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

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;
    }
}

            <param-name>javax.ws.rs.Application</param-name>

        </init-param>

    </servlet>

        <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.
