How to call an adf task flow in a commandNavigation tab

Hi,
I have created an adf task flow, I am able to invoke the same on click of a link.
Now I have a tab and some sub tabs under it. I want to open this adf task flow on click of one of these sub tabs.
For this I have added a property of type CommandNavigationItem in parallel with exising subtabs and on the actionListener of this property I am calling the method of the adf task flow.
But it is not working. When I click on the sub tab created by me I get this error on the logs :
ADF_FACES-60096:Server Exception during PPR, #1[[javax.servlet.ServletException
Please help/guide how to solve this issue.

Hi,
do you use the XML Menu Model? If so then the task flow must be referenced from a navigaqtion case in the unbounded task flow you turn into the menu model

Passing input parameters to the method call in ADF task flow.

Hi,
I have the following use case:
There is a task flow with 2 jspx pages. In the first page I have 2 input search parameters and search button. the search button calls the webservice data control execute (GET_ACCOUNTOperation) method .
Displaying the search results in the same page is not a problem , but my requirement is that the search results are to be displayed in the second page in tabular form.
To achieve this, I dragged the execute method as the method call in the task flow and specified the input parameters for the method call (right click and add parameters) . I am getting the following exception :
javax.el.MethodNotFoundException: Method not found: GET_ACCOUNTOperation.execute(java.lang.String, java.lang.String)

even though the execute method is there and the service is up and running. I am not sure whether its the correct way of doing it. Please shed some light on how to solve this use case
Some additional info:
Under the data controls pallete, the GET_ACCOUNTOperation method has a parameters section , which has "part" (java.lang.Object) as
the input parameter.

Hi,
thanks for the quick turn-around. Jdev version that i am using is Studio Edition Version 11.1.1.6.0. And i am using SOAP. Isnt there a way without using a backing bean? I am planning to use it as a portlet. Would'nt creating a backing bean cause a problem in that case?? Also i am confused here . The method that i am dragging is GET_ACCOUNTOperation(Object). I tried passing the hashmap . It gave the following exception :
javax.el.MethodNotFoundException: Method not found: GET_ACCOUNTOperation.execute(java.util.HashMap)

How to Call an ADF Bounded Task Flow Located in Another Web Application

Hi.
I'm working in JDev 11G TP3.
I've read the section from the 11G documentation on Working with Task Flow Activities,
specifically the section 15.5.3 on How to Call an ADF Bounded Task Flow Located in Another Web Application.
I've followed the instructions but still can not seem to call another task flow in another application correctly.
Can someone send a small example specifying how the (TaskFlow Reference) section
should be filled in, and just a general simple outline of process to set the whole process up.
Thanks

Your EL for the remote-app-url needs to return something like this
"http://www.acme.com:80/myapp/faces/adf.task-flow"
where "http://www.acme.com:80/myapp/faces" is the root of the url you'd normally use to access the remote application.
I filed two bugs:
bug 6944247 to improve the documentation
bug 6944246 to fix the fact that you currently have to specify the 'adf.task-flow' part. You shouldn't need to do that. But doing so for now will get it to work.

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

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 deploy a new ADF task flow in OIM 11g R2

Hi,
I have created a new ADF task flow.
Now I need to deploy the same in OIM 11g R2, so that when I click on a link it will call my new ADF task flow.
Please help me in identifying the steps required to deploy the adf task flow.
Thanks

Hi Durga,
Thanks for sharing the post. I think I am facing the same issue which you were facing.
I have already done these steps but still not able to get my custom page on click of a link which I created in OIM self service page :
1. I have created the adflibHomepagePortletsUI.jar as an adf library using Jdeveloper and copied it to oracle.iam.ui.custom-dev-starter-pack.war --> WEB-INF/lib folder after unpacking it.
2. have updated the custom-catalog.xml file inside oracle/adf/rc/metadata folder with the below lines :
<folder name="Sample Folder" id="sampleFolder">
<contents>
<resource id="helloWorld" name="Hello World"
description="Hello World Taskflow Reference"
repository="application.classpath"
path="adflibHomepagePortletsUI.jar/ADF_TaskFlow/WEB-INF+oracle+iam+ui+sample+homepage+tfs+hello-world-tf.xml#hello-world-tf">
<attributes>
<attribute value="coreDefault" attributeId="attr.background" isKey="false"/>
</attributes>
</resource>
</contents>
</folder>
3. repacked the war file and copied it in OIM_HOME/server/apps directory
4. Restarted the OIM server.
5. entered the following lines in jazn-data.xml present in user_projects\domains\idmdomain\servers\oim_server1\tmp\_WL_user\oracle.iam.console.identity.self-service.ear_V2.0\6bddg\META-INF\jazn-data.xml
<permission>
<class>oracle.adf.controller.security.TaskFlowPermission</class>
<name>/WEB-INF/oracle/iam/ui/sample/homepage/tfs/hello-world-tf.xml#hello-world-tf</name>
<actions>view</actions>
</permission>
5. Login to self service console.
6. Click on the custom link who's actionListener is pointing to bean which is launching the taskflow created in the above steps.
7. On Click of the link a new tab gets open with blank page.
Please help me in knowing the step which I am missing in order to solve this issue.
Many thanks once again.

How to insert values in table using ADF Task flow? I am not able to bind CreateInsert on my first page fragement

Hi,
In Jdeveloper 12c I am trying to create a task flow where I have taken 3 pages to insert values in a table. On first page when I put data control of 2 columns as input with label, then on bindings tab I created an action as CreateInsert.
Now when I am trying to create invoke action in executables then this option is not available.
How can I create this task flow where values can be inserted in the table on the 3rd page fragment on commit button???
All 3 pages have data control input boxes to insert values in the table.

Hi,
Right click on the task flow page activity, click create page def and add there. If your activity is a page, then you can select the page and generate the pagedef as well.
Then you can add the executables.
Thanks.

ADF task-flow and transactions

Hi All,
I have created a web application using ADF and JDeveloper 11.1.1.4. The ADF web application has two pages 'Search' and 'Edit'. The 'Search' and 'Edit' are page fragments. I have two bounded task flows 'search-flow.xml and 'edit-flow.xml'. The search and edit functionality has been created as dynamic regions by dragging the task-flows onto the JSF page.
The bounded search-flow.xml has page flow from search ----> edit(Parent Action component)
The bounded edit-flow.xml has page flow as *-->edit----> search(Parent Action component)
User comes from login page to the search page. On search page users can choose to search for records and edit individual searched records or create a new record using 'CreateInsert' button. Either way users end up on the edit page.
On the edit page, users see a form to fill or modify. They have the choice to navigate back to search page using 'Search' button or commit changed record using 'Save' button or create new record using 'Create' button
The application is functioning 90% as expected, only problem is the transaction management part if the user does not care to save each time the edit is made.
Say for instance, on search page user press ' CreateInsert' button which takes the user to edit page and then without saving the new record user presses 'Search' button which takes the user to search page and so repeated goes back and forth cycle.
In such cases the transaction never ends, The primary key for each new record is retrieved from the DB sequence only on persisting to database. A place holder like negative integer is used for the primary key temporarily till new record is persisted to database.
As per best practices, I am using the checkUncommittedDatabehavior which prompts the user when navigation is done away from the edit page i.e. without saving on pressing the 'Search' button on edit page. User can choose 'OK' or 'Cancel' which comes bundled with the ADF checkUncommittedDatabehavior property. Even after selecting OK the new record does not seems to be rollbacked (Issue 1).
eg:, if the user performs the cycle(i.e navigating between search and edit pages without commit/save) 'n' times, new entity records are created with primary keys -1, -2, -3, -4 ........ so forth. As I said earlier a proper sequence number for the primary key is assigned only if a record is persisted to the database.
Now on the 'n+1' cycle the user fills the records and clicks commit, it comes up with a error 'primary keys with nulls from previous uncommitted record (i.e; 1,2,3, .....n) creation.
I guess the transaction management is not happening correctly and not completing during these cycles (1, 2...n) Note: I am not using 'Task Return' components in my bounded ADF task flows, just commit operation 'Save' button in edit page and checkUncommittedDatabehavior.
Also, in search-flow.xml I have following configured under 'Behavior' tab Transaction ---> No Controller transaction and ' Share data controls with calling task flow checked
in edit-flow.xml, these configurations are in place under 'Behavior' tab Transaction ---> Always begin new transaction and ' Share data controls with calling task flow checked and Critical checked and 'task flow rentry' as reentry-outcome dependant.
Thanks

Hi Frank,
I checked the DB sequence is setup correctly. I have also modified the problem description above for better understanding.
2. When users press OK, navigate to a commit method activity (just drag and drop the commit operation).
-- When user presses OK, I need to rollback instead of commit to make users lose the unsaved work and controller should navigate to the search page. Here, the message panel with Cancel and OK is shown automatically with the <af:checkUncommittedDataBehavior/> property, I thought the framework will do the rollback for me. If I need to do rollback manually, how to do it, because I cannot see the JSF related source code for the <af:checkUncommittedDataBehavior/> dialog box. Please suggest what to do
3. If they press cancel, have the return activity rolling back to the save point taken when the user entered the bounded task flow (edit task flow)
-- If they press cancel, user stays on the same page, so I will leave future action to the user. This bit is working fine in my app.
Thanks

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.

Do some processing before loading jsf fragment created using adf task flow

Hi,
I am working on JDev11g.
I want to create SelectItems of SelectOneChoice dynamically before loading jsf fragment created using adf task flow
I tried by implementing RegionController class's method RefreshRegion in my backing bean of jsf page fragement to do some processing before loading region
But it seems to be not feasible approach because it is getting called every time any component on fragement gets partially submitted.
Is there any method which is called only first time when region is loaded ?
Or any other solution to achieve this.
Regards,
Devang

Hi,
don't think so. You would need a phase listener, but I don't see how you get it in. Wha about using a dynamic region and then use the method that is called from the dynamic region first time it is rendered?

Why Dev Guide says "create a 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

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);
st.registerOutParameter(6, OracleTypes.ARRAY, fetchFeeLineTypeObj);

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
