A message body reader for FormDataMultiPart was not found

Question

I'm having some trouble with using FormDataMultiPart.

For some reason it looks as if the config for MultiPartFeature isn't getting called, even though i have put it in my web.xml, here is my code below.

web.xml

    <servlet>
    <servlet-name>REST</servlet-name>
    <servlet-class>com.sun.jersey.spi.container.servlet.ServletContainer</servlet-class>
    <init-param>
        <param-name>com.sun.jersey.config.property.packages</param-name>
        <param-value>com.rest</param-value>
    </init-param>
    <init-param>
        <param-name>jersey.config.server.provider.classnames</param-name>
        <param-value>org.glassfish.jersey.media.multipart.MultiPartFeature</param-value>
    </init-param>
    <load-on-startup>1</load-on-startup>
</servlet>

My rest method

@POST
@Path("/users/{userId}/images")
@Produces(MediaType.APPLICATION_JSON)
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadImage(@HeaderParam("securityToken") String securityToken, @PathParam("userId") Integer userId,
                            FormDataMultiPart form) {}

and the log message

With Jersey 2.x and a Servlet 3.x container, you don't need a web.xml deployment descriptor. For more details, check the Jersey documentation about deployment.

You could use the @FormDataParam annotation to bind the named body part(s) of a multipart/form-data request entity body to a resource method parameter, as exemplified below:

@POST
@Path("/upload")
@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response upload(@FormDataParam("file") InputStream inputStream,
                       @FormDataParam("file") FormDataContentDisposition fileMetaData) {
    ...
}

To use multipart features you need to add the jersey-media-multipart module to your pom.xml file:

<dependency>
    <groupId>org.glassfish.jersey.media</groupId>
    <artifactId>jersey-media-multipart</artifactId>
    <version>2.23.1</version>
</dependency>

If you're not using Maven make sure to have all needed dependencies (see jersey-media-multipart) on the classpath. And don't forget to register the MultiPartFeature in your Application/ResourceConfig sub-class.

For more details, check the Jersey documentation about multipart requests.
