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.
SPOPS (Simple Perl Object Persistence w/ Security) is a robust and powerful Perl module that allows you to serialize objects. It is unique in that it also allows you to apply security to these objects using a fairly simple but powerful scheme of users and groups. It's also unique in that for most objects, you will not need to write any code. All you need is a fairly simple configuration file, and you can have a class for your object ready to go, right out of thin air.
XParam is an extensible, type-safe, non-intrusive, object-oriented tool for general-purpose object serialization and deserialization in C++, good for parsing command-line parameters and cross-program/cross-platform communication. It can handle named parameters as well as object streams. It recognizes class hierarchies, abstract interfaces, and polymorphism, and can therefore serve as a plug-in management framework (e.g., for strategy management).
The Jabber Object Access Protocol (JOAP) allows object attributes and methods to be accessed over the Jabber network. joap-perl implements JOAP in Perl. It lets developers define their own JOAP servers and classes in Perl, and it also lets them use remote servers and classes in a transparent and Perlish way.
MQS (Minimalist Queue Services) is a minimalist queueing system that provides a set of basic methods in order to offer asynchronous messaging for program/application. Applications can use this type of services in order to store and retrieve messages to a dedicated queue in the queue services. This allows you to avoid direct connection between applications and provides a simple asynchronous communication system. It provides a simple set of XML-RPC methods for pushing and getting messages in a specific queue (so you can use the system with any application that can talk XML-RPC). The queues are stored in a database (e.g., MySQL) or in dedicated db files (e.g. QDBM).
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).
Wiaflos Accounting is an attempt to create a multi-platform server-client based accounting system. The goal is to have a central accounting engine which can either run on a dedicated server or on the same PC as the client interface. A SOAP API allows for the easy writing of GUI or Web interfaces or for tying into in-house systems. It is intended to be useful for everyone from single-person organizations to multinational corporate entities.
