谁能解决？？？？？？？
| 新手问题，但谁能帮忙解决？（有关JSP配置） |
系统是：
Microsoft Windos Server 2003 Enterprise Edition
JDK是：j2sdk-1_5_0-beta-windows-i586.exe
Tomcat是：jakarta-tomcat-5.0.28.exe（安装的时候 我选择“Full”安装 JVM路径
为：C:\Program Files\Java\j2re1.5.0\bin\client\jvm.dll）
安装路径：D:\j2sdk1.5.0和D:\Tomcat 5.0
下面是配置信息：
CATALINA_BASE D:\Tomcat 5.0;
CATALINA_HOME D:\Tomcat 5.0;
JAVA_HOME D:\j2sdk1.5.0
ClassPath .;D:\j2sdk1.5.0\lib\dt.jar;D:\j2sdk1.5.0
\lib\tools.jar;D:\j2sdk1.5.0\jre\lib\rt.jar;D:\Tomcat 5.0
\common\lib\servlet-api.jar;
Path D:\j2sdk1.5.0\bin;
=================================
1.到Tomcat的安装目录的webapps目录；
2.在webapps目录下新建一个目录，起名叫myapp；
3.myapp下新建一个目录WEB-INF，注意，目录名称是区分大小写的；
4.WEB-INF下新建一个文件web.xml，内容如下：
<?xml version="1.0" encoding="ISO-8859-1"?>
<!DOCTYPE web-app
PUBLIC "-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
" http://java.sun.com/dtd/web-app_2_3.dtd";>
<web-app>
<display-name>My Web Application</display-name>
<description>
A application for test.
</description>
</web-app>
5.在myapp下新建一个测试的jsp页面，文件名为index.jsp，文件内容如下：
<html><body><center>
Now time is: <%=new java.util.Date()%>
</center></body></html>
6.重启Tomcat
7.打开浏览器，输入:http://localhost:8080/myapp/index.jsp
错误信息：
HTTP Status 500 ------------------------------------

=============================
为什么回这样？为什么org.apache.jasper.JasperException: Unable to compile class for JSP和Unable to find a javac compiler;com.sun.tools.javac.Main is not on the
classpath.Perhaps JAVA_HOME does not point to the JDK？请问：为什么不能运行？（在测试http://localhost:8080/的时候已经出现小猫了） |
