我正在尝试使用 java 执行 javascript 函数，但收到一条错误消息，指出它无法找到某些类。有人可以帮我解决这个问题吗？

我的 Java 课程

public class TestException {

    public static void main(String[] args) throws IOException,ScriptException {
        ScriptEngineManager engineMgr=new ScriptEngineManager();
        ScriptEngine engine=engineMgr.getEngineByName("JavaScript");
        Document doc=HtmlPage.getHTML("","C:\\Users\\DELL\\Desktop\\PHPTRAVELS.html","https://phptravels.com");
        String xpath="//input";
        
        //for single value
    /*  String jscript="return document.evaluate('"+xpath+"',document,null,XPathResult.FIRST_ORDERED_NODE_TYPE,null).singleNodeValue;";
        WebElement element=(WebElement)jse.executeScript(jscript);
        System.out.println(element.getattribute("name"));*/
        
        String multiCode="var test=function(document){"
                + "var results=document.evaluate('//input',XPathResult.ORDERED_NODE_ITERATOR_TYPE,null);"+
                "var tagNames = [];\r\n"
                + "var count=0;" +
                "while(node = results.iterateNext()) {\r\n" + 
                "  count=count+1;" + 
                "}"
                + "\r\n return count}";
        /*FileWriter fileWrite=new FileWriter(new File(System.getProperty("user.dir")+"\\jScript.js"));
        fileWrite.write(multiCode);
        fileWrite.flush();
        fileWrite.close();*/
        
        try{
            engine.eval(multiCode);
            Invocable invc=(Invocable) engine;
            Long count=(Long)invc.invokeFunction("test",doc);
        //Long count=(Long) jse.executeScript(multiCode);
        System.out.println(count);
        }catch(Exception e){
            e.printStackTrace();
        }
        }
