jbuild怎么配置debug环境，急，在线等

[zhang520rui]

在jb的工程文件里我想单独运行一个java文件，但是由于其他文件里找到不到第三方的包，import org.apache.poi.hssf.usermodel.*;
import org.apache.poi.hssf.util.*;
import org.apache.poi.hssf.usermodel.contrib.*;

所以，我向运行我的java文件时，老是提示其他文件里缺少上面的包。
怎么能够debug我自己的java文件？在线等啊

在工程属性里面加进你需要的包

[xitianjile]

象jbuilder之类的东西，你没运行就会提示没有包了。

在工程的属性里导入你所需要的包。

怎么导入啊？我是jb新手啊。在属性的哪个页里

Tools-->Configure Libraries--->点New...-->(New Library Wizard)Name:(你自己命名),Location:默认-->点Add(选择你的jar)-->点OK-->点OK


或者
project->project properties->required libiaries->add

执行到String sql = "select us_dept from pm_user where us_login ='"+ user +"'";
try{

就出现了java.lang.NullPointerExcetion
大虾估计是什么原因那？
