我在servlet上下文启动时通过以下代码在H2数据库中创建一个内存数据库

    void initDb()  {
    try {

        webserver = Server.createWebServer().start();

        Class.forName("org.h2.Driver");
        Connection conn = DriverManager.getConnection("jdbc:h2:mem:db1;DB_CLOSE_DELAY=-1","SA","");
        InputStream in = getClass().getResourceAsStream("script.sql");
        if (in == null) {
            System.out.println("Please add the file script.sql to the classpath, package " + getClass().getPackage().getName());
        } else {
            RunScript.execute(conn, new InputStreamReader(in));
            Statement stat = conn.createStatement();
            ResultSet rs = stat.executeQuery("SELECT TO_CHAR(bday,'DD/MM/yyyy hh24:mi') FROM TEST2");
            while (rs.next()) {
                System.out.println(rs.getString(1));
            }
            rs.close();
            stat.close();
            conn.commit();
            conn.close();
        }




    //accessed using url jdbc:h2:tcp://localhost/mem:db1    
    try{ 

                CachedRowSet crs = new DBConnector().executeQuery("select * from  test2"); 
                while(crs.next()){ 
                System.out.println("ARGUMENT_NAME:"+crs.getString(1)); 
               // System.out.println(",DATA_TYPE:"+crs.getString("DATA_TYPE")); …
