August 31, 2006 - OpenChronicle and Open Core Release 1.0rc1

OpenSubsystems has today released OpenChronicle 1.0rc1, a comprehensive tutorial to development of Java applications using Open Core middleware abstraction layer. The tutorial walks the developer through the design and implementation of a real world blogging application with basic functionality similar to websites such as Blogger, WordPress, LiveJournal and MySpace. It describes how to easily implement the application data model, code persistence working with any of the supported databases, make the application work as a POJO or EJB using any of the supported J2EE application servers and finally how to design flexible, skinnable web user interface with basic security features.

Open Core 1.0rc1 was released at the same date. This release improves the easy of use of this subsystem especially when used for implementation of application persistence layer. Some of the most common operations, such as creation, update, retrieval or deletion one or multiple data objects can be now fully coded just with 2 lines of code. This release also includes several important defect fixes to the build process provided by Open Core to applications using it.

June 30, 2006 - Open Core Release 1.0beta4

1.0beta4 is the final beta release of Open Core. This release concludes the development and testing phase of the first version of the middleware abstraction layer fully supporting at this time 9 database management systems, 4 J2EE application servers, 5 connection pools, 3 transaction managers and 2 deployment modes (J2EE and POJOs). This release was fully tested in all supported environments (POJO, JBoss, JOnAS, WebLogic and WebSphere) using the included automated test suite with over 150 JUnit tests. All aspects of Open Core are now fully configurable and the documentation was updated to include description of all the configuration options. In addition to usual set of bug fixes, Open Core now includes new simpler API to access the configuration information and new method to configure administration database access for J2EE application servers. We have also added documentation and demos for the integrated web user interface template engine and all the supplied templates.

May 21, 2006 - Open Core documentation update

We have published set of articles extensively documenting Open Core package. This new documentation includes description of features and a comprehensive walkthrough giving you a quick start with this library. To allow you to customize Open Core we have published guides how to add support for a new database, new J2EE application server, new connection pool and a new transaction manager in addition to those that are already supported by Open Core out of the box: DB2, HSQLDB, MaxDB, MS SQL Server, MySQL, PostgreSQL, Oracle, SAP DB, Sybase ASE, Commons-DBCP, C3P0, Proxool, XAPool, J2EE datasources, JOTM, J2EE transaction managers and custom in-JVM transaction manager, JBoss, JOnAS, WebLogic, WebSphere. In addition to already published walkthroughs how to setup each supported database we have published detailed instructions how to install and configure each supported application server and install Open Core on each of them. The instructions are for JBoss 4.03 SP1, JOnAS 4.6.6, Weblogic 9.1, WebSphere 6.

April 22, 2006 - Open Core Release 1.0beta3

1.0beta3 release of Open Core, a middleware abstraction layer providing foundation for rapid development and smooth integration of open subsystems was made available today. This release contains additional bug fixes, cleanup of build system resulting in simpler and fully reproducible distribution packages, support for automatic redirection between HTTPS and HTTP, support for modular web user interface and newly released framework for thick client applications independent from used GUI technology (with default implementation using SWT).

October 25, 2005 - Open Core Release 1.0beta2

Release 1.0beta2 of Open Core, a middleware abstraction layer providing foundation for rapid development and smooth integration of open subsystems brings many bug fixes and also fully tested functionality for all supported databases, connection pools and transaction managers (so far only in POJO environment). Included are two new tutorials: Database Setup and Implementing Support for a New Database.

September 8, 2005 - Open Core Release 1.0beta1
