Jersey 2 injection source for multipart formdata

Question

I had a method:

@POST @Consumes("multipart/form-data") @Produces( {"text/xml"}) public Response processForm(     @FormDataParam("myparam") InputStream is,     @FormDataParam("myparam") FormDataContentDisposition detail) 

which worked fine with Jersey 1.x.

I'm upgrading to 2.0 m11.

Now I get the following error:

12/01/2013 11:15:04 AM org.glassfish.jersey.server.ApplicationHandler initialize INFO: Initiating Jersey application, version Jersey: 2.0-m11 2012-12-21 12:34:15... 12/01/2013 11:15:04 AM org.glassfish.jersey.internal.Errors processErrors SEVERE: The following errors and warnings have been detected: WARNING: No injection source found for a parameter of type public javax.ws.rs.core.Response com.plutext.FileUpload.processForm(java.io.InputStream,org.glassfish .jersey.media.multipart.FormDataContentDisposition) at index 0. 

I found http://java.net/jira/browse/JERSEY-1413 and commit http://java.net/projects/jersey/lists/commits/archive/2012-09/message/126 which seems relevant, but its not obvious to me what to do to fix the problem.

UPDATED

I made a servlet, which runs in Tomcat before org.glassfish.jersey.server.ApplicationHandler initialize:

public class Jersey2Init extends HttpServlet {      private static final Logger jul = Logger.getLogger(Jersey2Init.class         .getName());      static {             System.out.println("\n\nrunning Jersey2Init\n\n");          final ResourceConfig resourceConfig1 = new ResourceConfig(XFormService.class);         resourceConfig1.registerInstances(new LoggingFilter(jul, true));         resourceConfig1.register(MultiPartFeature.class);                 final ResourceConfig resourceConfig2 = new ResourceConfig(AssembleService.class);         resourceConfig2.registerInstances(new LoggingFilter(jul, true));         resourceConfig2.register(MultiPartFeature.class);            } } 

It is definitely running first:

INFO: Deploying web application archive C:\Java\apache-tomcat-7.0.29\webapps\Foo-Services.war   running Jersey2Init   18/01/2013 9:09:51 PM org.glassfish.jersey.server.ApplicationHandler initialize INFO: Initiating Jersey application, version Jersey: 2.0-m11 2012-12-21 12:34:15... 18/01/2013 9:09:52 PM org.glassfish.jersey.internal.Errors processErrors SEVERE: The following errors and warnings have been detected: 

But I still get the same error.

Answer 1

You need to enable MultiPart feature on your application. Enabling this feature injects necessary message body readers, writers to your Jersey 2 application. Here is how you register them:

On the server-side (http-server):

final ResourceConfig resourceConfig = new ResourceConfig(MultiPartResource.class); resourceConfig.register(MultiPartFeature.class); 

On the server-side (servlet deployment):

import org.glassfish.jersey.filter.LoggingFilter; import org.glassfish.jersey.media.multipart.MultiPartFeature;  import javax.ws.rs.core.Application; import java.util.HashSet; import java.util.Set;  public class MyApplication extends Application {     @Override     public Set<Class<?>> getClasses() {         final Set<Class<?>> classes = new HashSet<Class<?>>();         // register resources and features         classes.add(MultiPartFeature.class);         classes.add(MultiPartResource.class);         classes.add(LoggingFilter.class);         return classes;     } } 

web.xml

<?xml version="1.0" encoding="UTF-8"?>     <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 Servlet</servlet-name>         <servlet-class>org.glassfish.jersey.servlet.ServletContainer</servlet-class>         <init-param>             <param-name>javax.ws.rs.Application</param-name>             <param-value>com.aruld.jersey.multipart.MyApplication</param-value>         </init-param>         <load-on-startup>1</load-on-startup>     </servlet>     <servlet-mapping>         <servlet-name>Jersey Servlet</servlet-name>         <url-pattern>/*</url-pattern>     </servlet-mapping> </web-app> 

On the client-side:

final ClientConfig clientConfig = new ClientConfig(); clientConfig.register(MultiPartFeature.class); Client client = ClientFactory.newClient(clientConfig); 

I put together an end-to-end Jersey 2 MultiPart sample in Github here.
