JDNI数据库有没有配好啊,找不到数据源吧

数据源最好写成
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup("yourDataSourceName");
Connection conn = ds.getConnection();
就算你要把2和3两句合并那也应该是
DataSource ds = (DataSource)ctx.lookup("java:/comp/env/jdbc/bookstore");
少了一个/

你的路径java:comp/env/jdbc/bookstore找不到
