昨天看到一篇《纯JSP分页代码 》的文章，是用于mysql，稍微修改下，用于Sqlserver2005/2008，没有异常处理。没有考虑性能等。
现将代码贴出，以供初学者参考：
注：邀月使用环境Eclipse 3.4.2+Tomcat 6.18+Sqlserver2005 sp3调试成功。
页面pagelistDemo.jsp内容：

用到的类文件：Globals.java
/** * */ package net.data.util; /** *//** * @author Administrator * */ public class Globals { public static String username="sa"; public static String pwd="sa"; public static String DbName="TestData"; //public static String Server="192.168.30.6"; public static String Server="192.168.44.2:1433"; public static String Port="1433"; public static String driverName="com.microsoft.sqlserver.jdbc.SQLServerDriver"; // public static String connectionURL { // // return "jdbc:sqlserver://"+Server+":"+Port+";databaseName="+DbName; // } } <!-- {cps..1}-->/***/ /** * */ package net.data.util; /***/ /** * @author Administrator * */ public class Globals { public static Stringusername = " sa " ; public static Stringpwd = " sa " ; public static StringDbName = " TestData " ; // publicstaticStringServer="192.168.30.6"; public static StringServer = " 192.168.44.2:1433 " ; public static StringPort = " 1433 " ; public static StringdriverName = " com.microsoft.sqlserver.jdbc.SQLServerDriver " ; // publicstaticStringconnectionURL{ // // return"jdbc:sqlserver: // "+Server+":"+Port+";databaseName="+DbName; // } }
效果如图：
