[Building Sakai] Exception when using HibernateTransactionManager and ContentHostingService

Hi,
I have a custom tool that I'm busy writing in Sakai 2.7.
My service implementation extends HibernateDaoSupport so that I can make use
of the Hibernate Template to save data.
However, for one of my service calls I have to save a file to Sakai's
Resources as well.
This seems to work fine for ContentCollections (folders), but it I get an
exception when writing a file.
I used the following method call to try and create the file:
contentHostingService.addResource("dir", "file", ".txt", 3);
During this call, I get an exception. Seems like the ContentHostingService
makes use of DataSourceTransactionManager instead of
HibernateTransactionManager and that the 2 can't be mixed. Is there a way to
configure the ContentHostingService to make use of the same transaction
manager? Or is it another problem?
Here follows the exception:
org.springframework.transaction.IllegalTransactionStateException: Pre-bound
JDBC Connection found! HibernateTransactionManager does not support running
within DataSourceTransactionManager if told to manage the DataSource itself.
It is recommended to use a single HibernateTransactionManager for all
transactions on a single DataSource, no matter whether Hibernate or JDBC
access.
