Hi Imesh, I deployed application and deployment policy. Instances got started up successfully. Now I want to terminate the instances.
I tried undeploying as below. *curl -X DELETE -H "Content-Type: application/json" -d@'json/dep_single_group.json' -k -v -u admin:admin https://54.151.228.132:9443/api/applications/app_cartridge_v1/undeploy <https://54.151.228.132:9443/api/applications/app_cartridge_v1/undeploy>* It resulted in below warning. TID: [0] [STRATOS] [2014-12-18 13:43:48,324] WARN {org.apache.stratos.autoscaler.applications.topic.ApplicationBuilder} - Application has been found in the ApplicationsTopology: [application-id] app_cartridge_v1, Please unDeploy the Application Policy before deleting the Application definition. Then I tried undeploying application which completed successfully. *curl -X DELETE -H "Content-Type: application/json" -d@'json/dep_single_group.json' -k -v -u admin:admin https://54.151.228.132:9443/api/applications/app_cartridge_v1/ <https://54.151.228.132:9443/api/applications/app_cartridge_v1/>* TID: [0] [STRATOS] [2014-12-18 13:43:36,273] INFO {org.apache.stratos.autoscaler.api.AutoScalerServiceImpl} - Application deleted successfully: [application-id] Then I tried undeployed again which resulted in following error. I think application deletion causes the NPE below. *curl -X DELETE -H "Content-Type: application/json" -d@'json/dep_single_group.json' -k -v -u admin:admin https://54.151.228.132:9443/api/applications/app_cartridge_v1/undeploy <https://54.151.228.132:9443/api/applications/app_cartridge_v1/undeploy>* TID: [0] [STRATOS] [2014-12-18 13:43:48,325] ERROR {org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver} - Exception occurred while trying to invoke service method undeployApplication java.lang.NullPointerException at org.apache.stratos.autoscaler.api.AutoScalerServiceImpl.undeployApplication(AutoScalerServiceImpl.java:249) at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.apache.axis2.rpc.receivers.RPCUtil.invokeServiceClass(RPCUtil.java:212) at org.apache.axis2.rpc.receivers.RPCInOnlyMessageReceiver.invokeBusinessLogic(RPCInOnlyMessageReceiver.java:66) at org.apache.axis2.receivers.AbstractMessageReceiver.receive(AbstractMessageReceiver.java:110) at org.apache.axis2.engine.AxisEngine.receive(AxisEngine.java:180) at org.apache.axis2.transport.http.HTTPTransportUtils.processHTTPPostRequest(HTTPTransportUtils.java:172) at org.apache.axis2.transport.http.AxisServlet.doPost(AxisServlet.java:146) at org.wso2.carbon.core.transports.CarbonServlet.doPost(CarbonServlet.java:231) at javax.servlet.http.HttpServlet.service(HttpServlet.java:755) at javax.servlet.http.HttpServlet.service(HttpServlet.java:848) at org.eclipse.equinox.http.servlet.internal.ServletRegistration.service(ServletRegistration.java:61) at org.eclipse.equinox.http.servlet.internal.ProxyServlet.processAlias(ProxyServlet.java:128) at org.eclipse.equinox.http.servlet.internal.ProxyServlet.service(ProxyServlet.java:68) at javax.servlet.http.HttpServlet.service(HttpServlet.java:848) at org.wso2.carbon.tomcat.ext.servlet.DelegationServlet.service(DelegationServlet.java:68) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:305) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.wso2.carbon.tomcat.ext.filter.CharacterSetFilter.doFilter(CharacterSetFilter.java:61) at org.apache.catalina.core.ApplicationFilterChain.internalDoFilter(ApplicationFilterChain.java:243) at org.apache.catalina.core.ApplicationFilterChain.doFilter(ApplicationFilterChain.java:210) at org.apache.catalina.core.StandardWrapperValve.invoke(StandardWrapperValve.java:222) at org.apache.catalina.core.StandardContextValve.invoke(StandardContextValve.java:123) at org.apache.catalina.authenticator.AuthenticatorBase.invoke(AuthenticatorBase.java:472) at org.apache.catalina.core.StandardHostValve.invoke(StandardHostValve.java:171) at org.apache.catalina.valves.ErrorReportValve.invoke(ErrorReportValve.java:99) at org.wso2.carbon.tomcat.ext.valves.CompositeValve.continueInvocation(CompositeValve.java:178) at org.wso2.carbon.tomcat.ext.valves.CarbonTomcatValve$1.invoke(CarbonTomcatValve.java:47) at org.wso2.carbon.webapp.mgt.TenantLazyLoaderValve.invoke(TenantLazyLoaderValve.java:56) at org.wso2.carbon.tomcat.ext.valves.TomcatValveContainer.invokeValves(TomcatValveContainer.java:47) at org.wso2.carbon.tomcat.ext.valves.CompositeValve.invoke(CompositeValve.java:141) at org.wso2.carbon.tomcat.ext.valves.CarbonStuckThreadDetectionValve.invoke(CarbonStuckThreadDetectionValve.java:156) at org.apache.catalina.valves.AccessLogValve.invoke(AccessLogValve.java:936) at org.wso2.carbon.tomcat.ext.valves.CarbonContextCreatorValve.invoke(CarbonContextCreatorValve.java:52) at org.apache.catalina.core.StandardEngineValve.invoke(StandardEngineValve.java:118) at org.apache.catalina.connector.CoyoteAdapter.service(CoyoteAdapter.java:407) at org.apache.coyote.http11.AbstractHttp11Processor.process(AbstractHttp11Processor.java:1004) at org.apache.coyote.AbstractProtocol$AbstractConnectionHandler.process(AbstractProtocol.java:589) at org.apache.tomcat.util.net.NioEndpoint$SocketProcessor.run(NioEndpoint.java:1653) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1145) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:615) at java.lang.Thread.run(Thread.java:744) TID: [0] [STRATOS] [2014-12-18 13:43:48,326] ERROR {org.apache.axis2.receivers.AbstractMessageReceiver} - org.apache.axis2.AxisFault -- Udara Liyanage Software Engineer WSO2, Inc.: http://wso2.com lean. enterprise. middleware web: http://udaraliyanage.wordpress.com phone: +94 71 443 6897
