consumes; import javax.ws.rs.post; import javax.ws.rs.path; import javax.ws.rs.core.mediatype; import javax.ws.rs.core.response;  import org.glassfish.jersey.media.multipart.contentdisposition; import org.glassfish.jersey.media.multipart.formdatabodypart; import org.glassfish.jersey.media.multipart.formdatamultipart;  @path("/files") public class jerseyfileupload {  private static final string server_upload_location_folder = "e:/upload_files/";  @post @path("/upload") @consumes(mediatype.multipart_form_data) public response uploadfile(formdatamultipart form) {       formdatabodypart filepart = form.getfield("file");       contentdisposition headeroffilepart =  filepart.getcontentdisposition();       inputstream fileinputstream = filepart.getvalueas(inputstream.class);       string filepath = server_upload_location_folder + headeroffilepart.getfilename();      // save file server     savefile(fileinputstream, filepath);      string output = "file saved server location using formdatamultipart : " + filepath;      return response.status(200).entity(output).build();  }  // save uploaded file defined location on server private void savefile(inputstream uploadedinputstream, string serverlocation) {      try {         outputstream outpustream = new fileoutputstream(new file(                 serverlocation));         int read = 0;         byte[] bytes = new byte[1024];          outpustream = new fileoutputstream(new file(serverlocation));         while ((read = uploadedinputstream.read(bytes)) != -1) {             outpustream.write(bytes, 0, read);         }          outpustream.flush();         outpustream.close();          uploadedinputstream.close();     } catch (ioexception e) {          e.printstacktrace();     }  }   }

i using jersey version 2.16, still getting "unsupported media type", though using jersey-media-multipart version 2.25. there issue due version? or wrong pom.xml??

thanks, grateful help.

you still need register multipartfeature comes jersey-media-multipart. feature register providers needed handle multipart requests. error you're seeing because there no providers registered can handle formdatamultipart. see this post couple different ways of registering it
