 UserName=sa
 Password= ***
 Driver=com.microsoft.sqlserver.jdbc.SQLServerDriver
我的代码是：
import   java.sql.*;   
import   java.util.*;   
import   java.io.*;   
import   javax.swing.*;   
public   class   Sqlconn   {   
    /**

    public   static   Connection   createConn()   {   
        try   {   
                                                Class.forName(driver);

                                            catch(NullPointerException   npe){ 
                                                return   dbConn;   
                                            }   
                                catch   (Exception   ex)   {   
                                                ex.printStackTrace();  
                                                return  dbConn;

                        }   
    public static Connection getConnection(){

return dbConn;
}
    public static Statement getStatement(){
Statement stmt = null;
try{
stmt =  getConnection().createStatement();
}catch(Exception ex){
ex.printStackTrace();
}
return stmt;
}
    public static void closeDbConn(){
if(dbConn!=null){
try {
dbConn.close();
} catch (SQLException e) {
e.printStackTrace();
}
dbConn=null;
}
}     private     static     boolean     init()   
      {   
              try   
              {   
                      Properties     properties   =   new   Properties();   
                      FileInputStream   fileinputstream   =   new   FileInputStream("src\\resource\\config\\DB.properties");   
                      properties.load(fileinputstream);   
                      fileinputstream.close();   
                      dataSource   =   properties.getProperty("DataSource");   
                      driver   =   properties.getProperty("Driver");

                      mesFlag=false;   
              }catch(FileNotFoundException   fnfe){   
                  JOptionPane.showMessageDialog(null,"没有找到注册应用数据库的配置文件，请检查！");   
              }   
              catch(IOException   ioEx)   
              {   
                      ioEx.printStackTrace();   
  
              }  
              return     true;   
      }   
  
}   
运行后出现的错误是

请问我的是什么错误？？谢谢回答！！

Answer 1

没有导入jar包。
数据库驱动包没有导入吧！

Answer 2

at yinshua.Cp_denglu$1.actionPerformed(Cp_denglu.java:69) 是界面类出错了吧,楼主怎么知道是数据库的问题,Cp_denglu.java 这个类贴出来看看

Answer 3

这个类出错的地方是：Statement h1=Sqlconn.createConn().createStatement();这句

Answer 4

Exception in thread "AWT-EventQueue-0" java.lang.NullPointerException
at yinshua.Cp_denglu$1.actionPerformed(Cp_denglu.java:69)
应该是你的Cp_denglu.java:69行的引用了空指针，具体原因不明，有可能是你数据库驱动的问题，也有可能是你代码的问题。你的数据库是不是sql-server2000？

Answer 5

Statement h1=Sqlconn.createConn().createStatement();
改成
Connection conn=Sqlconn.createConn();
Statement h1=conn.createStatement();
看看报什么错
