NonStop Server for Java 5.0 Programmer's Reference

NonStop Tuxedo: Jolt Client

The Jolt product is a Java based interface to the HP NonStop Tuxedo system that extends

Tuxedo services to the Internet. Jolt allows you to build client programs and applets that can

remotely invoke existing NonStop Tuxedo services allowing application messaging, component

management, and distributed transaction processing.

With Jolt, you can leverage existing Tuxedo services and extend your transaction environment

to the corporate intranet or world-wide Internet. The key feature of the Jolt architecture is its

simplicity. Using Jolt, you can build, deploy and maintain robust, modular, and scalable

electronic commerce systems that operate over the Internet.

The Jolt product includes the JoltBeans toolkit, which provides a JavaBeans compliant interface

to Jolt for NonStop Tuxedo. The JoltBeans toolkit contains beans that wrap the existing Jolt

class library into reusable bean components, such as the JoltSessionBean or the

JoltServiceBean. These beans can be customized easily by giving application specific values to

properties and connecting them with other bean components. You can use the JoltBeans toolkit

with your Integrated Development Environment (IDE) to create Jolt clients that can access a

Tuxedo application.

The Jolt product includes the Jolt Web Application Services Toolkit, which is an extension to

the Jolt 1.1 Java class library. The Toolkit allows the Jolt client class library to be used in a

Web Server to provide an interface between HTML clients or browsers, and Tuxedo services.

Library.

Stored Procedures in Java

Stored procedures in Java (SPJs) provide an efficient and secure way to implement business

logic in an SQL/MX database. They allow you to write portable applications in Java and access

an industry-standard SQL database.

A SPJ is a type of user-defined routine (UDR) that operates within a database server. A UDR

can be either a stored procedure, which does not return a value directly to the caller, or a

user-defined function, which does return a value directly to the caller. (A stored procedure

returns a value only to a host variable or dynamic parameter in its parameter list.)

In the SQL/MX database, a SPJ is a Java method contained in a Java class, registered in

SQL/MX, and invoked by SQL/MX when an application issues a CALL statement to the

method.

For detailed information on using SPJs, see the SQL/MX Guide to Stored Procedures in Java in

the NonStop Technical Library.
