The JSP Expression Language (EL) allows you to quickly access data stored in JavaBeans components. JSP EL allows you to create both arithmetic and logical expressions.

EL Benefits:

  • The EL tag has a shorter syntax than the standard JSP tag. You can use EL to access nested properties. You can use EL to access collections like maps, arrays, and lists.
