Class InitParameters

  • All Implemented Interfaces:

    Serializable


    public class InitParameters
extends Object
implements Serializable

    Constants for all servlet init parameters. Keeping them in a separate class allows using reflection to expose the parameters in the Spring add-on.

    Note: do not add other constants than String constants representing init parameters here.
