Product Overview

Web Enabler for ClearPath MCP is a Java-based, cross-platform client/server application. It enables users of ClearPath MCP servers to access MCP server applications over the Internet or an intranet using a Java- capable Web browser.

Web Enabler for ClearPath MCP is ideal for quickly and easily Web-enabling MCP applications for the Internet.

You can also install Web Enabler as a stand-alone client application. In this environment, a Web browser is not required for normal operation. When running as an application, Web Enabler for ClearPath MCP offers most of the features (with the exception of Web page scripting) provided in the browser-based version. In addition, certain security restrictions are relaxed and additional features are enabled by default.

General Features

Customization

Web Enabler for ClearPath MCP supplies over 300 functions and events to scripting languages such as JavaScript and Visual Basic Script. Combined with the power of HTML, Dynamic HTML, and XML, it provides tremendous flexibility and power to enhance the functionality and user interface of your applications. Signed applets are supported for Macintosh users.

Graphical User Interface

Web Enabler for ClearPath MCP includes easy-to-use, context-sensitive menus that enable you to modify the look-and-feel of current and future sessions on the fly. Web Enabler provides a consistent look-and-feel across platforms. You can choose a look-and-feel reminiscent of a traditional T27 terminal or one that resembles a modern Web page.

Global Access

Web Enabler for ClearPath MCP provides global Web access to MCP server applications. If Internet access is available, users have virtually immediate access to MCP applications from anywhere in the world.

If necessary, HTTP Tunneling software can be installed and configured inside a private network. This software allows a Web Enabler applet or application to bridge a firewall and access an MCP server within the private network.

Internationalization

Web Enabler includes support for the Japanese and Chinese languages as well additional support for European languages.

A graphical user interface (GUI) tab is provided specifically for customizing language features. In addition, a Java based encoder interface is available for users that require special fonts with nonstandard character mappings; this interface provides a way of converting user-encoded byte arrays to and from Unicode strings. The encoder can also be used to determine if a Unicode character is to be represented as a double-wide character.

The Web Enabler for ClearPath MCP user interface can also be localized by modifying the Java resource files, HTML text, and bitmap graphics.

Web Enabler for ClearPath MCP supports user-defined encodings and can be configured to display Asian characters. Additional T27K functions are available in Japan.

Performance and Scalability

Unlike many alternative methods for Internet-enabling MCP applications, Web Enabler for ClearPath MCP requires no changes to existing applications and requires no intermediate gateways or manual conversion of terminal-based forms and screens. Using a "two-tier" approach (that is, the MCP server and your workstation-based Web browser), Web Enabler maintains transaction performance and scalability similar to your existing terminal network.

Platform Independence

Web Enabler for ClearPath MCP provides cross-platform support with a single version of the application.

Reduced Installation, Maintenance, and Upgrade Costs

Web Enabler for ClearPath MCP can be delivered over the network to the client on an as-needed basis. Client software does not need to be manually installed or updated by users to access applications on an MCP server.

Web Enabler Wizard

The Web Enabler Wizard is an applet that provides users with a convenient way to create HTML pages and publish them to a Web server. Once published, these pages can be accessed by anyone with access to the URL.

Pages created with the Web Enabler Wizard can include JavaScript to provide custom behavior for your applet.

New Features/Enhancements

Web Enabler now provides an HTTP Tunneling component, which enables Web Enabler to pass through firewalls using a proxy server over an internet connection. The HTTP Tunneling component enables you to use more flexible security configurations. Web Enabler validates the certificate that is presented by the HTTP Tunnel server when establishing a secure connection to the HTTP Tunnel server. If the certificate cannot be validated, Web Enabler notifies the user of the certificate exception and prompts the user to either terminate or continue the connection.

Configuration Requirements
