Hi all,
I am writing in the hope that someone like me have to face the same problem:
Retrieve an attribute that is inside a bean contained in the pageContext using a string key, such as those used in a JSP expression language (eg ${beanName1.beanName2.attribute1}). My intent is to use strings like that: "beanName1.beanName2.attribute1" to retrieve variables in the session or request, within a Custom Tag.
I do not having to reinvent the wheel.
