How can TopLinks TypeConversionMapping be customized to make use of a third party class?
TopLink provides a rich set of type conversions between database types and the Java types provided with JDK. It is possible to make use of additional or third party types in a domain class through customization of TopLink. TopLink makes use of a singleton ConversionManager (found in the oracle.toplink.helper package). Developers can subclass this class and create a custom conversion manager with the additional conversions required. At system startup an instance of this class must be provided as the singleton conversion manager.
