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.
