This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
I've concentrated the code to its barest essentials to illustrate my problem as clearly as I can.
My addAssignment.jsp is showing the header "Messages" when the LinkedList should be, and appears to be, empty. If there are no messages in the LinkedList, I expect the logic:present tag to preclude the printing of the header "Messages". How do I prevent the header "Messages" from printing if there are no messages in the LinkedList?
The struts-config file
The LoginAction file illustrates how I use the LinkedList. Also, the LoginAction works correctly with the Login.jsp page, the LinkedList and the Logic and Bean tags. That is, when error messages were present in the LinkedList, the Login.jsp page showed them corretly under the header Messages.
