Jolt 1.2 Developer's Guide

Jolt Server Handler (JSH). Manages network connectivity, executes service requests on

behalf of the client, and translates NonStop

TUXEDO buffer data into the Jolt buffer

and vice versa.

●

Jolt Repository Server (JREPSVR). Retrieves Jolt service definitions from the Jolt

Repository and returns the service definitions to the JSH; also updates or adds Jolt service

definitions.

Figure 1-2 illustrates the Jolt Server and Jolt Repository components.

Jolt Class Library

The Jolt Class Library is a set of classes you can use in your Java application or applet to make

service requests to the NonStop

TUXEDO system from a Java-enabled client. These Jolt

classes allow you to access NonStop

TUXEDO transaction services using objects.

When developing a Jolt client application, you only need to know about the classes that Jolt

provides and the NonStop

TUXEDO services that are exported by the Jolt Repository. Jolt

hides the underlying application details. Using Jolt and Jolt's Class Library, you do not need to

understand the underlying transactional semantics, the language in which the services were

coded, buffer manipulation, the location of services, or the names of databases used.

The Jolt API is a Java class library: applets are downloaded dynamically and are only resident

during runtime. As a result, there is no need for client installation, administration, management,

or version control. If services are changed, the client application recognizes the changes at the

next call to the Jolt Repository.

Figure 1-3 shows the flow of activity from a Jolt client to and from the NonStop

TUXEDO

system. The call-out numbers correspond to descriptions of the activity in Table 1-1. The host

NonStop

TUXEDO environment in the figure is the Open System Services (OSS)

environment on a Compaq NonStop

Kernel system.
