servlet kicking off a process

[So...@aol.com]

Hey I am sure this is basic question but first time I 've had to do it. Hope 
someone can help or refer me. I have a servlet that uploads a file, After the 
file is uploaded I want to start  a  process  that will read and parse the 
file and update the database. But since this process of reading parsing, and 
updating the DB may take a while, I want to display a JSP for the client 
immediately after the file has been uploaded. I was told whatever code is 
remaining after you call callPage is not executed. So is there anything 
special I have to do to display the page and have it read, parse, update in 
the background? Thanks
