HornetQ is a multi-protocol, embeddable, high performance, clustered, asynchronous messaging system. HornetQ is an example of Message Oriented Middleware. It includes an extensive, easy-to-understand user-manual and quick-start guide and over 65 ready-to-run examples out of the box, demonstrating everything from simple JMS usage to complex clusters of servers and more exotic functionality. Its elegant POJO based design has minimal third party dependencies. You can run HornetQ as a stand-alone messaging broker, run it in integrated in your favorite JEE application server, or run it embedded inside your own application. Its journal provides high persistent messaging performance. Automatically switching into native mode when running on Linux, it uses asynchronous IO to provide persistent messaging rates that can saturate the write throughput of a disk. Its pluggable transport system uses JBoss Netty out of the box to provide high performance and scalability on the wire.
IPv6 CARE, "IPv6 Compliant Automatic Runtime Environment", provides an environment where applications instantly become IPv6-compliant ('patch' mode, see RFC6535). It can also generate a diagnosis about the IPv6 compliance of an application ('check' mode). It uses an LD_PRELOAD-based library injection technique.
Icwri is a lightweight, very simple, service-oriented Java built-in script. It can help Java developers build some application interfaces in a service-oriented style. It can also help non-technical people join the development team to write their own application scripts to enforce business rules and decisions. Icwri service providers and consumers can be either Icwri scripts or Java classes. An Icwri script can run all alone, but the primary purpose of Icwri script is to have an assistant language of Java. It can run on any system with JDK/JRE 1.5 or above installed. It does not support Java SE 6 Script Engine because of the service-oriented design and the requirement to support Java SE 1.5 users.
JCR Shell is a shell interface to manage JCR repositories like Apache Jackrabbit, Hippo CMS 7, and other JCR 1.0 (JSR 170) capable repositories. It uses RMI to communicate with the server. It features tab completion on names, types, and properties, the ability to import and export XML, a JCR diff tool, queries, reference lookups, and namespace management.
Jacman is a GUI frontend to ArchLinux's "pacman" package management system. It provides an attractive interface to the majority of key features of Pacman, including installing, removing, and updating packages. It also includes "rollback" functionality to return back to an older version if necessary.
JasperStarter is a commandline launcher and batch compiler for JasperReports. It can run any JasperReport that needs a JDBC data source or empty data source, use any database for which a JDBC driver is available, execute reports that need runtime parameters, print directly to the system default or a given printer, optionally show a printer dialog to choose a printer, optionally show a print preview, export to file in the PDF, RTF, .docx, .odt, and HTML formats, export multiple formats in one commanding call, print and export in one commanding call, and integrate in non-Java applications (for example PHP, Python) A binary executable is available for Windows. The string, int, and date parameter types are supported.
