this is a very basic application of the JavaBeans spec, and I don't really think you should read it to use in jstl. You just need to know that any class with non-static methods starting with "get", "set" or "is" (this last one only for booleans) is a JavaBean to you. Then, to call this method, remove the prefix and lowercase the first letter after it. Unless there are more than one uppercase letters, so:
getId() --> .id getID() --> .ID In most EL tutorials you'll find this better explained, I'd start with Shawn Bayern's book, JSTL in Action, probably the best there is for JSTL. -----Original Message----- From: Keith [mailto:[EMAIL PROTECTED] Sent: 12 April 2004 18:57 To: Tag Libraries Users List Subject: RE: isLast() method of LoopTagStatus class Perfect! Thanks! Where would I have looked to find that info? I'm still really new to Beans and raw Java code. Main reason why I'm going with JSTL right now. I had tried looking in the Java Docs, but I really didn't know where to begin.
