servlet的配置问题，我安装了jdk1.3

import javax.servlet.*;
import javax.servlet.http.*;

import java.io.*;
public class helloworld extends HttpServlet
{

public Void doGet(HttpServletRequest req,HttpServletResponse res)
throws ServletException,IOException
{
res.setContentType("text/html");
PrintWriter out=res.getWriter();
out.println("<HTML>");
out.println("<HEAD>");
out.println("<TITLE>Hello Word SampleServlet</TITLE>");
out.println("</HEAD>");
out.println("<BODY>");
out.println("<CENTER><H1>Hello World!</H1></CENTER>");
out.println("</BODY>");
out.println("</HTML>");
out.close;
}
}


编译javax.servlet.*不存在
