Tomcat Servlet：错误404-请求的资源不可用

试试这个（如果是Java EE V6）

package crunch;import java.io.*;import javax.servlet.*;import javax.servlet.http.*;@WebServlet(name="hello",urlPatterns={"/hello"})public class HelloWorld extends HttpServlet {  public void doGet(HttpServletRequest request,         HttpServletResponse response)      throws ServletException, IOException {    PrintWriter out = response.getWriter();    out.println("Hello World");  }}

现在到达servlet

http://127.0.0.1:8080/yourapp/hello

其中8080​​是默认的tomcat端口，而yourapp是应用的上下文名称
