Firstly - place such questions to the struts-user list, please.
Common solution to fill form with values from database is to create
Action class and appropriate mapping for it -
public class ReadAction extends Action {
... some stuff to read values from database, create or retrieve
ActionForm bean, fill it with values and store this bean in
request or session. Return 'success' forward if all is ok and
'error' if any errors.
}
and map this class to the read.do path, for example.
<action path="/read"
type="org.somepackage.ReadAction"
attribute="someForm"
scope="request"
validate="false">
<forward name="success" path="/viewValues.jsp"/>
<forward name="error" path="/error.jsp"/>
</action>
viewValues.jsp form contains form 'someForm'.
