Jim (Java Image Manager) is a program for managing your personal images (photos, etc.). While Jim is really easy to use, its tagging technology is quite powerful. A plugin system makes it easy extensible with new technologies. It runs on several operating systems (including Windows, Linux and many more); all you need is a Java Runtime Environment.
Puggle is a desktop search engine that provides full text search over files, folders, music, photos, Web pages, and other data that are stored locally on your computer. Puggle is able to create many different indices, each with a different configuration. For example, you may have a different index for your music collection as well as your documents. Each of them can be used on demand, simply by loading it. Furthermore, Puggle supports indexing of portable devices, like USB flash drives or external hard disks. The index will be stored in the device, using relative paths, allowing you to search over the data very quickly on any computer.
Midao JDBC simplifies development with Java JDBC. It is flexible, customizable, and simple/intuitive to use, and provides a lot of functionality: transactions, working with metadata, type handling, profiling, input/output processing/converting, pooled datasource libraries support, cached/lazy query execution, named parameters, multiple vendor support out of the box, custom exception handling, and overrides. With a single jar, it supports both JDBC 3.0 (Java 5) and JDBC 4.0 (Java 6). Midao JDBC is well tested. Not only does it have around 700 unit and functional tests, but it's also tested with the latest drivers of Derby, MySQL (MariaDB), PostgreSQL, Microsoft SQL, and Oracle. Midao is a data-centric project. Its goal is to shield Java developer from nuances of vendor implementation and standard boilerplate code. Midao JDBC is the first library released under it.
