Thanks Peter, I have uploaded 3 bundles to github and it is available in the below location. https://github.com/bharathkumara/river-osgi
It is eclipse workspace and we need bndtools eclipse plugin to run/debug it. 1. org.apache.river - River classes as system fragment bundle 2. org.apache.river.bootstrap - Contains code to start code server, export local osgi services(Remote) and publish it to network, listen for river services in the network and utilities. 3. org.apache.river.lookup - Lookup service as osgi bundle. Using these 3 osgi bundles, I am able to start reggie and clients can register services and lookup using service templates. I'll post example services later. We can use lookup.bndrun to test the lookup service. Steps to follow 1. Install Eclipse and Bndtools plugin 2. Import these 4 projects into eclipse 3. open the file lookup.bndrun which is located in org.apache.river.lookup project 4. Run/ debug it and it will open the gogo shell in console view. 5. I have written ad-hoc gogo shell command to start/stop the lookup service start the lookup using the below command lookup start stop the lookup using the below command lookup stop Get the running status of the lookup service lookup 6. We can use registrars command to list available lookup services in network registrars Please let me know your feedback.
