Human Task Bulk API calls from ADF Entity Object

Dear all,
Jdev: 11.1.1.7.1
We have a requirement where in human task APIs need to be invoked on status changes of an ADF Entity (EO). We presently achieve this in the afterCommit() method and all is well.
But we are looking to leverage the Human Task bulk update APIs and am wondering how to do that.
The EO does support a batch mode - Is there a batch mode API that we can override to place the bulk update API call?
Thanks

in version 11.1.1.6 getInputStream() and getContent() do not work, this is know bug you can find in the oracle support at
https://support.oracle.com/epmos/faces/ui/km/SearchDocDisplay.jspx?_afrLoop=175895926830291&type=DOCUMENT&id=1451100.1&displayIndex=8&_afrWindowMode=0&_adf.ctrl-state=tlzphlagm_69
there you can find a .zip file with a full example code.
Actually Oracle does not consider it a bug:
"This issue was reviewed by Engineering in Bug 13873092 and is not considered a bug. There is a workaround to retrieve task contents through 'WFTaskUpdate' Servlet as described in the attached Sample project."
but in my opinion it is a very big bug endeed, and it drove me mad for days! :(
Anyway here is a snippet with the workaroud in case you do not have access to the oracle support site:
if att is you attachment and wfContext is your workflow context set somewhere
AttachmentType att;
IWorkflowContext wfContext;
instead of doing this
InputStream inputStream = att.getInputStream();
do this
String contextId = wfContext.getToken();
String attachmentURL = WFUtils.getTaskUpdateURL(att.getTaskId(), contextId, "" + att.getVersion(),att.getName(),
Constants.WFTASK_QUERY_ATTACHMENT_BUTTON_KEY_NAME);
if ( attachmentURL == null ) {
System.out.println("Unable to generate URL to get attachmentcontent");
try {
URL url = new URL(attachmentURL);
URLConnection conn = url.openConnection();
InputStream inputStream = conn.getInputStream();
} catch ( Exception e ) {
e.printStackTrace();
hope this helps

Human Task Java API

Hi
I have a requirement to create human tasks without using soa. I am trying to use the Human task Java API. Using this API I can do all the operations like updating the outcome, adding/updating comments and updating assignee list but not able to create initial task. I am using initiateTask operation which requires task definition id. I dont know how to set this. Can anybody guide me
1. Can I create human tasks without using composite pure java api?
2. If I am able to create initial task what will be the task definition id? I tried to enter a new row in soa infra meta data table which did not work.
I really appreciate the help.
Thanks

Hi Sri
I have few Processes deployed to my SOA Domain and that too under different Partitions. For ease of maintenance, in EM Console under soa_infra node instead of default partition we can have our own Partitions also to deploy specific workflow projects under those partitions. If you don't have this thats ok.
I looked at Payload data for all the Tasks submitted by the first Initiator Task in EM Console, when we check the Flow Trace etc. Here is what I found for <taskDefinitionId> value for each of my different Processes. They do have some Pattern. So you had to use some sort of properties file to get these values so that if they are deployed to different partitions and with different versions, you do not have to modify your java code and recompile it. Just modify .properties file.
Anyhow, looks like the format for <taskDefinitionId> is something like this:
NameOfPartition + "/" + NameOfProcess + "!" + VersionNumber + "/" + NameOfInitiatorHumanTask
Here are some examples from my domain for some of the Process.
<taskDefinitionId>default/SalesQuoteProcess!1.0/EnterQuote</taskDefinitionId>
<taskDefinitionId>Ravi1_Partition/CreditReviewRequestProcess!1.0/HumanTaskCreditRequestor1</taskDefinitionId>
<taskDefinitionId>Jegga1_Partition/HolidayProcess!1.0/StartNewHolidayTask</taskDefinitionId>
You already tried hardcoding it I guess and it worked. Now try generating them dynamically using simple String appenders and sort of properties file to make it more dynamic. How often do we really change partition name or human task name itself or name of process itself. They are pretty much fixed. Now comes only the Version number. This can change with your new deployment if you want to have different version. So just read all these from .properties file.
Thanks

Reusing Human Tasks across BPM Processes with different Data Objects

Hi
JDeveloper 11.1.1.6, WLS 10.3.6, SOA/BPM 11.1.1.6
I have defined 2 BPM Processes, P1 and P2, which has 2 different Process Data Objects O1 and O2.
But I am reusing the same Human Task in both the processes.
For the Human Task to support the activities in both the processes, I have added O1 and O2 Data Objects in the Human Task Definition.
And hence the ADF Taskflow / page generated out of the Human Task will have both the Data Objects O1 and O2 as payload objects in the Page.
When an instance of Process P1 is created, the payload O1 will have values, but O2 will be null.
And when an instance of Process P2 is created, the payload O2 will have values, but O1 will be null.
It works well like this, but I am a bit concerned about the performance from BPM Process and also ADF page.
In ADF page, let us say, somehow I can control the rendering of the attributes or creation of the iterator bindings based on identifying which process is being executed.
(By setting the iterator binding refresh property in page definition)
In this way attribute bindings for O1 will not be created when P2 is being executed.
But still when the Process instance is created, and when we see the payload structure of the human task in the EM - Audit Trail,
I still see both data objects O1 and O2 are created in the Payload, but O1 will have nulls in process P2.
So my question is, from performance point of view, is it advisable to define different Data Objects in reusable Human tasks ?
Or should I have to define a separate Human Task definition which contains only the Data Objects related to the process it is being called from ?
Thanks for any help

Martijn,
You are correct in your assessment that the JAG in the current JHeadstart release cannot cope with multiple bc4j packages. There is no work around for this. Upgrading to 9051 will not help.
In the JHeadstart-ADF release, this restriction has been lifted. You can place your EO, VO and AM objects in different packages, and you can group them in a separate project (Model project), while generating your JHeadstart application in a ViewController project.
We have a number of customers that use the latest JHeadstart-ADF builds to build their ADF apps. If you are interested in joining this beta program, please send an e-mail to [email protected]

Can Designer generate ADF Entity Objects, View Objects and Apps Module ?

Hi all,
On what way can Designer integrate with JDeveloper (+ ADF) ?
Can Designer generate ADF Entity Objects, View Objects and Apps Module ?
Thank you for your help,
xtanto

Designer itself has no direct integration with JDeveloper. However, there are three options. First of all, you can get a JDeveloper extension (download this separately) that lets you create a Connection to a Designer repository. From that Connection you can find modules that you defined in Designer and generate Entity and View objects for the tables and columns that you used in those modules, and an Application Module. It does not create JSPs or other user interface objects.
Another option is to buy JHeadstart from Oracle. This contains a set of code generators and ADF extensions that include an ability to get information from a Designer repository. JHeadstart works fine for non-Designer users too, but was built by the same people who wrote Designer Headstart - they know the repository API intimately.
The third option is to download Oracle Designer Extension Builder (ODEB) which was just recently made available. This is a product of a collaboration between Designer users from the Oracle Development Tools Users Group (ODTUG) and Oracle to extend the capabilities of Designer with user written tools and utilities. You could use ODEB to write your own generators for ADF Business Components. Or you could wait and see if someone else in the user community does this. I hope that you or whoever does such a generator will be willing to share it with us all.

Best practice for linking fields from multiple entity objects

I am currently transitioning from PHP to ADF. I'm looking for the best practice for linking data from multiple entity objects.
Example:
EO 'REQUESTS' has fields: req_id, name, dt, his_stat_id, her_stat_id
EO 'STATUSES' has fields: stat_id, short_txt_descr
'REQUESTS' is linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.his_status_id
'REQUESTS' is also linked to EO 'STATUSES' on: STATUSES.stat_id = REQUESTS.her_status_id
REQUESTS.his_status_id is independent of REQUESTS.her_status_id
When I create a VO for REQUESTS, I want to display: REQUESTS.name, REQUESTS.dt, STATUSES.short_txt_descr (for his_stat_id), STATUS.short_txt_descr (for her_stat_id)
What is the best practice for accomplishing this? It appears I could do it a few different ways:
1. Create the REQUESTS VO with a LOV for his_stat_id and her_stat_id
2. Create the REQUESTS VO with the join to STATUSES performed within the query for the VO. This would require joining on the STATUSES EO twice (his_stat_id, her_stat_id)
3. I just started reading about View Links - would that somehow do what I'm looking for?
I also need to be able to update his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr from a dropdown.
Any suggestions on how to approach such a stupidly simple task?
Using jDeveloper 11.1.2.2.0 if that makes a difference in the solution.
Thanks ahead of time,
CJ

CJ,
I vote for solution 1 as it's just your use case. As you said you what to update the his_status_id and her_status_id through the by selecting a STATUSES.short_txt_descr by a drop down. This is exactly the LOV solution.
ViewLinks are used fro master detail navigation (which you don't do here) and Joining the data make it difficult to update (and you still need a LOV for the drop down box.

Passing SQL Server identity attributes values into adf entity objects

Hi all.
I'm using Jdeveloper 10g for developing an ADF Swing application based on MS SQL Server DB.
Does anyone know if it is possible to pass SQL Server identity attributes values into the correspondent attrributes of adf entity objects, like we do with Oracle DB Sequence.
The problem is that i should somhow implement cascade deleting of detail view objects, so i should use the composition association. But since i cant fill the primary key attribute with appropriate value (that is actually a ms sql server db sequence value) i always get
the following exception: oracle.jbo.InvalidOwnerException: JBO-25030 as i try to create a new pair of master/detail objects.
Thanks in advance.
Alex.

The approach is good. but i still dont understand how i can address the sql server db sequence (identity field) programmatically...
The code offered
SequenceImpl sequence = new SequenceImpl("PRODUCTS_SEQ",getDBTransaction());
setProdId(sequence.getSequenceNumber());
generates something like this:
select deq_name.nextval from dual
but this syntax works for oracle only... and not for sql server...

Error while deleting a row from the Entity Object

Hi OAF Guys,
i am unable to delete the newly created row from the entity object.
let me explain my scenario.
1. i have a table of which some of the columns are mandatory.
2. I am writing the code in the validateEntity to check wether the user really enter anything into the fields.
3. My problem is, when the user creates row and wanted to delete the row without entering any details, the validate entity of the EO gets fired which will not allows to delete the row.
Is there any workaround for this problem.
Regards,
Nagesh Manda.

Hi Tapash,
I am very sorry for not providing you the complete details of my scenario. Here i am explaining
1. what code you have placed while creating the row and in validation method on EOImpl.
while creating a new row i am initializing the primary key of the EO with the sequence value.
2.When you say, you are unable to delete the row, are you getting a error message ? if yes, custom message or fwk error ?
its not the fwk error, its the custom message which wrote in my validateEntity method of EO to check whether the user had entered all the necesary columns or not.
3.How are you trying to delete the row ?
while the user clicks on the delete switcher i am getting the primary key of the row and searching for the row in the vo and finally deleting it.
The problem arises when the user creates a row, and later doesnt want to enter the details and delete it. Here while deleting the row the validateEntity method of the EO gets fired and doesnt allow me to do so :(.
Any way appreciate your help tapash.
Regards,
Nagesh Manda.

Crystal Report Print Engine API calls from Powerbuilder

I am using Crystal Report XI R2 with Powerbuilder 9.0. I am using Crystal Report API calls using crpe32.dll to display my reports. When i run my reports from my development machine where Crystal Reports is installed the reports run properly, but when i deploy my application on a server where Crystal Reports is not installed the report gives me error "Report has not been opened" , Error 599.
The database logon info is properly set in the RPT file.
I want to know whether it is possible to run reports without installing Crystal Reports and how do you do it?

Somehow, you will have to install the CR runtime...
Probably the best way will be to create a deployment project using a utility such as InstallShield, Wise, MS Visual Installer, etc. Use the RDC merge modules and add the crpe32.dll to the deployment project, ensuring the crpe32.dll is installed into the ...\3.5\bin directory. The Correct msm files are here:
https://smpdl.sap-ag.de/~sapidp/012002523100009381702008E/crxir2sp4_rdc_mm.zip
BTW., using the print engine APIs... Not something recommended, nor supported. Last header files for the crpe APIs shipped in version 9...

Add approval task through API call

Hello, I am attempting to solve the following problem.
I have a UDF defined on the Resource Objects form (OBJ table), this filed contains a comma delimited list of OIM groups which is of size n (based on the resource object).
I would like to create an approval task for each group in this list. In addition i would like the name of each task to show up as the group name. so when a user logs into the UI and looks at the approval details the see the approval task as the group name.
I have been able to add a task using tcProvisioningOperationsIntf.addProcessTaskInstance API however this API does not allow me to modify 1) the group to assign the request to and 2) the name of the task.
thanks

Hey Kevin, thanks for responding.
This query will allow me to get the process task key, so i can be added to the approval task via. tcProvisioningOperationsIntf.addProcessTaskInstance. However the issue is, no task currently exists. So before i can add an instance of the task i have to actually create a new task. but i was un-sure how to accomplish this through api calls.
The goal here is to allow a list of groups to be configurable at the resource level without having to modify the approval process.
thanks

Script Call from ADF

can we call unix Script (Bash script) from ADF?.
Is there any option of doing it ?

Should ADF Entity Object Map to Database Table or View?

We are building a new 3-tier JClient/ADF application. We have mapped most entity objects directly to database tables. Now that we are preparing to deploy, our DBA is angry; he believes that all entity objects should be mapped to database views. The developers see this as a headache, UML can not forward/reverse changes, and now we have another layer of abstraction, which doesn't seem to serve a useful purpose. What is the best practice in a new 3-tier application?

Hi,
I'm still having problems but I found out why these tables are returning errors. The username I've been given by the DBA to connect to the database is CONSULTA, but this user is only for querying purposes, the actual objects reside on a differente schema, of course, which is PROD. So the line:
"CONSULTA"."ESTADOS"@"PROD@AYADEV_LOCATION" "ESTADOS"
raises an exception because the table ESTADOS is not located on that schema, but on PROD. If I query the table from SQL Plus with:
SELECT *
FROM [email protected]@AYADEV_LOCATION
then there's no problem at all.
Why is this? How do I instruct OWB to point to the correct schema or to avoind fully qualifying the table name?
Please help me, I'm kind of confused here.
Best Regards,
--oswaldo.

ADF Entity Object

Is it true that
1) Against every request, for data, from the screen (ViewController UI), the data is fetched from the related Entity object only and no request is fired to the database at any level.
2) When both Application Server & database Server are up, Entity Object & the related database table are always completely synchronized (Whether data is changed manually directly at database level or through related ViewController UI).

Hi,

Multiple updateable adf entity objects

I've got a situation that is real similar to something that's covered in the developer's guide, yet it's just different enough that I need to get someone's help. I have a view object that is based on two entity objects. These 2 entity objects have a one to one association with each other. They both share the same primary key (hris_id). There is no foreign key relationship between them. This hris_id column for one of the entity objects has been set as a DBSequence type so that it's value can be set by a sequence. When i want to create a new row via this view object, I need to know where/when I can get this sequence generated value from the first entity object so that when the second entity row gets created, i can use this value (hris_id) from the first entity object to populate the hris_id column in the table for the "second" entity, since both tables will need to share the same value for hris_id column. Just not sure about where in the code this needs to happen. Any ideas? Thanks.

Hi,
I think your situation is similar as described in the guide.
Override create in your view object row class, create first and second entity and probably you need to copy key value from first to second entity.
Try this:
    @Override
    protected void create(AttributeList attributeList) {
        Entity1Impl newEntity1 = getEntity1();
        Entity2Impl newEntity2 = getEntity2();
        try {
            newEntity1.create(attributeList);
            oracle.jbo.domain.Number hrisId = newEntity1.getHrisId().getSequenceNumber();
            newEntity2.create(attributeList);
            newEntity2.setHrisId(hridId);
            .Rado

ADF Entity Object: Securable Operation "Create"?

Hello,
I have the following scenario: Within one view I have a table bound to a view object that bases on an entity object. The view also contains a "create insert" button.
Now I want to secure the "create insert" operation with a certain application role. However, within the entity object I can only activate the removeCurrentRow, read and update options as securable operation. Is there any way to control the creation of new items?

Michael
