FileUpload with JAX-RS

Question

I try to do file upload from a JavaScript client to a JAX-RS Java server.

I use the following REST upload function on my server:

@POST
@Produces(\'ap         


        

Answer 1

There is no Jax-RS way to do this. Each server have their own extensions, all using Multi-part form submissions. For example, in CXF, the following will allow you to upload via a multipart form. (Attachment is a CXF specific extension)

@Consumes(MediaType.MULTIPART_FORM_DATA)
public Response uploadFile(@Multipart(value = "vendor") String vendor,
        @Multipart(value = "uploadedFile") Attachment attr) {

whereas the following is the same for Jersey (FormDataParam is a Jersey extension):

 @Consumes(MediaType.MULTIPART_FORM_DATA_TYPE)
 public String postForm(
         @DefaultValue("true") @FormDataParam("enabled") boolean enabled,
         @FormDataParam("data") FileData bean,
         @FormDataParam("file") InputStream file,
         @FormDataParam("file") FormDataContentDisposition fileDisposition) {

(I've ignored the @Path, @POST and @Produces, and other non-relevant annotations.)
