I know how to pass a hidden field. The problem is how
to retrieve it in my Java class. I have illustrated
that my Java class does not extend HttpServlet or
Action.
This Java class has a mapping in the struts-config.xml
file:
type="org.apache.struts.scaffold.ProcessAction"
parameter="org.XYZ.article.FindEditorData"
name="articleForm"
