  • Get an Introduction to Oracle ADF - Online Anytime

    - by shay.shmeltzer
    Last year we started recording various sessions about advanced ADF topics (binding, security, skinning etc) and published them in the new Oracle ADF Insider page on OTN.These are the type of sessions we usually deliver in the Oracle Develop or ODTUG conferences. But now you can watch them whenever you need to better understand these topics.Now we are extending the series to also cover the basics of Oracle ADF.We just published three sessions that cover an overview of Oracle ADF, an introduction to Oracle ADF Business Components, and an overview of Oracle ADF Faces.So if you are starting out and need to quickly understand what ADF is all about, or if you just want to understand what does ADF offers these might be a good starting point.Check out the ADF Insider Basics Sessions here.

  • Passing Parameters Between Web-Services and JSF Pages

    - by shay.shmeltzer
    This is another quick demo that shows a common scenario that combines several demos I did in the past. The scenario – we have two web services, one returns a list of objects, the other allows us to update an object. We want to build a page flow where the first page shows us the list of objects, allows us to select one, and then we can edit that instance in the next page and call the second web service to update our data source. The demo shows: How to select a row and save the object value in a pageFlowScope. (using setPropertyListener). How to create a page that allows me to modify the value of the pageFlowScope object, and how to pass the object as a parameter to the second Web service. Check it out here:

  • Adaptive Layout for ADF Faces on Tablets

    - by Shay Shmeltzer
    In the 11.1.16 version of Oracle ADF we started adding specific features to the ADF Faces components so they'll work better on iPad tablets. In this entry I'm going to highlight some new capabilities that we have added to the 11.1.2.3 release. (note if you are still on the 11.1.1.* branch - you'll need to wait for 11.1.1.7 to get the features discussed here). The two key additions in the 11.1.2.3 version compared to the 11.1.1.6 features for iPad support include: pagination for tables and adaptive flow layout. The pagination for table is self explanatory, basically since iPad don't support scroll bars, we automatically switch the table component to render with a pagination toolbar that allow you to scroll set of records or directly jump to a specific set. See the image below. The adaptive flow layout takes a bit more explanation. On regular desktops the UI that you usually build for ADF Faces screens is going to use stretch layout - meaning that it stretches to fill the whole area of the browser window. If you resize the browser windoe, the ADF Faces page resizes with it. If your browser window is too small, scroll bars will appear to allow you to scroll to areas that are "hidden". However on an iPad, this is probably not the type of layout you want - you would rather have a flow layout that eliminates scroll bars and instead allows you to scroll down the page. Basically your want the page to be sized based on its content, rather then based on the browser window size. In ADF Faces terminology this can be done with the dimensionsFrom property set to "children". And here comes the tricky part, since in the past(and also today) when you create an ADF Faces page and add a stretchable component to it, the dimensionsFrom property is set to parent by default. This will be true to other layout components you'll add as well. At this point you might be wondering "Does this mean I'll need to go to each of the layout components in my page and modify the dimensionsFrom property value to be children?" ADF Faces to the rescue... To eliminate the need to do this tedious manual changes, we introduced a new web.xml parameter "oracle.adf.view.rich.geometry.DEFAULT_DIMENSIONS" You'll basically add the following to your web.xml <context-param>    <description>      This parameter controls the default value for component geometry on the page.      Supported values are:        legacy - component attributes use the default values as specified for the attributes                 in the tag documentation (default value)        auto   - component attributes use the correct default value given the value of their                 parent component. For example, with this setting, the panelStretchLayout                 will use "auto" as the default value for its "dimensionsFrom" attribute                 instead of "parent".    </description>    <param-name>oracle.adf.view.rich.geometry.DEFAULT_DIMENSIONS</param-name>    <param-value>auto</param-value>  </context-param> Once you set this parameter, you only need to set the dimensionsFrom attribute for the top level layout component on your page, and the rest of the components will adjust accordingly. One trick that you can use, and that is used in the demo below, is to have the dimensionsFrom property depend on the type of client that access your application. This way you can switch between stretch or flow layout based on the device accessing your application. For example I use the following in my page: <af:panelStretchLayout topHeight="70px" startWidth="0px" endWidth="0px"                                       dimensionsFrom="#{adfFacesContext.agent.capabilities['touchScreen'] eq 'none'  ? 'parent' : 'children' }"> Which results in a flow layout for iPads and a stretch layout for regular browsers. Check out the result in the below demo: &amp;lt;span id=&amp;quot;XinhaEditingPostion&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;

  • Do you have an address column somewhere in your database?

    - by shay.shmeltzer
    Do you have an address column somewhere in your database? If the answer is yes - then the Web seminar I'm going to run together with the guys from Navteq on May 26th, might be of interest to you. You see, we all have geographical related information in our database, but many of us don't actually use this to do any geographical type of operations/representation with it. Well once you attend the "Add Maps to Your Java Applications - the Easy Way" seminar this might change. In the seminar we'll give you a quick overview of the Spatial related capabilities of the Oracle DB, Middleware and tools. And a demo showing you how easy it is to actually get data to show up on a map in your application and to interact with it. So register today, and mark your calendar.

  • Deploying Oracle ADF Essentials Applications to Glassfish

    - by Shay Shmeltzer
    With the new Oracle ADF Essentials offering you can now deploy applications that leverage Oracle ADF on the open source Glassfish 3.1 server. Deployment is documented in the official JDeveloper and ADF documentation (here) but below is a summary of the steps and a video of the steps you'll need to take to get a basic Oracle ADF Essentials application to work on GlassFish. Note - to make starting/stopping GlassFish easier for my demo I used my GlassFish extension that you can get here. First we'll install some ADF Runtime libraries on GlassFish Download and install Glassfish (Note - if you also have an Oracle DB on the same machine, you'll want to switch GlassFish's HTTP port to something else instead of 8080). Download the Oracle ADF Essentials packaging - this will get you an adf_essentials.zip file. Copy the adf_essentials.zip to the lib directory of your Glassfish domain - on a default windows install this would be: C:\glassfish3\glassfish\domains\domain1\lib Go the the above lib directory and issue a unzip -j adf_essentials.zip This will extract the ADF libraries to the directory. Now you can start the Glassfish server. Now let's configure Glassfish to handle applications of the ADF type: Invoke the admin console of glassfish (http://localhost:4848) and log into your admin account. Go to Configurations->Server-config->JVM Settings and choose the JVM Options tab Add the following entries: -XX:MaxPermSize=512m (note this entry should already exist so just make sure it has a big enough value) -Doracle.mds.cache=simple While we are in the admin console, we can also define JDBC connections that will be used by our application. Go into Resources->JDBC->JDBC Connection Pools and click to create a New one Give it a name and choose the resource type to be javax.sql.XADataSource and choose Oracle as the Database Driver vendor. Click Next Scroll down to the Additional Properties section and start filling in the information for your database. The values for an Oracle XE will be (user=hr, databaseName = XE, Password=hr, ServerName=localhost, DriverType=thin, PortNumber=1521) Click Finish Click Ping to check your connection works. Now define a new JDBC Resource that will use the pool you just defined. In my example I called the resource jdbc/HRDS You will need this name to match the name in your Application Module connection configuraiton.Now you can re-start the Glassfish server for the changes to take effect. Get an ADF application going (you can use the regular Fusion Application template for this) Go into the project properties of your viewController project, under the deployment section click to edit the deployment profile that is defined there. Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. Go to Application -> Application Properties-> Deployment Go to Platform and choose Glassfish 3.1 from the drop down list. Click ok to go back to your project. This step will make sure that JDeveloper will autoamtically add the necessary ADF libraries to the EAR file that is being generated for deployment on Glassfish  Go to your Application->Deploy and deploy either to an EAR file or directly to a Glassfish server connection that you created. Things should just work, but if they don't then look up the server.log in the log directory and check out what error is in there. Here is a video demo of the various steps: Note - right now the deployment of an ADF application takes about 2 minutes on my machine we are hoping to be able to improve this timing in the future. People who are more familiar with Glassfish might want to explore using exploded directory deployment and see if they can get it to work.

  • ADF Faces Skin Editor - How to Work with It

    - by Shay Shmeltzer
    The ODTUG Kscop11 conference was a great success with lots of sessions about FMW running in a special track. I did several sessions and labs in the conference, and I thought it might be a good idea to at least give you a taste of what you might have missed. So here is most of what I demoed in my ADF Faces Skinning session (not all though - that session was 60 minutes long, and while everyone did end up going out of the building in the middle because of a fire drill for about 5 minutes, there was other things covered in the session as well). In the demo here you'll see how to generate new images and default color scheme, how to identify a component class with Firebug, how to skin a component, how to identify the global selector of a property, how to change fonts and how to change strings. By the way, for more on ADF Skinning you should also listen to the ADF Insider seminar that Frank Nimphius recorded on skinning, it will give you better understanding of the overall skinning process. P.S. in the demo I add an entry to the web.xml file which prevent ADF Faces from compressing the HTML that is generated. The entry is for org.apache.myfaces.trinidad.DISABLE_CONTENT_COMPRESSION  and I set it to true. This is very useful when you work on creating the skin, but don't forget to un-set it before you go production.

  • Calling Web Service with Complex Parameters in ADF Mobile

    - by Shay Shmeltzer
    Many of the SOAP based web services out there have parameters of specific object types - so not just simple String/int inputs. The ADF Web service data control makes it quite simple to interact with them. And this applies also in the case of ADF Mobile. Since there were several thread on OTN asking about this - I thought I'll do a quick demo to refresh people memory about how you pass these "complex" parameters to your Web service methods. By the way - this video is also relevant if you are not doing mobile development, you'll basically use the exact same process for building "regular web" ADF applications that access these types of Web services. One more thing you might want to do after you create the page is look at the binding tab to see the method call in there, and notice the parameters for it in the structure property. Go and look at their NDValue property to get the complete picture.

  • Passing Parameters to an ADF Page through the URL - Part 2.

    - by shay.shmeltzer
    I showed before how to pass a parameter on the URL when invoking a taskflow (where the taskflow starts with a method call and then a page). However in some simpler scenarios you don't actually need a full blown taskflow. Instead you can use page level parameters defined for your page in the adfc-config.xml file. So below is a demo of this technique. I'm also taking advantage of this video to show the concept of a view object level service method and how to invoke it from your page. P.S. You might wonder - why not just reference #{param.amount} as the value set for the method parameter? Why do I need to copy it into a viewScope parameter? The advantage of placing the value in the viewScope is that it is available even when the page went through several sumbits. For example if you switch the "partialSumbit" property of the "Next" button to false in the above example - the minute that you press the button to go to the next department - the param.amount value is gone. However the ViewScope is still there as long as you stay on this page.

  • Speed up ADF Mobile Deployment to Android with Keystore

    - by Shay Shmeltzer
    As you might have noticed from my latest ADF Mobile entries, I'm doing most of my ADF Mobile development on a windows machine and testing on an Android device. Unfortunately the Android/windows experience is not as fast as the iOS/Mac one. However, there is one thing I learned today that can make this a bit less painful in terms of the speed to deploy and test your application - and this is to use the "Release" mode when deploying your application instead of the "Debug" mode. To do this you'll first need to define a keystore, but as Joe from our Mobile team showed me today, this is quite easy. Here are the steps: Open a command line in your JDK bin directory (I just used the JDK that comes with the JDeveloper install). Issue the following command: keytool –genkey –v –keystore <Keystore Name>.keystore –alias <Alias Name> -keyalg RSA –keysize 2048 –validity 10000 Both keystore name and alias names are strings that you decide on. The keytool utility will then prompt you with various questions that you'll need to answer. Once this is done, the next step is to configure your JDeveloper preferences->ADF Mobile to add this keystore there under the release tab:  Then for your application specific deployment profile - switch the build mode from debug to release. The end result is a much smaller mobile application (for example from 60 to 21mb) and a much faster deployment cycle (for me it is about twice as fast as before).

  • Oracle OpenWorld / JavaOne Where I'll Be

    - by Shay Shmeltzer
    It's that time of the year again when San Francisco get flooded with Oracle and Java geeks for the annual OpenWorld and JavaOne conferences. Here are some of the places where you'll be able to find me: Sunday has a bunch of great ADF content in the ADF Enterprise Methodology Group track - I'm not sure if I'll make it there but I'm sure those who will will get some serious knowledge transfer. I'm starting Monday at the Keynote for Developers (10:45 in Salon 8 at the Marriott) - that's a great place for ADF developers to start the official week with an overview of what's new and upcoming in the world of development with ADF. While I'm not presenting this session - Chris Tonas who leads the development tools org will -  a demo that I built will be shown. So I'll be sitting in the audience crossing my fingers praying for the demo gods (and the wifi connection to work). My presentation part of the week starts on Monday at 12:15 at Moscone South room 306 where I'll be presenting "CON3004 - Understanding Oracle ADF and Its Role in Oracle Fusion"  . A basic introduction to ADF, it's architecture, development experience and how it integrates and works with the rest of the Fusion Middleware components.  After the session between 2-4 I'll be at the JDeveloper demo booth in Moscone South to answer any questions people might have. Then at 6:15 together with Grant we'll host BOF4492 - How to Get Started with Oracle ADF where we'll try and explain some of the learning paths and resources that are available for people who want to start learning ADF. This is a birds-of-a-feather so we'll also love to hear ideas from the audience about what paths they took and what things work or need improvment. Tuesday is relatively a quite day for me with a shift at the Oracle ADF Essentials pod at JavaOne from 1:30-3:30. There are several very good ADF architecture and best practices sessions on that day - so I'll try and hit those. Wednesday starts with another shift at the JDeveloper booth at JavaOne. Then at 4:30, instead of doing what all the ADF developers should do and heading over to the ADF meetup at the OTN Lounge, I'll be heading over to JavaOne for my CON3770 - Oracle JDeveloper and Oracle ADF: What’s New session. It's been a couple of years since the last time JDeveloper or ADF got any airtime at JavaOne - so it will be a great opportunity to show those in the Java community with open minds our approach to Java development. Now that ADF Essentials offers a free way to develop with ADF on GlassFish, I hope we'll be getting more people from the core Java camp interested in what we have to offer. Thursday is another relaxed day for me - who knows maybe I'll even be able to catch a session or two on that day. If you want to learn more about the ADF related sessions at OOW check out our full list here.

  • Building iPhone Interfaces for Oracle E-Business Suite

    - by Shay Shmeltzer
    Over on his blog Juan has been showing you how simple it is to develop a rich Web user interface with ADF accessing Oracle E-Business Suite data and even exposing it on an iPad. In this entry I'm starting from his sample application and I'm showing how easy it is to build an interface that will look great on an iPhone (or other mobile devices) using Oracle ADF Mobile Browser. For those of you who are just using ADF and never tried ADF Mobile Browser - you'll find that the development experience is quite familiar and similar to your normal Web application development. In the latest version of JDeveloper (11.1.2.1) which I'm usingin this demo we have a built-in skin that will give your application the native iOS look and feel. In the demo I achieve this by setting the styleclass of a tr:panelHeader component to af_m_toolbar to get this. For more on this styling read the doc. Check out this quick demo:

  • ADF Mobile - Update through Web Service (with ADF Business Components)

    - by Shay Shmeltzer
    In my previous blog entry I went over the basics of exposing ADF Business Components through service interfaces, and developing a simple ADF Mobile application that access and fetches data from those services. In this entry we'll dive a bit deeper  and address an update scenario through these web service interfaces. You can see the full demo video at the end of the post. In the first steps I show how to add an explicit method execution to fetch a specific record we want to update on the second page of a flow. For an update you'll be invoking a service method and passing the record you want to update as a parameter. As in many other Web services scenarios, we need to provide a complete object of specific type to the method. The ADF Web service data control helps you here by offering an object of this type that you can drag and drop into your page. The next step is to make sure to fill that object with the values you want to update. In the demo we do this through  coding in a backing bean that shows how to use the AdfmfJavaUtilities utility. The code gets the value from one field, gets a pointer to the parallel update field, and then copy from one to the other. At the end of the bean we manually execute the call to the update method on the Web service. Here is the demo: &amp;amp;amp;amp;&amp;lt;span id=&amp;quot;XinhaEditingPostion&amp;quot;&amp;gt;&amp;lt;/span&amp;gt;lt;span id=&amp;amp;amp;amp;quot;XinhaEditingPostion&amp;amp;amp;amp;quot;&amp;amp;amp;amp;gt;&amp;amp;amp;amp;lt;/span&amp;amp;amp;amp;gt; Here is the code used in the backing bean in the demo above. package a.mobile;import oracle.adfmf.amx.event.ActionEvent;import javax.el.MethodExpression;import javax.el.ValueExpression;import oracle.adfmf.amx.event.ActionEvent;import oracle.adfmf.framework.api.AdfmfJavaUtilities;import oracle.adfmf.framework.model.AdfELContext;public class backing {    public backing() {    }    public void copyAndUpdate(ActionEvent actionEvent) {        // Add event code here...        AdfELContext adfELContext = AdfmfJavaUtilities.getAdfELContext();        ValueExpression ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName.inputValue}", String.class);        ValueExpression ve3 =            AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentName1.inputValue}", String.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.DepartmentId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.ManagerId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        ve = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId.inputValue}", int.class);        ve3 = AdfmfJavaUtilities.getValueExpression("#{bindings.LocationId1.inputValue}", int.class);        ve3.setValue(adfELContext, ve.getValue(adfELContext));        MethodExpression me = AdfmfJavaUtilities.getMethodExpression("#{bindings.updateDepartmentsView1.execute}", Object.class, new Class[] {});         me.invoke(adfELContext, new Object[] {});        }    }

  • How can I get my mysqld-swamped CPU under control?

    - by Shay Guy
    I was AFK for about 24 hours and came back to find gnome-system-monitor saying all four CPU cores on my laptop were running at full throttle. mysqld is taking up more than one full core; when I tried to end the process, it restarted with a new PID. Then there's ksoftirqd/0-3, which apparently has something to do with interrupts, but I can't tell from Google what I'm supposed to do with those four particular processes. They're taking up a quarter or more of my processor cycles. Then there's Chrome, but I can probably handle that on my own -- how do I cool down the other processes giving me problems?

  • Accessing Secure Web Services from ADF Mobile

    - by Shay Shmeltzer
    Most of the enterprise Web services you'll access are going to be secured - meaning they'll require you to pass a user/password in order to get to their data.  If you never created a secured Web service, it's simple in JDeveloper! For the below video I just right clicked on a Java class that I exposed as a Web service, and chose  "Web Service Properties" and then checked the "oracle/wss_username_token_service_policy" box from the list of options (that's the option supported by ADF Mobile right now): In the demo below we are going to use a "remote" login server that does the authentication of the user/pass.The easiest way to "create" a remote login server is to create a "regular" web ADF application, secure it, and deploy it on a server. The secured ADF application can just require ADF Authentication with a simple HTTP Basic Authentication - basically the next two images in the Application->Secure->Configure ADF Security menu wizard. ok - so now you have a secured ADF application - deploy it on a server and get the URL for that application.  From this point on you'll see the process in the video which deals with the configuration of your ADF Mobile app. First you'll need to enable security for your ADF mobile application, so it will prompt users to provide a user/pass combination. You'll also need to configure security on specific features. And you can have them use remote login pointing to your regular secured ADF application. Next define your Web service data control. Right click on the web service data control to "define Web Service Security". You'll also need to define the adfCredentialStoreKey property for the Web Service data control in the connections.xml file. This should be it. Here is the flow: If you haven't already - you can read more about this in the Mobile developer guide, and Andrejus has a sample for you.

  • Oracle Brings Java to iOS Devices (and Android too)

    - by Shay Shmeltzer
    Java developer, did you ever wish that you can take your Java skills and apply them to building applications for iOS mobile devices? Well, now you can! With the new Oracle ADF Mobile solution, Oracle has created a unique technology that allows developers to use the Java language and develop applications that install and run on both iOS and Android mobile devices. The solution is based on a thin native container that installs as part of your application. The container is able to run the same application you develop unchanged on both Android and iOS devices. One part of the container is a headless lightweight JVM based on the Java ME CDC technology. This allows the execution of Java code on your mobile device. Java is used for building business logic, accessing local SQLite encrypted database, and invoking and interacting with remote services. Java concept on the UI too To further help transition Java developers to mobile developers, ADF Mobile borrows familiar concepts from the world of JSF to make the UI development experience simpler. The user interface layer of Oracle ADF Mobile is rendered with HTML5 which delivers native user experience on the devices, including animations and gesture support. Using a set of rich components, developers can create mobile pages without needing to write low level HTML5 and JavaScript code. The components cover everything from simple controls such as text fields, date pickers, buttons and links, to advanced data visualization components such as graphs, gauges and maps, and including unique mobile UI patterns such as lists, and toggle selectors. Want to see the components in action? Access this demo instance from your mobile device. Need to further customize the look and feel? You can use CSS3 to achieve this. A controller layer - similar in functionality to the JSF controller - allows developer to simplify the way they build navigation between pages. The logic behind the pages is written in managed beans with various scopes – again similar to the JSF approach. Need to interact with device features like camera, SMS, Contacts etc? Oracle conveniently packaged access to these services in a set of services that you can just drag and drop into your pages as buttons and links, or code into your managed beans Java calls to activate. Underneath the covers this layer is implemented using the open source phonegap solution. With the new Oracle ADF Mobile solution, transferring your Java skills into the Mobile world has become much easier. Check out this development experience demo. And then go and download JDeveloper and the ADF Mobile extension and try it out on your own. For more on ADF Mobile, see the ADF Mobile OTN page.

  • JDeveloper News &ndash; Did You Know

    There have been a few issues lately with access to blogs.oracle.com to write new messages – and as a result I’m a little behind on reporting the latest and greatest in JDeveloper. (I’m also unable to approve comments :-( ) But just in case you missed it here are a few note worthy things you should know: ADF Mobile Client went production – this is a solution that let you use ADF to develop on-device applications for mobile devices. You develop once and run on various devices (right now Blackberry and Windows Mobile with other platforms coming soon). For more information check out the ADF Mobile page on OTN. ADF Developer Certification goes production – you can now take the official test and get an official certification that you can include in your resume.Should be a must for any consultant looking to get ADF related gigs. Learn more about the ADF Certification Exam. ADF Vision Stencils Released – If you are looking for a quick way to draw prototypes of ADF screens you probably can’t get any faster and more accurate results than this. This is a set of Vision components that you can drag over and design a page visually. You can also set properties for components and do other advance things. You do need a license for Visio to use this, but the ADF stencils are free. We’ve been using these internally at Oracle for some time now and we thought the ADF community would enjoy these too. Download the ADF Visio Stencils here (and watch a youtube demo of how they work).

  • Working with the ADF DVT Map Component

    - by Shay Shmeltzer
    The map component provided by the ADF Faces DVT set of components is one that we are always ending up using in key demos - simply because it is so nice looking, but also because it is quite simple to use. So in case you need to show some geographical data, or if you just want to impress your manager, here is a little video that shows you how to create two types of maps. The first one is a color themed map - where you show different states with different colors based on the value of some data point there. The other is a point theme - basically showing specific locations on the map. For both cases I'm using the Oracle provided mapviewer instance at http://elocation.oracle.com/mapviewer. You can find more information about using the map component in the Web User Interface Developer's Guide here and in the tag doc and components demo. For the first map the query I'm using (on the HR demo schema in the Oracle DB) is: SELECT     COUNT(EMPLOYEES.EMPLOYEE_ID) , Department_name , STATE_PROVINCE FROM     EMPLOYEES,     DEPARTMENTS,     LOCATIONS WHERE employees.department_id=departments.department_idand Departments.location_id=locations.location_idGROUP BY Department_name,    LOCATIONS.STATE_PROVINCE

  • Developing with Oracle ADF Mobile and ADF Business Components Backend

    - by Shay Shmeltzer
    It's great to finally have the Oracle ADF Mobile solution out there. If you are not familiar with ADF Mobile - it basically lets you build applications that run on iOS and Android devices using the concepts you already know - components based UI constructions (same idea as JSF), taskflows, data controls, Java and of course JDeveloper. I created one demo that shows how to build an on-device application that gets data from local Java files (that run on the device - yes we do Java on iOS too) - you can see it here. However, one thing many of you might be wondering is how can you get data from your database into these mobile applications. Well if you already built your data access with Oracle ADF Business Components then here is a two step video demo that shows you what to do. The steps are: 1. Expose ADF Business Components as Services 2. Create an ADF Mobile application that consumes the above services with the Web service data control Simple right? That's the whole point of ADF Mobile - making on device application development as simple as possible. Try it out on your device.
