I did this recently. I simply wrote a base action class which extends
the struts Action class. Here's the code snippet:
public ActionForward execute(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception {
if(form!=null) {
trimFormFields(form);
return(executeAction(mapping,form,request,response));
}
abstract ActionForward executeAction(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws Exception;
protected void trimFormFields(ActionForm form)
throws Exception {
Map properties = PropertyUtils.describe(form);
Iterator it = properties.keySet().iterator();
String property; Object value;
while(it.hasNext()) {
property = ((String)it.next());
value = PropertyUtils.getSimpleProperty(form,property);
if(value!=null && value instanceof java.lang.String) {
PropertyUtils.setSimpleProperty(form,property,((String)value).trim());
}
}
}
So whatever common action logic I want all my actions to perform, I
placed inside of BaseAction's execute() method. Then I extend the
BaseAction by creating an executeAction body in all subclasses. Then
when the action is invoked, BaseAction takes care of trimming all form
properties which were defined as string types. This has been working
quite well for us for sometime now.
Hope this helps,
Chris

Subject: Is there a way to auto-trim String properties in DynaForms?
I'm reposting this in the hopes that there is an answer out there.
