有谁在JBuilder 2005下调过JDK1.5的DEMO(SwingSet2)

兄弟们，帮帮忙了！

想不到调个DEMO也这么烦的，原来还指望调过了再学习代码，却料想不到冒出N多的问题！

有的DEMO做的还不错，学习学习！！！

[zhuaibing]

诸位有兴趣的可以试试啊！！！！

这个错误已经解决！谢谢gtlang78，DEMO调试通过！

但是还有这个错误警告提示："DirectionPanel.java": [deprecation] isFocusTraversable() in java.awt.Component has been deprecated at line 162, column 9
该如何去掉？是不是有这个警告也无所谓？

刚才发现DEMO虽然调试通过，但是发现这些错误：

相关代码如下：
void loadDemo(String classname) {
setStatus(getString("Status.loading") + getString(classname + ".name"));

DemoModule demo = null;
try {
Class demoClass = Class.forName(classname);
Constructor demoConstructor = demoClass.getConstructor(new Class[]{SwingSet2.class});
demo = (DemoModule) demoConstructor.newInstance(new Object[]{this});
addDemo(demo);
} catch (Exception e) {
System.out.println("Error occurred loading demo: " + classname);
}
}

[jackyzhu_001]

使用了package
Class demoClass = Class.forName("test."+classname);

[gtlang78]

你得把资源文件也拷过去才能运行，就是SwingSet2.jar包里的resources目录，把这个目录解压出来和你的源程序放在一起。
