上网找了半天,也没找见解决方法,最后只好自己检查了,最后发现是djk的原因,项目是weblogic8.13+jdk1.4,前天吧,我因为做一个线程的程序,把eclipse的jdk改成1.5了,不过我只是改那个项目的jdk而没有改整个eclipse的编辑环境的,不过我却发现在eclipse的设置(eclipse-window-preferences-java-compiler里的complier compliancelevel)中,编辑默认的却改成了5.0,我把这个改成1.4,重现编辑程序,启动webloigc,ok,错误没有了,一切正常.
    我以前知道weblogic8系列的不知道jdk1.5,但在编辑默认改成5.0以前却是没有遇到,真是烦人,我个人是比较喜欢jdk1.5,因为有些方法做的比较好,做程序的时候可以少写不少代码,但没有方法,用weblogic8系列的,只能用1.4.
