我想知道如何從jsp調用JFrame。 當我點擊瀏覽器上的按鈕時,我想調用框架。 但我不知道該怎麼辦。 如果你不是我的,請解釋我。如何從JSP調用JFrame?

這是一些代碼!

} // @jve:decl-index=0:visual-constraint="294,19" 

我想從JSP調用該類。 謝謝。

JFrame不擴展Applet。 – EJP

不,我擴展了Applet,並且在這個類中使用了JFrame。 public ** class LoadFromStore extends Applet ** implements ActionListener { \t private static final long serialVersionUID = 1L; \t ** private JFrame frame = null; ** // @jve:decl-index = 0:visual-constraint =「369,9」 \t private JPanel contentPane = null; \t private JList lstCertificate = null; \t private JLabel jLabel = null; \t private JPasswordField password = null; \t private JButton btnLoad = null; \t private JLabel jLabel1 = null; –

當我點擊瀏覽器上的按鈕時,我想調用框架。

使用Java Web Start直接從HTML鏈接(或按鈕)啓動框架。
