This document discusses integrating custom taskflows into Oracle WebCenter Portal. It outlines the overall development process, including developing taskflows in JDeveloper using web services or data sources, packaging them as a shared library WAR file, deploying the WAR to WebLogic Server, registering the library with the portal, adding the taskflows to the portal's resource catalog, and using them on portal pages. It also covers configuring datasources and web services in WebLogic Admin Console and Enterprise Manager to match the taskflow configuration.
