Google Authenticator Demo is an implementation of two-factor authentication using the Google Authenticator that can be used on your own site or application. It allows you to register a user name and then log in using the information provided by the Google Authenticator. It also works with OATH HOTP compliant hardware tokens.
persistence4j is a small and lightweight Java object persister that uses JDBC to persist data into a relational database. The library frees you from writing the Data transfer objects - just create a POJO and simply save it. Transactional and non-transactional connections are supported and can be configured from the simple properties file.
MASH is a modular, automated script harness. It allows users to implement simple harnesses that perform work external to a system. The framework will invoke that harness as outlined by an XML script. For example, when using the framework to test a system you could create a script that cleans and loads a database, FTPs some data, submits a login form, and verifies HTTP information. Harnesses can easily be built to do almost anything (many harnesses are provided), not just Web page verification. While harnesses are written in Java, the scripts may be run against any type of system as harnesses are intended to act as clients.
