My code :

File file = new File(dirFileName);
        file.delete();
        file.createNewFile();
        DataOutputStream dataOut = new DataOutputStream(new FileOutputStream(file));
        dataOut.writeBytes(view);

Look at the error, is telling you that `dirFileName/home/bms/html/webversion/BzAEqwsEk20Fk21Pl30Qj33Ss26Aj17BcdDZrt.html` does not exist. Check if the path is correct. — Diogo Rocha, Oct 22 '15 at 10:48

This is orignal path and it exist **/home/bms/html/webversion/** the **dirFileName** is not attached with it its just printed using print statement — Fazeen Ahmad, Oct 22 '15 at 10:51
The exception message states that this directory path `/home/bms/html/webversion` does not exist on the machine where the Tomcat is running. — SubOptimal, Oct 22 '15 at 12:13

Two common problems that can lead to problems when transitioning from a dev machine(usually Windows) to a linux server are

-Case sensitivity. On a linux server tou should check that your paths are also valid case insensitive. Eg if tou have a folder in the filesystem named dirfilename and your java path is "dirFileName" this would work on windows but not on a linux server.

-File permissions. The jvm running your program could be run by a user that does not have permissions to the path you are trying to access. You can get more info on how a process is running using the 'ps aux' command.
