This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
As you are using JSTL 1.0 I will assume that you are using a JSP 1.2 or earlier container. In that case, then no. There is no provision in the version of the EL provided by the JSTL 1.0 to find the length of q string or anything else.
Under JSP 2.0, the EL is augmented with functions, and the JSTL 1.1 provides a length function. [ November 11, 2005: Message edited by: Bear Bibeault ]
