In Jdeveloper 11.1.1.7 there is no option to create ADF Skin declaratively
In order to apply skin we have to create a simple CSS file and then configure application to use this CSS file as skin. Jdeveloper doesn’t do this for us clip_image003we have to do it manually
So first step is to enable Skin Selectors for ADF Faces, Without enabling this CSS editor doesn’t show ADF Faces component tags
CSS files by default supports HTML tags  only
Go to Tools > Preferences > CSS Editor and set CSS level to level 3 and check the box to support ADF Faces Components

Now create a CSS file –
Right Click on View Controller project > Select New > Web Tier > HTML > CSS File

Provide a name for CSS file and click OK. Read the complete article here.

JDev 12.2.1: Remote Task Flows in Action by Timo Hahn

clip_image001The 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 is really simple as it consists of only one page and one task flow which shows the departments and its employees of the HR DB schema. Read the complete article here.

JDeveloper Debugging Tips (Watchpoints & Beep) by Richard Olrichs

In a previous blog post I talked about scoping breakpoints for debugging purposes, next to scoping breakpoints JDeveloper has more interesting debugging features to offer.

I created a simple example to show both the watchpoint as well as the beep functionality. To illustrate this, I created a page with an inputText and a button, both bound to a backingBean.

Now imagine that I want to halt execution everytime the bean field value changes. I can simply right-click the field and choose ‘Toggle Watchpoint’:

JDeveloper 12.1.3: Use Default Activity Instead of the Deprecated Invoke Action by Timo Hahn

Posted: December 1, 2014 in JDeveloper & ADF
Tags: , , , , , , ,

clip_image001Since JDeveloper 12.1.3 the invoke action used in earlier version has been deprecated. Users still using the old invoke action to load data on page load should migrate their code to using the default activity in a bounded task flow instead. This article describes how to use the executeWithParams method as a default activity in a bounded task flow (btf) to load data to be shown in a region. For this we implement a common

Use Case:
in a text field the user enters a string which should be used to look-up data in the DB and show the data as a table in a region.
For this we use the HR schema and build a look-up for locations after the name of the city of the location. In a page the user can insert the name or part of a cities name into a text field. This input is send as parameter to a bounded task flow. The default activity of the btf calls a method in the view object which uses a view criteria to search for cities starting with the given input data. In a second implementation the same technique is used but a where clause is used in the VO and the VO is called with executeWithParams. The result of the search is displayed as a table in a region.

Implementation

Model Project:
We start by creating a new ‘Fusion Web Application’ and creating a model project of the HR DB schema. Here we only use the location table for which we create entity object and view object.
Now we create the view criteria which we use to find locations by part of the city name.

Next step is to create the java class for the view object including the method to safely access the created bind variable. In the class we add a method to apply the created view criteria which we expose in the client interface well as the methods to access bind variables. Read the complete article here.
