Here's one possible solution:
Serialize the shopping cart to a database or disk file each time it changes.
Encode the links between sites with a 'key' parameter that tells the other
site that you are 'shopping around'.
The key would contain a (perhaps not _the_) session id used in the
serialization in step one along with a 'site id' to identify the site that
is current shopped at.
The second site, when it gets a request with a key, would post a query to a
servlet on the first site, including the session id from the key in the
query.
The servlet on the first site would retrieve the cart from the database and
send a response back indicating the cart's contents (perhaps an XML
response, like a mini version of SOAP).
There are all kinds of issues with this that you'll have to consider.
You'll have to have a system of authorizing requests to your communication
servlets so not just anyone can post to them and get responses. You'll have
to have some way of synchronizing databases between sites so that shopping
cart information is meaningful between sites, etc.
