1、下載proxool 地址： http://proxool.sourceforge.net/download.html
??? 2、解壓縮proxool-0.9.0RC2.zip，拷貝lib/proxool-0.9.0RC2.jar到web-info/lib
??? ?? 拷貝jdbc驅動到web-info/lib
??? 3、在web-info下建立文件：proxool.xml
???? 文件內容如下：
<?xml?version="1.0"?encoding="ISO-8859-1"?>
<something-else-entirely>?
<proxool>????
????<alias>kc</alias>????
?????<driver-url>jdbc:microsoft:sqlserver://jifeng:1433;databasename=yao;</driver-url>?
????<!--<driver-url>jdbc:microsoft:sqlserver://localhost:1433;databasename=kc;</driver-url>-->
????<driver-class>com.microsoft.jdbc.sqlserver.SQLServerDriver</driver-class>????
????<driver-properties>??????
????????<property?name="user"?value="sa"/>??????
????????<property?name="password"?value=""/>????
????</driver-properties>????
????<maximum-connection-count>10</maximum-connection-count>
????<house-keeping-test-sql>select?CURRENT_DATE</house-keeping-test-sql>????????????
</proxool>
</something-else-entirely>
??? 4、在web.xml文件內加入以下內容：

????<servlet>
????????<servlet-name>ServletConfigurator</servlet-name>
??????????<servlet-class>org.logicalcobwebs.proxool.configuration.ServletConfigurator</servlet-class>
??????????<init-param>
????????????<param-name>xmlFile</param-name>
????????????<param-value>WEB-INF/proxool.xml</param-value>
??????????</init-param>
??????????<load-on-startup>1</load-on-startup>
????</servlet>
<!-- proxool提供的管理監控工具，可查看當前數據庫連接情況。如果運行不成功，請刪除本行 -->
? ????<servlet>
??????????<servlet-name>Admin</servlet-name>
??????????<servlet-class>org.logicalcobwebs.proxool.admin.servlet.AdminServlet</servlet-class>
????</servlet>
???????????????????????????????????????????????????????????????????????????????
????<servlet-mapping>
??????????<servlet-name>Admin</servlet-name>
??????????<url-pattern>/admin</url-pattern>
????</servlet-mapping>

???? 5、在調用數據庫連接代碼：
import?java.sql.*;
import?javax.sql.*;
import?javax.naming.*;
import?org.logicalcobwebs.proxool.configuration.*;

public?class?Pool
...{
?????/**?*//**
?????*?得到數據庫的連接.
?????*?@throws?Exception?Pool:getConnection()--連接池獲得連接出錯
?????*/
?????public?static?Connection?getConnection()?throws?Exception
????...{
????????//Class.forName("org.logicalcobwebs.proxool.ProxoolDriver");
????????//PropertyConfigurator.configure("proxool.properties");
????????//JAXPConfigurator.configure("proxool.xml",?false);?
????????try
????????...{
????????????Connection?conn?=?DriverManager.getConnection("proxool.kc");
????????????return?conn;
????????}
????????catch(Exception?e)
????????...{
????????????throw?new?Exception("Pool:getConnection()--連接池獲得連接出錯,請才web.xml文件中配置初始化參數。"+e.getMessage());
????????}????????
????}?
}

???? 6、利用proxool監控工具查看數據庫運行狀態。地址：./admin
