TimeTable Mobile

TimeTable ME is a timetable platform written in J2ME, Java MicroEdition. It allows any train operators to easily create a portable schedule/timetable application that runs on any PDA/mobile devices supporting J2ME MIDP 2.0. Sample implementation contains the current schedule for CalTrain, the train system in San Francisco Bay Area.

Devices known to support MIDP 2.0:

• Symbian OS v7.0s+
• Palm OS 5.2+
• All Blackberry
• Windows CE/Mobile 5.0+
• Windows Mobile 2003 2nd Edition+

Windows devices will need IBM Micro Environment if it is not supplied by the phone manufactures.

How it looks:

1. Select a train schedule.

2. Select “From” and “To” stations and “AM/PM”.

Palm Blackberry

3. Matching timetables are displayed.

How it works:

SCREEN 1: The schedule names are read from .JAD file.
SCREEN 2: When a schedule is selected, the app attempts to read ${scheduleName}.txt from the JAR. The schedule has to be a TAB DELIMITED file in the following format.

Format of the schedule database:

Train No.	San Francisco	Milbrae	Mountain View	San Jose
422	8:00 AM			8:30 AM
424	8:15 AM	8:30 AM		8:45 AM
425	9:00 AM	9:15 AM	9:30 AM*	10:00 AM

• Time can be in 24hr format instead of AM/PM
• UTF characters are not yet supported.
• First column is ignored when the schedule is loaded.
• First row contain the stations names that will display on screen 2.

In the example above, 422 is a speed train connecting San Francisco to San Jose, 425 is a slow train stopping at every station. Please note the train stations MUST be in order of the direction of the train. In a Southbound timetable, the northmost station is listed first. The order is reversed for a Northbound timetable. Also, train number (row) MUST be ordered chronologically by time of departure.

How to create a new app using your train timetable

1. Edit your timetables into the format above.
2. Open up the .JAR file in the distribution with Winzip, delete *.txt and put your timetables in there.
3. Edit .JAD file in the distribtion (see configurable params below).
4. Update MIDlet-Jar-Size in the .JAD with the new .JAR size.

All devices:
1. Follow the instruction at the bottom of the page to set up your environment.
2. Format your timetables and put them inside the lib/schedule folder of the source
3. Edit .JAD file in the source.
4. Run Ant against the build.xml
