如何解决“构建成功”但“你好世界！”不显示 - NetBeans
我使用的是 Apache NetBeans IDE 12.1 和 JDK 8。我使用 Maven > Web 应用程序项目创建了一个 Java，其中包含两个包，ejb 和 web。 ejb 包有一个 AccountManager 和一个 AccountManagerLocal。
客户经理：
@Stateless
public class AccountManager implements AccountManagerLocal {
@Override
public String ping() {
return "ping";
}
}
AccountManagerLocal：
@Local
public interface AccountManagerLocal {
String ping();
}
我在web包中创建了一个Servlet：
@WebServlet(name = "AccountManagerServlet",urlPatterns = {"/AccountManagerServlet"})
public class AccountManagerServlet extends HttpServlet {
@EJB
private AccountManagerLocal accountManager;
protected void processRequest(HttpServletRequest request,HttpServletResponse response)
throws servletexception,IOException {
response.setContentType("text/html;charset=UTF-8");
try (PrintWriter out = response.getWriter()) {
/* Todo output your page here. You may use following sample code. */
out.println("<!DOCTYPE html>");
out.println("<html>");
out.println("<head>");
out.println("<title>Servlet AccountManagerServlet</title>");
out.println("</head>");
out.println("<body>");
out.println("<h1>Servlet AccountManagerServlet at " + request.getcontextpath() + "</h1>");
out.println("<h3>Result of ping()</h3>");
out.println("<p>"+accountManager.ping()+"</p>");
out.println("</body>");
out.println("</html>");
}
}
@Override
protected void doGet(HttpServletRequest request,IOException {
processRequest(request,response);
}
@Override
protected void doPost(HttpServletRequest request,response);
}
@Override
public String getServletInfo() {
return "Short description";
}// </editor-fold>
}
我只想运行整个项目 > 形象化“Hello World！”页面打开 > 然后运行文件 AccountManagerServlet > 可视化页面中的变化。
但由于某种原因，什么也没有发生。

我认为问题出在 GlassFish 上，但我不确定。我已经再次安装了 NetBeans，但问题仍然存在。有人可以帮我打开页面吗？
