Open Source Software for Mobile Phones

J2MEMicroDB is an open source project developed in the Universitat Politècnica de Catalunya that provides J2ME developers with several APIs, to manage a relational database (a limited one) on a mobile device.

SerME is very simple serialization and persistence library. It is intended to be used at J2ME (MIDP 1.0 and MIDP 2.0) which is not providing reflection and serialization capabilities. SerMe is able to store data using two APIs: (1) - RMS (javax.miroedition.rms) is standard for J2ME an dincluded in MIDP 1.0, (2) - using files, which are supported by javax.miroedition.io.file package which is optional package for MIDP 2.0 implemented mostly on smartphones and PDA devices.

OpenBaseMovil is an framework for fast and seamless development of J2ME mobile applications.

If features:

• a powerful database engine, which can hold hundreds of thousands of data in multi megabyte databases.
• a scripting engine, so you can easily extend and create applications, and in the near future run them on any other mobile platform such as Android or Windows Mobile.
• a declarative view definition language, with a simple xml file you can generate all of your views, and they are script and data aware: you can browse a set of results with less than ten lines of code.
• and much more, like task control, files over RecordSets with random access capabilities, floating point support, internationalization, …
