-----------------------------------
workaround solution...
Configuration conf =...;
Properties oldprops=conf.getProperties();
Properties newprops=new Properties();
for (Object o:oldprops.keySet()) if
(!"hibernate.connection.datasource".equals(o))
newprops.setProperty(o.toString(), oldprops.getProperty(o.toString()));
conf.setProperties(newprops);
conf.setProperty("hibernate.connection.driver_class", clazz);
conf.setProperty("hibernate.connection.url", url);
conf.setProperty("hibernate.connection.username", user);
conf.setProperty("hibernate.connection.password", pass);
Provide a way to unset properties, and/or provide a 'none'
option for hbm2ddl.auto

Key: HHH-2019
URL: http://opensource.atlassian.com/projects/hibernate/browse/HHH-2019
Project: Hibernate3
Issue Type: Improvement
Environment: hibernate / annotations / hibernate.properties
Reporter: Dave E Martin
Priority: Minor
It may occasionally be desirable to programmatically get rid of or override a property
value, this is generally allowed for by the .setProperty method, however:
Once hbm2ddl.auto is set to something, there is no way to unset it, or set it to a value
which would be equivalent to its being unset (or its undocumented). There is no remove or
unset, or deleteProperty, and also setting it to null does not work.
Due to issues such as HHH-2018, it may be necessary to programmatically 'get rid
of' hbm2ddl.auto even if the end user (or some other mechanism) has specified a value
for it in an external hibernate.properties file (or other method of setting hibernate
properties).
