netbean6.5新建桌面应用程序出错

我用netbean6.5建立了一个项目名称为VE的桌面应用程序，里面默认有三个java文件：VEApp.java;VEaboutBox.java;VEView.java，我什么都没做，直接编译运行VEApp.java，却总是提示如下错误：

1、请问这个问题该如和解决？
2、在VE项目中，新建JFrame窗体，往JFrame窗体中添加的控件在预览时能现实，运行后就显示不了字体了，比如，我添加一个名字为“确定”的JButton，预览时能够正常显示，可运行后只能显示有这个按钮，却显示不了按钮上面的字体，请问这该如何解决？
我自己没有添加任何代码，建立的“桌面应用程序”是netbean6.5自动生成的那个状态，代码我没动过。

Answer 1

你用的JDK什么版本?最新的1.6.0update12和NetBeans是有冲突的,如果是请降级用1.6.0update11以下的

Answer 2

(VEView.java:31行 空指针了.
