Hello everyone.

I am trying to learn more about the ECF and started with a simple 
example where there is a simple "echo" service, published by ECF and a 
client to call that. I am using declarative services and am running in 
an issue with publishing my service; here is my component.xml for my 
service:

<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0"; 
enable="true" immediate="true" name="ecf.test.one.host">
<implementation class="ecf.test.one.EchoServiceImp"/>
<property name="service.exported.interfaces" type="String" value="*"/>
<property name="service.exported.configs" type="String" 
value="ecf.generic.server"/>
<property name="org.eclipse.ecf.containerFactoryArgs" type="String" 
value="ecftcp://localhost:3001/server"/>
<service>
<provide interface="ecf.test.one.echoservice.EchoService"/>
</service>
<reference cardinality="1..1" 
interface="org.eclipse.ecf.core.IContainerFactory" 
name="IContainerFactory" policy="static"/>
</scr:component>

and when I start the framework, I get the following exception:

I can't figure out what I am missing. Any help is greatly appreciated to 
get me going.

Thanks,
