3，配置新的webApp：找到host尾标记< /Host>，插入新的context即可。
如：
（1）< Context path="" docBase="ROOT" debug="0"/>
若要支持数据库（以SQL Server为例），则为：
（2）< Context path="/xkb" docBase="F:\XKB6\webApp" 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">
