tomcat5 连接池配置错误，高手指点！！！

conf\Catalina\localhost下新建一个yourapp.xml文件
加上
<Resource name="jdbc/sa" type="javax.sql.DataSource"/>
     <ResourceParams name="jdbc/sa">
      <parameter>
        <name>maxWait</name>
        <value>5000</value>
      </parameter>
      <parameter>
        <name>maxActive</name>
        <value>4</value>
      </parameter>
      <parameter>
        <name>password</name>
        <value>sa</value>
      </parameter>
      <parameter>
        <name>url</name>
        <value>jdbc:microsoft:sqlserver://192.168.0.2:1433;DatabaseName=pubs</value>
      </parameter>
      <parameter>
        <name>driverClassName</name>
        <value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
      </parameter>
      <parameter>

      </parameter>
      <parameter>
        <name>username</name>
        <value>sa</value>
      </parameter>
    </ResourceParams>
在yourapp\web-inf\web.xml 加
 <description>MSSql server Test App</description>
 <resource-ref>
     <description>DB Connection</description>
     <res-ref-name>jdbc/sa</res-ref-name>
     <res-type>javax.sql.DataSource</res-type>
     <res-auth>Container</res-auth>
 </resource-ref>
