Cling is a complete, clean, and very flexible Java implementation of the UPnP Device Architecture specification. Additional UPnP service modules and graphical tools are also part of this project. Cling helps you create, control, and monitor UPnP-compatible services on your local network. Cling can be used as an UPnP/DLNA library for Android application development.
UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use Java API for communicating with LDAP directory servers and performing related tasks like reading and writing LDIF, encoding and decoding data using base64 and ASN.1 BER, and performing secure communication. It may be used on any platform that supports Java SE 5.0 or later, as well as on Android mobile devices.
Frink is a calculating tool and programming language designed to help you in the real world. It tracks units of measurement throughout all calculations and ensures that answers are correct. It converts between systems of measurement, and has a huge library of physical data. It is both a simple calculator for quick calculations and a full-fledged programming language for large tasks. It draws high-quality graphics, handles conversions between time zones, currencies, and historical values of the U.S. dollar and the British pound, translates between several languages, does date/time math, and more.
ProGuard is a shrinker, optimizer, obfuscator, and preverifier for Java bytecode. It detects and removes unused classes, fields, methods, and attributes. It optimizes methods and removes dead code. It renames the remaining classes, fields, and methods using short, meaningless names. Finally, it preverifies the processed code for Java 6 or higher, or for Java Micro Edition. The resulting code is more compact, more efficient, and more difficult to reverse-engineer. Advantages of ProGuard compared to other Java shrinkers and obfuscators are compact template-based configuration, memory efficiency, and speed. It is mostly popular for embedded development and for commercial development, and is integrated in Oracle's Wireless Toolkit, in Intel's TXE SDK, and in Google's Android SDK.
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.
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.
