Corda attachment upload

I'm trying to add upload attachment in my Corda application but it's not working as I'm getting below error at start up itself.

[[FATAL] No injection source found for a parameter of type public javax.ws.rs.core.Response com.test.agreementnegotiation.api.AgreementNegotiationApi.uploadFile(java.lang.String,java.io.InputStream,org.glassfish.jersey.media.multipart.FormDataContentDisposition) at index 0.; source='ResourceMethod{httpMethod=POST, consumedTypes=[multipart/form-data], producedTypes=[], suspended=false, suspendTimeout=0, suspendTimeoutUnit=MILLISECONDS, invocable=Invocable{handler=ClassBasedMethodHandler{handlerClass=class com.test.agreementnegotiation.api.AgreementNegotiationApi, handlerConstructors=[org.glassfish.jersey.server.model.HandlerConstructor@14ab26a]}, definitionMethod=public javax.ws.rs.core.Response com.test.agreementnegotiation.api.AgreementNegotiationApi.uploadFile(java.lang.String,java.io.InputStream,org.glassfish.jersey.media.multipart.FormDataContentDisposition), parameters=[Parameter [type=class java.lang.String, source=tags, defaultValue=], Parameter [type=class java.io.InputStream, source=file, defaultValue=null], Parameter [type=class org.glassfish.jersey.media.multipart.FormDataContentDisposition, source=file, defaultValue=null]], responseType=class javax.ws.rs.core.Response}, nameBindings=[]}']

Below is the code -

@Path("upload")
    @POST
    @Consumes(MediaType.MULTIPART_FORM_DATA)
    public Response uploadFile(@DefaultValue("") @FormDataParam("tags") String tags,
                               @FormDataParam("file") InputStream file,
                               @FormDataParam("file") FormDataContentDisposition fileDisposition) {

        String fileName = fileDisposition.getFileName();
        saveFile(file, fileName);
        String fileDetails = "File saved at " + UPLOAD_FOLDER + " " + fileName + " with tags "+ tags;
        System.out.println(fileDetails);
        return Response.ok(fileDetails).build(); 
    }

    private void saveFile(InputStream file, String name) {
        try {
            /* Change directory path */
            java.nio.file.Path path = FileSystems.getDefault().getPath(UPLOAD_FOLDER + name);
            /* Save InputStream as file */
            Files.copy(file, path);
        } catch (IOException ie) {
            ie.printStackTrace();
        }
    }

I searched on error and found that we need to enable/resgiter MultiPartFeature.

https://www.google.co.uk/search?q=No+injection+source+found+for+a+parameter+site:stackoverflow.com&sa=X&ved=0ahUKEwjn5ePy5PbbAhWMOxQKHQHXAUkQrQIIUCgEMAI&biw=1280&bih=958

Whatever link I found they talk about changing web.xml or adding AppCong and I'm Not sure how it can be done in Corda sample project.

Corda team please help.

The endpoint of the deprecated webserver /upload/attachment does not work anymore in corda V4

The built-in node webserver has a default endpoint for uploading attachments, /upload/*. This endpoint is available out-of-the-box and does not need to be added in your API. You upload an attachment by making a POST request to this endpoint with the encoding type multipart/form-data.

For example:

<form action="/upload/attachment" method="post" enctype="multipart/form-data">
    <div class="form-group">
        <input type="file" name="jar" class="form-control">
    </div>
    <br>
    <button type="submit" class="btn btn-default">Upload blacklist</button>
</form>

You cannot provide your own additional endpoints for uploading attachments.

If you write your own node webserver (e.g. a Spring webserver), then there are no limitations.
