calling getter methods

["G.L. Grobe" <ga...@grobe.org>]

I can see that for a radio tag, the property is the name of the bean that
was mapped in the struts-config.xml file. But how does the getter method in
the action form bean actually get called, or how does the app know which
getter method to use?

I have a working example where my  action does a getXXX on the form action,
but I don't know how it got filled in and would like to understand that.

Also, I found using the debug level (and adding my own
debug messages where needed) to be useful in seeing
when things are getting called.

Basically, Struts follows rules very similar to what the standard

	<jsp:setProperty name="beanname" property="*"/>

tag does.  It looks at the request parameters, and matches them up with
JavaBeans and setter methods, as long as your bean's setter methods match
the rules in the JavaBeans specification.  In most cases, that means a
proeprty named "foo" will look for a setter named "setFoo" -- but see the
JavaBeans Specification for more info.
