The Java Connection JSP and Apache Tomcat

Introduction

The Java/JSP Connection provides a suite of sample programs describing various coding or programming techniques using the Java Software Development Kit from Oracle/Sun. The Web Server used in this suite of programs is Apache/Tomcat.

We have made a significant effort to ensure the documents and software technologies are correct and accurate. We reserve the right to make changes without notice at any time. The function delivered in this version is based upon the enhancement requests from a specific group of users. The intent is to provide changes as the need arises and in a timeframe that is dependent upon the availability of resources.

Java and COBOL

This section contains information about COBOL and Java working together as complementary technologies.

Java, COBOL and Micro Focus

A fifteen (15) day "Discovery-Session and Proof-of-Concept" project was completed by SimoTime Enterprises during December, 2001. The objective of this project was to determine the practicality of using existing COBOL programs or parts of programs to backend an Internet frontend written in Java. This project used the Java Developer's Kit (JDK) from Sun Micro systems, Micro Focus Net Express for the COBOL and a Lite Web Server from Gefion Software.

Utility Programs

This section contains the links to information about SimoTime Utility Programs that execute in a Java Environment.

Hex Dump with EBC and ASC

This java utility program will describe and demonstrate techniques for accessing oreviewing files of known and unknown structure and content are included. The viewing (or human observation) is provided in a hexadecimal (or hex) dump format with a possible EBCDIC or ASCII translation.

Review the Documentation for this suite of program members.

MC T112 File Conversion

The SIMOTIME T112 Conversion Utility Program will convert the EBCDIC-encoded, T112 file to an ASCII/Text file with the bit-sensitive information expanded to text strings. The Master Card or MC T112 file is a clearing file for financial transactions. The record structure uses an Integrated Product Messages (IPM) format with variable-length records. It is based on the ISO 8583-1993 specification.

Summary

The purpose of this document is to assist as a tutorial for new programmers or as a quick reference for experienced programmers that are interested in the Java programming environment. Links to additional documents, programming examples and professional services are provided.

In the world of programming there are many ways to solve a problem. This documentation and software were developed and tested on systems that are configured for a SIMOTIME environment based on the hardware, operating systems, user requirements and security requirements. Therefore, adjustments may be needed to execute the jobs and programs when transferred to a system of a different architecture or configuration.

Company Overview

SimoTime Technologies was founded in 1987 and is a privately owned company. We specialize in the creation and deployment of business applications using new or existing technologies and services. We have a team of individuals that understand the broad range of technologies being used in today's environments. Our customers include small businesses using Internet technologies to corporations using very large mainframe systems.

Quite often, to reach larger markets or provide a higher level of service to existing customers it requires the newer Internet technologies to work in a complementary manner with existing corporate mainframe systems. We specialize in preparing applications and the associated data that are currently residing on a single platform to be distributed across a variety of platforms.

Preparing the application programs will require the transfer of source members that will be compiled and deployed on the target platform. The data will need to be transferred between the systems and may need to be converted and validated at various stages within the process. SimoTime has the technology, services and experience to assist in the application and data management tasks involved with doing business in a multi-system environment.

Whether you want to use the Internet to expand into new market segments or as a delivery vehicle for existing business functions simply give us a call or check the web site at http://www.simotime.com
