What is EclipseLink EIS
The EIS persistence service enables the usage of data stores through Java Connector Architecture (JCA) resource adapters. Using XML metadata the interactions and their exchanged data are configured and mapped onto a domain model. The interactions data can be mapped from either the Common Client interface (CCI) or using XML schemas. This usage is intended for non-relational data stores where no JDBC or SQL access is provided.
See Developing EIS Projects in the EclipseLink User's Guide for more information.
