Linux环境下iPlanetWebServer6SP5支持JSP问题

东北大灰狼

RedHatLinux7.1\iPlanetWebServer6SP5\Mysql现在要支持JSP，在iPlanet的管理页面下按照Sun的文档配置了相应的DocumentRoot\JVMClasspath，编辑了Web-app.xml。系统的环境变量。写了一个test.jsp里面system.out("hello"可以正常解析并显示。把整个论坛系统放到目录下面，输入相应URL后显示“无法显示网页”错误。查看WebServer的Logs显示如下：

请注意下面的：

后来又把tools.jar加入到JVMClasspath中。还是不行。上Sun的网站看了相关的文档、管理员手册，根据上面说的作。问了几个作开发的朋友，还是没能成功。
谁有什么好主意看看我下一步应该怎么做！
谢谢！

看看这一段

这段我昨天注意到了，可是看了几遍。我能理解到的就是怀疑缺少相应的类文件。当时又不知道具体缺少哪个。也不知道自己想的方向对不对。请大侠指教！
