若要支持数据库（以SQL Server为例）则为：
<Context path="/xkb" docBase="F:XKB6webApp" debug="5" reloadable="true" crossContext="true">
<Logger className="org.apache.catalina.logger.FileLogger" prefix="localhost_DBTest_log." suffix=".txt" timestamp="true"/>
<Resource name="jdbc/SqlServerDB" auth="Container" type="javax.sql.DataSource"/>
<ResourceParams name="jdbc/SqlServerDB">
<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>50</value>
</parameter>
<!-- Maximum number of idle dB connections to retain in pool. Set to 0 for no limit.-->
<parameter>
<name>maxIdle</name>
<value>20</value>
</parameter>
<!-- Maximum time to wait for a dB connection to become available in ms, in this example 0.5 seconds. An Exception is thrown if this timeout is exceeded. Set to -1 to wait indefinitely. -->
<parameter>
<name>maxWait</name>
<value>500</value>
</parameter>
<!-- msSQL dB username and password for dB connections -->
<parameter>
<name>username</name>
<value>sa</value>
</parameter>
<parameter>
<name>password</name>
<value>wangnewton</value>
</parameter>
<!-- Class name for SQLServer2000 JDBC driver -->
<parameter>
<name>driverClassName</name>
<value>com.microsoft.jdbc.sqlserver.SQLServerDriver</value>
</parameter>
<!-- The JDBC connection url for connecting to your MS SQL Server dB.The autoReconnect=true argument to the url makes sure that the mm.Sql Server JDBC Driver will automatically reconnect if mysqld closed the connection. mysqld by default closes idle connections after 8 hours.-->
<parameter>

<value>jdbc:microsoft:sqlserver://localhost:1433;databaseName=XKBCourse</value>
