The SNA JCA LU0 Connector enables a Java(TM) application to send requests and get responses from a legacy Enterprise Information System (EIS). The SNA JCA LU0 Connector enables you to deploy these applications into a managed environment in which a J2EE-capable application server such as WebSphere(R) Application Server handles connection pooling, transactions, and security. To support this, the SNA JCA LU0 Connector implements the J2EE Connector Architecture (JCA).
This document provides a brief overview of the SNA LU0 protocol and the various supported data flow protocols. It also provides an overview of the JCA and how applications can use it to access SNA LU0.
