I have an icon for excel download on a jsp page. On clicking the icon I disable the icon and a request is made to a struts action to create an excel using HSSF. The content disposition is set as attachment with a filename and the bytes of the HSSFWorkbook is written to the response. The action forward returned is null. I want to enable the icon once the struts action has performed the creation and writing bytes to response. Is there a way to inform the jsp with the icon that the request for the excel generation has been completed and a dialog box has been opened for save/open excel? I need this so as to enable back the icon.
Reasonable people adapt themselves to the world. Unreasonable people attempt to adapt the world to themselves. All progress, therefore, depends on unreasonable people.
