网页上的Applet显示不出来,总是在JAVA控制台上报错NoClassDefFund

[hazuki_ryo]

我在JBOSS4.0.4环境下用一个网页上的Applet来进行打印,以前这个打印Applet用的是jasperreport0.5.2,这次想把它更新成2.0.1,但是更新了applet文件的所有包路径之后编译再放到原来的地方后,这个applet就一直显示不出来了,查看java控制台,报了java.lang.NoClassDefFoundError: PrinterApplet (wrong name: com/wancheng/applets/PrinterApplet)

这样的错.
一开始以为是文件中写了package才会报错,但是后来去掉这条后再编译还是报这个错,我已经被这个applet逼得快崩溃了,请大家帮帮我吧

应该是路径错误
