Built my first mobile app

<MeFromTheFuture>
At that time the term app was not even coined for software running on a mobile device.
Mobile device were more like PDA with the ability to phone.
Not enough memory, sluggish... To summarize: a constant struggle.

This application is a surveying tool to enter data regarding point of sales of a well-known company making coffee and coffee capsule.
What else!

Technically, it is running with the IBM J9 JVM and is powered by the SWT library.
I had to reduce the size of my executable so that the size of the software is installable on the PDA running Microsoft PocketPC.
It has offline capability and can be synced with the server through an HTTPS API. The protocol is custom to be lightweight.

Great fun to build it, but also some late nights to make things work.
