Overview:

This API provides Object Oriented Mappings over J2ME’s standard RMS
Features:

• Developed on j2me-wtk and Nokia Series 60, testing on Nokia 3650
• MIDP 1.0, CLDC-1.0 Compliant, i.e. can be used on any kind of J2ME device

• Support for all J2ME primitive data types and their class representations
• Support for Vector which contains any of the supported types / classes
• Support for pseudo-floating point (MIDP1.0 has no float)
• Support for any class implementing the persistence interface
• Filters, Searchers, and sorters can be applied at retrieval time

Status:

• In production and being used in my other projects
• May not give full performance on phones with slow processors
• May not be an optimal solution on phones having limit on RMS size or low memory

TODOs:

• Write a benchmark program and publish results

Overview:

Currently un-named, its goal is to provide a chart drawing package based on MIDP 1.0 specifications. Another goal is to make this package open-source, see help required below.
Status:

• Line charts are complete
• Pie charts are complete
• Bar and Bar with Line charts are working but require some minor changes
• Data can be given in categories and multiple lines and bars are drawn
• An area of the screen can be given for charting while application uses the rest of the screen
• With a sample application the obfuscated jar is 16 KBytes and takes 52 KBytes heap memory on the Nokia Series 60 emulator
• Axes drawing is partially working (lables and markers are missing)

TODOs:

• Customizations in drawing charts (Point circles, Axes stepping, lines in BarCharts, etc.).
• Chart titles, Axes titles, Data titles, Legend Charts for better explanation of charts.
• Finding a way to release the API in a way that source is hidden (till opensource efforts succeed).

Screen Shots:

Here you see a simple midlet on a Nokia 3650, with the charts occupying the whole j2me canvas area.
