I have java web app.
(我有Java Web应用程序。)
In my .jsp page the user can click eg a button which calls a java servlet (maybe with ajax or not). (在我的.jsp页面中，用户可以单击例如一个按钮，该按钮调用Java servlet（可以使用ajax，也可以不使用ajax）。)
The servlet takes a few minutes to complete the task. (Servlet需要几分钟来完成任务。)
During the completion the user is on a different page. (在完成过程中，用户位于其他页面上。)
How can I show maybe with a alert the response of the servlet in the other page. (如何在另一个页面中通过警报显示servlet的响应。)
Best regards and thanks.
