I followed the toaster example exactly ( for the first section, with out RPC) and compiled. The yang model generated the required java files also.

The TestProviderModule::createInstance() is modified to create the AutoclosebaleTest also.

Created a file 04-test-sample.xml in initial for loading the service with the <capability> also as like toaster example.</capability>

While loading the server After loading the ToasterService. Kitchen Service and finally when it loads the TestService, an error was thrown.

capabilities=[urn:opendaylight:params:xml:ns:yang:controller:config:test-provider:impl?module=test-provider-impl&revision=2014-05-22]}. Expected but not found: [urn:opendaylight:params:xml:ns:yang:controller:config:test-provider:impl?module=test-provider-impl&revision=2014-05-22] at org.opendaylight.controller.netconf.persist.impl.ConfigPusher.getOperationService( ~[na:na]

I tried to debug and the exception was thrown from NetconfOperationService getOperationService(..) for my test urn.

NetconfOperationServiceImpl.setupCapabilities( ..) doesn't have my test urn. it got toaster and other classes. { .. yangstoreSnapShot doent have my test module. Set<module> modules = yangStoreSnapshot.getModules(); ..}</module>

Am I missing anything. Any help appreciated.

schemaContext.getModules() doesnt have the test module.

This sounds familiar. I think it's because your test-provider-impl yang is missing at run time. In your pom, for yang-maven-plugin, did you specify the CodeGeneratorImpl in addition to the JXMCodeGenerator? The former is what generates the $YangModelBindingProvider and $YangModuleInfoImpl that are scraped at run time to locate the yang file.

Yes I did. <codegenerators> <generator> <codegeneratorclass>org.opendaylight.controller.config.yangjmxgenerator.plugin.JMXGenerator</codegeneratorclass> <outputbasedir>${jmxGeneratorPath}</outputbasedir> <additionalconfiguration> <namespacetopackage1>urn:opendaylight:params:xml:ns:yang:controller==org.opendaylight.controller.config.yang</namespacetopackage1> </additionalconfiguration> </generator> <generator> <codegeneratorclass>org.opendaylight.yangtools.maven.sal.api.gen.plugin.CodeGeneratorImpl</codegeneratorclass> <outputbasedir>${salGeneratorPath}</outputbasedir> </generator> </codegenerators>

Hi Anu, could you check if you exposed the module instance as service? E.g. toaster exposes provider's module as service:

           <services xmlns="urn:opendaylight:params:xml:ns:yang:controller:config">
                    <type xmlns:kitchen="urn:opendaylight:params:xml:ns:yang:controller:config:kitchen-service:impl">

Thanks for the input. I am not using the module instance as a service. This is my 04-test-sample <snapshot> <configuration> <data xmlns="urn:ietf:params:xml:ns:netconf:base:1.0"> <modules xmlns="urn:opendaylight:params:xml:ns:yang:controller:config"> <module> <type xmlns:test="urn:opendaylight:params:xml:ns:yang:controller:config:test-provider:impl"> test:test-provider-impl </type> <name>test-provider-impl</name> <data-broker> <type xmlns:binding="urn:opendaylight:params:xml:ns:yang:controller:md:sal:binding">binding:binding-data-broker</type> <name>binding-data-broker</name> </data-broker> </module> </modules> </data> </configuration> <required-capabilities> <capability>urn:opendaylight:params:xml:ns:yang:controller:config:test-provider:impl?module=test-provider-impl&revision=2014-05-22</capability> </required-capabilities>

I am exactly going through the same issue and I have exposed the module instance as service as per Michal Rehak's advice. Like Anu, I was following the step by step procedure, and my provider was ( toaster-provider-2 ). Even after exposing the module instance the binding fails as it cannot find the required capability.

Root cause is NetconfOperationServiceImpl::yangstoreSnapShot doent have the module. Set<module> modules = yangStoreSnapshot.getModules(); ..} Not sure how to find / locate the module. Looks like some path issue.

The jar file was not there in ~/controller/opendaylight/distribution/opendaylight/target/distribution.opendaylight-osgipackage/opendaylight/plugins

sample-test-provider-1.1-SNAPSHOT.jar sample-test-1.1-SNAPSHOT.jar

I manually copied both my jars to this location and restarted controller.
