I created a small webapp that extracts data from a DB, creates an Excel file from that data (using Apache POI), which then streams the file to the end user's browser. Everything is working fine, however I have to set the Action class' return type to 'NULL' since I am setting the servlet response type to 'application/vnd-ms-excel'. I want to change my application so that it returns to a 'status completed' page when the extraction is completed. However I cannot do this when I set the return type is null. How can I do this?
