JSF managed upload bean?

Question

I have an upload routine which is working for servlets. Now I was trying to put this routine in a jsf managed bean like this:

 public void uploadFile() throws IOException, ServletException{

    FacesContext facesContext = FacesContext.getCurrentInstance();
    ExternalContext externalContext = facesContext.getExternalContext();
    HttpServletRequest request = (HttpServletRequest) externalContext.getRequest();
    HttpServletResponse response = (HttpServletResponse) externalContext.getResponse();


    Part filePart = request.getPart("item");
    String filename = getFilename(filePart);
    InputStream filecontent = filePart.getInputStream();

    //persist the data here

}

when trying to run it on the server, of course there is the error message: "PWC4016: Request.getPart is called without multipart configuration. Either add a @MultipartConfig to the servlet, or a multipart-config element to web.xml"

But I don't know where to put this annotation, neither do I have the name of the jsf generated servlet of my managed bean so I can't put it into the web.xml neither. Is it generally a bad idea to put this routine into a managed bean or should I stick to the servlet variant?

The @MultipartConfig basically needs to be put on the FacesServlet. You can't do it yourself, but this is already done for the upcoming JSF 2.2, complete with a new standard <h:inputFile> component with ajax support, see also JSF spec issue 802.

Until then, your best bet is grabbing a 3rd party component library or homebrewing a custom component.

Tomahawk <t:inputFileUpload> - see also JSF 2.0 File upload
PrimeFaces <p:fileUpload> - see also How to use PrimeFaces p:fileUpload?
Custom <x:inputFile> - see also Uploading files with JSF 2.0 and Servlet 3.0

currently I'm using JUpload Applet for upload files, so uploading is not the problem. It's rather that processing the upload with a managed beans seems not possible at the moment – nico1510 Oct 12 '12 at 10:25
If the source is not a JSF view, why do you need a JSF model then? Indeed just use a simple servlet then. Even with JSF 2.2 it would not be (nicely) possible. – BalusC Oct 12 '12 at 10:27
Since I have a file downloadlink in my jsf and a managedbean which serves the file to download (according to your post at [link](http://stackoverflow.com/a/3428207/1644061) ) I thought it would be a good idea to put the upload routine also in this bean. But I think thats the wrong decision right? – nico1510 Oct 12 '12 at 11:31
Depends on whether JSF is absolutely mandatory to serve the file. For example, you need to download the file by a JSF POST request instead of a simple GET request because there are some input fields involved for which you'd like to perform JSF validation and so on. – BalusC Oct 12 '12 at 11:37
