While debugging found that task manager is not initialize. This is due to outdated configurations. The EIP sample should be updated with following configuration changes.
1. add <taskManager provider= "org.wso2.carbon.mediation.ntask.NTaskTaskManager"/> 2. class should be org.apache.synapse.message.processor.*impl* .forwarder.ScheduledMessageForwardingProcessor 3. target.endpoint parameter is missing in messageProcessor configurations.
