When you are working with task portlet applications that run in My webMethods Server/Task Engine, best results are obtained by using the embedded Task Engine APIs as much as possible. These APIs are created when you create a task application portlet.

These APIs exist as Java classes in the package com.webmethods.caf.faces.data.task.impl. For more information, see the Javadoc pages for this package and its classes, available on the Empower Product Support Website.

In some cases, it is not possible to use these APIs (for example, from an application that is external to My webMethods Server, from a business process model, or from an IS service). In these instances, you can use the Task Engine APIs from the WmTaskClient package. For more information, see Working with the Task Engine APIs).
