一个初学者的困惑
问一下各位：一个tomcat的配置问题我的jdk是装在   d:\jdk1.5
tomcat装在   d:\tomcat   下
进入   http://localhost:8080     能够看到欢迎界面  
于是我又按照网上所说的那样在   D:\Tomcat\webapps   下建立了一个myapp目录，在此目录下又建立一个   index.jsp文件   和WEB-INF子目录，在WEB-INF目录下建了一个web.xml文件，这时我在浏览器中输入   http://localhost:8080/myapp/index.jsp
出现的页面出现以下文字：  

type   Exception   report

message

--------------------------------------------

Apache   Tomcat/5.0.28


这是怎么回事啊？我的环境变量如下：

CATALINA_BASE：   D:\Tomcat
CATALINA_HOME：   D:\Tomcat
TOMCAT_HOME:     D:\Tomcat
JAVA_HOME：   D:\jdk1.5
classpath：   .;d:\jdk1.5\lib\dt.jar;d:\jdk1.5\lib\tools.jar;D:\Tomcat\common\lib\servlet.jar;

path:   D:\jdk1.5\bin;%catalina_home%\bin
哪里弄错了吗？我谢谢大家了！




------解决方案--------------------
JAVA_HOME does not point to the JDK
path 里面添加 ％JAVA_HOME％\BIN
