Do JTS implementations support nested transactions?

If a client begins a transaction, and within that transaction begins another transaction, the latter operation will throw a NotSupportedException if the JTS implementation does not support nested transactions. Keep in mind that even if the JTS implementation supports nested transactions, this transaction manager-level support does not guarantee support for nested transactions in an application. For example, the EJB 1.1 specification does not support nested transactions.
