Hi Guys.

I am trying to use Jersey to upload a file, but I get an error when I try to use the @FormDataParam annotation. See code and error below:

TestResource.java

@Path("/user")
public class TestResource {
	
	@POST
	@Path("/upload")
	@Consumes(MediaType.MULTIPART_FORM_DATA)
	public Response uploadFile(
		@FormDataParam("file") InputStream uploadedInputStream,
		@FormDataParam("file") FormDataContentDisposition fileDetail) {
 
		String uploadedFileLocation = "c://uploaded/" + fileDetail.getFileName();
 
		// save it
		writeToFile(uploadedInputStream, uploadedFileLocation);
 
		String output = "File uploaded to : " + uploadedFileLocation;
 
		return Response.status(200).entity(output).build();
 
	}
 
	// save uploaded file to new location
	private void writeToFile(InputStream uploadedInputStream,
		String uploadedFileLocation) {
 
		try {
			OutputStream out = new FileOutputStream(new File(
					uploadedFileLocation));
			int read = 0;
			byte[] bytes = new byte[1024];
 
			out = new FileOutputStream(new File(uploadedFileLocation));
			while ((read = uploadedInputStream.read(bytes)) != -1) {
				out.write(bytes, 0, read);
			}
			out.flush();
			out.close();
		} catch (IOException e) {
			e.printStackTrace();
		}
	}
}
