我用的是myeclipse,在写一个很简单的swing的鞋业销售管理系统。界面代码是用插件拖出来的。

请问这是什么异常啊?
我通过堆栈信息,看到它指向的是我的jcombobox的setmodel方法那条语句。

找不到相应的方法。。。

java.lang.NoSuchMethodError: org.jvnet.lafwidget.LafWidgetUtilities.hasAutoCompletion(Ljavax/swing/JComboBox;)

找不到 hasAutoCompletion(javax.swing.JComboBox comboBox) 这个方法

------解决方案--------------------
是不是换了JAR的版本?
------解决方案--------------------
这是一个GUI线程的异常,是用来处理事件的,可能是你的那个触发事件有问题。
