EspañolEXPRESSION LANGUAGE
'Expression Language' (EL) is a scripting language to allow access Java components (JavaBeans) through JSP. Since JSP 2.0, it is used inside JSP tags to separate Java code from JSP, and to allow easier access to Java components (than in Java codes).
★ OGNL- An open source expression language used by WebWork (and Struts 2.0).
Evolvement of EL occurred to make scripting more easier for web-content designers who have little or practically no knowledge of the core Java Language. This scripting language makes JSP a scripting language in the true sense. Before EL, JSP consisited of some special tags like scriplets, expressions etc within which java code were written explicitly. With EL the web-content designer must only know to make proper calls to the core Java methods and just enjoy the true scripting flavour of a scripting language.
