h3270 is a program that allows you to use IBM 3270 hosts from within a web browser.




h3270 is a program that allows you to use IBM 3270 hosts from within a web browser.
h3270 is different from other, similar systems because of its highly configurable layout engine that is based on regular expressions.

Classical mainframe applications are still part of the IT infrastructure of most large enterprises. The challenge is often to integrate them with more recent, browser-based systems. h3270 allows you to do that in two steps:

- It renders 3270 host screens in HTML and makes them operable from within a web browser. This process works out of the box in a simple, character-based layout that resembles the original terminal screen. Optionally, the layout can be enhanced using a configurable engine so that it looks and feels like a real web application.
- The HTML adapter is available both as a servlet and a portlet, so that it can be used either as a stand-alone web application, or inside a portal server, which allows for seamless integration with other applications at the user interface level.

h3270 is a server-side Java application that is compliant with the J2EE standard and the Portlet API (JSR-168). To access the 3270 data stream, it uses the s3270 program written by Paul Mattes, which in turn relies on the TN3270 format to access the host via Telnet (TCP/IP).

What's New in This Release:

h3270 version 1.3.3 improves the keyboard handling again. The change in the previous release, where we attached keyboard handlers to individual input fields, has shown not to be sufficient for many people. You could no longer input anything on screens with no input fields.
In version 1.3.3, keyboard handlers are again global, on a per-page basis. To support multiple sessions within the same browser (or on the same portal page), keyboard handlers are now installed dynamically. When the mouse moves into a terminal window, a global, page-scoped keyboard handler is installed for that window. You can also force installation of a keyboard handler by clicking somewhere within the terminal window.
We hope this method proves practical for everybody, please let us know if not. Another change in this release is improved error reporting in case of unknown (mis-spelled) or unreachable hosts.
