I use jdbc connection pooling and transaction.
i set setAutoCommit to false to use the transaction. when i return this connection to the pool. i wonder if i need to set this connection's setAutoCommit to false, which means back to its normal status?
I think it really depends on the situation and your definition of "need". Technically it is not necessary; but it seems to me that returning it to the pool in the same state as it was when you retrieved it would be a good practice.
