XmlBlaster is XML based MOM (Message oriented Middleware) with a lot of features. It is a publish/subscribe and point-to-point MOM server which exchanges XML-encoded messages. Communication with the server is based on CORBA (using JacORB), RMI, XML-RPC, native socket, or a persistent HTTP plugin. Subscribers can use XPath expressions to filter the messages they wish to receive and add their own MIME-based filter plugins. C/C++, Java, Perl, Python, VisualBasic.net, C#, and PHP client demos are included in the xmlBlaster test suite, and Tcl and Python demo clients are scheduled. XmlBlaster also provides a browser callback framework, allowing browsers (Netscape, Mozilla, MSIE) to receive instant callbacks over a persistent http connection. A security plugin framework allows authentication/authorization in many ways. Currently there are LDAP- and passwd-based plugins available.
TAO is a standards-compliant, real-time implementation of CORBA that provides efficient, predictable, and scalable quality of service (QoS) end-to-end. Unlike conventional implementations of CORBA, which are inefficient, unpredictable, non-scalable, and often non-portable, TAO applies the best software practices and patterns to automate the delivery of high-performance and real-time QoS to distributed applications.
omniORB is an Object Request Broker (ORB) which implements version 2.6 of the Common Object Request Broker Architecture (CORBA). It supports the C++ and Python language bindings, is fully multithreaded, uses IIOP as the native transport, and comes complete with a COS Naming Service. omniORB is one of the fastest available C++ ORBs.
PyORBit is a Python binding for the ORBit2 CORBA ORB. It was developped to suit the needs of the bonobo bindings in GNOME-Python, but is usable for other purposes as well. It aims to follow the standard Python language mapping for CORBA. It can generate stubs at runtime from typelibs, IDL files, or by introspecting remote objects using ORBit2's IModule typelib capabilities.
OpenEJB is a simple, lightweight Enterprise JavaBeans (EJB) container and server. You can embed OpenEJB in your own applications, or in a Web application server like Tomcat, or run it as a standalone EJB server. It supports EJB 3.0, 2.1, 2.0, and 1.1, and has partial support for EJB 3.1.
SDE for NetBeans is a UML modeling environment tightly integrated with NetBeans. It lets you draw all types of UML diagrams (use case diagram, class diagram, sequence diagram, activity diagram, etc.) in NetBeans, reverse source code (Java, C++, XML, XML Schema, CORBA IDL, etc.) to UML models, and generate Java source from UML diagrams. It features a Rational Rose importer, an XMI importer, HTML/PDF documentation generators, and plug-in and template support.
ACDK is a development framework with a similar target of Microsoft's .NET or Sun's ONE platform, but it uses C++ as a core implementation language. It implements the standard library packages, including acdk::lang, acdk::lang::reflect, acdk::util, acdk::io, acdk::text (including regexpr), acdk::net, acdk::sql, acdk::xml, and more. Flexible allocator/garbage collection, threading, and Unicode are implemented in the core of ACDK. Extensions make C++ objects available for reflection, serialization, aspect-oriented class attributes, and [D]ynamic [M] ethod [I]nvocation. This DMI acts as an universal object oriented call interface to connect C++ with scripting languages (Java, Perl, Tcl, Python, Lisp, Visual Basic, and VBScript) and standard component technologies (CORBA and COM).
