Hello, I have downloaded sling 8 from https://github.com/apache/sling and using the launchpad jar file I have installed the distribution bundles api, core, sample and dependencies in the author instance running at 8080 and also at the publish instance running at port 8090.
I want to test the forward distribution use case, described at contrib/extensions/distribution/README.md. I am running into UnsupportedOperationException and I need help on how to fix this issue please? Based on the information available in the README.md, I am trying to configure an agent on the author instance using POSTMAN from Chrome browser and I have specified admin/admin as authorization details. I can verify GET on http://localhost:8080/libs/sling/distribution/services/agents.json returns {"sling:resourceType":"sling/distribution/service/agent/list","items":[]} I interpret this to mean there no agents to start with. When I do POST at http://localhost:8080/libs/sling/distribution/services/agents Body is: { "jcr:primaryType": "sling:OsgiConfig", "name": "publish", "serviceName" : "distributionService", "requestAuthorizationStrategy.target" : "(name=privilegeRead)", "packageBuilder.target": "(name=vlt)", "transportSecretProvider.target" : "(name=publishAdmin)", "packageImporter.endpoints": [ "http://localhost:4503/libs/sling/distribution/services/importers/default"; ] } The response is: Content modified /libs/sling/distribution/services/agents Status 200 Message OK Location /libs/sling/distribution/services/agents Parent Location /libs/sling/distribution/services Path /libs/sling/distribution/services/agents Referer ChangeLog <pre></pre> Modified Resource Parent of Modified Resource I am assuming http://localhost:8090/libs/sling/distribution/services/importers/default must work and in the body importer endpoint must be changed. I still need to configure the importer on publish instance correctly. However, GET http://localhost:8080/libs/sling/distribution/services/agents.json still returns {"sling:resourceType":"sling/distribution/service/agent/list","items":[]} I was expecting to see the publish agent that was added successfully by the previous Post. Why the agent is not listed by the Get operation? >From access.log 0:0:0:0:0:0:0:1 - admin 30/Sep/2015:08:58:34 -0700 "POST /libs/sling/distribution/services/agents HTTP/1.1" 200 1490 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36" 0:0:0:0:0:0:0:1 - admin 30/Sep/2015:09:03:47 -0700 "GET /libs/sling/distribution/services/agents.json HTTP/1.1" 200 73 "-" "Mozilla/5.0 (Macintosh; Intel Mac OS X 10_10_5) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/45.0.2454.99 Safari/537.36" There are no errors in error.log When I do POST http://localhost:8080/libs/sling/distribution/services/agents/publish?action=ADD&path=/content the response is: Error while processing /libs/sling/distribution/services/agents/publish Status 500 Message org.apache.sling.api.SlingException: Exception during response processing.
