You can also do this by sub classing all your actions from a base action of
some sort.
This would allow for better code reuse.
BaseAction.java
----------------
import org.blah.blah.blah.Something
abstract public class BaseAction extends Action{
...
...
abstract public ActionForward doPerformOrExecute( ActionMapping mapping,
ActionForm form,
HttpServletRequest request
)
...
...
// perform or execute - depending on your version
public ActionForward perform(ActionMapping mapping,
ActionForm form,
HttpServletRequest request,
HttpServletResponse response)
throws IOException,
ServletException
{
...
...
try{
//calling my own abstract method
this.doPerformOrExecute(mapping, form, request);
}
catch (Exception e) {
//I've also seen these broken out by every conceivable exception with
private handler methods for each case.
log.debug("Oh crap!!!");
// e.printStackTrace();
}
//could do finally or just let it flow
closeConnexion();
return mapping.findForward("success");
...
...
...
Having abstract base actions has cut out a lot extra overhead in all of my
struts projects.
Good Luck!
