刚用netbeans 。。遇到了些很奇怪的问题。不知道如何解决。。帮忙看下。。

Question

我的一个系统，以前是myEclipse开发的，现在我把它导入到NetBeans中。开始遇到了一些找不到form中的get/set 方法问题，后来我把form中的get/set都删了，又重新生成了一遍，问题解决了。但现在又来一个问题。。就是下面的。。。编译期没有任何问题。这是运行时页面报出的错误。
java.lang.Error: Unresolved compilation problems:

The import java.util.Iterator cannot be resolved

请问这是为什么？似乎是环境变量的问题？可是我的环境变量都配置了啊。。

谢谢你的回答 。。我在NetBeans下面又建了一遍工程。。。这样给搞定了。。。

Answer 1

这是因为在netbean工程中,你没有导入错误中提示的相关jar包,你导入那些相关的jar包,或者把它们加到classpath中去.

另外一个方便的做法就是你新建一个web工程,然后把原先工程的相关代码copy到你新建的工程中来,这样也行的.
