你好，世界！
组合框不会作为其swing组件显示在浏览器中，但
代码将帮助你理解差异…试试看。。。
您能告诉我上述问题的解决方案吗
<body>
  <h1>Hello World!</h1>
     <%
       JFrame f;
       JComboBox cmbox;
       JPanel panel;


       //ComboBox b= new ComboBox();
       String course[] = {"BCA","MCA","PPC","CIC"};
       cmbox = new JComboBox(course);
       panel = new JPanel();
       panel.add(cmbox);
       //panel.setSize(400,400);
      //panel.setVisible(true);
       f=new JFrame("My Frame");
       f.add(panel);
       f.setSize(400,300);
       f.setVisible(true);
       %>

     </body>
      the combobox will not appear in the browser as its a swing component but this   

      code will help u understand the difference....try it...
