【问题描述】:
尝试将简单的 servlet 部署到 Tomcat 服务器。选择Run Tomcat... 后,我被重定向到http://localhost:8080/hi_war_exploded/,网页只有一个字-$END$。日志文件没有报告错误。
我希望在tc9\webapps 中看到带有我的应用程序的hw 文件夹,但什么也没找到。
$END$ 是什么意思?我在TomCat 服务器上的应用程序在哪里?如何将我的 servlet 放到 TomCat 服务器上?
小服务程序:
import java.io.*;
import javax.servlet.*;
import javax.servlet.http.*;
// Extend HttpServlet class
public class hw extends HttpServlet {
private String message;
public void init() throws ServletException {
// Do required initialization
message = "Hello World";
}
public void doGet(HttpServletRequest request, HttpServletResponse response)
throws ServletException, IOException {
// Set response content type
response.setContentType("text/html");
// Actual logic goes here.
PrintWriter out = response.getWriter();
out.println("<h1>" + message + "</h1>");
}
public void destroy() {
// do nothing.
}
}
