Javascript调用Java Applet签名

Question

我的功能小程序

public String sign(String data) {
    String rs = "";
    if (data != null && !data.isEmpty()) {
        loadKeyStore();
        if (lsCertificateId.size() > 0) {
            selectCertId();
        //doSign
            if (password != null && !password.isEmpty()
            && selectedId != null && !selectedId.isEmpty()) {
                byte[] signedData = doSign(data.getBytes());
                rs = Base64.encode(signedData);
            }
        }
    }
    return rs;
}

我从javascript调用函数applet，我已允许Java（TM）在浏览器上运行

                        </script>-->
        </form>

当我打开HTML文件时，出现错误：

var dataSigned = document.appSign.sign($("#txtData").val()); is not a function

有谁知道如何修理它？

使用证书对小程序和所有.jar依赖项进行签名。
用下面提到的所有标签填充清单（由于我使用maven，所以它在xml中，您可以按照自己喜欢的方式编写）

<codebase>http://location.of.your.jar/</codebase>
<permissions>all-permissions</permissions>
<Application-Library-Allowable-Codebase>http://location.of.your.jar/</Application-Library-Allowable-Codebase>
<Manifest-Version>1.0</Manifest-Version>
<Implementation-Title>App Name</Implementation-Title>
<Implementation-Version>0.1.0</Implementation-Version>
<Application-Name></Application-Name>
<Created-By>1.8.0_45</Created-By>
<Main-Class>package.YourClass</Main-Class>
<mode>development (or production)</mode>
<url>url of the application</url>

用doPrivileged包围Java方法
确保您的浏览器启用了Java插件
将您的Web应用程序的http路径放入Java例外列表中
如果您的网址包含_ （下划线/下划线），则可能无法识别。
尝试将.jar移到html的同一文件夹中，而不要使用/ applet文件夹。
看一下这篇文章，我有一个类似的问题。

请记住，此错误说“不是函数”是因为您的.jar未加载-或您在js语法中出错了，我不这么认为。
