在eclipse添加db2的jdbc驱动，代码访问数据库在项目开发模拟器的时候需要一个比较好的版本控制软件，让几个人协同进行代码开发。同事给我推荐了svn。我用的eclipse3.4.1，带有svn插件，直接安装服务端阅读详情

import java.sql.*;
public class db2
{
public static void main(String args[])
{
Connection conn = null;
String url = "jdbc:db2:sample";
String user = "db2admin";
String pwd = "leipang";
try
{
System.out.println("\n Loading JDBC Driver ");
DriverManager.registerDriver(new COM.ibm.db2.jdbc.app.DB2Driver());
//Class.forName("COM.ibm.db2.jdbc.app.DB2Driver").newInstance();
System.out.println(" OK !");
}catch (Exception e)
{
System.out.println(" Failed !");
}
try
{
System.out.println("\n Connect to DB2 ");
conn = DriverManager.getConnection(url,user,pwd);
System.out.println(" OK!");
try
{
System.out.println("\n Create Statement ");
Statement stmt = conn.createStatement();
System.out.println(" OK !");
String sql = "select * from org";
try
{
System.out.println("\n Create ResultSet ");
ResultSet res = stmt.executeQuery("select * from org");
System.out.println(" OK !");
while (res.next())
{
System.out.println("\n" + res.getString(2));
}
}catch (Exception exce)
{
System.out.println(" Failed \n " + exce);
}
}catch (Exception exc)
{
System.out.println(" Failed !\n " + exc);
}

}catch (Exception ex)
{
System.out.println(" Failed !\n " + ex);
}
}
};
