my NetBeans has ugly fonts in interface. I\'m going to make antialiasing for it. In internet I saw that there is should be
-J-Dswing.aatext=true -J-Dawt.
On an ubuntu platform you can use the following command
locate netbeans.conf
to find where the netbeans files are located. It's the best way that provides with a precise location of your netbeans.conf file.
Hope this will help someone in need.
