jbootstrap is a tool that bootstraps your Java application without complex CLASSPATH settings. As long as your JAR dependencies are under one directory, jbootstrap will pick up the JARs, create an appropriate classloader, and fire up your application without requiring CLASSPATH adjustments.
Architecture Rules is a Java library that allows a programmer to assert code's architecture via unit tests or ant tasks. This test is able to assert that specific packages do not depend on others and is able to check for and report on cyclic dependencies among your project's packages and classes. This project wraps a industry accepted JDepend to simplify the process of maintaining a solid software architecture.
J4ME is a library to help with J2ME development. It includes a UI framework for professional-looking and intuitive interfaces, a logging framework to help debugging platform-specific issues found on different phones, a Bluetooth GPS integrated into the JSR-179 Location API, and a library of missing J2ME methods and helpful collections for small devices.
VeriTAR [Veri(fy)TAR] is a command-line utility that verifies the MD5 sums of files within a tar archive. Due to the limitations of the tar ("ustar") format, the MD5 sums are retrieved from a separate file and are checked against the MD5 sums of the files within the tar archive. The process takes place without actually exctracting the files. It works even with corrupted tar archives. The program carries on to the next file within the archive, skipping the damaged parts. At the moment, this relies on internal functions of Python's tarfile module.
