Examples of JtxTransactionManager

jodd.jtx.JtxTransactionManager
{@link JtxTransaction} manager is responsible for handling transactionpropagation and resource managers. Holds various JTX configuration data.
Note that transactions are hold inside a thread-local transaction stack. Therefore, if one transaction is created after the other during the same thread, the second transaction will be aware that it is 'after' the first one.
