帮忙看看这段代码是如何连接数据库的?
Connection conn = null;
DataSource pool = null;
Statement stmt = null;
try {
Context env = (Context) new InitialContext().lookup("java:comp/env");
pool = (DataSource) env.lookup("jdbc/oracle");
if (pool == null)
throw new ServletException("`jdbc/oracle' is an unknown DataSource");
conn = pool.getConnection();
stmt = conn.createStatement(ResultSet.TYPE_SCROLL_SENSITIVE,ResultSet.CONCUR_UPDATABLE);
}
