Within Seam, components are simple POJOs. There is no need to implement any interfaces or derive classes from a Seam-specific base class to make Seam components classes. For example, a Seam component could be:
Seam components are defined by adding the @Name annotation to a class definition. The @Name annotation takes a single parameter to define the name of the Seam component. The following example shows how a stateless Session Bean is defined as a Seam component called calcAction.
package com.davidsalter.seamcalculator;
@Stateless
@Name("calcAction")
public class CalcAction implements Calc {
...
}
