找不到taskdef类com.sun.javacard.ant.tasks.ConverterTask

我使用netbeans中的java卡开发工具包2.2.1创建示例项目。 我的代码是这样的，我遵循教程

我的build.xml就在这里

我清理并生成了我的项目，发现了以下错误：“C:\Users\BRI\Documents\NetBeansProjects\TestApplet02\build.xml:81:taskdef class com.sun.javacard.ant.tasks.ConverterTask找不到

使用类加载器AntClassLoader[]。我该怎么办？请帮帮我…

我想那个教程已经过时了。您可以为初学者尝试一种简单的方法，它是一种简单易懂的ant build.xml工具，适用于任何IDE。
