Hello!
I have a problem mapping a hashtable to the database (MySQL). The problem is when I try to get an object from a table in which there exist any property hashtable.


firstly, in my mapping archive I put this:
<property name="configuration"/>
But my application failed at the time where is a query to get an object of the table where this property is and threw and exception: org.hibernate.type.SerializationException: could not deserialize

next, I changed the mapping file to:
<property name="configuration" type="binary"/>
and this time the exception was: org.hibernate.AssertionFailure: null id in bbdd.ConfigObject entry (don't flush the Session after an exception occurs).

Where is the problem? What is the value type to map a hashtable??

This application goes perfectly well with hsqldb.

Thank you very much for your time.
