ADF Calling Bounded Task Flow Using URL

Task Flow can be called through a URL. Both calling and called Task flows should use pages not page fragments(.jsff).Task flow reference and remote-app-url property combined generate URL of remote task flow URL.
Create  an ADF application and create a bounded task flow in it.

Note the URL invoke property is set to url-invoke-allowed in the task flow.

For calling bounded task flow using URL we can add a context parameter in web.xml for the URL.We can access the URL using #{initParam.remoteURL}

The url reference in the task flow

Though it shows an error message in the task flow diagram ,it works.
