Get TransactionManager for the given configuration. If we previously created a TransactionManager for the same configuration instance we need to return the same TransactionManager instance. Therefore this method needs to be synchronized and we need to use a IdentityMap.

Parameters:

jdoConf - The configuration we need a TransactionManager for.

Returns:

The TransactionManager.

Throws:

MappingException - If any failure occures at creation of TransactionManager.
