RE: General Question
Since you are more than likely retrieving a data access object to set up the form object, why not just keep it hanging around in some kind of cache (application scope should do), and then compare it with the values that user submits to see what they changed. -Dave -Original Message- From: Vinay [mailto:[EMAIL PROTECTED]] Sent: Monday, February 10, 2003 2:27 PM To: Struts Users Mailing List Subject: General Question This is a very general question and not specifically related to struts or tag libraries, may be naive,thought somebody could help me off the list on the list.

RE: General Question
No, just update your database table with all the fields that come back on the form. If a field has changed, that value will be updated. Otherwise, the same value will be written to the table and you will be no worse off.

RE: General Question
You may need to elaborate; but I think you might want to double the fields to compare the original against the editable if you want to keep the transaction request based, otherwise you might want to use the Unit of Work or Memento pattern in managing the transaction.

Re: General Question
Well first you might find that updating all the fields is easier, but still if you want to do it your way, you have to have something to compare the old value to the new one, and in that case you use a hidden field. So you'd have something like: input type=text name=field1 input type=hidden name=oldField1 When the user hits submit you'll have to check to see if the values are the same, if they are ignore and don't update otherwise update. You see you have to loop over all the fields anyway, it's a form submit thing, you can't tell it to submit a form partially.

RE: General Question
If you want to go client side, you could pass a list of fields that were modified by the user from the browser, as opposed to passing all the original values which you should already know. Easy enough to put an onChange event handler into a field and it this field to list of changed fields, but what if they change it back? Well, you can store the original values in an array and then onSubmit do the comparisons, set up the hidden changedFields input and bingo, a cheap hack ... ahem a solution to the problem. I'm still partial to making the comparisons at the web tier. It's cleaner and easier to maintain. Plus a little reflection magicks could go a long way towards creating the: public static List gimmeDifferent(Object dao, Object form) throws BiffDontConMeException method. -Dave -Original Message- From: Robert S.

Re: General question regarding transport-guarantee CONFIDENTIAL, can struts help?
Alex, A group of developers (including me) have done some work in this area. The basic idea is that you indicate which Struts action mappings should be accessed securely, and then use our extensions to various Struts tags when you link or submit forms to them. Our extended tags recognize that the specified action should be secure, and write out an absolute URL with the appropriate protocol (HTTP or HTTPS) and port number. Our extended tags will also get you back to HTTP when you return to a non-secure action. You can download the extension here: http://struts.ditlinger.com/ -Max - Original Message - From: Alex Paransky [EMAIL PROTECTED] To: 'Struts Users' [EMAIL PROTECTED] Sent: Wednesday, February 27, 2002 10:16 PM Subject: General question regarding transport-guarantee CONFIDENTIAL, can struts help?

Now, these pages cannot be accessed using http unless we hardcode https://www.server... in our URLs. However, we are trying to keep our URLs relative and not absolute. Is there anything in STRUTS that could help us automatically switch in to https for those pages marked with transport-guarantee CONFIDENTIAL configuration?
