J2SDK1.4.2+Apache Tomcat4.06+Oracle9i中的Tomacat的问题特急，请高手来看看，不胜感激~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

各位老兄，我现在有一问题：不知道什么原因，我JDK和Tomcat的环境都设置好了，并且程序在RESION下也能运行了，可能TOMCAT就是不行，老是报内部服务错误（Internal Server Error）。如下所示：type Exception report

message Internal Server Error

description The server encountered an internal error (Internal Server Error) that prevented it from fulfilling this request.

exception

实在是没办法了，请帮忙吧！

[bestdelphier]

首先你要将servlet包加到工程的lib目录下，其次你的字符串换行，必须每行都用""包裹起来，再次你的properties文件最好用相对路径。

[bboonnee]

没有调用到J2EE jdk中的jar包
需要设定参数路径或者将那几个包放在你的lib下

CLASSPATH的.jar包我放的有dt.jar,tools.jar,servlet.jar不知还需要什么呢？初次搞JSP，请多多包含呀！还有，路径的话，我感觉在这些是小问题，改过来就好了，还有： bestdelphier(Do What You Should Do) ，我想问一下，你这里说的相对路径是什么，我用的不是相对路径吗？只不过写法上有些问题吧，改成：FileInputStream fileln=new FileInputStream("%CATALINA_HOME%\\webapps\\NewPage\\WEB-INF\\classes\\mydb\\ifshowflow.properties");就成了吧，不过还是要谢谢你，我知道在这里用相对路径好一些，可在JSP里表达相对路径还不是很清楚，请明示一下好吗？
再次谢谢楼上的各位大虾们！
