Ok, first thing right off. You do not need to subclass BaseEngine. The
steps are :
1. Your class implements org.apache.tapestry.services.DataSqueezer.
2. Setup your class as a service in hivemodule.xml:
3. Then contribute to the tapestry.data.SqueezeAdaptors configuration
point, put something like this in your hivemodule.xml:
<contribution configuration-id="tapestry.data.SqueezeAdaptors">
<adaptor object="service:YourAdaptor"/>
</contribution>
if you look at tapestry-4.0.jar!/META-INF/tapestry-data.xml, you will see
how this all works. The examples there are based on "instance:" but you can
use "service:"

Subject: T4 DataSqueezer/SqueezeAdaptor, Spring & Hibernate
Hi,
I've written a SqueezeAdaptor for use with my Hibernate entities and it
works well in T3.
My HibernateSqueezeAdaptor unsqueezes the string by decoding a entity
type code along with the id, then it accesses my Spring appService bean
and asks it to retrieve my entity.
I'm attempting to upgrade/convert to T4 and I'm a bit stumped as how to
do the conversion.
How do I create and register a SqueezeAdaptor that uses a Spring service
object, what do I put in my subclass of BaseEngine?, do I need to
subclass BaseEngine? How do I inject my spring service into my adaptor?
Do I need a hivemodule.xml? if so what do I put in it?
What would be the logical steps needed to implement this. Also is there
any security issues with what I'm doing?
Many thanks
Adam.
