Subject Re: CommitRequired attribute of transactionManager in iBatis 3
Date Thu, 28 Jan 2010 20:22:59 GMT
In iBATIS 3, you can use .commit(boolean force)

The advantage is that you need not incur the performance penalty for every
transaction, and also, it allows frameworks like spring to declaratively
configure transactions to be forcefully committed.

Your thoughts?
