Your service ID is not the same as your class name. Try:
<contribution
configuration-id="tapestry.services.ApplicationServices">
<service name="bip" object="service:BipService"/>
</contribution>

Subject: Re: File download - LinkFactory not being set (statup exception
now)
Tweaked my hivemodule.xml to the following:
<service-point id="BipService"
interface="org.apache.tapestry.engine.IEngineService">
<invoke-factory>
<construct class="com.kodak.mis.web.engine.BipService">
<set-object property="linkFactory"
value="service:tapestry.url.LinkFactory"/>
</construct>
</invoke-factory>
</service-point>
<contribution
configuration-id="tapestry.services.ApplicationServices">
<service name="bip"
object="service:com.kodak.mis.web.engine.BipService"/>
</contribution>
Changed contribution/service/object from instance:... to service:....
Thought that simple fix would resolve it, however I now get:

My class is compiled and deinitely in the classpath. If I remove:
<contribution
configuration-id="tapestry.services.ApplicationServices">
<service name="bip"
object="service:com.kodak.mis.web.engine.BipService"/>
</contribution>
then it reads everything in ok but the page which uses this
engine/service doesn't work.
Any pointers on what I am missing?
