JDBC and waiting for commit on a locked table in 6.4.2

Hello,

I'm using JDBC PostgreSQL with 6.4.2 database.

I'm using the new code style (conn.setAutoCommit(false)).

When the transaction is waiting for another transaction to terminate, is
there a way to set a timeout period , let's say a maximum of 30 seconds
?
If the lock still persist after 30 seconds the statement.upDate() to
fail and to throw a SQLException?

Of course, without the classical watchdog thread object.

Thanks in advance,

(BTW : I tried the same thing on 6.5 beta 1 and my both transactions
have committed without problem. Nice work that MVCC. I'm watching daily
the development waiting for the big day of 6.5 final)

Best regards,
