| Action | | public interface Action (Code) | | All actions may implement this interface, which exposes
the execute() method. However, as of XWork 1.1, this is
not required and is only here to assist users. You are
free to create POJOs that honor the same contract
defined by this interface without actually implementing
the interface.
