Answer 1

There is no specific reason that a JSP cannot write a properties file. If it is not working and there are no apparent errors, then I suspect:

• the properties file is really being written, but not in the directory you are expecting it to be written,
• you have configured your logging to suppress error messages, or
• you are looking for errors in the wrong place.

IMO, the first is the most likely, especially if you are providing a relative pathname for the properties file. (If you instantiate a FileOutputStream using a relative pathname, it will be resolved relative to the web server process's "current directory" ... which may not be where you think it is.)

Answer 2

How did you define where you write your file ? Absolute or relative path ?

May be when you test your class you can write but when you test your jsp the location use the server location ?

Display the path in your jsp to check where it writes.
