graphically construct client applications.

JoltBeans provide a JavaBeans-compliant interface to Jolt for NonStop

TUXEDO. A fully

functional Jolt client can now be developed without writing any code. You can drag and drop

JoltBeans from the component palette of a development tool and position them on the Java form

(or forms) of the Jolt client application you are creating. You can populate the properties of the

beans and graphically establish event source-listener relationships between various beans of the

application or applet.

Typically, the development tool is used to generate the event hook-up code, or you can code the

hook-up manually. Client development using JoltBeans is integrated with the Jolt repository,

providing easy access to available NonStop

TUXEDO functions.

ASP and JSE Connectivity for NonStop

TUXEDO

The Jolt ASP Connectivity for NonStop

TUXEDO Toolkit is an extension to the Jolt 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 NonStop

TUXEDO services.

The Jolt ASP Connectivity for NonStop

TUXEDO provides an easy-to-use interface for

processing and generating dynamic HTML pages. You do not need to learn how to write

Common Gateway Interface (CGI) transactional programs to access NonStop

TUXEDO

services.

The connectivity for JSE provides similar capabilities for servlets running in a servlet engine to

access Jolt for NonStop

TUXEDO.

Both ASP and JSE offer session pooling, load balancing, and help with HTML generation that

is written back to the client.

Jolt Server and Jolt Client Communication

The Jolt system handles all communication between the Jolt server and the Jolt client using the

Jolt Transaction Protocol. The communication process between the Jolt Server and the Jolt

client applet or applications functions as follows:

NonStop

TUXEDO service requests and associated parameters are packaged into a

message buffer and delivered over the network to the Jolt Server.

The Jolt Server unpacks the data from the message and performs any data conversions

necessary, such as numeric format conversions or character set conversions.

The Jolt Server makes the appropriate service request to the application service requested

by the Jolt client.

The service request enters the NonStop

TUXEDO system and is executed in exactly

the same manner as requests issued by any other NonStop

TUXEDO client.
