DashO is a Java application obfuscator, optimizer, and packager. It performs a dependency analysis on the application, removing unused methods and fields. Classes and members can be renamed using the patented Overload-induction renaming algorithm. Byte code optimization, control flow obfuscation, and string encryption can also be selectively applied. Special features include analytics for Java/Android/RIM/J2ME including exception reporting, Android obfuscation and tamper protection, and JAR watermarking.
db4o is an object database for Java and all .NET environments. Its features include ACID transactions, automatic class schema recognition, query-by-example, a S.O.D.A. object querying API, native queries, LINQ support on .NET, callback methods, memory files, cascade-on-delete, multi-threaded access, and Java Webstart and servlet support.
NetStereo is a server which runs on a computer with a sound card and plays music, primarily MP3s. What makes the NetStereo server special is that it accepts commands from remote clients. The server is written in Java, and it features the ability to plug in various methods of playing songs (currently mpg123 and the Java Media Framework) and various methods of communication (currently network and serial port).

Originally named Sync4j, the Funambol Mobile Application server includes a suite of tools to develop, deploy, and manage mobile projects. It includes push email functionality and is a certified implementation of SyncML (OMA DS/DM standard). It includes a mobile application server with connectors to SQL relational databases, Microsoft Exchange, Lotus Domino, and SugarCRM, applications for Outlook, Windows Mobile PocketPC, BlackBerry, Palm, and iPod for synchronizing address books and calendars, and a gateway for supporting mobile email. An SDK and an OMA DM server for remotely managing mobile devices are also included.
Apache Cayenne is a persistence framework that provides object-relational mapping (ORM) and remoting services. It has a wealth of unique and powerful features and can address a wide range of persistence needs. Cayenne seamlessly binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. With native XML serialization, objects can be even further persisted to non-Java clients.
