Accessing output variables from human task

Hi,
I added a human task in my process (jdev 10.1.3) and set up a parameter to be an input field in the jsp. However, I could not find a way to copy the value from this particular variable even though this parameter is a child of payload. Do I have to define the query manually or did I miss something?
Thank you for advice,
Mirco

Ok, I crosschecked the examples and it seems, that there is indeed an example for what I am looking for. In the LoanPlusDemo there is a StarLoan process and that contains the following assignment following a human task:
<sequence id="BpSeq3" >
<assign id="BpAss4" >
<copy>
<from variable="LoanApproval_globalVariable" part="payload" query="/task:task/task:payload/auto:loan"/>
<to variable="loan" query="/auto:loan"/>
</copy>
</assign>
</sequence>
Now considering the input structure:
<task>
<title>Loan application for</title>
<payload>
     <loan>
     <loanApplication>
<ns1:SSN>123222</ns1:SSN>
<ns1:email>[email protected]</ns1:email>
<ns1:customerName/>
<ns1:loanAmount/>
<ns1:carModel/>
<ns1:carYear/>
<ns1:creditRating/>
</loanApplication>
−
     <loanOffer>
<providerName>Star Loan</providerName>
<selected>false</selected>
<approved>false</approved>
<APR>47</APR>
</loanOffer>
</loan>
</payload>
How do you know how exactly to create the copy rules? JDev does not support this, that much was answered before. I would absolutely appreciate if someone could
1. Tell me something about the namespaces in the copy rules e.g. why is it /auto:loan and not just /loan?
2. An example on how to create such things.
One of the two might be sufficient.
Thank you.

Problem in setting dynamic expiration duration from Human Task

Hi,
I have a BPEL process, in which the Human task expiration has to be set dynamically..
In the , I have set the expiration duration with this :-
<copy>
<from expression="xp20:format-dateTime(xp20:current-dateTime(),'PT1M')"/>
<to variable="initiateTaskInput" part="payload"
query="/taskservice:initiateTask/task:task/task:systemAttributes/task:expirationDuration"/>
</copy>
Do not get confused with 'PT1M' .. I want the duration to be 1 minute... Had I used 'PT1M' as a String and assign to the expirationDuration var, it would have caused an error... It needs to be fromatted as a Date..That's y i took this approach ... I am sure this is working fine as I have checked the payload of the task..
It has a proper duration..
<initiateTaskInput><part xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" name="payload"><initiateTask xmlns="http://xmlns.oracle.com/bpel/workflow/taskService">
<task xmlns="http://xmlns.oracle.com/bpel/workflow/task">
<systemAttributes>
<expirationDuration>PT1M</expirationDuration>
Now in the Human task definition(.task file), I have set the expiration duration with "By Expression" option in this way..
<globalConfiguration>
<owner>oc4jadmin</owner>
<expirationDuration duration="/task:task/task:systemAttributes/task:expirationDuration"
type="XPATH"/>
</globalConfiguration>
The problem is the task(at runtime) cannot evaluate the expirationDuration from the XPATH..
I checked with the WF_TASK table in the orabpel schema ...
When I use a static duration EXPIRATIONDURATION cloumn gets assigned properly (ie PT1M).. But when i take the XPATH approach, it translates to PT0S.
Can someone look into this please ?
Struggling with this for quite sometime...

If the Human Task shows status complete, then it's possible that there was an error in the output data association in the process. In EM do you see a fault on the output for the Human Task activity, or if PS4FP the process will go to suspended state if the data association fails.

Cannot use jstl tag for jsp page which generated from Human Task

Hi
Plz help me.
I have tried to using jstl in jsp which generate from Human Task and I deploy it to server( by ant on Jdev ) to see task detail in Oracle Worklist application. But when i submit task and then I access to worklist to see task detail, the error has show in page that "OracleJSP: An error occurred. Consult your application/system administrator for support. Programmers should consider setting the init-param debug_mode to "true" to see the complete exception message. " .

How to edit task form generated from human task (.jspx)???

I created simple SOA application with simple Human task (from this tutorial http://redstack.wordpress.com/2010/01/08/human-workflow-in-11g/ but it doesnt matter) in JDeveloper. Then I generated standard form from human task (Human task -> Auto-Generate Task Form).
The question is, how to make own form? Not the generated default, but with my own logic...That form is jspx, not jsp, and thats the main problem, in this JDeveloper everything is a bit complicated.
I tried delete whole generated content, and just import my created file.jsp into jspx like below, but without result. How to import jsp into jspx? I dont want to completely rewrite my existing jsp into jspx and copy it over default...

Accessing public variables from other classes

Probably a simple questions, but how can I access a variable from another class. My exact situation is as follows.
A class called WorldCalender has a variable which is defined: public int hour; (the value is given to it elsewhere).
I want to access this variable and increase it by one in a subroutine in the class Hour. In this class I have put: WorldCalender.hour++; but it doesn't seem to work. How should I do it?

don't expose the hour variable at all.
have a method eg addToHourBy( int hrs )

BPEL Test waits forever to receive callback from human task service

Hi,
I've created a test (CreditCardInvalidTest.xml) to test a bpel process (testbpel.bpel) which contains a call to a human task service. The problem is when the test executes it waits forever to receive the response message from the human task service but clearly i've emulated it! Would appreciate help.
I've attached both files and highlighted the relevant sections. Thanks.

RaviKiran,
I agree that the explanation oracle provided in the attach link, is a bit confusing. The main goal there is to describe the behavior of processes, when there is a need to combine, or split the transactions within those processes (or in some cases the processes themselves).
The thing is - The default transaction for a synchronous process is requiresNew. That was until version 11.1.1.6. On this last version, you are asking to enter a Transaction parameter when creating a new synchronous bpel process. The default value being prompt is required and that's what causing the problem – You automatically accept the default.
The assumption is, that developing bpel processes, should come with understanding of all those behaviors.
The problem for my understanding is that some of those behaviors were not so cleared until now.

Call web service from human task

Hi All,
I have a requirement to call webservice inside human task flow. I have three participant in my human task flow. Let suppose A, B and C. When A approves then task will be assigned to B and when B approves it will go for C.
My requirement is that, when A approves , then i need to call one external webservice to update database. I did not get any option to call webservice inside human task flow.
Please help.
Regards,
Sunil

Thanks userN for your wonderful reply but i have one more question.
As per your instructions i have enabled call back events in Human task flow. In this way i got while loop inside my BPEL. In onTaskAssigned operation i am now trying to call external web service. My requriment is to call external service and get data from service. After getting response from the webservice, i want to assign it to next participant.
But in this case, when user B approves, it goes to onTaskAssigned block and i am able to make external web service also but mean time, it has been assigned to User C which i do not want.
I want Human task flow to wait for the webservice response then only assign it to next participant.
Please help, is there any option to do it.
Regards,
Sunil

How to access a variable from within a symbol.

How do I access a variable set outside a symbol from within that symbol?
Thanks

If you set a variable on stage ,say
sym.setVariable("stageVariable", "I am stage variable");
You can access it from within a symbol using :
var myVariable = sym.getComposition().getStage().getVariable("stageVariable");
Basically you need to get handle to the symbol in which the variable is defined.

How to map payload from Human Task to BPEL

Hi,
I have created a human task form for which I send two parameters from the BPEL process.
The user is able to update the fields containing the sent parameters and then click 'APPROVE' or 'REJECT'. However, I need the values of the updated fields to be returned and not the 'APPROVE' or 'REJECT strings.
Can anybody help me with this?
Alex

Hi Alex,
If you checked the Editable via worklistapp box then you dont need to update the values.
These values automatically update the values of these parameters in human task if you properly mapped the values.

Priyanka

Is there any way at all of accessing captivate variables from flash?

Hi,
I would be grateful for any help on this one. I have been working in flash and I wanted to know whether there is any way at all of calling/accessing captivate 4 variables from flash (I'm working in flash Cs4 Actionscript 3.0 and I'm trialling Captivate 4, but I just want to know whether there is any way/method of communicating between a flash file and a captivate 4 file, and if so, can this be done with an embedded captivate 4 file/swf). Surely there must be a way of communicating between the two - they are both Adobe products!
Thanks for any help, pointers, advice, tips in advance.

Hi Louon,
Don't know if this would help you.

We have many experts here who could give more precise answers.

Access payroll variables from custom payroll function

Hi All,
I have a requirement to create a custom payroll function that returns some data from IT0006 and IT0032.
I have written the code in PCBURZDE0, as the payroll is for Germany, it does read the data needed.
My question is, how I can access the variables specified for the function in the payroll schema.
Schema definition in PE01
Zeile     Fkt        Par1 Par2 Par3 Par4 D Text
000010 BLOCK BEG                              Fahrradleasing
000020 _DFRD &PRO GEN
000030 BLOCK END
If I double-click Par1 for function _DFRD (&PRO), then I see he two variables I should write the data to:
Zeile VarArg. FZ T Operation        Operation Operation Operation Operation Operation *
       -------------+---------+------------------+---------+---------+---------+---------+
000010                  AMT= PKWWRPRINT     *
000020           1     AMT= ENTKM PRINT
So, as I understand I should write the two variables PKWWR and ENTKM, I have the values in the function code, but I don't know how to access these variables.
Thanks for your help!

2 - You mentioned that you had created a Custom Function to read IT0006 and IT0032, and I only suggested to you that you could have that Custom Function generate Information WageTypes and save them in the Input Table where they could then be used in PCRs.
3 - I did not mention that you can read only one value through operation AMT, but I mentioned that using AMT=xxxxxx followed by AMT=yyyyyy means that the first statement is useless. On the other hand, using AMT=xxxxxx followed by AMT+yyyyyy and AMT+zzzzzz will result in the amount being the total of the 3 values.
4 - Please read some documents on Schemas, Functions and PCRs, such as in the Wikis on this site, and study your current Payroll Schema, it's sub-schemas, it's functions and the operations in it's PCRs. Note that t-code pe01, pe02 and pe04 can be used to find some documentation on functions and operations.

Accessing another variable from another application

I was wonder how I can access another variable form another application?
For example: I want to access :P4_EMPLOYEE_NAME from app ID 104 when I am doing is from an activity in page 2 on app ID 142.
I had a search before, but I am looking for an unambiguous response.

Greg - About all you can do is call the function htmldb_util.fetch_app_item(p_item => 'F104_ITEM', p_app => '104'). The application you call this function in must be sharing a session with the application from which you are fetching the item, both applications must belong to the same workspace, and the item you name in the argument must be defined as an application-level item in the fetched-from application.

Remove Actionable links from human task notification??

Is posible to remove the link from the human task notification mail.
Thanks...

yes, if you recompile the *.jar and remove the setting "make notifications actionable" (you can find it in the human task definition)

OUTPUT variable from dynamic query with openquery

I am working on a dynamic sql statement that uses openquery to retrieve some columns from an Oracle source. My goal is to take the variables from the select openquery statement and store them, so they can be passed to an insert statement. I am
having no problem getting the emplid but the first_name and last_name are NULL
Any help would be appreciated.
DECLARE @sql nvarchar(max)
declare @emplid varchar(11)
declare @first_name varchar(50)
set @emplid = '1234'
BEGIN
SET NOCOUNT ON;
SET @sql = 'select distinct emplid,
First_name ,
Last_name
from openquery(DWHCRPT, ''select p.emplid, p.First_nAME, p.last_nAME
FROM PS_OCC_BIODEMO_S P
where P.emplid = ''''' + @emplid + ''''''') A';
EXEC SP_executesql @SQL, N'@emplid VARCHAR (11), @first_name varchar(50) OUTPUT', @emplid, @first_name = first_name;
select @emplid, @first_name --currently returning NULL
END

Patrick's query would work, but it would drag the entire table over to SQL Server, which could be expensive.
The code you posted have several flaws. You are not assigning @first_name, and you have failed to provide OUTPUT for the actual parameter. Also, the DISTINCT looks out of place. Isn't emplid a key?
This should work better:
SET @sql = 'select @first_name = First_name
from openquery(DWHCRPT, ''select p.First_nAME, p.last_nAME
FROM PS_OCC_BIODEMO_S P
where P.emplid = ''''' + @emplid + ''''''') A';
EXEC SP_executesql @SQL, N'@emplid VARCHAR (11), @first_name varchar(50) OUTPUT', @emplid, @first_name = @first_name OUTPUT;
select @emplid, @first_name --currently returning NULL
Also, look at this link for some tips how to write queries with OPENQUERY without going insane over all nested quotes:
