java - 对象不支持此方法或属性错误

Question

嗨，我创建了一个 jni jar，并使用 java 脚本中的小程序调用该 jar。我使用以下小程序标签创建一个对象以通过java脚本调用jar函数。当我调用该函数时，出现以下错误对象不支持此方法或属性。

这是我的代码。

document.write('<applet code="BiomAPI.Legend.class" width="0" height="0" archive="BiomAPI.jar" id="Obj"></applet>');

function GetTemplateAccurate (sUserID,iFingerID)
{
    document.getElementsByName("Enroll")[0].value = "";
    document.getElementsByName("Image")[0].value = "";
    var lsFeature = null;
    var lsImage = null;

    Obj.EnableLog(0);
    Obj.LocalFilePath("C:\\IMAGE\\");
    Obj.EnableEncryption(0);
    Obj.SaveImage(1);
    Obj.SessionID("abcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcdeabcde");
    Obj.GetFeatureAccrual(sUserID,iFingerID);
    lsFeature = Obj.Feature();  
    lsImage = Obj.StringImage();

    if (lsFeature != null && lsImage != null )
    {
        document.getElementsByName("Enroll")[0].value = lsFeature;
        document.getElementsByName("Image")[0].value = lsImage;
        alert("Scanner Working Properly");
    }
    else
    {
        alert("Fingerprint not captured");
    }
}

function GetTemplate(sUserID,iFingerID)
{
    document.getElementsByName("Verify")[0].value = "";
    var lsFeature = null;

    Obj.EnableLog(0);
    Obj.LocalFilePath("C:\\IMAGE\\");
    Obj.EnableEncryption(0);
    Obj.SessionID("abcde");
    Obj.SaveImage(1);
    Obj.GetFeature(sUserID,iFingerID);
    lsFeature = Obj.Feature();  
    lsImage = Obj.StringImage();

    if (lsFeature != null)
    {
        document.getElementsByName("Verify")[0].value = lsFeature;
        alert("Scanner Working Properly");
    }
    else
    {
        alert("Fingerprint not captured");
    }

}

异常本身正在描述:

Object doesn't support this method or property error

您尝试通过某个对象访问的属性或方法不受该对象支持。请调试或在错误控制台上查看抛出异常的对象，并确定它是否支持您尝试访问的属性。
