No message body reader has been found for class org.glassfish.jersey.media.multipart.FormDataContentDisposition

Question

Kind of new to rest web services. Particularly with file uploading. I get this error when trying to upload a file using a java restful service using Jersey 3.0.

01-Oct-2020 13:58:20.906 SEVERE [http-nio-8080-exec-54] org.apache.cxf.jaxrs.utils.JAXRSUtils.logMessageHandlerProblem No message body reader has been found for class org.glassfish.jersey.media.multipart.FormDataContentDisposition, ContentType: multipart/form-data;boundary=---------------------------3611873841451717332877493500 01-Oct-2020 13:58:20.906 WARNING [http-nio-8080-exec-54] org.apache.cxf.jaxrs.impl.WebApplicationExceptionMapper.toResponse javax.ws.rs.WebApplicationException: HTTP 415 Unsupported Media Type

I know this question has been asked numerous times but none of the solutions seem to work. So I will be posting my code, etc. Any help appreciated. Let me know if you need more info. Thanks in advance!

I am deploying this service on Apache Tomcat (TomEE)/9.0.37 (8.0.4) I am using Eclipse Neon.3 Release (4.6.3). I am not using maven on this project currently.

here is my service class

@Path("/")
public class FileUpload extends Application{

    /** The path to the folder where we want to store the uploaded files */
    private static final String UPLOAD_FOLDER = "c:/projects/";
    public FileUpload() {
    }
    @Context
    private UriInfo context;

    /**
     * Returns text response to caller containing uploaded file location
     * 
     * @return error response in case of missing parameters an internal
     *         exception or success response if file has been stored
     *         successfully
     */
    @Path("/upload")
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    @Produces(MediaType.TEXT_PLAIN)
    public Response uploadFile
    (
            @FormDataParam("file") InputStream uploadedInputStream,
            @FormDataParam("file") FormDataContentDisposition fileDetail)  throws Exception{
        // check if all form parameters are provided
        
        System.out.println("Inside uploadfile");
        
        
        if (uploadedInputStream == null || fileDetail == null)
            return Response.status(400).entity("Invalid form data").build();
        // create our destination folder, if it not exists
        try {
            createFolderIfNotExists(UPLOAD_FOLDER);
        } catch (SecurityException se) {
            return Response.status(500)
                    .entity("Can not create destination folder on server")
                    .build();
        }
        String uploadedFileLocation = UPLOAD_FOLDER + fileDetail.getFileName();
        try {
            saveToFile(uploadedInputStream, uploadedFileLocation);
        } catch (IOException e) {
            return Response.status(500).entity("Can not save file").build();
        }
        return Response.status(200)
                .entity("File saved to " + uploadedFileLocation).build();
    }
    

    /**
     * Utility method to save InputStream data to target location/file
     * 
     * @param inStream

     */
    private void saveToFile(InputStream inStream, String target)
            throws IOException {
        OutputStream out = null;
        int read = 0;
        byte[] bytes = new byte[1024];
        out = new FileOutputStream(new File(target));
        while ((read = inStream.read(bytes)) != -1) {
            out.write(bytes, 0, read);
        }
        out.flush();
        out.close();
    }
    /**

     * 
     * @param dirName
     *            - full path to the folder

     *             - in case you don't have permission to create the folder
     */
    private void createFolderIfNotExists(String dirName)
            throws SecurityException {
        File theDir = new File(dirName);
        if (!theDir.exists()) {
            theDir.mkdir();
        }
    }
}

Below is my Application class. Not even sure if I need this or not. Someone suggested I did.

package edu.pcom.docusign;

import javax.ws.rs.ApplicationPath;
import org.glassfish.jersey.media.multipart.MultiPartFeature;
import org.glassfish.jersey.server.ResourceConfig;

@ApplicationPath("")
public class DemoApplication extends ResourceConfig{
    
    DemoApplication(){
        register( MultiPartFeature.class );
        registerClasses( FileUpload.class ); 
    }
}

There is no web.xml because I am using annotations.

These are the libs I am using.
