我的tomcat的环境变量配置如下：
JAVA_HOME：C:\Program Files\Java\jdk1.6.0
CATALINA_BASE：E:\Tomcat 5.0
CATALINA_HOME：E:\Tomcat 5.0
TOMCAT_HOM：E:\Tomcat 5.0
path：C:\Program Files\Java\jdk1.6.0\bin
classpath：.;%JAVA_HOME%\lib\dt.jar;%JAVA_HOME%\lib\tools.jar;.;%JAVA_HOME%\lib\dt.jar; %JAVA_HOME%\lib\tools.jar;%CATALINA_HOME%\common\lib\servlet-api.jar
我测试jsp文件时，没有问题，但是测试servlet时总是报错，以下有一个例子：
fromHtml.html 此文件放在root目录下，如下:
<html>
<head>
<title>
a form html example
</title>
</head>
<body bgcolor= "pink ">
<form action= "/doget " method= "get ">
input you name: <input type= "text " name= "myname "> <br>
your loves: <select name= "love ">
<option value= "sleep "> Sleep </option>
<option value= "dance "> Dance </option>
<option value= "travel "> Travel </option>
</select> <br>
<input type= "submit " value= "hand " name= "submit ">
<input type= "reset " value= "reset " name= "submit ">
</form>
</body>
</html>
下面的是servlet文件
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class doForm extends HttpServlet
{
public void doPost(HttpServletRequest req,HttpServletResponse res)throws ServletException,
IOException
{
res.setContentType( "text/html ");
PrintWriter out=res.getWriter();
out.println( " <html> <head> </head> <body> ");
out.println( "name: "+req.getParameter( "myname "));
out.println( " <br> ");
out.println( "love: "+req.getParameter( "love "));
out.println( " </body> </html> ");
out.close();
}
public void doGet(HttpServletRequest req, HttpServletResponse res)throws ServletException,
IOException
{
doPost(req,res);
}
}
这个文件己经编译过了，而且没有问题，我把它的类文件放在了E:\Tomcat 5.0\webapps\ROOT\WEB-INF\classes目录下．
并且我修改了在
E:\Tomcat 5.0\webapps\ROOT\WEB-INF下的web.xml文件：在 <wed-app> 标签之间添加了以下代码：
<servlet>
<servlet-name> a </servlet-name>
<servlet-class> doForm </servlet-class>
</servlet>
<servlet-mapping>
<servlet-name> a </servlet-name>
<url-pattern> /doget </url-pattern>
</servlet-mapping>
但是通过浏览器访问http://localhost:8080/fromHtml.html
后，在表单中填写信息以后，提交后：
tomcat 出现如下的报错信息：
HTTP Status 404 - /doget
--------------------------------------------
type Status report
message /doget
description The requested resource (/doget) is not available.
