Tomcat6.0配置连接池连接SQL Server 2008数据库

1:在\apache-tomcat-6.0.18\conf中加入sqljdbc4.jar包，否则会所报org.apache.jasper.JasperException: java.lang.UnsupportedOperationException: Java Runtime Environment (JRE) version 1.6 is not supported by this driver.  Please use the JDBC 4 driver (sqljdbc4.jar) instead.
org.apache.jasper.servlet.JspServletWrapper.handleJspException(JspServletWrapper.java:522)
org.apache.jasper.servlet.JspServletWrapper.service(JspServletWrapper.java:416)
org.apache.jasper.servlet.JspServlet.serviceJspFile(JspServlet.java:342)
org.apache.jasper.servlet.JspServlet.service(JspServlet.java:267)
javax.servlet.http.HttpServlet.service(HttpServlet.java:717)

2:在你的项目里的META-INF里建一个context.xml文件，内容如下。

 <?xml version="1.0" encoding="UTF-8"?> <Context reloadable="true" crossContext="true">  <!-- Default set of monitored resources -->  <WatchedResource>WEB-INF/web.xml</WatchedResource>  <!-- Uncomment this to disable session persistence across Tomcat restarts -->  <!--   <Manager pathname="" />  -->  <Resource  name="jspjdbc/myDataSource"  auth="Container"  type="javax.sql.DataSource"  driverClassName="com.microsoft.sqlserver.jdbc.SQLServerDriver"  url="jdbc:sqlserver://localhost:1433;DataBaseName=express_yto"  username="sa"  password="skymusic"  maxActive="100"  maxIdle="30"  maxWait="1000"/> </Context> 3:打开WEB-INF下的Web.xml文件，加入如下代码： <resource-ref>        <description>DB Connection</description>        <res-ref-name>jspjdbc/myDataSource</res-ref-name>        <res-type>javax.sql.DataSource</res-type>        <res-auth>Container</res-auth>    </resource-ref>    4:写一个index.jsp测试一把 <%@ page language="java" import="java.util.*" pageEncoding="gb2312"%> <%@ page import="java.sql.*"%> <%@ page import="javax.sql.DataSource"%> <%@ page import="javax.naming.*"%>  <%      Connection con = null;      Statement stat = null;      ResultSet rs = null;      DataSource ds = null;      //从数据源连接池取得连接      Context ctx = new InitialContext();      if(ctx!=null){       ds = (DataSource)ctx.lookup("java:comp/env/jspjdbc/myDataSource");      con = ds.getConnection();                //查询数据表      stat = con.createStatement();      String sql = "select * from dict_sex";      rs = stat.executeQuery(sql);      //输出查询结果到页面      while (rs.next()){       out.println("<li>账号："+rs.getString(2).trim());       out.println("密码："+rs.getString(3).trim()+"</li>");      }      //关闭连接，释放资源      rs.close();      stat.close();      con.close();      }           %>
