The following table briefly describes the flow of activity involved in using the Jolt Class
Library to access TUXEDO services.
Table 1-1. Using the Jolt Class Library
Process Step Action
Connection 1. A Java enabled Web browser downloads an HTML page using the HTTP
protocol.
2. A Jolt applet is downloaded and executed in the Java Virtual Machine on
the client.
3. The first Java applet task is to open a separate connection to the Jolt
Server using a private protocol.
Request 4. The Jolt client now knows the signature of the service (such as, name,
parameters, types) and can build a service request object based on Jolt
class definitions, and make a method call.
5. The request is sent to the Jolt Server, which translates the Java based
request into TUXEDO requests and forwards the request to the
TUXEDO environment.
Reply 6. The TUXEDO system processes the request and returns the information
to the Jolt Server, which translates it back to the Java applet.
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:
TUXEDO service requests and associated parameters are packaged into a message buffer 1.
