JagPDF is a library for generating PDF documents in C/C++, Python, and Java. It supports TrueType (subsetting) and standard 14 Type 1 fonts, font metrics, Unicode, UTF-8 and common 8-bit character encodings, images (JPEG, PNG, or custom), paths, color spaces (RGB, CMYK, CIE based, ICC profiles, indexed), encryption, bookmarks, hyperlinks, and more.
j-XChange is a pure Java implementation of the entire Collaboration Data Objects (CDO 1.21) library for accessing Microsoft Exchange Server in a platform independent manner. This library will allow interoperability with MS Exchange from all non-Windows platforms that support Java. This library is powered by j-Interop.
xLightweb is an easy-to-use HTTP network library to build high performance, highly scalable network applications in Java. xLightweb provides a simple and intuitive API to write client side HTTP applications as well as server side HTTP applications. In contrast to the Servlet API, xLightweb is not only focused on server side programming. xLightweb also supports client side programming by providing high-capacity client side classes such as an HttpClient. It supports both blocking/synchronous programming as well as non-blocking/asynchronous programming.
libogg++java is a Java native interface to libogg++. It provides C++ and Java wrappers, as well as Java classes. It also provides control files to generate them from the libogg++ interface using SWIG. The major and minor versions of this JNI will track that of libogg++, but its bugfixes are independent of libogg++ bugfixes.
HeliDB is a database for storing key-value pairs from a Java program. The client program creates one database object per database file. The database objects can be configured to support different capabilities. In its simplest configuration, a database is a file-backed map. More advanced configurations can give it transaction support or fast record searches by indexing records in a B+ tree.
EntityFS is an object-oriented file system API for Java. It has a rich set of powerful file and directory manipulation tools that makes it much easier to work with file system entities from Java. The file and directory interfaces are implementation-independent, and there is support for building file systems on disk, in memory, or in Zip or Jar files. File systems can also be configured to support capabilities such as file data compression or metadata.
jSieve is a Java implementation of the Sieve mail filtering language defined by RFC 3028. Sieve is an extensible mail filtering language. Its limited expressiveness (no loops or variables and no tests with side effects) allows user created scripts to be run safely on email servers. Sieve is targeted at the final delivery phase (where an incoming email is transferred to a user's mailbox). jSieve is implemented as a language processor that can be plugged into any Internet mail application to add Sieve support.
