A task in WSO2 ESB allows you to run a piece of code triggered by a timer. WSO2 ESB provides a default task implementation, which you can use to inject a message to the ESB at a scheduled interval. To activate the built-in task, you have to add it to the Tasks list.
For information on working with tasks via the ESB tooling plug-in, see Working with Tasks via the ESB Tooling Plug-In.
For information on working with tasks via the Management Console, see Working with Tasks via the Management Console.
You can also write your own 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.
