Reality Java Interface Programming Guide

The Reality Java Interface Programming Guide is applicable to JReal V3.0 and V3.1 and the Reality SQL/JDBC Driver V1.0.

JReal V3.0/V3.1 comprises:

• DDA classes within the com.northgateis.comms.dda package. These classes allow a Java program to make a connection and access information in a Reality database by sending DDA messages across a TCP/IP network.
• RSC classes within the com.northgateis.reality.rsc package. These classes allow a Java program to access a Remote Basic subroutine (a DataBasic subroutine that has been enabled for use via remote access).
• Utility classes - including ItemView, which allows a Reality item to be broken down into attributes, values and subvalues.
• Servlet connection classes, which allow you to write custom servlets to access a Reality database via RealWeb.

The RealSQL-JDBC Driver V1.0 comprises

• RealSQL classes within the com.northgateis.reality.realsql package. The driver uses the JReal DDA package to make a connection and access data on a Reality database. The RealSQL classes allow the Java program to construct SQL commands to execute queries or update the database.

This help system provides guidelines, with examples, for a Java programmer wishing to enquire upon or update a Reality database using the RSC package, RealWeb, or the Reality SQL/JDBC Driver. For a summary of these methods, and the intended readership of this guide, please refer to the Overview.
