I am running in to a problem when trying to set up a bean jsp page. I get the error /WEB-INF/EnterItem.jsp(15,66) jsp:getProperty for bean with name 'itemID'. Name was not previously introduced as per JSP.5.3.







What could be the cause of this?

"Name was not previously introduced" indicates that you haven't told your JSP about this bean as of yet.

The "name" of the bean used in the jsp:getProperty tag should match the "id" of the bean in the jsp:useBean tag.
i.e.:



Your useBean references an id of "itemBean"
Your getProperty references a name of: "itemID"
Your BeanMaker class stores a request attribute of "item"

These three values should presumably be the same.
