Human Workflow in BPEL

Hi,
We are able to get the users(participants) from an ADFbc service Response variable.But,how do we need to assign these users as participants in the Human WorkFlow(inside the Nflow).Depending on N , the users retrieved would be different for each flow in Nflow.
We have tried to assign the foll:
<copy>
<from variable="Invoke_3_getUsers_OutputVariable"
part="parameters" query="/ns2:getUsersResponse/ns2:result"/>
<to variable="initiateTaskInput" part="payload" query="/taskservice:initiateTask/ns5:routingSlip/ns5:participants/ns5:participant"/>
</copy>
but getting some fault as "Invalid service input element". I tried to assign this output variable to task assignees as well..but dint work
Any pointers would help..
thanks in advance
Regards

Ronald,
By cancel means i need the worklist entry for the given taskid to be deleted or marked as cancel so that the user will not be able to process the task. The BPEL process should have a human task process defined like updatetask which will cancel the task.
Let me expalin our scenario.
We have an assignment which has different status like new,reassign,cancel. Using a switch we check for the required status and if the status is new we call the initaiate task. Similarly if the status is cancel we need to cancel or delete the task for the user.

BPEL Human Workflow:IWorklistContext

Hi,
I am trying to access the tasks assigned to perticular user using Human Workflow APIs, but I am unable to get the task list eventhough tasks are assigned for the user. I am using below mention code,
RemoteWorklistServiceClient client= new RemoteWorklistServiceClient();
client.init();
String user = "dlsdeomgr";
String password = "welcome1";
//client.
IWorklistContext ctx = client.authenticateUser(user, password);
Map filterMap = new HashMap();
filterMap.put(IWorklistService.FILTER_TYPE_TASK_FILTER,IWorklistService.TASK_FILTER_MY);
filterMap.put(IWorklistService.FILTER_TYPE_STATUS_FILTER, IWorklistService.STATUS_FILTER_ASSIGNED);
String keywords="";
List tasks = client.getWorklistTasks(ctx,filterMap, keywords,
IWorklistService.SORT_FIELD_TASK_TITLE,

Task task = (Task) tasks.get(i);
String taskId = task.getTaskId();
String status= task.getStatus();
System.out.println("Task ID!!"+ taskId + "status" +status);
let me know if I am doing wrong? or is there any other way I can access asynchronous bpel process using human workflow API. Thanks

Oracle Content Services + BPEL for Human Workflow

Greetings,
I'm new to Oracle Collaboration Suite and BPEL. I'm starting to work with this technologies.
My goal is to develop some custom human workflow using Oracle Content Services 10.1.2.3.0 and BPEL.
Regarding software versions, some doubts arise ... I'm using Collaboration Suite 10.1.2.
- Which version of SOA Suite (10.1.2 or 10.1.3.1) and BPEL are recomended to work with content services 10.1.2.3.0 ?
Thanks,

The certified version for Content DB/Content Services 10.1.2.3 is 10.1.2 of BPEL.

Differences in Oracle Service Bus, BPEL and human workflow

Hi Everyone,
I am newbie, don't know if its the right place to post this thread.
I want to prepare paper on differences in Oracle Service Bus, BPEL and human workflow, can anybody help me.
Till now i came to know all these things are very different, no poit comparing them but still need differences
Thanks in advance:
Vikas

Basic difference:
BPEL : It is used for orchastrating different processes. Its heavyweight and stores instances (stateful)
OSB : It is used for routing data between the applications
Human Workflow : It is used to handle scenarios where manual intervention is necessary.

Cancel Task in BPEL human workflow

All,
We have a requirement to cancel the task for the user using human work flow. The worklist should be deleted for the user. Let me know if oracle human workflow provides an opertaion option to cancel the task like reassign,initaiate etc.

BPEL Human Workflow - dynamic Outcomes

Hello All,
While designing human task, I can pretty much provide XPATH everywhere, but I couldn't provide xpath for outcomes.
Is it possible to provide dymanic outcomes?
- I am not sure how does Worklist App figures out set of outcomes, I didn't it as part of task input.
I appreciate your help.
Thanks,
Chintan

Alright, it is certainly getting interesting to me, and would really appreciate if somebody provide any insight to this issue.
- I saw that TaskLink input (initialTaskInput), does have property called parallelOutcomeCount in systemAttributes, which decides type of outcomes to worklist application.
q.1: Why I am not able to override this attribute (parallelOutcomeCount )? I tried to put my own value right before the INVOKE operation, still it didn't work, it got over-ridden by BPEL engine?
q.2: I don't see any ASSIGN activity to assign parallelOutcomeCount, I do see assign activity for assign system and payload activity generated during Human Workflow. How do they get set? Is there is any interceptor concept?
Really curious, because it there is any hidden way to set such variable, I would love to use such framework for many different purposes.
Thanks!

Exposing BPEL Human Workflow Activities in ADF

Hi All,
I want to have a clear idea on best practices/ ways on
"How to expose BPEL human workflow processes in ADF".
Do I need to create an ADF application where I can consume BPEL datacontrol.
or Do I need to manage ADF datacontrols with BPEL databases and create VO EO and create datacontrol.
What could be the best practice on exposing BPEL Human workflow in ADF.
Waiting for reply.
Regards,
Hoque

Hi Hoque,
you can create direct an ADF Task Form Projekt from your HumanTask Wizard. Cehck out this two links:
Implementing an Oracle ADF Task Flow for a Human Task - 11g Release 1 (11.1.3)
http://docs.oracle.com/cd/E28271_01/dev.1111/e10224/bp_tutorialhwf_.htm
Never access the SOA Suite databases directly, it is a bad practice.

Issue in passing payload from Human Workflow to ADF task flow

Hi All,l
I am facing one strange issue in Human Workflow -> ADF task form integration. I have 4 Data variables to pass to the task form for displaying and modifying the request payload. E.g
1. request
2. propertiesList
3. input1
4. input2
request and properties list variables are in the same namespace. When the process is executed, I can see the data being passed in Initiate taskflow activity in BPEL. However I don't see the data in ADF form only for propertiesList variable. This is a custom schema element I added newly in the project. I don't get any error , but no data is getting displayed.
Any help in this matter is greatly appreciated.
Thanks
Ashwini

I have applied workaround for this. However the main issue still exist.
When I pass hard-coded values in the list and drag and drop that list as selectOneChoice - I see the values in dropdown. Whereas, when the list is passed from program logic and I can see the values passed in initiateTask activity, and drag and drop the field as selectOneChoice, the values don't come up.
I will replicate this issue in a smaller piece of code and paste here later.
Thanks
Ashwini

Issue in Human Workflow

Currently I am learning Human Workflow integration in Oracle BPEL.
http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_introhwf.htm#BABIEDCJ
I have used this URL to see tutorial accordingly I created BPEL process but when I am testing this BPEL process I am able to do raise a request but now able to see that request in manager's Queue.
Can anybody help in this?
Thanks,
Yashwant

Hello Yashwant,
The tutorial seems fine, but as you might´ve noticed the manager assignment depends on information received in the message inbound, maybe if you post your request body we can take a further look into it. Maybe your XPath is not correct? Maybe namespaces don´t match? I´d start from there...
Thank you,
Vinicius

Hi Experts,
I working on a Human Workflow Project in SOA Suite 11.1.1.6.

Can we even have the following landscape?
1. HSS,OHS,Weblogic server,workspace - On a Windows 2008 server
2. Essbase server,EIS server,EAS server,EIS server - on a Linux server
3. Oracle database on another linux server.
my questions is, can we have the installation and configuration done considering the OS (wid and Linux), as described in points 1&2 above.
I guess I read somewhere, that all the web applications can be deployed to either all windows or to all Linux OS servers? - Is it correct?

Human workflow in catch construct

Hi,
I have a requirement that , whenever business fault occurs I want to throw it explicitly. In catch block, I want to catch it , and I want to have a human workflow activity with updatable payload.
when i am trying to do this, i got following error while compileing....
Error(228):
[Error ORABPEL-10051]: multiple create instance activity
[Description]: in line 228 of "D:\BPEL\source\samples\tutorials\107.Exceptions\Application1\FaultHandlingDemo\PayLoad\bpel\PayLoad.bpel", Conflicting createInstacne="yes". Instance is already created by another activity.
[Potential fix]: Remove createInstance="yes" attribute from this activity.
can we have a human workflow activity inside catch construct?
why this error is coming? can anyone pleace help me....
thanks

Hi,
Your scenario is possible. We have similar processes. It seems the error is caused by a BPEL activity in your process that has the createInstance parameter set to yes while the instance is already started.

Configure DB connections used by Human workflow

Hi All
We are using Oracle BPEL for orchestrating a process flow; the BPEL process uses Human workflow service for assigning tasks to users and Java client code(SOAP client) is used to update tasks assigned to users.(we are not using Worklist application). The users are updating the tasks using the java client code and this is a continuos process.i.e. users work continuosly in shifts.
The workflow service seems to utilize lot of DB resources as 50-60 users are working continuously at the same time... Though we can configured the DB parameters/connection pool we are having some performance issues..
Just wondering if we can have a seperate connection pool/data source for Human workflow service?? Then orabpel application and workflow service can use seperate pools and the load can be reduced..
Any documentation/pointers on this will be of great help on this...
Thanks

You can / should have your HW app in a different, database, at least schema. Then it is just a matter of setting up a differnt connection pool for the HW app.
There is also noting stopping you from having 2 different connection pools pointing to the same oracle schema. One for HW and one for bpel. They can be tuned accordingly.
cheers

10.1.2. to 10.1.3 Human workflow task migration issue

Hi all,
I am currently looking at the possibility to migrate our 10.1.2 bpel processes, containing human workflow task, to 10.1.3.1.0 Everything seems to migrate smoothly except the human workflow functionality.
The initateTask invoke action returns the following error in the 10.1.3.1 console when I ran an 10.1.2. bpel process containing a human workflow task:
[2006/12/04 03:01:00]

I know that in 10.1.3 the human workflow mechanism is heavily changed and now is invoked by using other services (TaskService) than the services used (TaskActionHandler process)in 10.1.2. In 10.1.2 the TaskActionHandler was a separate build-in bpel process used for interaction between a bpel process and the human workflow. This process is not present in the 10.1.3.1 installation, so that is causing my error. Moreover, in 10.1.3 the interaction between a bpel process is and the human workflow is not done by invoking a separate bpel process (TaskActionHandler) but by invoking a java wsif service TaskService..(Correct me when I'm wrong or not complete)
My question now is how can I migrate my 10.1.2 human workflow task to 10.1.3.1 without manually rewrite the task scopes to 10.1.3...According to the fragment below copied from the JDeveloper 10.1.3.1 help files it should be possible. Maybe, there's is a way to deploy the needed processes manually?

This editor enables you to specify task settings such as task outcome, payload structure, task participants, assignment and routing policy, expiration and escalation policy, notification settings, and so on. You cannot use the Human Task editor to edit 10.1.2-based workflows. To use any new 10.1.3.1.0 functionality, the task scope of the workflow must be manually migrated to use the new workflow metadata. Note also that this is the last release in which you can deploy workflows designed with 10.1.2.
Kind regards,

Hi Clemens,
Thanks for your quick response. The Taskmanager and the Taskactionhandler are indeed not deployed so I will do that automatically.
Still one question/remark left:
You noticed that you still have to complete the tasks using the old worklist app. . So if i'm correct, you have to use the deprecated 10.1.2 worklist api or build-in worklist app. The 10.1.2 worklist app is not deployed in my 10.1.3 installation. However, 10.1.3 only contains the new worklist app. Is there also a way to deploy it manually?
Writing this down it al looks a bit clumsy to me. Is it not a better option to invest some time in migrating all tasks scopes manually to 10.1.3, because as far as I can see the human tasks are causing the main issues concerning migration? After this you have a 10.1.3 compliant system. I wonder what your opinion is on this issue.
Kind regards,
Tom

Hi Philippe
Yes, almost all the APIs should work fine for BPEL or BPMN. Because most of times whether its BPEL or BPMN, they both end up having the same standard components like HumanTasks, Taks, Processes, NotificationServices etc. The concept of TaskList and Tasks is same. So almost all the standard Task, Workflow APIs etc should work. We use BPM Process and use the same APIs to manipulate tasks using APIs. They work fine.
Now specific to BPMN, there may be some more APIs say for example only BPM has something called like Dashboards, more powerfule BusinessRules, DataObjects, ProcessDataObjects etc etc. I guess Oracle may not yet published public APIs specific for BPM APIs. I have not seen so far.
Here is the link for 11.5 Version APIs for all the areas: http://docs.oracle.com/cd/E21764_01/ref.htm (Oracle SOA Suite API Reference will have all soa related APIs).
