WebAdmin is the basic application which allows managing users and groups in Omero server. WebAdmin was build by the Java Server Faces (JSF), which is a Java technology-based Web application framework that simplifies the development of user interfaces for Java EE applications. Unlike to other traditional request-driven Model-View-Controller web frameworks, JSF uses a component-based approach. The state of UI components are saved when the client requests a new page and then they are restored when the request is returned. Out of the box, JSF uses Java Server Pages for its display technology, but JSF can also accommodate other display technologies. JSF includes:

• A set of APIs for representing user interface components and managing their state, handling events and input validation, converting values, defining page navigation, and supporting internationalization and accessibility.
  

• A default set of user interface components.
  

• A server-side event model.
  

• State management.
  

• Managed Beans (Java Beans created with dependency injection).
