H3270 is a browser-based software that enables users to access IBM 3270 hosts directly from their web browser.
However, with h3270, this process is a walk in the park, accomplished in two straightforward steps. The software program first renders 3270 host screens in HTML, making them fully operable from a web browser. This process works out of the box in a simple, character-based layout that is similar to the original terminal screen. Alternatively, users can opt to have the layout enhanced to resemble a real web application using a highly configurable engine.
Furthermore, the HTML adapter is available both as a servlet and a portlet, making it a versatile tool that can be used either as a stand-alone web application or within a portal server. Notably, it ensures seamless integration with other applications at the user interface level.
h3270 is a server-side Java application that complies with the J2EE standard and the Portlet API (JSR-168). To access the 3270 data stream, the program uses the s3270 program written by Paul Mattes, which relies on the TN3270 format to access the host via Telnet (TCP/IP).
The latest version, h3270 version 1.3.3, comes with a few improvements. For instance, the program now boasts improved keyboard handling, with global keyboard handlers on a per-page basis. The software also supports multiple sessions within the same browser or portal page, with keyboard handlers installed dynamically. Users can force the installation of a keyboard handler by clicking inside the terminal window. The release also features improved error reporting in cases of unknown or unreachable hosts.
In summary, h3270 is a robust and highly configurable software program that offers a seamless way of accessing IBM 3270 hosts from web browsers. It promises to make a significant impact on large enterprises that rely on classical mainframe applications by bridging the gap between modern browser-based systems and older IT infrastructure.
