Re: Configuration Question

I thought of that but the thing is most of the app is identical between the two versions. It seems overkill to create seperate jars for the two customers. I'm also trying to introduce hivemind incrementally into the project. The current way of configuring things is to use property files that sit outside of the main webapp (on the classpath). Can hivemodule.xml be read from any location other than WEB-INF?

make an interface jar, customer a and customer b jar. The interface jar

contains the implementation declarations.

Kind of like this

interfaces.jar!META-INF/hivemodule.xml

   <service-point id="ObjectFactory"
   interface="my.package.ObjectFactory">
   </service-point>

customera.jar!META-INF/hivemodule.xml

   <implementation service-id="my.package.ObjectFactory">
       <invoke-factory model="singleton"
service-id="hivemind.BuilderFactory">
           <construct
           class="my.package.customera.ObjectFactoryImpl">
           </construct>
       </invoke-factory>
   </implementation>

customerb.jar!META-INF/hivemodule.xml

   <implementation service-id="my.package.ObjectFactory">
       <invoke-factory model="singleton"
service-id="hivemind.BuilderFactory">
           <construct
           class="my.package.customerb.ObjectFactoryImpl">
           </construct>
       </invoke-factory>
   </implementation>

Depending on which customer you are configuring, you throw the correct jar
of implementations in the class path and away you go. We use it quite
sucessfully.

Subject: Configuration Question

I have the following situation.

We have one application code base that is configured differently for two (or more in the future) different customers.

Say I have interface Foo and two implementations that implement that interface - one for each customer. What's the best way of configuring these sorts of differences?

Is there any way of saying in hivemind that I prefer one service implementation over another in HM?
