The following diagram illustrates steps explain the process of creating and scheduling a custom task implementation.

The main steps while writing a task are as follows:

1. Write the Task class
2. Customize the task
3. Compile and bundle the task
4. Add the task to the WSO2 ESB class path
5. Configure and schedule the task in ESB Console

Step 1. Write the Task Class

In addition to the execute() method, it is also possible to make the class implement a JavaBean interface. The WSO2 ESB EI console can then be used to configure the properties of this JavaBean.

...

It is possible to pass values to a task at run time using property elements. When creating a Task object, WSO2 ESB EI will initialize the properties with the given values in the configuration file. For those properties given as XML elements, properties need to be defined within the Task class using the following format:

...

<property name="message">
<m0:getQuote xmlns:m0="http://services.samples/xsd">
<m0:request>
<m0:symbol>IBM</m0:symbol>
</m0:request>
</m0:getQuote>
</property>

After compiling and bundling the Task class, you need to add it to the WSO2 ESB EI class path. Place the JAR file to the repository/components/in the lib directory of the ESBWSO2 EI.

The Task class will be available for use from the next time you start WSO2 ESBEI.
