Re: How to register actions programmatically with NetBeans Platform

You can remove all the null checks and getFolderAt() by:

String path = ...
FileObject root= FileUtil.getConfigRoot();
FileObject f = FileUtil.createData(root, path);

This creates the file including nonexistent parent folders if necessary 
(FileUtil.createFolder() does the equivalent for folders).
Generally the FileUtil class contains a lot of useful stuff.

Johannes
