• JMemcached - A distributed cache; a Java implementation of the daemon (server) side of the memcached protocol. It implements a clone of the C version of the memcached daemon, but in pure Java. It is protocol compatible with the C version of memcached. Existing clients, including the one for Java, should work without modification. Replacing the Java version with the C version (and vice versa) is trivial. It can be embedded in your existing Java project, or used from its command-line interface (which mimics the C version in arguments).


• JRel - a library for Java language which can be used to construct database queries in a programmatic fashion using a subset of the relational algebra. These queries are expressions in the form of 100% native Java code, and are translated at runtime into conformant ANSI-SQL usable with a variety of SQL databases.
