Adding a web GUI to the controller

Overview

Orca uses Velocity template engine to drive the GUI. Adding a GUI to the controller involves writing template files that will present the different views for the controller and connecting it to the controller logic.

Connecting controller to the GUI

  • In the factory for the controller, you need to specify the portal

plugin class that goes with it. The portal plugin class has a method getMainTemplate() that returns the path to the controller's main web template. In the context of the interdomain controller it is /interdomain/main.xml. This is so because of the way we package the controller, evertything under resources/web is copied in the package and then put under the webapp dir in tomcat. So if you make a copy of these files under resources/web/xmlrpc/, your portal plugin should return /xmlrpc/main.vm. (See InterDomainControllerPortalPlugin?.java and InterDomainControllerFactory?.java).

  • In addition to the portal plugin class you will need to define a

ManagerObject?, a proxy interface to the manager object and an implementation of this interface using local communication. The interdomain controller does all this.

  • Once these are in place, the templates will be able to acquire the

proxy object and can talk with the manager object.

InterdomainController? is a good source of examples on how it is done.
