Open message queue is an enterprise quality, production ready, scalable messaging server. It provides a complete Java Message Service (JMS) implementation for message oriented system integration.

Open MQ 4.4 will be focused on, and coordinated with the planned release of GlassFish v3. GlassFish v3 will implement Java EE 6 and work on Open MQ will first address changes and requirements for JMS Providers in Java EE 3 and, secondly, features that we have received customer feedback about.

An object persistence framework is essentially a library of pre-written code that takes care of the details of persisting, or permanently storing an object. There are already some OPFs available for the Delphi Win32 versions, for example the open source tiOPF which has an active community.

Another project has now joined this group, hcOPF, developed by Larry Hengen.

Read more about hcOPF on  http://www.tpersistent.com/

The project is hosted on SourceForge at http://sourceforge.net/projects/larryhengensopf/.
