JoltBeans Class Library Walkthrough
This walkthrough describes how to build an applet that you use to:
- Enter an account ID
- Click on the Inquiry button
- Display the balance of the account (shown in the following figure)
The following figure shows an example of a completed Java form containing JoltBeans. The applet implements the client functionality for the INQUIRY service of the BANKAPP sample that is included with Oracle Tuxedo. To run this sample, the Oracle Tuxedo server must be running.
