TOMCAT
1.配置数据源（Tomcat 5.0\conf\server.xml）在</Host>添加

 <Context path="/tt" docBase="tt"
                 debug="5" reloadable="true" crossContext="true">
           <!--tt为部署工程的名称，在C:\Tomcat 5.0\webapps下-->
          <Logger className="org.apache.catalina.logger.FileLogger"
                  prefix="localhost_tt_log." suffix=".txt"
                  timestamp="true"/>

          <Resource name="jdbc/mysql"
                    auth="Container"
                    type="javax.sql.DataSource"/>
             <!--jdbc/mysql isjndi name-->
          <ResourceParams name="jdbc/mysql">
             <parameter>
                <name>factory</name>
                <value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
             </parameter>

             <!-- Maximum number of dB connections in pool. Make sure you
                  configure your mysqld max_connections large enough to handle
                  all of your db connections. Set to 0 for no limit.
                  -->
            <parameter>
              <name>maxActive</name>
              <value>100</value>
            </parameter>

            <!-- Maximum number of idle dB connections to retain in pool.
                 Set to -1 for no limit.  See also the DBCP documentation on this
                 and the minEvictableIdleTimeMillis configuration parameter.
                 -->
            <parameter>
              <name>maxIdle</name>
              <value>30</value>
            </parameter>

            <!-- Maximum time to wait for a dB connection to become available
                 in ms, in this example 10 seconds. An Exception is thrown if
                 this timeout is exceeded.  Set to -1 to wait indefinitely.
                 -->
            <parameter>
              <name>maxWait</name>
              <value>10000</value>
            </parameter>

            <!-- MySQL dB username and password for dB connections  -->
            <parameter>
              <name>username</name>
              <value>root</value>
            </parameter>
            <parameter>
              <name>password</name>
              <value>root</value>
            </parameter>

            <!-- Class name for the old mm.mysql JDBC driver - uncomment this entry and comment next
                 if you want to use this driver - we recommend using Connector/J though
            <parameter>
              <name>driverClassName</name>
              <value>org.gjt.mm.mysql.Driver</value>
            </parameter>
            -->
   
            <!-- Class name for the official MySQL Connector/J driver -->
            <parameter>
              <name>driverClassName</name>
              <value>com.mysql.jdbc.Driver</value>
            </parameter>
   
            <!-- The JDBC connection url for connecting to your MySQL dB.
                 The autoReconnect=true argument to the url makes sure that the
                 mm.mysql JDBC Driver will automatically reconnect if mysqld closed the
                 connection.  mysqld by default closes idle connections after 8 hours.
                 -->
            <parameter>
              <name>url</name>
              <value>jdbc:mysql://localhost:3306/mydb?autoReconnect=true</value>
            </parameter>
          </ResourceParams>
        </Context>
        <!--mydb数据库名-->
2. 修改web.xml

    打开%TOMCAT_HOME%\conf\web.xml,在</web-app>的前面添加以下内容：

     <resource-ref>
       <description>DB Connection</description>
       <res-ref-name>jdbc/mysql</res-ref-name>
       <res-type>javax.sql.DataSource</res-type>
       <res-auth>Container</res-auth>
    </resource-ref>

3. JDBC驱动程序mysql-connector-java-3.0.15-ga-bin.jar放置在%TOMCAT_HOME%\common\lib和应用的WEB-INF\lib下

在启动服务器前，把你的tt部署到C:\Tomcat 5.0\webapps
一切OK，启动你的猫猫
