Hi Ruchira/Madhuka, Any idea why does MSTaskAdmin tries to delete the admin/RESTSample during a server restart? This fails with a NPE while trying to undeploy the given service.
[1] https://wso2.org/jira/browse/WSAS-1550 NPE was observed when starting the worker first time in windows environment (error-1) and after restarting the server error-2 popups because of error-1 =============================== error -1 [2013-08-21 12:14:25,141] ERROR {org.wso2.carbon.mashup.javascript.hostobjects.system.MSTaskAdmin} - java.lang.NullPointerException at org.wso2.carbon.mashup.javascript.hostobjects.system.MSTaskAdmin.deleteTask(MSTaskAdmin.java:110) at org.wso2.carbon.mashup.jsservices.deployer.JSDeployer.undeploy(JSDeployer.java:271) at org.apache.axis2.deployment.DeploymentEngine.unDeploy(DeploymentEngine.java:909) at org.apache.axis2.deployment.repository.util.WSInfoList.update(WSInfoList.java:143) at org.apache.axis2.deployment.RepositoryListener.update(RepositoryListener.java:377) at org.apache.axis2.deployment.RepositoryListener.checkServices(RepositoryListener.java:254) at org.apache.axis2.deployment.RepositoryListener.startListener(RepositoryListener.java:371) at org.apache.axis2.deployment.scheduler.SchedulerTask.checkRepository(SchedulerTask.java:59) at org.apache.axis2.deployment.scheduler.SchedulerTask.run(SchedulerTask.java:67) at org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.runAxisDeployment(CarbonDeploymentSchedulerTask.java:65) at org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.run(CarbonDeploymentSchedulerTask.java:110) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:204) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) [2013-08-21 12:14:25,148] ERROR {org.wso2.carbon.mashup.jsservices.deployer.JSDeployer} - Unable to delete job : null org.apache.axis2.AxisFault: Error deleting task: admin/RESTSample at org.wso2.carbon.mashup.javascript.hostobjects.system.MSTaskAdmin.deleteTask(MSTaskAdmin.java:118) at org.wso2.carbon.mashup.jsservices.deployer.JSDeployer.undeploy(JSDeployer.java:271) at org.apache.axis2.deployment.DeploymentEngine.unDeploy(DeploymentEngine.java:909) at org.apache.axis2.deployment.repository.util.WSInfoList.update(WSInfoList.java:143) at org.apache.axis2.deployment.RepositoryListener.update(RepositoryListener.java:377) at org.apache.axis2.deployment.RepositoryListener.checkServices(RepositoryListener.java:254) at org.apache.axis2.deployment.RepositoryListener.startListener(RepositoryListener.java:371) at org.apache.axis2.deployment.scheduler.SchedulerTask.checkRepository(SchedulerTask.java:59) at org.apache.axis2.deployment.scheduler.SchedulerTask.run(SchedulerTask.java:67) at org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.runAxisDeployment(CarbonDeploymentSchedulerTask.java:65) at org.wso2.carbon.core.deployment.CarbonDeploymentSchedulerTask.run(CarbonDeploymentSchedulerTask.java:110) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:441) at java.util.concurrent.FutureTask$Sync.innerRunAndReset(FutureTask.java:317) at java.util.concurrent.FutureTask.runAndReset(FutureTask.java:150) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.access$101(ScheduledThreadPoolExecutor.java:98) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.runPeriodic(ScheduledThreadPoolExecutor.java:180) at java.util.concurrent.ScheduledThreadPoolExecutor$ScheduledFutureTask.run(ScheduledThreadPoolExecutor.java:204) at java.util.concurrent.ThreadPoolExecutor$Worker.runTask(ThreadPoolExecutor.java:886) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:908) at java.lang.Thread.run(Thread.java:662) Caused by: java.lang.NullPointerException at org.wso2.carbon.mashup.javascript.hostobjects.system.MSTaskAdmin.deleteTask(MSTaskAdmin.java:110) ... 19 more error 2 [2013-08-21 12:23:54,327] ERROR {org.wso2.carbon.mashup.jsservices.deployer.JSDeployer} - The service RESTSample.js is not valid. org.apache.axis2.AxisFault: Two services cannot have same name.
