Integrating multiple legacy systems with the web

Legacy Objects Framework (LOF) Enterprise 3.1 is a set of development and deployment software tools for integrating and extending legacy systems. The tool set includes LOFModeler for development, LOF Server for deployment, and Cables.Web for secure web-based terminal emulation.

LOF Enterprise 3.1 Supports a Large Number of Legacy Systems

Manufacturer	Environment	Terminal	Comm. Protocol
IBM	zSeries(Mainframe) iSeries/AS400 (Midrange)	3270 5250	TN3270 TN5250
Unisys	1100/2200 Series System 80 ClearPath HMP IX	UTS	UNISCOPE INT1 DCP UNISCOPE INT1 HLC
Tandem	NonStop	6530	TN6530
DEC and many others	UNIX, VMS and other proprietary systems	VT-320/220/102/101/100/52 Wyse 60/50+ DG D215	Telnet & serial ports

Developing with LOF Enterprise 3.1

The LOFModeler captures and stores the important functions of the legacy system in an LOF Model and exports these functions to front-end applications as a legacy Application Programming Interface (API).

LOF Development Features

Powerful scripting language allows the creation of clean model API’s
Elegant GUI tools for creating the models
Merge data from:
- Multiple mainframe applications into a single user interface
- Different legacy hosts through different terminal emulations and operating systems
- Legacy applications with data from other sources

Client Environments

Supported Development Platforms

All Java, J2EE environments
Microsoftâ .NET applications:
ASPX, C#, Visual Basic, C++
Web Services (SOAP/WSDL) & XML applications

Microsoftâ Windows Win32 family:
Windows 2000 Professional

Windows XP Professional

Cables.Web: Secure, Web-based Terminal Emulation

Cables.Web allows a unique approach of incremental development and deployment. The Cables.Web integrated terminal emulator shares the same connection to the legacy system as the front-end application. The Cables.Web session provides complete access to any part of the legacy system that is not yet available to the front-end application. This allows you to create a partial LOF Model of the most important legacy system functions and deploy quickly.

Cables.Web features:

Self-installing thin client. Supports IE 6.0 and Netscape
Integrated with model-based screen-scraper (LOF) and shares a single session to the host
Strong encryption between the browser and Cables.Web server
Very small Java applet size
Configurable color mapping, keyboard mapping, button panels, title and fonts
Automatic font scaling
Scaleable architecture: multiple servers and processes; automatic rollover; no single point of failure

Security

LOF Enterprise 3.1 supports a large number of encryption standards for communication between the front-end applications, their associated Cables.Web sessions and the LOF Servers.

Security Options
RSA (Public Key/Private Key) 1024- and 2048-bit DES 56-bit Triple DES (3DES) 112-bit	Blowfish 128-, 192- and 256-bit AES (Advanced Encryption Standard) 128-, 192- and 256-bit CAST 128-bit

Deploying LOF Enterprise 3.1

Web Portals and Front Ends built with LOF Enterprise 3.1 are deployed in a multi-tier architecture where the LOF Servers form the tier between the legacy system and the web application. These LOF Servers run in a peer-to-peer network administered by the LOF Directory Server, one of the many server application tools included in LOF Enterprise 3.1.

LOF Deployment Features

Robust error handling
Scaleable architecture:multiple servers and processes; automatic rollover, no single point of failure
Strong encryption between the application server and the LOF server
Centralized administration of LOF Servers
