アプレットの特定のボタンがクリックされたときにjarをロードしたいと思います。

アプレットのロード時に jar に対するセキュリティ警告がユーザーに表示されないようにしたいのですが、ボタンをクリックすると警告が表示されます。

WebStart を使用しています。

コードとエラーは次のとおりです。

    Policy.setPolicy(new Policy() {
        public PermissionCollection getPermissions(CodeSource codesource) {
            Permissions perms = new Permissions();
            perms.add(new AllPermission());
            return (perms);
        }

        public void refresh() {
        }
    });

    System.setSecurityManager(null);

    ClassLoader wcl = MainApplet.class.getClassLoader();

    URL[] urls = new URL[1];
    String protocol="http";
    String host="localhost";
    int port = 8080;
    String file = "MB/download/ubikey-1.0.2.5.jar";
    //      String url = URLEncoder("http://localhost:11090/MultiToolkitDemo/download/ubikey-1.0.2.5.jar");
    urls[0] = new URL(protocol, host, port, file);


    try {
        ds = (DownloadService) ServiceManager
                .lookup("javax.jnlp.DownloadService");

        // determine if a particular resource is cached
        URL url = new URL(
                "http://localhost:8080/MB/download/ubikey-1.0.2.5.jar");
        boolean cached = ds.isResourceCached(url, "1.0");
        // remove the resource from the cache
        if (cached) {
            ds.removeResource(url, "1.0");
        }
        // reload the resource into the cache
        DownloadServiceListener dsl = ds.getDefaultProgressWindow();
        ds.loadResource(url, "1.0", dsl);
    } catch (Exception e) {
        e.printStackTrace();
    }
    URLClassLoader cl = new URLClassLoader(urls, wcl);
    try {
        cl.loadClass("kr.co.JUBIKey.JUBIKeyManager");
    } catch (ClassNotFoundException e1) {
        // TODO Auto-generated catch block
        e1.printStackTrace();
    }

エラーは次のとおりです。

いいえ。それはオプションではありません。アプリの前にセキュリティ チェックが実行されます。画面にします。
