It's the javabean specification. Normally the methods "getFoo()" and "setFoo()" operate on the property "foo". The code doesn't really care what the property is called internally (it could even be calculated on the fly), but it infers the property name from the method name.
Normally variables in java begin with a lowercase letter. See Sun's java coding standard for more, or William Wake's "Java Coding Standard on One Page" http://www.xp123.com/xplor/xp0002f/index.shtml The method "getCheckPart()" will refer to a property named "checkPart". > -----Original Message----- > From: Francisco Exposito Aguilera [mailto:[EMAIL PROTECTED] > Sent: Wednesday, July 26, 2006 2:15 PM > To: user@struts.apache.org > Subject: RE: Error with c:for Each and c:out > > > Thanks a lot George!!!!
