Class CCELResolver

java.lang.Object
jakarta.el.ELResolver
org.eclnt.jsfserver.util.CCELResolver
public class CCELResolver extends jakarta.el.ELResolver
This class wraps the default expression resolver in order to wrap the getting/setting functions with some additional functions.

(1.) Interface IPropertyTypeResolver during getType(..) call.
(2.) Interface IAcceleratedPropertyAccess during getValue(..) call.
(3.) Hot Deployment Management.
(4.) Possibility to (re-) set a managed bean at runtime.
(5.) Before setting property values the interface IPropertyValueConverter is called, if available.


The functions of this class were part of the CaptainCasa-specific variable and property resolver with JSF 1.1 - due to changed from JSF 1.1 to JSF 1.2 they were shifted into this class...

  • Constructor Details

    • CCELResolver

      public CCELResolver(jakarta.el.ELResolver delegateTo)
      Default constructor to be used in normal Servelt/JSF environment.

    • CCELResolver

      public CCELResolver()
      Sepcial constructor to be used in mini server environment. In this scenario there is no delegation possibility. And in this scenario all expressions need to be resolved through the CCELResolver (i.e. there is NO resolution of e.g. "d" by the resolver of the servlet/JSF environment.
