Answer 2

出错：
C:\bea\user_projects\mydomain\applications\DefaultWebApp\html\PortResourceUsedApplet.java:133: cannot resolve symbol
symbol  : class ActionListener  
location: class com.sysway.resources.applet.PortResourceUsedApplet
        jButtonSearchDevice.addActionListener(((PortResourceUsedApplet)this). new ActionListener() {

Answer 3

没有输入错误，我想问这样写有错吗？
jButtonSearch.addActionListener(((PortResourceUsedApplet)this). new ActionListener() {            public void actionPerformed(ActionEvent e)
            {
                _$392001.jButtonSearch_actionPerformed(e);
            }        });
