Custom Webjects
The following topics describe custom webjects, which allow an application developer to extend the functionality of the Info*Engine server by writing custom Java code. Custom webjects are simply user-defined webjects that get dynamically loaded by the Info*Engine server. These webjects are then available to any task or template, and have access to all internal classes of the Info*Engine server.
There are two kinds of custom webjects:
Custom display webjects are used to format group information. A custom display webject has all the capabilities of standard display webjects.
Custom group webjects are used to manipulate and transform group data into other groups. A custom group webject has all the capabilities of the standard Info*Engine group webjects.
