EIG:Install TimeService Tutorial into Apache Karaf

Introduction

See the Building your first OSGi Remote Services Tutorial to understand how to design and build this example TimeService.

To run the remote time service host example on Apache Karaf with ECF Remote Services, first install Install the ECF Remote Service SDK into Apache Karaf. Then use the command shell to set a debug system property

karaf@root()> system:property verboseRemoteServiceAdmin true

Then install the timeservice host example

karaf@root()> feature:install -v ecf.rs.examples.timeservice.host

Once complete, the install process should look like this

Optionally, before starting the TimeService host you can turn on some extra output by issuing this command into the Apache command shell

karaf@root()> system:property service.exported.configs ecf.generic.server

Then using the webconsole (or the command shell) start the bundle

ECF RS Example Timeservice Host (bundle symbolic id: com.mycorp.examples.timeservice.host)

This will produce output in the command shell (System.out) similar to the following, indicating that the service has been exported by RemoteServiceAdmin and the MyTimeService registered.

karaf@root()> Service Exported by RemoteServiceAdmin.  EndpointDescription Properties=ecf.endpoint.id=
ecftcp://localhost:3288/server, ecf.endpoint.id.ns=org.eclipse.ecf.core.identity.StringID, 
ecf.endpoint.ts=1394381999769, ecf.generic.server.hostname=localhost, ecf.generic.server.port=3288, 
ecf.rsvc.id=1, endpoint.framework.uuid=0a22aaf0-e110-4a89-ac62-edd97e44b2c1, 
endpoint.id=a7d3c846-5304-4e34-bf43-03224a4a138f, endpoint.package.version.com.mycorp.examples.timeservice=1.0.0,
endpoint.service.id=485, objectClass=Ljava.lang.String;@78d2df8c, remote.configs.supported=
[Ljava.lang.String;@6faf2576, remote.intents.supported=[Ljava.lang.String;@53c49f42, service.id=485,
service.imported=true, service.imported.configs=[Ljava.lang.String;@6faf2576}
MyTimeService host registered with registration=org.apache.felix.framework.ServiceRegistrationImpl@7a627ff2

For reference, this output is produced by the TimeService Examples Host activator class com.mycorp.examples.timeservice.host.Activator

The output above indicates that the TimeService has been exported and is ready for remote consumer access.
