Answer 1

how can i close the pop up window in servlet and redirect the servlet to parent window.

You cannot do this from the servlet side on. You have 2 options:

1. Just do not call the servlet from the popup window, but from the parent window. The popup window should basically only contain some additional data or info and always be closed by JavaScript when it has done its job. The enduser should continue navigating/submitting from the parent window.

2. Let the servlet return a piece of JS code which does roughly the following:

    window.opener.location = 'newpage.jsp'; // Sets parent window's new URL. window.close(); // Close the popup window. 

   This is however an ugly hack.

Answer 2

传递到servlet回调方法（javascript），该方法将关闭弹出窗口并在父窗口中处理响应。
