初始化Web容器时加载Servlet时加载server.xml里的数据源和

 jndi模式的 server.xml里的数据源：




  <Context path="/core" docBase="D:\hssoft\hsUnion\HSSMP\core" reloadable="true">
        <Resource name="jdbc/union" auth="Container" type="javax.sql.DataSource" 

driverClassName="dm.jdbc.driver.DmDriver" url="jdbc:DM://127.0.0.1:5236" 

username="SYSDBA" password="SYSDBA" maxActive="100" maxIdle="30" maxWait="10000" />
  </Context>








public class TestServlet extends HttpServlet {

 

    private static final long serialVersionUID = -8756437098790424507L;

    private final static String SERVER_CONFIG = "/conf/server.xml";


 

    public void doGet(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

        doPost(request, response);

    }

     

    public void doPost(HttpServletRequest request, HttpServletResponse response)

            throws ServletException, IOException {

        String config = System.getProperty("catalina.home") + SERVER_CONFIG;

        String jdbcName="union";

           

    }

     

    

}
