Web390: Secure S/390 Meets the Web
Web390 is the HTTP/HTTPS server that transforms an IBM S/390 into a World Wide Web application and data server capable of supporting global Internet and Intranet activities of new and existing S/390 users. S/390 offers an ideal Web server environment, designed from the ground up to provide secure, 24-hour simultaneous access to applications and vast stores of data. Web390 links the S/390's massive processing power and storage capacities with the popular Web browser, providing a convenient way for organizations to communicate and distribute services and information to audiences worldwide.
Web390 provides a secure gateway to existing 3270-based applications running under MVS/TSO, CICS or VM/CMS, giving Web browser users immediate access to the legacy applications and data that support day-to-day commercial operations. Users have a choice of screen presentation modes, to customize the look and feel of the application to their specific tastes. Users can also be given protected access to all datasets allocated in the S/390 environment and application developers can write CGI (Common Gateway Interface) programs in traditional S/390 languages to accept and process input from Web browsers. With Web390, you can reuse your existing data access code, written in COBOL, PL1, or Assembler, to publish operational data directly on the web.
Since Web390 is a secure https server, mainframes can serve as repositories for distributing information to an entire workforce or customer base, on a “need to know” basis, in a completely secure fashion. The Web390 server supports all of the popular Web file formats (mime types), including HTML, VRML, GIF, and JPEG graphic files, as well as MPEG animation files and, of course, JavaScriptTM and JavaTM applets. With Web390, all of your Web-based content is hosted in a native S/390 environment: standard minidisk files or SFS directories on VM, and standard PDS, PDSE and flat files in the MVS environment. There is no need to implement UNIX services in order to host your web sites and grant web access to applications with Web390.
Web390's robust OpenCGI supports the use of Common Gateway Interface (CGI) scripts written in REXX, server-side JavaScriptsTM, or in 3GL languages such as C++, Assembler, PL1, and COBOL for accessing native S/390 data. Plus it supports more advanced -- Web-based data publishing tools like Information Builders' WebFOCUS product for building robust self-service applications and managed reporting environments which access operational data. Its broad language support facilitates rapid enhancement and exploitation of mainframe production systems on the Web.
