Struts2 does not have FormBeans anymore. All the form fields are
instance variables directly in your Action class. Simply include a
variable fieldName of type String with getters and setters in your
Action class. The setFieldName() method will be called when you submit
the form. In the execute() and validate() methods you can use the
fieldName variable directly.
What you can also do is put a instance variable of a bean in your
Action class. You can then acces the getters and setters of this bean
in the jsp:
<s:form action="myaction">
<s:select name="myBeanVariableName.fieldName"
theme="simple"
list="fieldList"
headerKey=""
headerValue="- - Please Select - -"/>
</s:form>
If you submit this form struts will call
myaction.getMyBeanVariableName().setFieldName(selectedValue).
