Human Task
Hello,
we have humantask in oracle soa 11g
problem is : if say a user claims a task and does not act upon it after claiming and go on vacation.
now the task he has claimed is nit visible to other users in bpm worklist. so as long as he is on vacation, we have no way to act on that task since it is already claimed by him and is just not visible for other users.
How to solve this problem ?
we want some other user be able to SEE his task even when he has claimed and GONE on vacation without acting on it.
pl tell us, what we need to do step by step, so that some other user can act on such claimed (and unacted upon) task ?
thx
D
Couple of options I can think of.
1) Instead of having manual claim, you can use auto-claim feature. Below the option that goes into workflowConfiguration tag of .task file.
<enableAutoClaim>true</enableAutoClaim>
Worklist -> Adminstration -> Task Configuration -> Select Task -> Event Driven. You can see this option.
2) BPM Administrator or Task owner can manually release the task from Worklist -> Administrative tasks tab -> Actions -> Release.
3) Before vacation, the person who claimed the task can manually release the hold by using Actions -> Release menu option on worklist. This is manual.

Invoking Web Service from BPEL PM Human Task
Hello,
I have done the following tasks
Create a BPel PM , Add a Human task and customized it.
Create a Web service Proxy and Generate a Jar File from that classes like "wsCallRegions.jar".
First issue : Where can i put my Jar File ? i don't have any WEB-INF\lib directories to add this Jar to my Webcontent on the human Task.
Second Issue : I imported the library and all dependencies Using Jdev / import Libraries tool. But when i try to call this Web service in my Paylod-body.jsp say it does´t find the class of WS that i´m using ( I can rebuild it with no errors and deploy it to the server ), this just happen when load the payload-body.jsp page customized.
How can i make my ant deployment description to load a Lib directories or add this jar to my human task customized ??
can somebody help me please ?
Many Thank,
VitorThe problem is that now, with Weblogic Server the project is divided in two...
And the import goes with the BPEL.JAR and not with EAR files to Weblogic SoaDomain.
Someone knows where I can find some documentation about this issue ? This maybe could be a "bug" when deploying Human Tasks to Weblogic Appserver ?

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> -
Unable to deploy BPM projects with human tasks from BPC
I’m trying to edit and deploy a BPM process from Business Process Composer (web based tool). To do it, I followed the steps below:
1. I created I project in JDeveloper
2. I created the Human task from using the “Auto-generate task form” option
3. I converted it to a template
4. I published it to BPM MDS
5. On Business Process Composer I created I new project based on my published template
6. And I finally I deployed it with no errors.
When I ran the BPM it creates I human task but I’m not able to access its form on Business Process Workspace.
On Business Process Workspace I can see the task created by my BPM process, but when I click on it to access its form I get a 404 message (message below).
Error 404--Not Found
From RFC 2068 Hypertext Transfer Protocol -- HTTP/1.1:
10.4.5 404 Not Found
The server has not found anything matching the Request-URI. No indication is given of whether the condition is temporary or permanent.
If the server does not wish to make this information available to the client, the status code 403 (Forbidden) can be used instead. The 410 (Gone) status code SHOULD be used if the server knows, through some internally configurable mechanism, that an old resource is permanently unavailable and has no forwarding address.
I think this error occur because my Task form project was not deployed. To fix it I undeployed all the applications and then I deployed the BPM application with all its tasks forms from JDeveloper. It worked fine (I can actually access the task form on Business Process Workspace), but now I’m not able to edit the BPM process on Business Process Composer anymore.
Then I finally repeated the steps 3 to 6 on top of this post in order to make the BMP process editable on Business Process Workspace but this time I receive the error at the end of this post taken from server log.
No matters if I publish the project on MDS BMP repository as a template project or as non template project. I always have the same problem.
So, how can I use a BPM project that contains Human Tasks forms on Business Process Composer?
I’m using:

Firstly, you shouldn't deploy QuoteProcessLab with other UILabs like ApproveDealUILab and so on. So, if you already did it, then go to Weblogic EM and undeploy it.
Secondly, you should deploy each of UILab separately as standalone application. So, deploy EnterQuiteUILab, BUsinessPracticesUILab, and so on each. These will run independently behind and when your project created based on template in the Composer runs, it will link each of these on human task.
Thirdly, publish you QuoteProcessLab. And follow the book about how to create a project based on template in the Composer.
Just one thing you should be careful with is, when you do auto-generation for human task, it sometimes doesn't work fully, unfinished halfway through. So, make sure that the icon 'go to existing business form taskflow' in .task file takes you to the human taskflow.
If it fails, do another auto-generation. Sometimes DataBindings.cpx can get corrupted by JDev, but let's not go too far for now.
Mostly, it will work.

How to open and navigate between human task forms in a same page?
Hi
I use Oracle BPM 11.1.1.5
I have a question about taskflows in BPM Application.
In ADF web application, I create a sipmle task flow and insert view id and bind these to jspx pages, my pages are opend in same page when
return an outcome.
For exapmle I have three pages like A,B,C.
In task flow, insert three view ids and bind to A,B,C.
My first pages is A, and when outcome is B navigate to B, when my outcome is C then navigate to C in a same page not separate pages.
But my problem is here.. in BPM Application when create task forms, every task has a separate task flow that there exist a single view id and a wild card flow in it.
In BPM workspace when initiate human task form is closed, I should press refresh button to see next human task form in task list table.
I tried to create a simple task flow and insert human task forms in it and navigate between these.. but show human task form in wrong display and don`t show some component and human task payload.
Now, my question : How to open and navigate between human task forms in a same page like software installation?Having a separate Data Control for each human task is normally the case. There is a way to assign multiple human tasks to a single data control (and one task flow), but I don't think that this is going to help you with what I think you're trying to do.
If your human task is called "EmployeeDetail", then you'd use the data control associated with this for the UI pages in the task flow diagram that is associated with this human task. For example, you might have a first page that has just the basic employee information - the fields (at least the ID field) would come from the EmployeeDetail data control. When the end user clicks "Next", you might have this UI page flow to a second UI page in the task flow diagram that has the employee's address information. You might place the address fields from the EmployeeDetail data control onto this second UI page.
You might be asking how the work item instance can automatically flow to the next interactive activity in the process while staying inside the first interactive activity's human task's task flow diagram. This is not how it works - the task flow diagram models the end user interaction while inside a single human task that is tied to a specific interactive activity in the process. If you want a the end user to be able to move the instance through multiple interactive activities in the process in one interaction, look at "Activity Guides". Activity Guides do a nice job of this.

ADF forms based on BPM human tasks - Invoking webservices/view objects.
Hi All,
Is anyone aware of whether the following is a valid implementation that has been carried out before.
1. ADF forms based on BPM 11G human tasks.
2.The ADF forms invoke webservices via Webservice data controls. It is pertinent to note that the webservice bring back complex data types. We've tried writing a few forms, resulting in data benig brought back, but not being able to print them to the screen.
3. The ADF forms also use View Object based on sql to bring back tables of data. If view objects are embedded within the forms, the applciation gives rise to a null pointer exception.
Considering the form will be invoked via a BPM worklist entry, is there a setting or configuration we should consider before hand. Is this feasible, is there knowledge of this being done commercially.
Any examples or information regarding the same will be immensely helpful.
Thanks and Regards,
Preethi.
NB : I have posted this in the BPM forum as well as I feel it is relevant to both BPM and ADF.Hi Joonas.
Plese let me explain me better for your understanding
A big summary for what I meant it's the following:
1- In the procces you made, when you add the HT activity, you have to implement it, this means declare the input(s) parameters you want. This implementation create the .task file.
2- Create an application, and projects as HT you have. Each poject are based on the .task file, and automatically create a Data Control (for each project based on a .task) with all you need.
This w'll be an empty application, so you can customize it all you want. The task selected should have all the parameters previously defined. Those parameters can change if you want.
2- Create a page(s) in the task flow for the task implementation. You can even split the the payload of the task in differents pages, create your custom pages and any logic you need.
3- An important aspect is how to match these application with the HT implemented in the process. It's possible, it's a configuration en the Enterprise Manager.
4- Deploy your application
All these are explain in the book I mentioned

Not able to access human task form (11.1.1.4)
I installed SOA Suite with BPM Suite 11.1.1.4. I ran into quite a few issues. The biggest one is I am not able to access the human task form in BPM workspace even for the new application created in 11.1.14.
Do you have such issue? I am not sure if it is a bug or is related to my specific installation. I followed the document “Quick Start Guide for Oracle® SOA Suite 11gR1 (11.1.1.4.0) Version 1.6” for the installation. The only difference is that I installed the generic version of WebLogic and JDev and configured them to use JDK 64-bit version since my OS is windows 7 (64-bit). Before, I had installed 11.1.1.3 with 64-bit and it was working fine. The only tool installed with 32-bit is the JDev 11.1.1.3. Since JDev 11.1.1.4 is supporting 64-bit, I installed everything with 64-bit for this time.
The details of the error are the following:
With JDev 11.1.1.4, I created a new application which has a simple BPM process with 3 flow objects: start event-user activity-end event. The human task has the auto-generated task form. I deployed the application to the SOA server.
When testing the application, the task was created and listed in the BPM workspace. But when I clicked the task link to open the task form, the web page was hanging. I noticed the following log was REPEATED again and again in the access.log:
140.98.125.168 - - [20/Apr/2011:10:28:08 -0400] "GET /workflow/TestpsUI/faces/adf.task-flow?bpmWorklistTaskId=2a5b4ad1-823f-4615-8a7e-c5449a7be814&bpmWorklistContext=12aa4934-991a-487c-b7f3-5159808c399a%3B%3BtbcZXSd1E1LVZv8OIaLZGd21meLUMNkYSMsmz60kNKoEaJ1N53wy3zyRYA%2BunyKF9UNi50fPHKtaXY6IqKbh%2Fu68WebTan3zCwGsUNmNMaw8aLEygS5qb2cOGx2qGal86F%2FgiRka874PYLXhohFdDPCQyoxre2p7IgpsloLHq2rh7T3zWGnyOjLdC7Qw0Geb20Kfp8XA2UUIoxaxTHS6YFPQqqs%2FzIkyEsgMNQJMDbYYGdceRL2sT8rMkBXpmQ0r&bpmWorklistHttpURL=http%3A%2F%2Flocalhost%3A7001%2Fbpm%2Fworkspace%2Ffaces&bpmWorklistHome=home.jspx&bpmWorklistReassign=reassignTask.jspx&bpmWorklistRoute=routeTask.jspx&bpmWorklistRequestInfo=requestInfo.jspx&bpmWorklistSecurity=signTask.jspx&tz=America%2FNew_York&lg=en&cy=US&vr=&dispNameLg=en&dispNameCy=US&dispNameVr=&df=medium&dt=both&tf=short&bpmWorklistSessionTimeoutInterval=900&soaUrl=http%3A%2F%2F140.98.125.168%3A7001&bpmBrowserWindowStatus=taskFlowReturn&adf.tfDoc=%2FWEB-INF%2FHumantask_TaskFlow.xml&adf.tfId=Humantask_TaskFlow&_task-flow-return=http%3A%2F%2Flocalhost%3A7001%2Fbpm%2Fworkspace%2Ffaces%2Fadf.task-flow-return%3F_adf.ctrl-state%3De1i6yi1gq_35&_adf.winId=e1i6yi1gq_26&_afrLoop=7156779026094&_afrWindowMode=0&_afrWindowId=null HTTP/1.1" 200 5478
Please help if you know what is going on for the issue.
Thanks a lot,
HelenGo to OEM, select the SOA Composite application you deployed.
Under Component Metrics … click the link of the Human Workflow Component that you have the issue
The settings of the Human Workflow Component would be displayed
Click the Administration tab, you will get the URI setting for the human task
update the Host name etc. as you want and click "OK" then click "Apply"
Please note: this is just a shortcut for my own dev-env. I have not got the time to figure out why this happens. It is sure not the right solution for the production if we have the issue in the prod-env, I think. -
Display the status of parallel human tasks in ADF web page (BPM 11g)
Hi,
We create a BPMN process (BPM 11g) which splits into parallel branches. Each branch has its own user activity. We want to show the task status of ALL the parallel user activities (running or completed) in the ADF web page implemented for the user activity so the user would have the whole picture of the process.
In another words, we are able to check the status of the component instances associated with the process instance in the Oracle EM. We want to provide the similar information (in our case, we only want to show the status of the human task components) to the user when they access the human task page.
I wonder if the only solution is to write Java code with the API to lookup the BPMN process instance. We try to avoid Java coding if possible. Please advise. Also, so far, I have not found any complete instruction/document on how to access the BPMN process instance and check the tasks etc. through the API. Please help if you know where I could get such information.
Thanks a lot,
Helensorry!!

Hello,
I have a really simple process which includes a create entity activity. It works perfectly fine as data is inserted into the table and i can see everything is completed in the flow trace. Now, when i insert a human task after the create entity activity, things start going wrong. While i don't see any errors in the flow trace and all tasks are completed as planned, the BPEL component's state is showing as running and at the end of the flow i got the message "The transaction was rolled back. The work performed for bpel instance "123456" was rolled back to the previous dehydration point, but the audit trail has been saved...." It seems like it's waiting for something from the human task (even though it was completed successfully). As long as I leave this running, the process would try everyday from 12:00 AM to 4:00 AM every five minutes. That's another issue that i can't figure out. Can someone shed some light on this? Thank you.Hi,
its best to post this question to the SOA forum. The answer on this forum would be to use a page template, a parametrized bounded task flow and then add the bounded task flow to each page that has the template. However, the task flow in the HT case is generated, which means that you re-build it all the time (meaning you don't work with the same task flow but multiple). If you know how to just use the HT API to access the information to display, you could write a generic bounded task flow for this. Check on the SOA forum if they can come up with a template approach for your use case.

Human tasks, complex types and variable assignment.
Hi folks,
I encountered a problem while working with 10.1.3.1 which I haven't managed to solve yet and would be grateful for assistance. I have defined a complex data type (just a sequence of strings) and want to fill that data type by going through a flow of screens, e.g. through several human tasks. I have defined that type as a variable to the BPEL process and have managed to assign simple expressions to the variable and pass that into a Human Task. In the task I see now a simple input form for all attributes of the type.
Now the problem. After I fill out the form and complete the human task, I have
The global variable:
<outputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<MyProcessResponse xmlns="http://xmlns.oracle.com/VacationRequest">
<vorname/>
<nachname/>
<strasse/>
<nummer/>
<postleitzahl/>
<stadt/>
<maximaleDauer/>
<minimaleDauer/>
</MyProcessResponse>
</part>
</outputVariable>
and the return value from the human task:
<task>
<title>CaptureData</title>-
<payload>
<MyProcessResponse>
<vorname>David</vorname>
<nachname>Beckham</nachname>
<strasse>HighStreet</strasse>
<nummer/>
<postleitzahl/>
<stadt/>
<maximaleDauer/>
<minimaleDauer/>
</MyProcessResponse>
</payload>
</task>
Now the only thing I would like to do is to replace the original values in the variable with the new values that have been returned from the task, this should be performed in an extra assign step. Sounds simple. JDeveloper wouldn't even let me klick through the return value from the HumanTask, so it seems as if I have to do things manually.
These are my tries:
Command 1:
<copy>
<from variable="CaptureData_1_globalVariable"
part="payload" query="/task:task/task:payload" />
<to variable="outputVariable" part="payload"
query="/ns1:MyProcessResponse"/>
</copy>
Result 1:
<outputVariable>

<nummer/>
<postleitzahl/>
<stadt/>
<maximaleDauer/>
<minimaleDauer/>
</MyProcessResponse>
</ns0:MyProcessResponse>
</part>
</outputVariable>
--> There is one MyProcessResponse element too many
Command 2:
<copy>
<from variable="CaptureData_1_globalVariable"
part="payload" query="/task:task/task:payload"/>
<to variable="outputVariable" part="payload"
query="/ns1:MyProcessResponse/ns1:vorname"/>
</copy>
Result 2:
<outputVariable>
<part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload">
<MyProcessResponse xmlns="http://xmlns.oracle.com/VacationRequest">
<ns0:vorname xmlns="http://xmlns.oracle.com/bpel/workflow/task" xmlns:ns0="http://xmlns.oracle.com/VacationRequest">

<nachname/>
<strasse/>

<postleitzahl/>
<stadt/>
<maximaleDauer/>
<minimaleDauer/>
</MyProcessResponse>
</part>
</outputVariable>
--> This was moreless expected, since I tried to copy the stuff to some wrong place.
Command 3:
<copy>
<from variable="CaptureData_1_globalVariable"
part="payload" query="/task:task/task:payload/ns0:MyProcessResponse"/>
<to variable="outputVariable" part="payload"
query="/ns1:MyProcessResponse"/>
</copy>
Result 3:
--> Task does't return (!!!). In the BPEL Worklist, the task is completed, however in the BPEL console it still apears as "waiting to return from Human task".
Does anyone have a hint on how to copy the values so that I get exactly the structure that I printed at the very top?
Thanks for help. Rock On !Hello everyone,
It seems that we are talking about different things, I am afraid. Let me describe the scenario once again:
- I want to have a BPEL process with more than one role involved
- This process should be used to gather some complex data.
- All data gathering should be done through HumanTasks.
So I defined an xsd complex type, that contains a sequence of fields. This complex type should be part of the process payload.
Now before HumanTask 1 is called, I copy the contents of this variable into the input for tasks1. This works fine and I see the appropriate values, when opening the Human Task in the BPEL worklist application.
Now after HumanTask1 is completed, the values I entered inside that tasks are returned as a variable from the HumanTask. My problem is, that I cannot copy the contents of the task back into the main process. With simpleTypes this is relatively ok, since Jdev supports the assembling of the copy operation, however for complex tasks it fails.
A typical scenario for this would be where e.g. a customer fills a shipping address and afterwards a store staff fills product details in the same order. In Java this could be solved via "pass by reference". Who can provide an example? -
How to take human task values and store them in DB table
Hi, I have a workflow and when I assign the task to someone I want to store some info in a database table that I created.
I have checked the box allow task and routing customization in bpel call backs.
And under the on Assign message, I put an assign bpel construct and an invoke.
in the assign construct I am trying to copy some of the elements from my humantasks_globalvariables to certain columns in my database table.
I have found out you can't copy them directly because the humantasks_globalvariables are of type string and my database columns are anonymous. So I tried using parseEscapedXML(), when I do this I get the error that
oracle.fabric.common.xml.xpath.XPathFunctionException: parseXML() expects the argument to be either a string or an XML element.
The humantasks_globalvariable I am using says it's of type string but it gives me this error.
I am obviously doing something wrong. If anybody know how to take values from a human task and store them in a database table any help would be greatly appreciated.In the actual database the column types are varchar2. But when I drag an invoke from the bpel constructs I associate it with by DBadapter partner link and click the button automatically create input variables. It creates an xsd and this is what one of the elements looks like.
<xs:element name="anyvalue">
<xs:simpleType>
<xs:restriction base="xs:string">
<xs:maxLength value="20"/>

Tom....For deploying a bpel with human task, you need a bpel engine. oc4j_soa instance has the BPEL engine. Thats why.

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. The idea is to display the task details in BPM worklist.
[04:10:53 PM] [Deployer:149034]An exception occurred for task [Deployer:149026]deploy application RevisionApprovalMgmtTaskFlow [Version=V2.0] on soa_server1.: null.

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,
ManojWhat 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

Error while deleting instances and Human Tasks arent deleted
Hi,
The Error:
Cannot delete instances.
The process domain was unable to purge the instances from the datastore. The exception reported is: [POL-5130] table or view SYSTEM.WI_FAULT not found
Please check that the machine hosting the datasource is physically connected to the network. Otherwise, check that the datasource connection parameters (user/password) is currently valid.
sql statement: DELETE FROM wi_fault WHERE domain_ref = ?
When I query tasks over a jsp i also get the uncompleted human tasks from the deleted instances ( the try to delete them, i think they are there, but in the BPEL Console i cant see them anymore).
The Error occured since i patched my oracle soa suite 10.1.3.1 to 10.1.3.3.
What can I do?
I hope someone can help me.
My best RegardsI think you didn't ran the upgrade-script when you've installed the patchset 10.1.3.3 to your bpel environment.
Check the readme file of the patchset and you will see in the post-installation tasks you need to run the upgrade-script to patch your database environment as well.
Kind regards,

Edited by: user9351838 on 15-Feb-2012 18:45Seems you Human Task has run into not finding the input configurations you have made for the same.
Please check the .task files generated. and delete it from Composite and trying recreating the Human Task.
