GemStone/J Overview

An integrated Java Application ServerDesigned for 3 tier transactional Java applications

built with componentsJava VM and runtime with significant value added Implicit Java object persistence

For application control and meta-data For shared data caches For extending relational and mainframe data

Integrates middleware and component technologies such as J2EE, EJB and CORBA

Supports development and deployment of large, complex business applications in Java
