Traditionally, custom tags are used to access logic and data from within JSP pages. With the integration of the expression language (EL) into the JSP 2.0 standard, many custom tags have become obsolete. Consequent usage of EL expressions in combination with the Java Standard Tag Library (JSTL) may now lead to very nice JSP code. Calyxo supports this approach by providing so-called accessors, that present themselves as a hierarchy of beans and maps, ready to be used in EL expressions.
Beside implementing various concrete accessors, the Calyxo Base component provides the Access API, which may be used by application programmers to contribute their own accessors.
Please refer to the Accessors reference to explore the accessors provided by Calyxo Base.
