Tomcat连接池首次配置成功状态

环境:
jdk1.4 + Tomcat 5

一.环境变量：
PATH: C:j2sdk1.4.2in;
JAVA_HOME: C:j2sdk1.4.2
注:仅此两个.

二。SQL Server 驱动
COPY
Microsoft SQL Server 2000 Driver for JDBClib目录下三个.jar :
msbase.jar
mssqlserver.jar
msutil.jar
To
Tomcat5commonlib

三.虚拟目录与连接池
假设要在D:JsgTest建自己的虚拟目录
/myjsp
假设要建连接池jndi 名为aaa
假设连接数据库为pubs
则在
Tomcat5confCatalinalocalhost
目录下新建文件:
myjsp.xml

内容如下:

<?xml version='1.0' encoding='utf-8'?><Context crossContext="true" displayName="myjsp" docBase="D:/JsgTest" path="/myjsp" reloadable="true"> <Resource name="aaa" type="javax.sql.DataSource"/> <ResourceParams name="aaa">
<parameter> <name>url</name> <value>jdbc:microsoft:sqlserver://localhost:1433;DatabaseName=pubs</value> </parameter>
<parameter> <name>password</name> <value>kingapex</value> </parameter>
<parameter> <name>maxActive</name> <value>4</value> </parameter>
<parameter> <name>maxWait</name> <value>5000</value> </parameter>

<parameter> <name>driverClassName</name> <value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value> </parameter>
<parameter> <name>username</name> <value>sa</value> </parameter>
<parameter> <name>maxIdle</name> <value>2</value> </parameter>
</ResourceParams></Context>
测试:
在D:JsgTest目录下建文件:Test.jsp:
<%@ page contentType="text/html;charset=gb2312"%><%@ page import="java.sql.*"%><%@ page import="javax.sql.*"%><%@ page import="javax.naming.*"%><% Connection conn = null; Context initCtx = new InitialContext(); if (initCtx == null) throw new Exception("不能获取Context!"); Context ctx = (Context) initCtx.lookup("java:comp/env"); //获取连接池对象 Object obj = (Object) ctx.lookup("aaa"); //类型转换 javax.sql.DataSource ds = (javax.sql.DataSource) obj; conn = ds.getConnection();
Statement stmt = conn.createStatement(); String strSql = "select * from [titles]"; ResultSet rs = stmt.executeQuery(strSql); while(rs.next()){ out.println(rs.getString(1));
}
rs.close();stmt.close();conn.close();
out.println("连接池测试成功");%>
