UNIKIX OFFERS JAVABEANS TO ACCESS LEGACY DATA.Unikix Technologies has developed a set of JavaBeans for accessing legacy mainframe data. Unikix is perhaps best known for its clone of IBM's CICS (Customer Information Control System) A TP monitor from IBM that was originally developed to provide transaction processing for IBM mainframes. It controls the interaction between applications and users and lets programmers develop screen displays without transaction monitoring software for Unix systems, and has over the past few years been repositioning itself as a middleware vendor to help mainframe shops extend their legacy systems rather than replace them, although the company does still sell its eponymous transaction monitor and development tools. Unikix is owned by the Fisher Technology Group, which operates an online mall for Fisher Scientific, the $2.1bn provider of lab equipment. Unikix has obviously come to the conclusion, that IBM's mainframes are going to be around for a while longer at least, and is going to try to make money selling Java applets that will be undoubtedly be necessary to make mainframes useful in an e-business world. To that end, Unikix has developed two JavaBeans and a framework for using them. The 3270 Screen Bean provides direct access for Java applications to 3270 mainframe applications written in CICS, TSO (Time Sharing Option) Software that provides interactive communications for IBM's MVS operating system. It allows a user or programmer to launch an application from a terminal and interactively work with it. The TSO counterpart in VM is called CMS. or the IMS (1) See IP Multimedia Subsystem.

Developers writing Java applications would code the web side of their applications and then use the Screen Bean to access the mainframe. The Screen Bean provides field level access to all fields in the 3270 data stream embedded in legacy applications. Unikix says that the Screen Bean is written entirely in Java and can be embedded in any Java integrated development environment See IDE.
integrated development environment - interactive development environment , including IBM's Visual Age for Java, Inprise's JBuilder and Symantec's Cafe. Multiple instances of the Screen Bean can be used in the same application. The Pathfinder Bean Developer is a tool for sniffing through the 3270 data stream in legacy applications to find application fields for the Screen Bean to use. Pathfinder generates JavaBeans that describe a particular navigation path through an application, which can then be re-used by other portions of a Java meta application. Both the 3270 Screen Bean and Pathfinder Bean Developer are available immediately. They will run on any client or server with a Java virtual machine A Java interpreter. The Java Virtual Machine (JVM) is software that converts the Java intermediate language (bytecode) into machine language and executes it. The original JVM came from the JavaSoft division of Sun. . Screen Bean costs $50 per client or $10,000 for an unlimited server license. Pathfinder costs $1,500 per developer. Aidan Harney, president of Unikix, says that Screen Bean and Pathfinder will be particularly popular at mainframe sites because it does not require customer to tweak their mainframes to use it.

Screen Bean and Pathfinder provide easy access to this huge installed base from any Java IDE." The Extended Call Interface is an extension of the CICS transaction monitor program that w as originally designed to act as a glue for cementing CICS applications to Windows clients via Microsoft's Object Linking and Embedding See OLE.

DCOM is based on COM, Microsoft's component software architecture, which defines the object interfaces. . Rather than work through the ECI framework (which bypasses CICS application screens and links a Windows application written, say, in Visual Basic, directly to the CICS transaction monitor), Screen Bean and Pathfinder actually use the existing 3270 data stream, much as CST's Jacada Innovator for AS/400s - also a Java application - does for the 5250 data stream in AS/400 RPG (Report Program Generator) One of the first program generators designed for business reports, introduced in 1964 by IBM.

Both Screen Bean and Pathfinder are part of a larger Unikix initiative called the Component and Legacy Application Servers (CLASS) framework. The CLASS framework involves four different ways of extending legacy applications to the Web. First, use object wrappers like Unikix's KixORB Corba object server to encapsulate en·cap·su·late

Third, use Screen Bean and Pathfinder and other forthcoming Java components to extend legacy applications without having to change the code underlying the legacy application. And fourth, integrating native CICS and Java applications on the mainframe. Unikix says that the CLASS framework will allow companies to move from a CICS/Cobol structure on their mainframes to a Java/CICS/Enterprise JavaBean architecture.
