JDev 12.2.1: Remote Task Flows in Action

JDev & ADF Goodies

The new JDeveloper version 12.2.1 is just out and has a lot of new features to investigate. In this post we see how remote task flows work. Yes, they are finally here and they are working. At least if you install a patch available from support.oracle.com.
The downloadable version on JDev 12.2.1 has a small bug which prevents you from running remote task flows (refer to https://community.oracle.com/thread/3816032). Support and the dev team quickly delivered a patch for this. To get the patch, open a service request and ask for a patch for bug 22132843.

Let’s start. We need two applications to show how remote task flows are implmented. One is the remote task flow producer, one consumes the remote task flow. An application can be both, producer and consumer. For this sample we keep it simple and define one app as producer and one as consumer.

Producer Application
This application…

JDeveloper: Navigation after Return from Bounded Task Flow

JDev & ADF Goodies

A question on the OTN JDeveloper and ADF ‘Space’ asked for a sample and/or tutorial on how to navigate after a bounded task flow, based on pages, returns from its work.
I setup a sample application to show how this works. The application is built using JDeveloper 11.1.1.7.0 and uses the HR DB schema. The sample can be loaded using the link provided at the end of the post.
Before we start let’s take a look at the running application:

Now that we have seen how the application works let’s check out how it’s implemented.

We start with an unbounded task flow (adfc-config.xml) which look like
Unbounded Task Flow: adfc-config.xml
We see that the application is built from two pages, a ‘Start’ page and an ‘End’ page. The ‘Start’ page can call a bounded task flow employee-btf. The start page holds one button ‘Start’ which calls the bounded task flow…
