Initiate a human task within worklist application

I got some questions regarding human task and worklist app
1. Is it possible to initiate a human task within worklist application? For example: jcooper initiate a request for expense straight from his worklist app
2. I see in jazn configuration. There is a bpm worklist view history role. Where do I access to history of all tasks already ended.
3. If a task is ended is it possible to bring it back alive?
Thank you in advance

Hi,
Check out the Java API that Oracle provides for the Worklist Application. It allows all sorts of customizations / task interactions. A good starting point is the BPEL Developer's Guide.
Enjoy, Sjoerd

Unable to initiate a Human Task after Wait

I am using Oracle BPEL Version 10.1.3.1.0.
Issue:
Human task throws an javax.naming.NameNotFoundException: java:comp/env/ejb/local/TaskServiceBean not found in ActivityManagerBean when it should initiate a Human Task Service.
Steps:
In Oracle BPEL workflow
1. Have a wait state for 30 seconds.
2. Have a Human Task created after that.
Expected result
Create an instance
Human task should be created after 30 seconds.
Actual results.
Exception is thrown
javax.naming.NameNotFoundException: java:comp/env/ejb/local/TaskServiceBean not found in ActivityManagerBean
If the wait condition is removed or time is set to 0, the error goes away.
Domain.log shows

<2007-05-04 12:00:13,421> <ERROR> <default.collaxa.cube.services> <::>
Please advise.

Yes, it works.
I can create task and see them in the worklist application.
Even if I put the time in wait to 0, it works.
It should be a very simple bug to reproduce. We have been able to do that on two different machines using these steps.
A wait of 30 seconds.
A human workflow task.
Initiate the process, it gives error. Remove the wait. It works.
Use a pick activity and provide timeout in onAlarm instead of wait approach. The same issue occurs.

Reassign human task using tasklist application...

Tasklist app have built in reassignment capability.
We tried to move javascritpt functions from TaskRouting.jsp to our auto generated human task from.
But when we want to reassign or delegate a task to other user fallowing error occurs.
An error occured while processing your request.
If you need more information, please check with your administrator with the following exception-identifier: "2007/12/13_05:49:32:375_jcooper"
After Succesyfull search using TaskRouting.jsp and turn back our form.
Then We can use our froms to reassign task.
succesifull request and unsucsyfull request's HTML's are identical. so w can't find source of this error
is there any one tried to make this.
Thansk for your help...

Human task notification after due date/expiration date/...

I would like to set a due date (or expiration date) to Human task, and set some notification before this time. Ok, it seemed very easy:
- i set due date to 5 minutes in human task -> Deadlines
- i set notifications in human task -> notification and in tab Advanced i set remind once 2 minutes before due date
Nothing happens. Exactly same (nothing) happens when i do the same with expiration date.
But what exactly is meaned under word "Reminder"?
It's mail? (then where I have to set email adress? I tried to set a "to" field in human task -> notification -> tab Advanced -> notif. header attributes => nothing happened)
It's worklist inbox message?
Or what ist "reminder" and how it should remind me?

Hi,
I don’t know if you’ve managed to resolve this issue yet and you mention you have emails working from BPEL, but I'm not sure if you've got any notifications working for the Human Task, if not then I have done some work with the human task notifications and although I’ve not tried to do what you’re doing, this is what I have learned.
Firstly to receive any notifications you need to configure the Messaging Driver and Workflow Notification Properties…
In Enterprise Manager expand [farm] -> SOA -> soa-infra
Right click soa-infra and choose SOA Administration -> Workflow Notification Properties
Underneath the page title (Workflow Notification Properties) is a note telling you to configure the Messaging Service Driver. Click the "Go to the Messaging Driver page" link.
In the associated drivers section you will have a single entry for soa_server1 (or what ever it's called for you). In the right hand column there is a button for configuring the driver, click this.
In the driver specific configuration, scroll down to OutgoingMailServer and enter the hostname or IP address of your mail server, then click Apply at the top of the screen.
Now go back to the Workflow Notification Properties screen and choose “Email” from the notification Mode and enter some sensible email addresses in the Notification Service section. It’s useful to have real email addresses in here at the moment because any failures will be returned to this address.
You now need to restart Weblogic for these changes to take affect.
After the restart you can test the notifications by doing the following
Back in Enterprise Manager expand [farm] -> SOA -> soa-infra
Right click soa-infra and choose Service Engines -> Human Workflow
Click on the Notification Management tab.
You can click the "Sent Test Notification" button to make sure everything is working ok. This screen also allows you to monitor notifications for failures.
Now that the notifications have been set up you can configure who gets notified on which events against your human task in JDeveloper.
The email addresses for the users are retrieved from your identify provider for the relevant user, by default this is the internal LDAP directory. I’m not using this, so I’m not sure exactly how this will work. There are options in the worklist application for individual users, but I’m not using this either.
Now that this is set up you can configure the human task within JDeveloper. On the notification tab you can decide who gets notified when. By default when a task is assigned to a user, the assignees are notified, you can play about with these settings to see what works best for you. Have a look at http://download.oracle.com/docs/cd/E12839_01/integration.1111/e10224/bp_workflow.htm#BABBHDGF for more information.
I’m not sure I’ve solved your problem, but I hope this at least helps.

WDA Human Task does not complete/close

Hi experts,
I'm still struggling to flex web dynpro abap and BPM together.
After embedding a wda chip as human task within my process, I face the next problem: The event defined as outport in my wda chip does not close the task when fired from my wda component controller. The page isn't affected by the event at all, the task is not completed. I debugged the wda method and found it throwing the event as expected.
Since the wda page is opened as expected and shows the data mapped via Input Mapping I think the chip and system landscape definition (done via the portal system administration) are correct.
Any clues on this? What am I missing?
Thanks and kind regards,
Helmut

Hello Abhilash,
thanks for your answer!
I created the event (wih one parameter) in the WDA componnt controller and the component interface and made sure it is thrown correctly (I checked it via debugger).
In the Chip I created an Outbound port (again with the parameter) and tagged it as CHIP_CONTRACT:PROCESS_STEP_END_POINT.
On the consuming side I did nothing special with the outbound event but mapping it's output to my process context.
Kind regards
Helmut

How to get the user logged at worklist (Adf Form - Human Task)

Hi,
I have an Adf Form Based on Human Task and and need to get the user logged at Worklist Application.
Anyone know to make this ?
Thanks.
Victor Jabur

Hi, thanks for your reply, but i discover a better way to make this:
public String getLoggedUserWorklist(){
String user = "";
try{
Map parameters=AdfFacesContext.getCurrentInstance().getPageFlowScope();
IWorkflowServiceClient wfSvcClient = WorkflowService.getWorkflowServiceClient();
ITaskQueryService queryService = wfSvcClient.getTaskQueryService();
String contextId = (String)parameters.get("bpmWorklistContext");
IWorkflowContext context = queryService.getWorkflowContext(contextId);
user = context.getUser();
}catch(Exception e){
user = "";
return user;
}

Customization of Human tasks the BPM Worklist App with ADF App

Hi All,
We are building a custom ADF application which aims to combine several business process human tasks to a unified interface.
And how to integrate the Human Task Flow BPM Worklist to my ADF App.
Otherthan that
To the BPM Worklist App we want to do customizations also like
1.Want to customize to apply our own custom skins to customize banner logo, title to the BPM Human Task Flow App.......
2.And based on the logged in user/role we wanted to restrict the features of the Work List App.
Say for Example should not provide the Facility to Add New Page if the logged in user is not an Admin, like wise no provision to add or modify or delete the Worklist Views like that...
How to get control the App based on User/Role
Any help or pointers would be appreciated!
I have ADF Experience from projects Using JDeveloper 11.1.1.5.
But, for me this is the first BPM case.
Renuka

Hi Renuka,
There are basically two ways to create an ADF UI for a BPM Task:
1. Generate it from the task
2. Create a ADF Taskflow based on Human Workflow Task
Since I tell this by heart, I might be slightly wrong in the terms.
You probably want to try the second option. It is accessible from the "New Gallery". You'll have to provide the Human Task from the BPM project, but then you can build up the ADF Taskflow by your self, based on the customizations of the rest of your application.
Should not be rocket science for someone with ADF11g experience. Since it is not my dayly job, I need to figure it out every time again ;). But I did it in the past and it wasn't so hard.

Martien

Participate in the same DB Transaction within Human Task Flow ADF screen.

Functionality:-
I have a ADF workflow screen generated from a Human Task flow, and for the business reason I run through the ADF Iterator and get the attribute values and persist within a table using an Application Module.
I am using the Application Module, and creating as below:-
String amDef = "model.TestAM";
String config = "AppModuleLocal";
TestAM service = (TestAM)Configuration.createRootApplicationModule(amDef,config);
Now, the issue is when I call the saving mechanism within the above AM client interface, it expects a commit, and this transaction doesnt participate in the same transaction as workflow process, so can anyone let me know how to get hold of the transaction handler and make this persistence to participate within the same one workflow transaction.
Cheers,
Saran.

Hi,
don't see how the transaction can be shared between the two. Any reason you don't use a DataControl for the ADF BC access and instead use client code creating a root application module?

Query on rendering the Human Tasks in the customized GUI application.

Hi All,
In oracle11g BPEL, Is there any way to render the Human Tasks in the Customized GUI (Weblogic Portal) application rather that using the applications like "Oracle BPM WorkList"?. Does the Oracle11g BPEL supports this ?. My requirement is that, i need to render the Human tasks inside my own GUI application. I do not want to allow the end user of my application to use the other GUI applications like Work List to wotk up on the human tasks. Instead of this, User must be able to access and work up on the BPEL human tasks through my Customized GUI (Weblogic Portal) application. Is there any way in Oracle11g BPEL to achieve the required functionality?.

Hi Naga
http://docs.oracle.com/cd/E14571_01/apirefs.1111/e10660/toc.htm
1. I would not recommend using APIs unless and otherwise if you do not have any other option. You can always create the TaskForms in your own custom pages using out of box generated bindings for each .TASK file. This gives more flexibility. There are lots of stuff associated with a Task apart from your own custom payload like full Task details, system attributes, headers, history, comments/attachments etc. You do not want to use APIs to get all these.
The below 2 links should give you an overview of overall architecture of a Workflow and TaskForms.

Re: deploying a large Oracle BPM Application with multiple UI projects
Re: What exactly 'PAYLOAD' Means???
Once you have basics covered, refer oracle docs also that shows how to reuse a single project.

Input information in worklist application's task details

Hi,
I want to show the input information to the approvers, in the task details of the worklist application
Can someone help me on this?
Regards

Pass the input information to the human task as a parameter.
Re-generate the simple task form or build a custom task form. This will give you a JSP that the worklist app will use to show the task data including the input data you provided.
For simple formatting I just create the simple task form and move things around on the JSP as needed.

Port used for task display form in Oracle BPM Worklist from SOA human task

My problem is that when I click on my task in worklist it is trying to show the task flow UI in a frame using port 7101 which is my admin server instead of port 7102 which is my SOA server where the task display form is actually deployed.
I have an admin server running on port 7101 and a managed server with SOA configured running on port 7102. My application contains a soa composite project and a task flow project that was auto-generated from the human task in my composite. The applications deploys successfully to the soa server and I can run my BPEL process successfully and see the task show up in worklist.
I have modified hwtaskflow.xml with this:
<TaskFlowServer>
<hostName>localhost</hostName>
<httpPort>7102</httpPort>
<httpsPort>8002</httpsPort>
</TaskFlowServer>
I access worklist at: http://localhost:7102/integration/worklistapp/
But when I click on my task in worklist, the task display form is being referenced at
http://<ip address>:7101/workflow/VacationRequestTaskFlow/faces......
instead of
http://localhost:7102/workflow/VacationRequestTaskFlow/faces......
Any ideas? After changing hwtaskflow.xml I redeployed and restarted everything and it still doesn't work.
Edited by: Billy Turchin on Oct 1, 2009 12:43 PM

Actually my config.xml does not have have two soa_server1 entries ... it has only two <server> entries but each one also has an SSL entry; see below. (This was not done by me BTW, but rather when I ran the domain configuration wizard)
I don't think the problem has to do with the SSL entries, because those ports are not getting used. The default port for my human task is 7101 (DefaultServer) instead of 7102 (soa_server1). Once I changed the port using the EM it seems to remember it when I deploy new revistions of that composite but anytime I deploy a new composite for the first time, the port for the task display form is incorrectly set to 7101.
How exactly does worklist determine which port and URI to use for a human task's display form? Does it iterate through all the registered task display forms to find one that is registered for the given human task? (ie its not a property of the human task itself, but rather a property of the registered ADF display forms).
<server>
--<name>DefaultServer</name>
--<ssl>
----<name>soa_server1</name>
----<listen-port>8001</listen-port>
--</ssl>
--<machine>LocalMachine</machine>
--<listen-port>7101</listen-port>
--<listen-address></listen-address>
--<tunneling-enabled>true</tunneling-enabled>
</server>
<server>
--<name>soa_server1</name>
--<ssl>
----<name>soa_server1</name>
----<listen-port>8002</listen-port>
--</ssl>
--<machine>LocalMachine</machine>
--<listen-port>7102</listen-port>
--<listen-address></listen-address>
</server>
Thanks for the replies thus far...

Adding custom properties to a human task of a worklist

How can I add custom properties to a human task of a worklist. I don't know if it is possible. I tried to read the oracle BPEL Process Manager Workflow Services API Reference, but this is unreadable :-). Classes, Methods and Parameters are not commented...
Moreover where can I find a GOOD description of the Workflow Services API explaining the usage of the classes, methods and their associated parameters ?
Regards. Yvan

I means I would like to add some parameters to the task without having to load the payload. I would like for example to use these parameters to do query on worklist. Or may be there is also a mean to do search query on worklist using some values that are into the payload of the tasks. May be you can help me :-)
Regarding the documentation of the worklist API, it is for me very difficult to understant the role of the method as for example SystemMessageAttributesType.setTextAttribute1() or SystemMessageAttributesType.setNumberAttribute1() and so on, if there is no javadoc available and it is the same thing for all methods of the API :-).
Definitivly I would like to understand the Task entities and all available properties and action I can apply to it to know excatly what I can do with it. Where can I find this information ?
Regards. Yvan

How BPEL refers to human task form application during runtime ?

Hi All,
I have worked on coulple of 10g BPEL human tasks and I remember '.tform' file used to capture
task display jsp application url
content of tform file
<template>${http_url}/${domain_id}/BPEL_PROCESS/1.0/Task Form/Task Form.jsp</template>
I am looking for help on how same is achieved in 11g
in Nutshell,
How does 11g bpel knows which task form it has to invoke?
Thanks,
Praveen

Hi Praveen
If you already have a bpm/bpel application in soa 11g, open that in JDeveloper and serach for the file named hwtaskflow.xml. This file will be under your taskforms project -> Application Sources.
In JDev, for each human task, there is a .task file generated with payload details, actions that task is allowed etc. We can generate taskform for this .task using autogenerte or custom. Either way the above file will have the details like the association of the actual Task and correspond taskform jspx file. If you are familiar with the ADF architecture like bindings you can understand much better.
In EM console, click on the workflow file that is deployed under your soa_doamin. On right side, you will see list of all the human tasks and click on any human task. You will see the uri for that task. This is the reference for the deployed composite for that task. Now the above .xml file will have the exact human task name with additional information like which pageflow defintion file to invoke. All the pageflows xml files are under your taskforms\web-inf folder.
See the below link for more details:
http://download.oracle.com/docs/cd/E21764_01/integration.1111/e10224/bp_designtf.htm#CHDIFHIJ
see the section named "28.3.3 What Happens When You Create an ADF Task Flow Based on a Human Task".

Initiate Human Task from Mediator

Hello,
In SOA Suite 11g, I'm calling a human task from a mediator. How do I pass the input value for the mediator as a parameter for the human task? In other words, how do I assign the input for the mediator to a parameter defined in the human task?
I've been looking for examples, posts, and documentation on how to do this. I can't seem to find any examples. Am I missing something?
Thanks

I found that initiating a human task from a mediator does not work well. I ended up changing the process to initiate the human workflow from a bpel process. It now works very well.
