A scheduled task in WSO2 Enterprise Integrator (WSO2 EI) allows you to run a piece of code triggered by a timer. The ESB profile of WSO2 EI provides a default scheduled task implementation, which you can use to inject a message to WSO2 EI at the ESB profile at a scheduled interval. To activate the built-in task, you have to add it to the Tasks list.
You can also write your own scheduled task by creating a custom Java class that implements the
org.apache.synapse.startup.Task interface. This interface defines a single method named
execute(). For example, you could create a task that will read a text file at a specified location and place orders for stocks that are given in the text file. For more information, see Writing Tasks.
