是的，jsp有错误，\65293和getServletContext。

javac运行后很正常！出现javac的帮助命令！
我现在正在重装一个win98去试一下！

不是例子的问题，是你的环境配置的问题。你的Weblogic是在你的用户名下运行吗？在Windows命令行下运行命令javac，出现什么？

javaxbenz 2002-05-22
CLASSPATH设置有问题
jimjxr 2002-05-21
weblogic找不到你的javac.exe，把你的JDK下面的bin目录加入PATH。
rosmada 2002-05-21
这个页面好像没用到bean啊，不过错误好像和bean有关，是不是你的相关jsp文件里的.java有没有解释成.class文件啊？我也不太清楚，java.io.IOException: 是没有导入还是执行没有成功呢？对不起我也是小菜一个，不过倒是挺热心！！^_^

编译器肯定没有问题，你还是好好看看你的程序代码吧。我现在用的是jrun，一点问题都没有！

呵呵，书上的例子一般都没有错的，可能是你的环境或路径有问题。

我加了path并把低版本的jdk去除但还是不行，
我是用的一个书上的例程作为学习的例子的，如果可以我把它发给你
帮我看一下，我一定给分的！如何？谢谢！
