Tool Installation
The pieces you will need
• Java Development Kit (JDK)
• Unisys BISRA (BIS Resource Adaptor)
• Eclipse or other IDE
![Page 4: Inbound Java](https://reader034.vdocument.in/reader034/viewer/2022051414/55a39a871a28ab69548b45d6/html5/thumbnails/4.jpg)
4
Installing Java Development Kit
http://java.sun.com/javase/downloads/index.jsp
Standard Edition or Enterprise Edition
• JDK (Java Development Kit) includes JRE (Java Runtime Environment) for Developers
• JRE (Java Runtime Environment) for the BIS server

Installing Unisys BISRA
From the BIS release CD

Installing Eclipse
http://www.eclipse.org/downloads/

Installing Eclipse
Eclipse does not use the Windows Registry

About Java
• Language Java ≠ Javascript (ECMA) Java is compiled; Javascript is interpretive Java on web server; Javascript in browser
![Page 10: Inbound Java](https://reader034.vdocument.in/reader034/viewer/2022051414/55a39a871a28ab69548b45d6/html5/thumbnails/10.jpg)
10
About Java
• Code Similarities to C, C#, C++ etc. prog.java (source) prog.class (byte code) JVM (Java Virtual Machine) executes prog.class Java is object oriented Java import like BIS :include Java try/catch like BIS error label Java char (Unicode) ≠ byte Everything (except primitives) is abstracted

Getting Rids w/o a Script
try { BISConnectionFactory bcf = BISResourceAdapter.createConnectionFactory(cp);BISConnection connection = bcf.getConnection();
BISDataset dataset = connection.getDataset("2b0"); BISClob clob = connection.getCLOB("2e0"); BISBlob blob = connection.getBLOB("31e0"); . . . dataset.close(); clob.close();blob.close();
connection.close();}catch (BISException e) {e.getStackTrace();}
Note: The connection object has methods to get hard-numbered, but not named rids.
