You can set any Nucleus component and Dynamic Bean to a variable that can then be referenced by the JSP Expression Language (EL). The DSP tag library provides three tags for setting components to EL variables:
dsp:getvalueofenables access to standard JavaBean components, page parameters and constant values.dsp:tomapenables access to non-standard Dynamic Beans—for example, a RepositoryItem.dsp:importbean, which imports Nucleus components into a JSP, can also be used to set standard Java Bean components to EL variables.
