JSTL to Java Scriplet

Scope:

When you want to use an EL variable exposed by a JSTL tag in an expression in the page’s scripting language, you use the standard JSP element jsp:useBean to declare a scripting variable.

Solution Example:

<!-- first set the desired jstl variable and then export it to java -->
<c:set var="productGroup" value="${product.productGroup}"/>
<jsp:useBean id="productGroup" type="java.lang.Integer"/>

<!-- then simply access it in java -->
<%= ProductGroup.getDisplayName( productGroup ) %>

… that’s it.
Wa’Allahu A’lam.
