exception - Jersey: How to register MultiPartConfigProvider class -

i'm trying load multiple files jersey, demands me configuration can't find. dependency, had add because jersey couldn't resolver type "multipart/related":

<dependency>     <groupid>org.glassfish.jersey.media</groupid>     <artifactid>jersey-media-multipart</artifactid>     <version>2.7</version>  </dependency> 

this api use multipart:

    @put     @consumes("multipart/related")     @path("/{id}/user/{userid}")     public response loadfile(@pathparam("id") int id, @pathparam("userid") int userid, multipart files) throws exception{         int resultado = tool.loadfile(id, userid, files);         switch (resultado){         case 401:   return response.status(401).entity("no existe el experimento con id: "+id).build();         case 402:   return response.status(402).entity("el tipo de uno de los archivos no se encuentra en los tipos de entregables del experimento").build();         case 403:   return response.status(403).entity("el usuario: "+userid+" no participa en el experimento").build();         case 405:   return response.status(405).entity("debe ingresar un comentario").build();         case 406:   return response.status(406).entity("hay entregables sin subir").build();         case 200:   return response.status(200).build();         }         return null;     } 

this web.xml, think missing here:

    <?xml version="1.0" encoding="utf-8"?> <!-- web.xml file not required when using servlet 3.0 container,      see implementation details http://jersey.java.net/nonav/documentation/latest/jax-rs.html --> <web-app version="2.5" xmlns="http://java.sun.com/xml/ns/javaee" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xsi:schemalocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd">     <servlet>         <servlet-name>jersey web application</servlet-name>         <servlet-class>org.glassfish.jersey.servlet.servletcontainer</servlet-class>         <init-param>             <param-name>jersey.config.server.provider.packages</param-name>             <param-value>org.mockapi</param-value>         </init-param>         <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>         <servlet-name>jersey web application</servlet-name>         <url-pattern>/rest/*</url-pattern>     </servlet-mapping> </web-app> 

and exception:

a multiexception has 3 exceptions.  are: 1. java.lang.illegalargumentexception: multipartconfig instance expected not present.  have registered multipartconfigprovider class? 2. java.lang.illegalstateexception: unable perform operation: create on com.sun.jersey.multipart.impl.multipartreaderclientside 3. java.lang.illegalstateexception: unable perform operation: create on org.glassfish.jersey.message.internal.messagebodyfactory 

if using new version of dropwizard, dependency should be, <dependency> <groupid>org.glassfish.jersey.media</groupid> <artifactid>jersey-media-multipart</artifactid> <version>2.15</version> </dependency> because new version of dropwizard uses org.glassfish.jersey.core:jersey-server:jar.
, have register multipartfeature in our application's run method environment.jersey().register(multipartfeature.class);
