To learn j2ee should first learn j2se, just beginning to learn j2se first IDE is not recommended, and then gradually transition to IDE development, after all, it is convenient thing. Learn j2se recommend two books, "java2 a core technology vols", "java programming ideas", "java model." Where "java programming ideas" to study, intensive reading.
