Oracle Mobile Cloud Service – External SOAP Service Connector

These days everything is about MCS/MAF. I'm also looking into this new area, but I'm trying to mix traditional ADF topics and new things. Who knows may be MCS/MAF is a new big thing and its good time to learn it. I was testing how it works to define my own custom SOAP connector to calculate currency conversion rate.

MCS developer portal allows to create and use new connector. Special wizard helps to complete this (more...)

Smart Combo Box LOV Based on Description Attribute

I had a question from blog reader for my previous post about smart Combo Box LOV - Smart Combo Box LOV with Filter. Reader was asking if it is possible to define Combo Box LOV on description rather than ID attribute. ADF BC out of the box allows to define LOV on readonly description attribute. I had a post about it - Defining the LOV on a Reference Attribute in Oracle ADF 11g. Today I (more...)

Master-Detail Pattern Implementation in ADF 12c Alta UI

ADF 12c and Alta UI change the way how we used to implement UI in ADF. Let's take a look into Master-Detail. Before Alta UI usual implementation for Master-Detail would be based on vertical layout with master on the top and details below. Alta UI provides different patterns like left-right, bottom-top for Master-Detail implementation - Oracle Alta UI Patterns. I would recommend to watch a demo from Shay Shmeltzer, he explains how to build left-right (more...)

Use Case of Auto Re-Execute Functionality in ADF BC

There are use cases, when data in DB is changed by background processes and we would like to display to the user latest data available. Very common implementation for this use case is to re-execute ADF iterator and VO each time when Task Flow or UI screen is accessed. Obviously this works, but performance would suffer - usually there is no need to re-fetch data each time, it must be re-fetched only when changes are (more...)

ADF BC Inline View Criteria for Hierarchical Search

ADF BC View Criteria allows to implement Inline View Criteria to execute hierarchal search. This is especially useful, when you have Master-Detail relationship and want to filter Master records, based on attribute value from Detail. Keep in mind, Inline View Criteria for hierarchical search would not work, if VO is based on custom SQL query. It works only with declarative VO's.

This is how View Criteria with detail search option looks like. If there is (more...)

ADF Alta UI 12c Responsive Layout Template

Alta UI in ADF 12c with combination of Tablet First template provides support for responsive UI. Often you would like to implement extra functionality for responsive layout, not available out of the box. I'm going to describe in this post, with very practical example, how this can be achieved. I will implement desktop and tablet view support with adjusted menu structure and header.

Tablet First template is shipped with ADF 12c and provides different facets (more...)

ADF 12c Dynamic Forms with ADF BC UI Categories

ADF 12c offers completely new way to implement UI forms. We can implement dynamic forms, based on static ADF BC components. Such approach could simplify form maintenance - when there will be changes in DB, developer would need to adjust only ADF BC EO/VO structure, without changing anything on UI. Bindings layers could determine data structure dynamically and dictate how to render UI blocks. ADF BC VO provides special metadata option to define how form (more...)

Red Samurai ADF Performance Audit Tool v 4.0 – Web Client Request Monitoring and Complete Query Analysis

I'm excited to announce, we have released a new version of our RSA audit tool. This is a major update after previous version released in February 2015 - Red Samurai ADF Performance Audit Tool v 3.4 - ADF Task Flow Statistics with Oracle DMS Servlet Integration.

It is already 3 years, since initial version - Red Samurai Performance Audit Tool - Runtime Diagnosis for ADF Applications. We are using it for many of our (more...)

Smart Combo Box LOV with Filter

Combo box LOV with filtering is simple, but effective feature not used often. You should rethink LOV design and apply combo box LOV with filtering where possible. Advantage of such LOV implementation is pretty clear - fast list items access, based on filter criteria. This will reduce number of times required to open LOV popup and improve performance of UI.

LOV VO should implement View Criteria, returning top items to be included into choice list. (more...)

Tabs Layout Support in Alta UI Tablet First Template

Tablet First Template in ADF 12c is ideal for both tablet and desktop. Combined with Alta UI layout, it offers light and responsive UI experience to the end users. I'm going to describe in this post, how to use ADF Faces Tabs with Alta UI in Table First template. I will show ADF regions are friendly with Web like UI design, without internal scrollbars in the page.

Page can be created referencing Tablet First template (more...)

Oracle Mobile Cloud Service First Hands-On Experience

Thanks to SOA Community and Jurgen Kress, I had a chance to play with Oracle MCS (Mobile Cloud Service). This new Oracle product is promoted with full force by Oracle PM team, there is dedicated Youtube channel with videos to watch and learn - Oracle Mobile Platform. Mobile Cloud Service offers mobile enterprise repository to organize and support your mobile development. Mobile backend services, security, connectors, storage and etc. can be defined and managed in (more...)

Using Shared AM to Cache and Display Table Data

This post is based on Steve Muench sample Nr. 156. In my personal opinion, ADF samples implemented by Steve Muench still remain one of the best source of examples and solutions for various ADF use cases. Sample Nr. 156 describes how to use Shared AM to display cached data in UI table. Typically Shared AM's are used to implement cached LOV's (session or application scope). But it could go beyond LOV, based on the use (more...)

Oracle Process Cloud Application Player

With Oracle Process Cloud you can forget these days when you was waiting long to deploy BPM process and test Human Task UI. No need to wait anymore, in Oracle Process Cloud you could use Application Player feature, this allows to run the process and test Human Task UI almost instantly.

To demonstrate Application Player functionality, I have implemented basic process of Data Entry for the Claim Handling:

This process is using Web Form in (more...)

Auto Refresh for ADF BC Cached LOV

You can configure auto refresh for ADF BC cached LOV and this works out of the box, no special coding is needed. My previous post describes how ADF BC session cached LOV behaves - ADF BC Session Cached LOV - Understanding Expire Time. Auto refresh can be configured for both application and session caching. One important thing - auto refresh doesn't work when ADF BC is configured with disconnected mode (ADF BC Tuning with (more...)

ADF BC Session Cached LOV – Understanding Expire Time

ADF BC offers LOV caching feature. There are two caching levels - application and session. With application level enabled, it makes LOV rows available for all users. On contrary for session level LOVs, data is cached for single session only. In this post I will focus on session level LOV's and I'm going to explain when cached data expires and is re-fetched.

You can configure caching level for LOV's in Model.jpx file, open AppModules (more...)

Oracle Process Cloud Service – SOAP Web Service Integration

Oracle Process Cloud ( allows to invoke SOAP services, along with REST services. You can define a library of SOAP services in Oracle Process Cloud application and use them within the process. This helps to integrate with business logic running on premise.

I have implemented regular SOAP service in ADF BC, just to test how it works to invoke it from Process Cloud:

SOAP service method accepts employee ID and checks (more...)

Oracle Process Cloud Service – Consuming ADF BC REST Service in Web Form

With the introduction of Oracle Process Cloud Service ( there is an option to run your business process in the cloud. You can implement very similar things as it is possible with BPM 12c in JDeveloper, but only in the cloud. There is no option to implement human task UI with ADF, it must be done with Web Forms (light UI forms implementation framework). This is disadvantage, as it will require (more...)

Intercepting Table Filter Query and Manipulating VO SQL Statement

I’m going to describe one non declarative use case. Imagine, if there is a table with filter functionality, you may want to intercept filter items and apply the same for another VO. This another VO should be based on the same DB table, so it could apply criteria items against the table.

Sample application -, implements a fragment with table component and a chart. Table component can be filtered, criteria is intercepted (more...)

Select One Choice with Select Items Tag

If you need to implement select one choice based on alternative data sources (not based on ADF BC) - you shouldn't use af:forEach inside af:selectOneChoice component. Don't get confused with af:forEach tag, this tag is supposed to generate multiple components and not to iterate over a collection of objects and render HTML for each item. There could be cases, when choice list data will come duplicated, with af:forEach tag applied. I would suggest to construct (more...)

How To Record ADF Client Side Request Performance Time

I had a blog post, where I have described how to monitor client side request performance time with Ajax tag (works in ADF 12c) - Monitoring PPR Request Time on ADF UI Client Side. There is effective way to propagate recorded statistics back to the server for history logging using WebSockets - WebSocket Integration with ADF for PPR Request Monitoring. This requires WebSockets integration into project, if project doesn't allow this - there is another (more...)
