[ecf-dev] Problem using multiple services from single server

[Peter Hermsdorf <peter.hermsdorf@xxxxxxxxx>]

Hi folks,

I’m trying to export and use multiple remote services from one server machine, which currently does not seem to work.

On Client side I’m using multiple EDEF Bundles(generated) to describe the services to discover. The xml is like this:

<?xml version="1.0" encoding="UTF-8"?>
<endpoint-descriptions xmlns="http://www.osgi.org/xmlns/rsa/v1.0.0">
  <endpoint-description>
    <property name="ecf.endpoint.id.ns" value-type="String" value="org.eclipse.ecf.core.identity.StringID"/>
    <property name="endpoint.id" value-type="String" value="ecftcp://peter-desktop:8889/Server"/>
    <property name="endpoint.package.version.com.godyo.service1.api" value-type="String" value="1.0.0"/>
    <property name="endpoint.service.id" value-type="Long" value="0"/>
    <property name="objectClass" value-type="String">
      <array>
        <value>com.godyo.service1.api.IService1</value>
      </array>
    </property>
    <property name="remote.configs.supported" value-type="String">
      <array>
        <value>ecf.generic.server</value>
      </array>
    </property>
    <property name="remote.intents.supported" value-type="String">
      <array>
        <value>passByValue</value>
        <value>exactlyOnce</value>
        <value>ordered</value>
      </array>
    </property>
    <property name="service.imported" value-type="String" value="true"/>
    <property name="service.imported.configs" value-type="String">
      <array>
        <value>ecf.generic.server</value>
      </array>
    </property>
  </endpoint-description>
</endpoint-descriptions>

The same for the second service with changed objectClass and packagename.

On server side I'm exporting the Services using a DS secription like this one:

<?xml version="1.0" encoding="UTF-8"?>
<scr:component xmlns:scr="http://www.osgi.org/xmlns/scr/v1.1.0" enabled="true" immediate="true" name="com.godyo.provider.service1">
   <implementation class="com.godyo.Service1Impl"/>
   <property name="service.exported.interfaces" type="String" value="*"/>
   <property name="service.exported.configs" type="String" value="ecf.generic.server"/>
   <property name="ecf.generic.server.port" type="String" value="8889"/>
   <service>
      <provide interface="com.godyo.service1.api.IService1"/>
   </service>
</scr:component>

the same for Service 2 with changed "name", "implementation class" and "provided interface" of course.

On server startup i get the following message in the console:

!ENTRY org.eclipse.ecf.osgi.services.remoteserviceadmin 4 0 2015-03-10 16:15:01.161
!MESSAGE org.eclipse.core.runtime.MultiStatus[plugin=org.eclipse.ecf.osgi.services.remoteserviceadmin;code=4;message=Advertise endpointDesription=ECFEndpointDescription[id=ecftcp://peter-desktop:8889/server;endpoint.service.id=2;frameworkid=20cbb433-38c7-0014-1758-9d831483e3d2].  Problem in unadvertise;severity4;exception=null;children=[Status ERROR: org.eclipse.ecf.osgi.services.remoteserviceadmin code=0 Advertise endpointDescription=ECFEndpointDescription[id=ecftcp://peter-desktop:8889/server;endpoint.service.id=2;frameworkid=20cbb433-38c7-0014-1758-9d831483e3d2].  Service Info is null.  Cannot publish endpointDescription=ECFEndpointDescription[id=ecftcp://peter-desktop:8889/server;endpoint.service.id=2;frameworkid=20cbb433-38c7-0014-1758-9d831483e3d2] null]]

When listing the "services" on the osgi server console i get:

{com.godyo.service1.api.IService1}={ecf.generic.server.port=8889, component.name=com.godyo.provider.service1, component.id=0, service.exported.configs=ecf.generic.server, service.exported.interfaces=*, service.id=48}
  Registered by bundle: com.godyo.p5.service1_4.1.1453.qualifier [12]
  Bundles using service:
        org.eclipse.ecf.osgi.services.remoteserviceadmin_3.0.0.v20131027-1505 [29]
{com.godyo.service1.api.IService2}={ecf.generic.server.port=8889, component.name=com.godyo.provider.service2, component.id=2, service.exported.configs=ecf.generic.server, service.exported.interfaces=*, service.id=66}
  Registered by bundle: com.godyo.p5.service2_4.1.1453.qualifier [24]
  Bundles using service:
    org.eclipse.ecf.osgi.services.remoteserviceadmin_3.0.0.v20131027-1505 [29]

On client side only one of the remote services gets registered (i think the last one/2nd ....)

Should this setup work this way or is there another approach needed to provide/consume multiple services?

I also tried using different values for ecf.generic.server.path (in the above axample "/server") for the two different services on client and server but also with no luck ...

My environment:
- ECF version 3.7 (i'm currently bound to eclipse indigo 3.7 RCP)
- generic provider


Any hints on a solution are very welcome!

Thanks, bye peter
