我的任务
分享初哥提问，急！急！急！
如何使ＪＳＰ可以运行ＳＥＲＶＬＥＴ程序，上网看了很多文件说将commom/lib/servlet.jar目录修改进ＣＬＡＳＳＰＡＴＨ．但ＴＯＭＣＡＴ５．０没有了servlet.jar文件，应该怎么办？
还有当我编译以下这个简单的Servlet程序的时候出现以下错误！
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
public class HelloWorld extends HttpServlet {
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws IOException, ServletException
{
response.setContentType("text/html");
PrintWriter out = response.getWriter();
out.println("<html>");
out.println("<head>");
out.println("<title>Hello World!</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Hello World!</h1>");
out.println("</body>");
out.println("</html>");
}
}
package javax.servlet does not exist
package javax.servlet.http does not exist
cannot find symbol
该怎么解决这个问题～！！！
请高手门帮忙一下
