Erik: Here's an example:
In your Action class do:
try {
service.insertEmployee( employeeDTO );
ActionMessages messages = new ActionMessages();
ActionMessage message = new
ActionMessage("message.employee.insert.success",employeeDTO.getName() );
messages.add( ActionMessages.GLOBAL_MESSAGE, message );
saveMessages( request, messages );
request.setAttribute("employee",employeeDTO);
return (mapping.findForward("success"));
}
catch( DatabaseException de ) {
ActionErrors errors = new ActionErrors();
ActionError error = new ActionError("error.employee.databaseException");
errors.add( ActionErrors.GLOBAL_ERROR, error );
saveErrors( request, errors );
return (mapping.findForward("error"));
}
In your success.jsp:
