This requires a lengthy response, so I'll refer  you to an article that goes through one method of how to do this.

I'm not sure if Fedora uses the same mechanism as Debian/Ubuntu, but on those systems, you can set up defaults for new users by copying the relevant .gnome and .kde directories from a working user account to /etc/skel. This would give new users the same default configurations as the user from which you copied the directories from. Again, this only applies to newly created users.

Not that I know of, short of copying the .kde and .gnome folders from a reference user to all other users, which would change all gnome and kde settings. I don't know of a way to just change a file type association or similar. Perhaps if you could find the specific config file that contains the setting, you could grep through all the users' home folders and manually make the change from the command line or with a quick sed script.

with the help of URL

in KDE using ControlCenter-->KDEComponents-->FileAssociation

while doing i noticed that this process will create 3 files
in respective directory


where "" is my Shell script file which will run my jar
where "caux." is my extension
profilerc is settings file which store the link information

these above three files are created when i use ControlCenter and it work fine for me...

to avoid manual work what i did is i have created a 3 files in respective path programitically using java here it is not working

my question is is thier any thing that i am missing to update are create programmatically

To create files the code written in java
