HP ChaiServer and Chai Developer Kit Foster Intelligent Appliances and Their Communication Via the Web

SAN JOSE, Calif.–(BUSINESS WIRE)–Nov. 2, 1998–

HP Announces HP ChaiVM Version 2.0, Innovative, Web-based

Access and Service for Embedded Systems

Hewlett-Packard Company today announced, under the umbrella of its new Chai product-family name,(1) the availability of ChaiServer and Chai Developer Kit for embedded-systems developers. Using these products, developers will be able to exploit World Wide Web protocols to build applications that create user-to-appliance and appliance-to-appliance interaction via the Web.

HP ChaiServer is written completely in the Java(TM) programming language and is deployable in any environment that supports HP ChaiVM or other virtual-machine implementations that comply with the Java virtual-machine specification.

The announcement was made here at the Embedded Systems Conference, which runs through Nov. 5.

ChaiServer uses the World Wide Web’s URLs (Uniform Resource Locators) to identify and directly access individual devices and their applications. This makes it possible to access a device and its services via any browser, or to call these services programmatically. Further leveraging Web protocols, all communication is done over HTTP (HyperText Transport Protocol). With ChaiServer, there is no need for techniques such as Common Gateway Interface (CGI-Bin).

The ChaiServer product suite also includes a set of Chailets for the following:

— application loading and unloading; — event notification; and — security management.

These Chailets can be used as separate applications or can be used within the Chailets developed by others. The ChaiServer model also allows for simple integration with applications supporting common object component models such as COM and CORBA.

ISVs and device manufacturers can create their own value-added Chailets. The Chai Developer Kit facilitates Chailet development.

Available free over the Web to developers today through Feb. 2, 1999 are the following:

— ChaiServer invocation specification — for developers who want to

build their own URL/HTTP-based Web server for appliances; — evaluation versions of the ChaiServer and Chai Developer Kit; and — sample Chailets.

“HP’s embedded-software initiatives are bringing exciting new dimensions to the world of intelligent appliances,” said Jim Bell, general manager of HP’s Embedded Software Operation. “Using the World Wide Web infrastructure that’s already in place, developers can use today’s protocols and standards for user-to-appliance and appliance-to-appliance communication. Our ChaiServer and Chai Developer Kit were designed with Web standards built in, thereby enabling embedded-software developers to rapidly create the software needed to bring intelligent appliances to market.”

ChaiVM Version 2.0

HP also announced the availability of its ChaiVM 2.0 for the embedded-appliance community. ChaiVM 2.0 adds support for graphical user interfaces and enhanced permissions-based security. ChaiVM is a virtual machine that complies with the Java Virtual Machine specification. HP ChaiVM 2.0 allows for Java-language-based logic mobility in embedded appliances, making it more cost effective to write, extend and update embedded applications. For example, by building their applications to the ChaiVM, an ISV can write downloadable applications that could execute on a family of appliances, regardless of operating system or CPU differences.

Availability and Pricing

The ChaiVM 2.0, ChaiServer 2.0and Chai Developer Kit are all available from HP today. Pricing is customized.

The ChaiVM also is available from ISI, Lynx, QNX, Microware, Microsoft(R), Aplix and Enea OSE for their operating systems and from HP for other environments.
