Web Enabling Your HP 3000

Three-tier ultra-thin client model

If high performance is critical, the ultra-thin client offers an attractive option. In this model,

business logic is moved up from the client to the application server on the Web server, and the

JDBC client is run from the Web server to the back-end database. The Web application server or

servlet appears as the client to the JDBC driver client and connects to the enterprise database

via the JDBC server on the database server.

Other JDBC drivers are also available on the HP e3000:

• JDBC driver from MiniSoft lets any programmer write applications in Java to access MPE

flat files, KSAM files, Image, and TurboIMAGE databases using standard SQL statements.

• Advanced Network Systems ADBC Developer’s Kit links browser applets and server appli-

cations written for the MPE/iX Java Virtual Machine directly to TurboIMAGE databases. This

tool gives HP e3000 developers a way to make existing HP e3000 applications Internet-ready

using native IMAGE intrinsic calls.

With the support of Apache Web server and Java (part of FOS beginning with MPE/iX 6.0) on

the HP e3000, JDBC will increase the new applications development on the HP e3000.

Businesses can easily continue to use HP e3000 databases and access information on the web.
