求教SWING高手!

Question

我找了个万能打印的模块，
他用的是UIManager.setLookAndFeel(UIManager.getSystemLookAndFeelClassName());
把他风格改成
UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");
就报错了，不知道怎么回事；
懂SWING的帮我解决呀

UIManager.setLookAndFeel("com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel");改成
UIManager.setLookAndFeel(com.sun.java.swing.plaf.nimbus.NimbusLookAndFeel);
