Hey all, Forgive a newbie his questions!
I'm trying to understand a bit of struts and I'm having one key problem. When a with a form jsp runs, there may be dynamic data there that is not related to user input directly. Examples might include the 'step number' in a wizard or perhaps some values for a drop down menu for the user to choose from. >From experience, it's important to have a data transfer object type of class to provide to the jsp with the necessary data enclosed. The key here is that you don't want the jsp hitting any back end pieces that might require a network or db hit while the jsp is displaying. Otherwise, you may get a peculiar error (network down? database crash?) when the jsp is half way done rendering. Since the output of the jsp can be streamed out, you may get a partial HTML page and then some wacky attempt at a clean error page. It doesn't look nice. So I've been trying to figure out how Struts might handle this concept. The closest I've come to an answer is the ActionForm, but.. it has problems: 1) Are ActionForms only supplied (in the request) to the jsp after the first request (i.e., only if the validation routines found an error). 2) How can I 'prepare' my ActionForm with data the jsp requires (such as the page number or the values for a drop down menu)?
