你的url有错误.
你在jsp里面的action应该是 "/HelloWorldExample"
那个已经搞定了，现在是让我知道怎么编译servlet吧
<servlet-mapping>
<servlet-name>HelloWorldExample</servlet-name>
   <url-pattern>/servlet/HelloWorldExample</url-pattern>
</servlet-mapping> 你改成这样试试
我的HelloWorldExample.java的代码是：
/* $Id: HelloWorldExample.java,v 1.2 2001/11/29 18:27:25 remm Exp $
*
*/import java.io.*;
import java.text.*;
import java.util.*;
import javax.servlet.*;
import javax.servlet.http.*;/**
* The simplest possible servlet.
*
* @author James Duncan Davidson
*/public class HelloWorldExample extends HttpServlet {
    public void doGet(HttpServletRequest request,
                      HttpServletResponse response)
        throws IOException, ServletException
    {
        ResourceBundle rb =
            ResourceBundle.getBundle("LocalStrings",request.getLocale());
        response.setContentType("text/html");
        PrintWriter out = response.getWriter();        out.println("<html>");
        out.println("<head>");     String title = rb.getString("helloworld.title");     out.println("<title>" + title + "</title>");
        out.println("</head>");
        out.println("<body bgcolor=\"white\">"); // note that all links are created to be relative. this
// ensures that we can move the web application that this
// servlet belongs to to a different place in the url
// tree and not have any harmful side effects.        // XXX
        // making these absolute till we work out the
        // addition of a PathInfo issue     out.println("<a href=\"/examples/servlets/helloworld.html\">");
        out.println("<img src=\"/examples/images/code.gif\" height=24 " +
                    "width=24 align=right border=0 alt=\"view code\"></a>");
        out.println("<a href=\"/examples/servlets/index.html\">");
        out.println("<img src=\"/examples/images/return.gif\" height=24 " +
                    "width=24 align=right border=0 alt=\"return\"></a>");
        out.println("<h1>" + title + "</h1>");
        out.println("</body>");
        out.println("</html>");
    }
}
但是编译的时候却出现这样的错误：
HelloWorldExample.java:8: package javax.servlet does not exist
import javax.servlet.*;

HelloWorldExample.java:9: package javax.servlet.http does not exist
import javax.servlet.http.*;

这些错误都是因为你没有把SERVLET.JAR包导入你的SERVLET的工程中造成的。
你下载一个servlet2.3.zip放在jdk\lib下，然后用classpath指明路径就可以了
我告诉你最简单的办法：把tocmat\common\lib 下的servler.jar 文件copy 到你的
jdk的ext 目录下。如：D:\jdk\jre\lib\ext
谢楼主，谢林中静雪，the same problem has already done
方法一：环境变量 classpaht:%tomcat_home%\common\lib;%java_home%\lib;.;
上面的方法是如果你在环境变量里有tomcat_home 和java_home ；如果没有，你可以直接指定
比如：classpath c:\jdk\lib;.;c:\tomcat\lib\servler.jar方法二是：根据你刚才的回答，你说还不行，那你把这个servler.jar 放在C:\Program Files\Java\j2re1.4.2\lib\ext 下面，我想你的机器一定有这个目录，你试试吧！
