WSO2 DSS 3.5.0 - DataService Task Class error

I'm currently working on WSO2 DSS 3.5.0, trying to follow this example: https://itsmeisuru.wordpress.com/2013/11/29/wso2-dss-scheduled-task-example/

I've created the JAR file of a simple java class that implement "DataTask". It put this JAR in the repository DSS_HOME/repository/components/lib like it's said in step 2 of the example.

Then, when I create the schedule task like in the step 6. I have the following error in my server console:

INFO {org.quartz.core.JobRunShell} - Job TENANT_-1234_TYPE_DATA_SERVICE_TASK.ScheduleTest threw a JobExecutionException: org.quartz.JobExecutionException: Error in executing task: Error in initializing Data Task: sample.Test cannot be found by org.wso2.carbon.dataservices.task_4.3.4 [See nested exception: java.lang.RuntimeException: Error in initializing Data Task: sample.Test cannot be found by org.wso2.carbon.dataservices.task_4.3.4] at org.wso2.carbon.ntask.core.impl.TaskQuartzJobAdapter.execute(TaskQuartzJobAdapter.java:74) at org.quartz.core.JobRunShell.run(JobRunShell.java:213) at java.util.concurrent.Executors$RunnableAdapter.call(Executors.java:511) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1142) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:617) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.RuntimeException: Error in initializing Data Task: sample.Test cannot be found by org.wso2.carbon.dataservices.task_4.3.4 at org.wso2.carbon.dataservices.task.DSTaskExt.init(DSTaskExt.java:42) at org.wso2.carbon.ntask.core.impl.TaskQuartzJobAdapter.execute(TaskQuartzJobAdapter.java:66) ... 6 more Caused by: java.lang.ClassNotFoundException: sample.Test cannot be found by org.wso2.carbon.dataservices.task_4.3.4 at org.eclipse.osgi.internal.loader.BundleLoader.findClassInternal(BundleLoader.java:501) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:421) at org.eclipse.osgi.internal.loader.BundleLoader.findClass(BundleLoader.java:412) at org.eclipse.osgi.internal.baseadaptor.DefaultClassLoader.loadClass(DefaultClassLoader.java:107) at java.lang.ClassLoader.loadClass(ClassLoader.java:357) at java.lang.Class.forName0(Native Method) at java.lang.Class.forName(Class.java:264) at org.wso2.carbon.dataservices.task.DSTaskExt.init(DSTaskExt.java:36) ... 7 more

Note that my package name is "sample" and the name of my java class is "Test".

It looks like the scheduled task doesn't retrieve the class I indicate in the field "DataService Task Class".

Has anybody already had the same problem?

I also tried to used the JAR generated in the example as it's provided in the step 2. Then I follow the very same other steps. Finally I have the same problem:

[classpath] cannot be found by org.wso2.carbon.dataservices.task_4.3.4
