I tried to debug the issue, Controller throws an illegal state exception at uncheckedInvoke(final RpcService rpcService, final CompositeNode domInput) method inside BindingIndependentConnector.java at line 875. It tries to invoke mappingService.dataObjectFromDataDom(inputClass.get(), domInput), which calls RuntimeMappingModule.java's dataObjectFromDataDom method.</p> <p>Above method calls YangTool's RunTimeGeneratedMappingServiceImpl.java class</p> <p>Exception Stack trace is </p> <p>2014-05-14 14:48:15 PDT [org.apache.catalina.core.ContainerBase.<span class="error">&#91;Catalina&#93;</span>.<span class="error">&#91;localhost&#93;</span>.<span class="error">&#91;/restconf&#93;</span>.<span class="error">&#91;JAXRSRestconf&#93;</span>] SEVERE org.apache.catalina.core.StandardWrapperValve invoke Servlet.service() for servlet <span class="error">&#91;JAXRSRestconf&#93;</span> in context with path <span class="error">&#91;/restconf&#93;</span> threw exception <span class="error">&#91;java.util.concurrent.ExecutionException: java.lang.IllegalStateException: Failed to create data object&#93;</span> with root cause<br/> java.lang.NullPointerException<br/> at org.opendaylight.yangtools.yang.common.QName.&lt;init&gt;(QName.java:140)<br/> at org.opendaylight.yangtools.yang.common.QName.create(QName.java:279)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.BindingSchemaContextUtils.findDataNodeContainer(BindingSchemaContextUtils.java:61)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.LazyGeneratedCodecRegistry$LocationAwareDispatchCodec.adaptForPath(LazyGeneratedCodecRegistry.java:689)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.LazyGeneratedCodecRegistry$AugmentableDispatchCodec.deserialize(LazyGeneratedCodecRegistry.java:1086)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.LazyGeneratedCodecRegistry$AugmentableDispatchCodec.deserialize(LazyGeneratedCodecRegistry.java:1040)<br/> at org.opendaylight.yang.gen.v1.opendaylight.sample.rev140407.saveentry.input.EntryField$Broker$Codec$DOM.fromDomStatic(EntryField$Broker$Codec$DOM.java)<br/> at org.opendaylight.yang.gen.v1.opendaylight.sample.rev140407.SaveEntryInput$Broker$Codec$DOM.fromDomStatic(SaveEntryInput$Broker$Codec$DOM.java)<br/> at org.opendaylight.yang.gen.v1.opendaylight.sample.rev140407.SaveEntryInput$Broker$Codec$DOM.deserialize(SaveEntryInput$Broker$Codec$DOM.java)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.LazyGeneratedCodecRegistry$DataContainerCodecImpl.deserialize(LazyGeneratedCodecRegistry.java:624)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.RuntimeGeneratedMappingServiceImpl.dataObjectFromDataDom(RuntimeGeneratedMappingServiceImpl.java:312)<br/> at org.opendaylight.yangtools.sal.binding.generator.impl.RuntimeGeneratedMappingServiceImpl.dataObjectFromDataDom(RuntimeGeneratedMappingServiceImpl.java:413)<br/> at org.opendaylight.controller.config.yang.md.sal.binding.impl.RuntimeMappingModule$RuntimeGeneratedMappingServiceProxy.dataObjectFromDataDom(RuntimeMappingModule.java:162)<br/> at org.opendaylight.controller.sal.binding.impl.connect.dom.BindingIndependentConnector$NoOutputInvocationStrategy.uncheckedInvoke(BindingIndependentConnector.java:876)<br/> at org.opendaylight.controller.sal.binding.impl.connect.dom.BindingIndependentConnector$RpcInvocationStrategy.invokeOn(BindingIndependentConnector.java:781)</p> <p>Operating System: Mac OS<br/> Platform: PC</p> CONTROLLER-473

Invoking RPC from RESTConf Fails after new data store changes

Bug Resolved Done Tony Tkacik Harman Singh Wed, 14 May 2014 22:16:46 +0000 Mon, 19 May 2014 17:59:51 +0000 Mon, 19 May 2014 17:59:51 +0000 0.4.0 mdsal 0 2 <p>The regression you are facing is not related to data store.</p> <p>From stack-trace it is obvious that you are trying to send / use augmented RPC,<br/> could you provide more information about your model / which RPC you were trying to invoke?.</p> <p>I have attached the zip file for your testing. Here are the steps you need to follow - </p> <p>Unzip the attached file. <br/> Go to directory model/target and copy mdsalApp-model-1.0.0.jar file to plugins folder of your controller distribution. This will load yang file in controller. <br/> Go to directory provider/target and copy mdsalApp-provider-1.0.0.jar to controller distribution’s plugin folder. Provider has implementation of the RPC which fails from RESTConf.<br/> Do the above mentioned similar steps for consumer, RPC call works fine from consumer. <br/> Go to directory web/target and copy mdsalApp-web-1.0.0.jar to controller distribution’s plugin folder. Web use RESTConf to call RPC. Once copied, you can try to access using <a href="http://localhost:8080/controller/web/mdsalApp/view" class="external-link" target="_blank" rel="nofollow noopener">http://localhost:8080/controller/web/mdsalApp/view</a> . You will see Add entry button on the UI. Click on Add Entry and fill title and description and press save button, This save button calls the RPC via REStConf and it fails. You can put debug points in controller to see point of failure.<br/> Hope above information helps, Let me know if you need any further details.</p> <p>Attachment mdsalApp.zip has been added with description: sample app to test RPC via REStConf</p> Development External issue ID 1011 External issue URL Rank 0|i02km7:
