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.  Check either Design
Patterns from GoF or Fowler's Patterns of Enterprise Application
Architecture.

Actually this might be an idea i might want to go for at this moment
without needing to  storing object in the application scope.
Thanks a lot Robert , but if there are still any ideas of doing this in
other ways would  be very helpful.

RE: General Question

2003-02-10 Thread Durham David Cntr 805CSS/SCBE 
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.

Re: General Question

2003-02-10 Thread Robert S. Sfeir 

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:




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.

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.

Unless this is exactly what you are trying to avoid?

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.

Re: General question regarding transport-guarantee CONFIDENTIAL, can struts help?

2002-02-27 Thread Max Cooper 

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/
