I will be honest and admit that I have not been SQL Developers biggest fan since it's release a few years ago. Having always used 3rd party products such as TOAD and PL/SQL Developer, I found certain things a little irritating and not overwhelmingly obvious when forced to use SQL Developer.
Recently however, I found an absolute god send of a feature in SQL Developer and that was the ability to import / export APEX applications. This means that the Web GUI for such actions is no longer required.
Very simply, you connect to your parsing schema's database account via SQL Developer, right click on the Application Express tree directory and select Import Application. This opens a simple wizard and off you go.
One other cool feature of this is that you can open the details window and see exactly what your import is doing, something that is not possible when using the web GUI.
