Using a PreparedStatement accross transactions

Question

How can I use a PreparedStatement object across multiple transactions?
Every transaction uses a dedicated jdbc connection, and all database interaction
needs to use this connection object in order to participate in the transaction.
So, if I do:
PreparedStatement ps = conn.prepareStatement("...");
the prepared statement object is tied to "conn". Can I use this prepared statement
object in other transactions that are using other connections? There is no method
to reset the connection object in PreparedStatement.
Am I totally missing the point here?

weblogic can do for you, under the covers. How are you getting your connections?
If they come from a weblogic transaction-aware DataSource or the jts driver, and the
transaction is being managed by the weblogic transaction coordinator, we have you
covered.
You should create your PreparedStatements as you show, wherever you need them.
You cannot pass a statement around, or retain it across transactions, but if you get
your connection from our pool, the pool transparently caches prepared statements
with the connection they came from, and when your code does a prepareStatement(),
we transparently return a currently-unused cached statement for that SQL, if it exists.
