Projects / OpenSubsystems


OpenSubsystems is set of business components for Java applications such as security, search, inventory management, order processing, shopping, email and fax communication, document management, imaging, and others. The components can be used directly on top of Java Virtual Machine (POJO) or using various J2EE application servers (EJB). This is all without changing a single line of code.

    Release Notes: The main focus of this release is to simplify steps required to adopt the list data pattern. List data pattern allows accessing large amounts of data in a relational database in small chunks. It allows the retrieving of data page by page, or direct accessing of a specified page. A page represents several data items retrieved and displayed together. The page size is user- and system-configurable. The list data pattern portion of the Quick Start guide was greatly enhanced to navigate users through implementation of this pattern.
