Packaging and Deployment in the Borland Enterprise Server and VisiConnect
A Resource Adapter packages a set of Java interfaces and classes, which implement
the Connectors-specified system contracts and EIS-specific functionality to be
provided by the Resource Adapter. The Resource Adapter can also require the use of
native libraries specific to the underlying EIS, and other collateral, for example:
■
■
■
■
■
Documentation
Help files
A code generator for EJBs
A tool that directly provides configuration utilities so you can configure the EIS
directly
A tool that provides additional deployment facilities for remote Resource Adapter
components
■
For example, with IBM CICS, a set of JCL scripts that you may need to run on the
mainframe
The Java interfaces and classes are packaged together, with required collateral and
deployment descriptors, to create a Resource Adapter module. The deployment
descriptors define the deployment contract between a Resource Adapter and the
application server
A Resource Adapter can be deployed as a shared, standalone module, or packaged as
part of a J2EE application. During deployment, the Resource Adapter module is
installed on the Borland Enterprise Server and configured for the target operational
environment. The configuration of a Resource Adapter is based on the properties
defined in the deployment descriptors.
