Hi Rajith, 'Task' is one of the artifact types in ESB. So similar to other artifact types like proxy services, sequences, etc. task has it's own synapse configuration.
Even you write a custom task and deploy the jar into libs directory, you need to create a task configuration to trigger it. Following is a sample task configuration. <task xmlns="http://ws.apache.org/ns/synapse"; name="inQ.taskTrigger" class="org.wso2.sample.SampleTask1" group="synapse.simple.quartz"> <trigger interval="10"/> <property xmlns:task="http://www.wso2.org/products/wso2commons/tasks"; name="Property1" value="value1"/> </task> You can pass parameters for your custom task as a property. I don't have a clear idea of what you are implementing, but I feel like you can implement this scenario using the existing functionality of ESB without writing a custom task. Thanks.
