>> he is asking how to store ojects using cookies?
Which leads me to believe they are/have been misdirected into how to persist data for what appears to be a user's session. Just made me curious. We could just answer the question at hand. However, if my assumption is correct, wouldn't they be better served by "experts" to guide them correctly? If I'm wrong, then store away.

Sorry for the delay....
Actually, I am using a session. Our users want to be able to refresh their session after it has expired by re-logging-in in a small pop-up. I currently have that implemented and it works well for single page forms. However, some of our forms cover multiple pages (tabs). I cache the form data from the other tabs as the user navigates the tabs and I use the cached form data to create a value object to send to the business tier when the user submits the last tab. When a user refreshes their session on a single page form, the form data is stored in the form fields in the html document. I want to store a serialized object in a cookie in order to store the form data from other tabs so if their session expires and they refresh it, I do not lose the form data from the other tabs.
Does that make sense? Can you think of another way to maintain this data after session expiration without creating a specialized DB table for each form?
you can simply use hidden fields to hold data in other tabs.
For example, if other tabs have data firstname, then you can store this value using:
<input type="hidden" name="firstname" value="<%=savedValue%>" />
That way, you don't need session also session might not be for you because you want to keep data even after session expires.
Enjoy :)

>> Is it possible to store a Java object in a client side cookie?
You might not directly store your java object but It is possible. say, you have java object which has properties:
String propA;
String propB;
Then you use 2 cookiesto store values for those values of 2 properties. In your code, you control how you retrieve and store between cookies and java object.
