Is ADF task flows available in jdev 10.1.3.3.

Hie
I was just wondering if ADF task flow is available in jdeveloper 10g? if yes then how can i use it?

Vik,
transactions are handled in the current version as well. In JDeveloper 11 however you can add an isolated transaction context. In fact the use of page regions and page fragments is unique in JDeveloper 11 (though we had regions in JDeveloper 10.1.3 as well, but not supported).
You can work with subviews in JSF to include other parts of a screen, but this is not the same as using Jeveloper 11 taskflows. So I guess the answer is no you need to have JDeveloper 11

Why : Data Control entry not expandable/empty - ADF Task flow based on HT.

Hi All,
I've hoping to create an ADF Task flow based on a human task. I have a stand alone ADF application within the ViewController of which I am attempting to create this task flow. The resultant data control entry doesn't seem to be expandable.
Questions
1. When creating an ADF Taskflow based on a human task, should it always be within a project in the same application as the SOA components?
2. If no, is the resultant human task data control empty or not expandable because the xsd for the HT is based on the MDS? I have configured all the MDS connections within my application.
JDev : 11.1.1.4
Thanks
PP

Hi,
Answers :-
1. No, it is not necessary that your ADF Taskflow based on Human Task should be in the same application where the SOA Project Resides. But for the deployment of that ADF Taskflow you will need the SOA Project.You can add that project whenever you want to deploy.
2. It might be the cause due to the MDS Configuration .
Do one thing , while creating the ADF Taskflow based on Human Task , you do select the .task file via the file system not from the MDS.
If you will select the .Task file of your soa project then it will ask you to name the Taskflow, just name the taskflow as you want and say ok.
After creating the taskflow, it will add a lot of xml files in your project and it will create a data control of it.
Hope it helps!!

Shah

ADF Task Flow: Using Task Flow Call as Application Entry Point

In our product we have a task flow structure very similar to the Fusion Order Demo application, but we are having serious trouble reproducing the documented functionality of ADF Task Flows.
Specifically, we cannot use a task flow call as an entry point for our application, which is very important for us to achieve.
The [Developer s Guide|http://download.oracle.com/docs/cd/E12839_01/web.1111/b31974/taskflows.htm#ADFFD1634] states about the [demo application|http://www.oracle.com/technology/products/jdev/samples/fod/index.html] :
"A Fusion web application always contains an ADF unbounded task flow, which contains the entry point or points to the application. Figure 14-3 displays the diagram for the unbounded task flow from the Fusion Order Demo Application. This task flow contains the Home, *MyOrders*, *checkout*, registerUser, and updateUserInfo *view activities, which are all entry points to the application*."
"The checkout-task-flow activity in Figure 14-3 is a call to an ADF bounded task flow."
When we run the Fusion Demo Application, we are only able to use home, updateUserInfo and register as entry points.
We cannot enter the application through any of the task flow call activities (MyOrders and checkout) as the documentation suggests.
What are the reasons for this and how do we fix it, so we can use task flow call activities as application entry points?
Thanks.

The forum did not display the link to "Developer's Guide" because the link contained the single quote char '. Single quote char removed.

Is what you mention here the case in the Fusion Order Demo application?
If the task flow call activities cannot be used as entry points, why is it stated in the documentation?
How do we solve this, so that the task flow call activities (including parameter bindings) can be used as entry points, like the documentation suggests?

How to get the logged in userId value in adf task flow OIM11g R2

Hi,
I have created an adf task flow. Now I want to run some query in that based on the logged in userId.
Could you please help me in knowing how to get the logged in userID value in adf TaskFlow so that I can run a parameterized query.
Thanks

3 different ways to retrieve the username (not sure what you mean by user ID) :
http://mahmoudoracle.blogspot.be/2012/06/adf-get-current-logged-user-name.html#.USI_c-h8zIo
Also provide your JDev version.
Basicly, you should use the groovy expression in a view criteria (it's the fastest and easiest way) and call that view criteria whenever you need it.
That's if you are using ADF BC of course.

How to get the logged in userId value in adf task flow

Hi,
I have created an adf task flow and deployed the same in application as an adf library.
Now I need to get the Logged in User ID value in the adf task flow which I created.
Based on this userid I need to run query to fetch the data related to the user from the database.
Please help/guide me to solve this issue.

11g TP2 ADF Task Flows and Transaction Management

I'm wondering how ADF Task Flow Transaction Management works vis-a-vis database sessions and using stored procedure calls in an environment with connection pooling. I haven't written the code yet but am looking for a better understanding of how it works before I try.
Example:
I create a bounded adf task flow. I set the "transaction" property to "new-transaction" and the "data control scope" to "isolated".
As the task flow is running, the user clicks buttons that navigate from page to page in the flow. Each button click posts the page back to the app server. On the app server a backing bean method in each page calls a stored procedure in a database package to modify some values in one or more tables in the database. The procedure does not commit these changes.
Each time a backing bean makes a stored procedure call will it be in the same database session? Or will connection pooling possibly return a different database connection and therefore a different database session?
If the transaction management feature of the adf task flows guarantees me that I will always be in the same database session then I don't have to write any extra code to make this work. Will it do that or not?

I don't know if it is documented in the adf documentation currently available for 11g TP2 but what you ask for is a normal transaction management with connection pooling and i can't imagine it is not implemented in ADF BC layer like it is in JPA or other persistence layer.
A transaction will always be executed in the same session. Normally your web session will stay in the same session even you start more than one transaction. You don't have to write any code to manage the session pooling. It is a good practices to customize it at the persistence layer during installation depending on your infrastructure.
Take a look into Fusion Developer Guide ... i'm sure you will find some better explanations about this.

Creation an ADF Task Flow Based on a Human Task

Hello!
While creating ADF Task Flow Based on a Human Task, I can't bind New TaskFlow to task, which I choose in Dialog.
Details:
I Have:
BPM Project with PackageCreation.task
ADF Project in Same Application
I do:
1. in Application Navigator right click on ADF Project -> New -> Web Tier -> JSF -> ADF Task Flow Based on a Human Task
in creation Dialog I choose PackageCreation.task and Don't change name of New TaskFlow (automatically JDeveloper set this name to PackageCreation_TaskFlow)
I have After that:
new ADF Task Flow and my old PackageCreation.task.
Question:
Why my Task don't bind to created ADF task Flow based on it?
I think, that while creating ADF Task Flow Based on a Human Task it has to change my task, writing some thing like This (inside xml):
<taskFlowFileLocation>file:/D:/JDeveloper/mywork/SalesQuoteLab/EnterQuoteUILab/public_html/WEB-INF/EnterQuoteDetails_TaskFlow.xml</taskFlowFileLocation>
That xml element is creating in xml of *.task, while making auto-generation form for human task in BPM Project.

Juan C,
I use JDeveloper 11g Release 1.
May be I didn't explained my question correctly.
taskdetails1 is creating, and in Data Controls I have objects of my BPM Human Task Payload.
But in that file "PackageCreation.task" in source I can't find any link to instantly created TaskFlow.xml in my UI project.
So, I have
NEW project "PackageCreationUI" with PackageCreation_TaskFlow.xml in it (and TaskDetails1 file too).
AND Did't Changed PackageCreation.task in BPM Project.
If I use *"BPM form creation wizard"*, after creating project and TaskFlow in it I see Changes in PackageCreation.task in BPM Project, something like that:
<taskFlowFileLocation>file:/C:/JDeveloper/mywork/testApp/PackageCreationUI/public_html/WEB-INF/PackageCreation_TaskFlow.xml</taskFlowFileLocation>

What is difference between ADF Task Flow and Faces-Config - when delpoy ?

What is difference between ADF Task Flow and Faces-Config? When I create navigation between pages with ADF task flow then the navigation don't work when I deploy my application to Weblogic 10.3. When I use default server then navigation works fine. With Faces_config in both situations all works ok - on Stanalone server and default.
Where is the problem?
Best regards!

Shay, I don't use both faces-config and adf task flow! When I failed with task flow I tried faces-config.
I have active on my weblogic - adf.oracle.domain(1.0,11.1.1.0.0). This is the right ADF? If yes then where is the problem?
Best regards!

Error while deploying the ADF task flow project based on a SOA human task

Hi,
I created a SOA project with a BPEL process containing Human task, deployed it and could able to test it successfully. I created ADF task flow project based on the Human task created in the earlier project and tried to deploy it. It is giving the following error.

Apart from these, I have Model and View Controller projects in the application. If I create the ADF task flow based on a Human task in another sample application, it works fine. Only in this application, it does not work. Not sure what this error is. Any ideas?
Thanks,
Manoj

What I suggest is go into EM and undeploy this composite and all versions. (Only if you don't want the existing ones). Then redeploy your process. This will avoid the version conflict and create a new version. 1.0. Then the next time you try and deploy you need to either specify a new version or check the box to say the version can be over written.
cheers

Separate project for each ADF task flow?!

Hi,
We have a BPM process application which is having a few human tasks. The form for each of the human tasks is similar. We’d like to be able to share some page fragments or code between them and create single web application to handle all the human tasks for this BPM process application. Then I found the following in the Oracle document “Developer’s Guide for Oracle SOA Suite 11g Release 1 (11.1.1.4.0)”:
“If the SOA composite contains multiple human tasks, create a separate project for each ADF task flow associated with each human task.”
I wonder if we have to do that and if so, what is the reason.
Do you have any clue? Please help.
Thanks a lot,
Helen

Create Custom ADF Task Flow for BPM

Hi,
I'm working an project on BPM and I'm required to create a custom ADF task flow with multiple views based on the human tasks in BPM. Since I'm new to ADF, could some one please give me some pointers?
Thanks,
Debojit

Hi,
You have to implement your own custom worklist screens for such a subject. As you know the OOTB worklist screen shows the logged-in users' assigned, etc. tasks. You have to implement the API of SOA workflow.
You can check Mark Nelson's blogs on Redstack to accomplish this. Hope this is the answer of the problem you are looking for.

Hi Helen
1. I do not know the reason why they mentioned like separate project for each human task. NO, this is not required and we can have just one UI Project like MyTaskForms and have all the JSPs in this same project for each Human Task.
2. On our side, we have like 10 Human Tasks, all using the same Payload. So we have 10 .task file. For the very first .task file, we used Auto Generate Project and gave project name like OurAppTaskForms. The reason we did this is, so that it adds all the required dependent libraries, tag libs etc properly. For all remaining 9 .tasks file, we did NOT use auto generate. Instead we used standard New -> JSF From Human Task and select one task at a time and follow the steps. These steps are covered in the online documentation. At the end in our BPM App, we have just one UI Project with all the 10 screens.
3. ALSO, all the 10 screens have some common data. This we put in a reusable JSF Fragment page. And associated a custom Managed Bean for this to set and get values from this fragment and also some Actions for some buttons in the JSF. Then we included this JSF in each taskform jsf file, uisng the include tag. We added this include tag, somewhere in the top. So all screens share common jsf fragment page.
4. We can refine the above stuff further. As per above, we still have 10 JSF screens for each one of the 10 .tasks. Ofcourse all these 10 jsf have same common jsf fragment. BUT instead of 10 individual jsf screens, we can have only ONE Jsf screen also. Refer online docs for the details. The challenging part is, since we have only one jsf, there may be some bussiness stuff, validatoin stuff to take care of in custom ValidationCallback Handler classes. Say for Task1, we had to show some buttons, but NOT for Task2. So we had to handle this logic. Also in validation call back, we can always get each Tasks, title also. So we can workaround this issue also. We are in the process of doing this right now. But first 3, we already did and they are working fine.
My personal suggestion is first go with single jsf fragment and include in all tasks jsp files. Any changes to common elements need to make only in one place i.e fragment page.
Thanks

Oracle ADF task flow setup failing- deployment issue

Hi Experts,
We are facing issue while deploying the ADF taskflow to Oracle webcenter portal/application server.
We will need your help to get any pointers from your Oracle network to help resolve.
Details of issue are as below.
Please help ASAP.
Problem Statement: Issue in the ADF taskflow while it is deployed on Oracle Webcenter Portal/Application server (the ADF taskflow is fetching data from PL/SQL procedure using table/record objects as OUT parameter, which is running fine in Jdeveloper).
Problem Description:
From ADF task flow we are invoking a PL/SQL procedure, which is returning a PL/SQL objects as an OUT parameter, some of these objects are of TABLE TYPE and one of RECORD TYPE. We are invoking this oracle procedure and fetching the object using jdbc. The object to which we are mapping this PL/SQL object is a custom java type object. We are using Jdeveloper 11.1.1.4 and Oracle ADF for this and we are able to successfully fetch the object using the code snippet #1 attached below.
However, when we deploying the same code, i.e. the above ADF task flow in the Webcenter Portal server 11.1.1.4, inside the Webcenter portal application, it doesn’t work and give the below error, error snippet #2 below.
Options tried: Initially we were using oracle.sql.STRUCT to handle the PL/SQL object, we tried changing this to weblogic.jdbc.wrapper.Struct and also java.sql.Struct, however we are still getting same error.
The objective is to get the data from PL/SQL procedure in objects (record, table) as OUT parameters in ADF taskflow deployed on Oracle webcenter portal/application server.
******Code Snippet #1**************************
txn = getDBTransaction();
Connection con =
((DBTransactionImpl) txn).getPersistManagerConnection();
st = (OracleCallableStatement) con.prepareCall(callfetchOA);
st.setString(1, so_number);
st.setString(2,
generate_pdf); //generate_pdf should be passed as N in case of FetchOA and Y in case of Generate PDF
st.setString(3, so_line_id);
st.registerOutParameter(4, OracleTypes.STRUCT, headerTrxObj);
st.registerOutParameter(5, OracleTypes.ARRAY, lineTrxTypeObj);

Maybe this can help you: http://mike.hostetlerhome.com/2007/02/12/weblogic-oracle-and-blobs-oh-my/
It shows how to obtain a vendor object from the weblogic wrapped instance.
From the blog
weblogic.jdbc.wrapper.Blob cast1 = (weblogic.jdbc.wrapper.Blob) o;
BLOB myblob = (BLOB) cast1.getVendorObj();

Create ADF Task Flow for Human task outside of SOA Composite

Hi,
Is there any way you can create ADF Task Flow form (for the task Details to be display in worklistapp) for a Human task out side of the SOA Composite applicaiton?. I know we can create ADF Task flow form for task details based on Human Task in SOA composite application. But I dont want to do that. I dont want to keep any association between Human task and ADF Task Flow.
If there is a way to do this, How can we assiciate this ADF Task flow form with worklist applicaiton?
Thanks

Is ADF task flows available in jdev 10.1.3.3.
