See if that works. You may change the time to at least see if it runs
correctly so you don't have to wait until 4:30 :)
As Great Buckets of Spam noted, that won't work because there's no
display available.
Writing a GUI application to do interval-based work doesn't seem to me
the best idea, but now it's done here are some ideas.
1.
vnc
vnc has the ability to run an X session without the user being logged
in. The idea is that the user will connect some time (maybe but not
necessarily using a Java-capable browser) to do some work. I could
almost certainly run your application that way, providing we can agree a
way to close it down. It wouldn't be interactive though.
2.
This might include the use of vnc.
Some calendar applications can run specific programs at set times. I
used to use one on OS/2 - it was a standard program that came with OS/2
Warp. If you don't have a calendar that supports this, then you could
build the scheduling into the application (it might simply test for the
presence of a file every little while and rely on an external agent such
as cron to create that file in a private place) and start it on boot in vnc.
I think displaying on an existing session (which might not exist; and
which, in a multiuser environment could belong to almost anyone) is
inherently bad.
