请问如何使一些例程在jb9编译运行成功？(100分)

有一些书本上的例程每个源程序都有一行package com.xxx.yyy.zzz之类的;
请问怎么使这些程序适应jb9？
我在jb9新建一个project，然后加入这些源文件，编译运行有一大堆异常。

package com.xxx.yyy.zzz 这是用来定义包名的，
在你新建的工程中用
import com.xxx.yyy.*;
//这句可以把别人定义的包中所有的类加载进来。如Delphi的uses SysUtils;功能一样。当然在使用之前必须保证对方的类已经被编译并加入路径中了。

JBuilderX新增了一个功能，从现有代码建立工程文件，能够解决你的问题。
以前的版本比较麻烦一点，新建工程文件，在src目录中按包的层次建立子目录，例如，/src/com/xxx/yyy/zzz

我是完全没有自己的文件，那import com.xxx.yyy.*;
应该写在哪呢？

将你的异常贴出来些吧。

在jb9先new一个project
然后add files，将一些例程加入。
最后make project
错误信息如下：

我下了个jbx，请问如何在jbx下从现有代码建立工程文件？

jbx 在哪儿下？

www.borland.com

to yijin:
File-New-Project-Project for Existing Code
输入现有代码所在的目录和工程文件名就行了。

我用wizzard->import source好象也可以，请问是吗？

多人接受答案了。
