如何在jsf页

Question

我用java applet扫描图片之后需要在我的露天服务器上传，所以我认为我可以用http请求发送数据 但我不知道如何告诉我的jsf页面来处理这个请求  在这里我的网页：

<h:form id="docForm">
                        <h:outputText rendered="#{documentAjoutBean.showGedErrorMessage}"
                                value="#{msg.errorCodeGedConnexion}" styleClass="error"
                                style="margin-left: 3px; padding-bottom: 3px;" />
                            <rich:messages ajaxRendered="true" errorClass="msgError"
                                styleClass="error" />

这是我的web.xml：

这是我的servlet：

   public class ScannerServlet implements HttpRequestHandler {

    System.out
            .println("################################init Scanner Servlet##################################");

        HttpServletResponse response) {
    System.out.println("ScannerServ-*-!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!");
    ByteArrayOutputStream byteArrayOutputStream = null;
    int len = 0;
    int size = 1024;

    byte[] data;
    DataInputStream dataInputStream = null;

    try {
        dataInputStream = new DataInputStream(request.getInputStream());
        byteArrayOutputStream = new ByteArrayOutputStream();
        data = new byte[1024];
        while ((len = dataInputStream.read(data, 0, 1024)) != -1) {
            System.out.println("  setData!!!");
            byteArrayOutputStream.write(data, 0, len);
            data = byteArrayOutputStream.toByteArray();

        }
            scannerSevrice.setData(ScannerUtils
                    .imageByteArrayToPdfByteArray(data));

        dataInputStream.close();

        System.out.println("received " + data.length + " bytes from "
