Yes all those computers are having ftp access.Do I need to configure my webserver for accesing data on those machines for reading files on those machines or IP addresses.How to do it? Give some example.Like my web application is deployed on the webserver using JSF on Netbeans with Visual Web Pack.How to access the files in the specified directories on those machines simultaneously like my web application should be able to fetch data from the files on those machines after every 2 secs and upload that data to the database.
