Easiest way is to throw the exceptions outside the bean, and define what pages those exceptions go to in the struts-config.xml file. > Keeping in > mind that the decision to forward to an failure action is to > be done within > the Form Bean here. > > I am also interested in knowing if this is the correct > approach to have the > form bean make such calls. If not, then kindly suggest a better > implementation. Probably not. Much better to have the action setup the form bean and use the form bean strictly for display purposes. Better yet the form bean is nothing but Strings for it's properties so your form will work as expected by the user (see other discussions and/or husted site for more detials). > > Regards, > Muhammad Momin Rashid. > > "Robert Taylor" <[EMAIL PROTECTED]> wrote in message > news:[EMAIL PROTECTED] > > Define success and failure forwards in your struts-config > file for the > > specified action. > > > > In the action class (which should delegate to a business object), > > retrieve the data.
