NHibernate Spring .NET adding advice to transaction proxy

Question

I am using Spring .NEt and NHibernate along with ASP .NET MVC.

Recently I decided to integrate transaction management with Spring. I understand spring give a way to easily integrate transation using the [Transaction()] attribute on your service. I got this to work.

My old architecture was to intercept calls to the service via advice using AOP and check if you were permitted to call this method.

CALL --> Tx Advice --> Permission Advice --> Service -- > execute logic --> Commit/Rollback Tx in Tx Advice --> End CALL.

Now, I no longer need the Tx Advice because of the Transaction() attribute on my service methods.

However, how do I make it so that the transaction gets started before it makes it to the PermissionAdvice.

File : services.xml

<property name="ObjectPersistenceManager" ref="ObjectPersistenceManager" />
<property name="StatisticsStandingsManager" ref="StatisticsStandingsManager" />

....
</object>

<tx:attribute-driven/>

File: Dao.xml

<object type="Spring.Objects.Factory.Config.PropertyPlaceholderConfigurer, Spring.Core">
<property name="ConfigSections" value="databaseSettings"/>

In the Spring documentation on declarative transaction management, I read that you can specify an order element on the attribute-driven tag.

Something like

<tx:attribute-driven transaction-manager="transactionManager" order="1" />

The value for order is used with the normal rules for aop advice ordering.
