ADF 11g Taskflows and PageFlow Scope.

Hi,
I am working in ADF11g and I have a question on ADF Taskflows and PageFlow Scopes.
I have 2 bounded taskflows a and b. a is in showdetailitem1 and b in showdetailitem2. I have created a bounded taskflow on a and b and dropped on a page.I have some values set in page flow scope of a and when I try to retrieve those values in b, I get them as null.
Can anyone tell me what could be wrong.
Thanks,
User

Hi,
As i understand, each bounded taskflow will have a separate pageFlowScope. I believe, I have read this before in the documentation but now having a hard time finding it. If you need to share the same variable between bounded taskflows, you can look into taskflow parameters or contextual events. Another dirty and easy way is to use session scope (not recommended if can be avoided).

Pino

ADF Taskflows with EJB and pageflow scope

Hi,
I am trying to create a simple registration page which is very simillar to FOD customer registration using EJBs instead of ADF BC.
I can achieve the registration in one page but I wanted to try this using a wizard based process using ADF taskflows.
I created a bounded taskflow with 3 pages. page1 is employee details, page2 is job details, page 3 is the summary page. I have JPA entities for Employee and Jobs and an EJB3 session Facade. I have used the Employees default constructor to create the UI bindings from the constructor section of the data controls. This creates an EmployeesIterator which I use it for bindings on all the three pages.
My question is can I use this Iterator binding in pageflow scope? If yes How do I do this?
The other way is to use a managed bean in pageflow scope and have UI bindings to the variables in managed bean. This option will work but I will not be utilising any of the features of ADF bindings.
Can anyone please suggest which is the better option.
Thanks
Venkatesh

Hi,
pageDef files can be shared, but their instances aren't. The caching is on the data control side, which means that instead of using a constructor you would break up the input form into method calls like
createPerson(String, fn, String ln, String address)
createInterest(String hobby1, String hobby2);
dagging and dropping the method calls should the reate an input form. Submitting the forms allows you to build a new person object on the session facade which at the end is committed. This way the ADF binding works across pages, operating on a single new object

Oracle ADF 11G R1 and 11G R2 and Internet Explorer 11 Support

Hello,
We are using Oracle ADF 11G R2 (11.1.2.4), and now that Microsoft has pushed Internet Explorer 11 to Windows 7 and Windows 8 computers, we are finding that our application is not working with IE11.
You get the popup that states "You are using an unsupported browser", and while everything renders on the screen, the application does not respond to user clicks.
Does anyone have workaround for IE11, and if anyone from Oracle is reading, can you give any tentative guidelines for IE11 support.
Thanks.

Here's one workaround

Hi Chris,
thanks for your response. I was take next fragment of source code for Server session, Client session and Remote session.
On server side:
Acquire Server Session:
private synchronized void createServerSession(boolean setEventListener){
serverSession = null;
if (toplinkProjekt == null) return;
Server serverSess = toplinkProjekt.createServerSession();
if (setEventListener) {
SessionEventListener eventListener = new SessionEventListener("ToplinkProjectManager.createServerSession", true, ESessionType.ServerSession);
serverSess.getEventManager().addListener(eventListener);
serverSess.setLogLevel(DefaultSessionLog.ALL);
serverSess.login();
serverSession = serverSess;
Acquire client session:
public RMIRemoteSessionController getRemoteSessionController(String firma) {
RMIRemoteSessionController rmirsController = null;
try {
ClientSession clientSession = getClientSession(firma);
if (clientSession != null) {
try {
rmirsController = new RMIRemoteSessionControllerDispatcher(clientSession);
} catch (RemoteException e) {
e.printStackTrace();
} else {
System.out.println("\n" + userIdentifikator + "\nzamietnuty pristup.\n\n");
} catch (Exception e){
e.printStackTrace();
System.out.println("\n\n\n" + userIdentifikator + " dostal RMI controller: " + rmirsController+ "\n\n\n\n\n");
return rmirsController;
private ClientSession getClientSession(String firma) {
if (AccessControl.canAccess(firma, userIdentifikator)) {
return DBConnectionManager.getClientSession(firma, userIdentifikator);
} else {
return null;
Methods getClientSession and getRemoteSessionController are in Statefull EJB T3ConnectionManagerSessionEJBBean and getRemoteSessionController is published accross the Remote interface.
Remote site:
private static Context getInitialContext() throws NamingException {

Oracle ADF 11G R1 and Internet Explorer 11 Support

Hello,
I need to write my own post even if issue is written on this thread (https://forum.java.sun.com/thread/2602720) Because i suppose that post writer reached to his useful workaround and no activity seems for a couple of months.
Use 11.1.1.6 and Win8.1 IE11
I did not find any solution or workaround which runs properly. Any comments are welcome.
merry christmast

The reason for this is that there is no solution at the moment. Oracle is working on one. Also check https://groups.google.com/forum/m/#!msg/adf-methodology/NP4g98AvrCw/uYf_cvDna_0J
To my knowledge you have to open a SR with support.oracle.com and ask them for help to get the back port of the solution once it's ready.
If you have a support contract you'll find a note for IE11 THERE too.

Scrolling of an adf 11g component and tying it to browser scrolling

Hi,
Is there anyway to somehow defer scrolling to browser from an adf container component. Let me explain to you what i mean.
Lets say I have a jspx page with some content that requires browser to vertical scroll. Now If i create a form in a scrollable container with several input fields and add that container with form to my jspx page, i get two scroll bars (one internal to my page, the other specific to browser). Since most of us hate double vertical scrolling, i was wondering if there was something i can do to in essence add my internal scrolling to the browser scrolling.
It may be impossible to do, but it is a real requirement. Of course i can create my form that is not scrollable and then only browser scrolling will be needed.
Thanks,

Hi,
I think this requires JavaScript interaction to synch the scrolling with the browser bars. I am not aware of anyone who did this so far.

Issue in Creating EAR File Using ANT in ADF 11g of Jdeveloper11g IDE

Hi
Rookie to this ADF 11g Framework and during the exploring of ADF 11g gone through ADF essentials in OTN and i did sample application of ANT build script and in the ADF Essentials of Ant i came across creating build.xml,build.properties and finally creating WAR file and currently i want to create EAR file so that EAR file can be deployed to my oracle Weblogic server.But ADF Essentials of ANT is totally confined to build.xml,build.properties,WAR file only ! Can any one suggest me the template build.xml of EAR file of any Sample Application so that i can come across what are the patterns,jars,excluded names,included names of EAR .
Thanks In Advance,
Regards
RK

RK,
There are a few options. If I were doing this today, I'd just use ojdeploy (and the ojdeploy ANT task) to create the EAR file with a minimum of fuss (refer to the JDeveloper docs for more information).
If you wanted to create an EAR file using the same technique that I used in the ADF Development Essentials article, just follow the same techniques - create an EAR file using JDeveloper and unzip it to discover the structure of what it should look like.
Best,
John

ADF 11g TP3 or Production

Is there any information out there as far as Oracle's delivery dates for ADF 11g Production and/or an ADF Technology Preview 3 version? We are currently in the process of developing a small beta version of our software using TP2, but concern is mounting due to components not being completely reliable. Obviously, attaining our beta deadlines is greatly affected by Oracle's ADF 11g deadlines. Any info is greatly appreciated! Thank you.

Hi,
unfortunately we don't have a release date for JDeveloper 11 and no date for another TP either (which doesn't mean that there wont be anymore TP - just we don't have a date yet)
If you are building on an important proof of concept, I suggest you to get in touch with the local sales organization to see how they can support you. There are limited options to provide you with internal builds after signing a non disclosure agreement. However, as said - resources are limited and we cannot accept all requests. However, your local sales team is the first stop to getting there.

[ADF-11.1.2] Using Pageflow scope MB in pages is throwing TargetUnreachable

Hi,
I have a BTF with one MB "TempBeanVar" Configured as pageFlow scope.
I then configured created one page (.jsff) which is called in above BTF.
On that page: I have created a button with actionListener = <af:commandToolbarButton text="View" id="ctb1" actionListener="#{TempBeanVar.onView}"/>On Web browser: I click on button, I get following error message but when I change the scope of "TempBeanVar" from pageFlow to Request, and re-run the page, It calls onView method of MB w/o any error.
I don't understand, if we can using pageFlow scoped MB in any of activities (it's working in method calls), why I can't use in page activities (called from same Task flow).
Note: When I try to edit actionListener Property in jDeveloper, It is showing "TempBeanVar" as one of value in Managed Bean drop down but also showing - Reference "TempBeanVar" not found - warning message in jDeveloper when the scope set to pageFlow in BTF.
Error Message on Browser:

For the record this is just a peculiarity of Oracle's JSF solution. The standard JSF bean scopes don't require a scope qualifier in the EL expressions, but Oracle's pageFlowScope & backingBeanScope scoped beans do.

Can we call a method before and after Export operations in ADF 11g

Hi,
My problem is I have to execute a method before and after the export operation.Is this posible in ADF 11g
Regards,
Felix

Hi,
in response to a similatr post of yours, I replied
1. Drop af:exportCollectionActionListener on a command button
2. set the command button to display = false
3. In your Java code, call
ActionEvent ae = new ActionEvent(button);
ae.queue();
Everything you put before
ActionEvent ae = new ActionEvent(button);
ae.queue();
will fires as a pre-trigger, everything after as a post trigger

What are correct steps of integrating and using jasper report with ADF 11g?

Hi,
I am using JDev 11.1.1.2.0 with ADF 11g.
I want to use jasperreports 3.7.0 along with ADF 11g to build reports in PDF on a button event. This is the first time I will be attempting it so before starting up I went through forum to get exact and clear steps on the jars and integration points of jasper with adf. There is exhaustive list but still it does not have the needed clarity.
Can anyone help in listing down the jars and integration steps? and also want to know if there are any points in particular that I need to be aware of while running i along with ADF faces.
Pls note the ver. of jasper and adf mentioned above.
Thanks in advance.

Hi,
Basically, you need to:
- have all the jars in ViewProject/WEB-INF/lib, and include them to the project (Project properties -> Libraries and Classpath) - last time I did this was with version 3.1.3 and the necessary jars were jasperreports-3.1.3.jar, jcommon-1.0.0.jar and iText-2.1.4.jar (plus poi<+whatever is the latest version+>.jar if you want to generate .XLS reports)
- call the code for generating reports from your backing bean (button's actionListener)
- flush the report to the client (directly to HTTPResponse or by using af:fileDownloadListener)
Those are the general steps, without going into the coding.

JDeveloper and ADF 11g Release 2(11.1.2.0.x) compatible WebCenter Version

We are looking to upgrade ADF to 11.1.2.0 and looking for WebCenter compatibility.
Could you please let me know WebCenter compatible version for JDeveloper and ADF 11g Release 2 (11.1.2.0.x) ?
Thanks
JP

Looking at 11.1.2.0.0 note on
http://www.oracle.com/technetwork/developer-tools/jdev/downloads/index.html
and seeing, "This version of JDeveloper doesn't include the SOA and WebCenter pieces - to use these components you'll need to download Oracle JDeveloper 11.1.1.5.0."
Does that mean, 11.1.2.0.0 can't be used with WebCenter?

Stress test tool and guidelines for tuning ADF 11g

Hi all,
I am working our ADF 11g application on load & stress testing. The load test works fine with some millions of full dummy rows (this generated data tool is easily written by ourself). The tunning only was done with only indexing. But with stress I'm concerning with RAM and other tunning parameters such IO and share pool from OS to DB and to WL servers and how to tune it for around 200-300 concurrent connections. I'm studying Jmeter for this purpose but still not get the answer. I have tested with Oracle Openscript but it worked very heavily slow :(.
The question here is that do you have any experiences on tuning parameters for such requirements and what is the best automatic test tool for testing multi-connections, please advise me.
Thank you very much.

Oracle Application Testing Suite has specific support for ADF testing:

OpenScript recording is slow with FireFox and ADF 11g

Hi everybody;
I trying the OpenScript for recording some scenarios, and I am facing some problems:
1- When I use the internet explorer (IE) it records fine with an acceptable speed, but when I replay the recorded script it misses out the fields and the links that I clicked, meaning: it starts to highlight other places on my page which I didn’t click while I was recording.
2- When I use FirexFox, I get other kind of problems. First the recording is unbelievably slow. It might take a minute or two for every link I click to respond. Also when I replay the script it executes faster than it did while recording but much more slower than doing the same scenario in real time meaning: doing it directly on the browser by a real user.
Kindly note that my application is an ADF 11g application with EJB3 and the application server is Weblogic 11 and the database is oracle 10g.
Any ideas will be appreciated
Thank you all
