Calling ON DEMAND process for outside APEX

Hi All,
I would like to call an ON DEMAND process from outside APEX (using HttpClient java class). I think i have to use wwv_flow.accept but i'm bit lost on how to specify that i'm calling a process on demand.
Has someone already tried this ? samples or advices would be more then welcome ... The goal behind the scene , would be to have an Apex page acting like a servlet (HTTPClient send a xml request and receive an XML response from the apex page).
Thks.
Thierry

Thierry,
You need to set up the HTTP request as you would if invoking your application+process from a URL, e.g.,
..f?p=100:0:9876543210123456789:APPLICATION_PROCESS=<name of process>
..in which request header the authentication cookie is provided, and in which request the correct session ID is provided. You could alternatively do a POST to wwv_flow.show, bypassing the f procedure, but I don't know if that will save you any steps.

Possible to download file using ajax on demand process?

In the past I've used procedures with the wpg_docload.download_file function to download files by granting public to the procedure and executing the download from a report link (such as http://localhost:8080/apex/schema_name.download_blob?file_in=xxx)
I'd like to move to the download to a link that's called from an ajax called on demand process. Is this possible? I have got the report link calling a javascript function passing the rowid in and running the same download_blob procedure via the on demand process but, whilst the code runs OK it does not return the prompt box for the user to open/save the file. I guess this might be because it's not returning it to the javascript in the proper way but I'm v flaky wrt to ajax.
var ajaxRequest = new htmldb_Get( null , &APP_ID. , 'APPLICATION_PROCESS=download_blob' , 0);
var ajaxResult = ajaxRequest.get();
Thanks
Simon

To be honest, it's not a big deal, I wanted to do it this way as we have data stored as BFILES and some of the downloads are so big they take a while to load into a temp_blob and thus I wanted to call it from java script so I could call a loading "div" 1st, so the user does not see the screen hanging. However I've changed the code to load the BFILE into an actual blob 1st (through an ajax process) and then return a link to the screen pointing to an app process which opens the blob.

On Demand process get url query string

Hi,
When I call On Demand process , is there way inside that process get url query sting or whole url did call On Demand process?
I did try below but it returns null
owa_util.get_cgi_env('QUERY_STRING')Regards,
Jari

You'd know this better than me - but I seem to recall there are 2 Oracle sessions involved in normal page processing - one for the request and one for the response. wwv_flow.show seems to correspond to the response session, not the request session (that might have the env variables you're looking for). Could that explain what you're seeing?

Testcase, how to split up an xml message and call a BPEL process.

Another question.
Considering the following XML message.
<?xml version="1.0" encoding="UTF-8"?>
<rows>
<row>
<id>10</id>
<naam>A</naam>
</row>
<row>
<id>20</id>
<naam>B</naam>
</row>
</rows>
An input message can consist of 1 to about 20000 <row></row> elements. I would like to split up this message into individual <row></row> and call a BPEL process for further processing.
I've tried to use the file adapters feature "Files contain Multiple Messages" Publish Messages in batches of.." This did not work. ( root element expected exceptions ).
I've also tried to invoke an extra async routing service with a mapping which removes the root element. This also doesn't work as it leaves the following ( incorrect ) xml message at the end.
<row>
<id>10</id>
<naam>A</naam>
</row>
<row>
<id>20</id>
<naam>B</naam>
</row>
Which is logical considering how an XSL transformation works.
Is there any way to achieve this?
Any help is appreciated!

You shoul create a while loop, that loops through XML payload for each row. Than you can process each individual row. See also example:

How can I call a Page Process from the Select statement for Report Page

I'm able to call a javascript using the below:
img src="#IMAGE_PREFIX#add2.gif" border="0" alt="Icon 4" onClick="javascript:add_connect1('||CPORT.ID||')"
But Now,
I'd like to accomplish (2) New things:
1. instead of using,....... onClick="javascript:add_connect1,
I'd like to call a Page Process, onClick=
2. I'd like to be able to call two different processes onClick.
a. onClick="javascript:passBack('||ID||')"
b. onClick= <Please see my question #1 above>
Can someone please help me with the syntax for this,
If indeed it can even be done?
Thanks- Gary

Greg.
It seems that my situation is the one you describe in you second paragraph, where you mention:
you could then add the ID column value as a parameter to the javascript functionBut,
I do not know how to reference the variable in my javascript nor how to use it in my on-demand process.
If you can hellp me past this last little bump, then I think I will be able to use these skills in Sooo many different areas of my design.
Here's what I've got so far:
A. In the select statement I identify the javascript as:
onClick="javascript:connect_port('<font color=blue>''||ID||''</font>')";
B. In my javascript I have this:
<script language="JavaScript" type="text/javascript">
function connect_port(ID)
var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=CONNECT_PORT',0);
gReturn = get.get();
get = null;
</script>
C. In my on demand function I have this:
BEGIN
INSERT INTO CCONNECTIONS_B
BLDG_ID,CLST_ID,PORT_ID,STRAND_ID
) VALUES
:P2004_BLDG_ID,:P2004_CLST_ID,:P2004_PORT_ID,:P2004_STRAND_ID1
END;
You can see that I dont know how to use the value for 'ID' in either the javascript or the On-Process function.
If you can help me out with this one, Then I can imitate it for the rest.
-Gary

Calling an On Demand Process in PL/SQL Region without using AJAX

Hi!
I am trying to find a way to call an On demand Process in a PL/SQL Reports Region. The reason is that i need Reportings for about 20 Pages that look like the same but have different parameters. I already have some Processes that return SQL Statements and it works fine. But these Reportings are more complex and it's not possible to return it wirh a SQL Statement.
I have seen some solutions in this forum that used AJAX to call such a process. The problem is, that I'm not allowed to use AJAX because activeX is diabled. I tried it and it works but i need another way to solve this process call.
Thanks in advance
Philipp

At the moment I cannot say if your link can help. Right now the call of the On demand Process looks like this:
Inside annonymous PL/SQL Region:
<script type="text/javascript">
get = new htmldb_Get(null,'||:APP_ID||'.,'APPLICATION_PROCESS=F_REPORT_NAME',0);
gReturn = get.get();
document.write(gReturn);
</script>

Outside Processing for Multiple Work Orders

I have a request for the following process in 11.5.10.2:
I have product lines "A", "B", "C" and "D", each with variable demand. Each of these get sent for outside services on a periodic basis.
Using the OSP functionality in Discrete Manufacturing, we want to do one PO to satisfy the supplier.
PO#1 may look like:
- Product A: 500 units
- Product B: 700 units
- Product C: 20 units
- Product D: 1000 units
PO#2 may look like:
- Product A: 0 units
- Product B: 100 units
- Product C: 50 units
- Product D: 0 units
Regardless of the product mix or the number of units being processed, the supplier is going to charge me a flat rate of $1000. I want to burden each of my work orders with its percent contribution to the total PO charge.
Said another way:
($ Flat Rate Charge of PO) / (Total Units of the PO) * (Units on a specific line)
For PO#1:
PO#1 may look like:
- Product A: 500 units = $250
- Product B: 700 units = $350
- Product C: 200 units = $100
- Product D: 1000 units = $500
- PO total = $1200
PO#2 may look like:
- Product A: 0 units = $0
- Product B: 100 units = $1000
- Product C: 20 units = $200
- Product D: 0 units = $0
- PO total = $1200
Each product would have a standard OSP lot charge in the router and variances would be driven by the actual PO.
Is there a way to configure this?

Hi RajaSekhar,
You can definitely get the orders & notifications for two shifts. You can do this by adding all different workcenters in the customization in the backend system.
To do this in the backend system go to Order Processing- and pick the corresponding OrderProcessing Scenario and double click on that- then go to varaint and click on selection report and in that you can add mutiple work centers as many as you need and then save the varaint.
Similarly change the variant for notification processing profile also.
After making changes in the backend, do a replication of syncbo' MAM25_090 and MAM25_095 and then do a sync from the client to get the proper data.
If you have any further doubts please reply back.
Regards,
Siva.

On-Demand Process Running only for authenticated user

I have noticed that an on-demand process is running only for authenticated users - for example a download of a document. For public users it doesn't. I remember seeing a similar question related to ajax on demand in this forum but couldn't locate the thread. Does anyone knows why the process is not running for not authenticated user? The result of a download for a public user is a blank page where the authenticated user gets the file by clicking on the same link.

Creating process for multiple Date fields for update or insert in APEX

hello there,
could someone please help me?
i have a form on Apex based on view that is based on three tables and updating and inserting ok using trigger instead of.
i have a problem now as in my form i have around 75 fileds (items) incuding 30 or more date fields which could be populated or left blank or update later.
so for each date field i have two boxs; one for date, input as dd/mm/yyyy (text field) and second for time, input as 23:45. All dates will be insert or update manually by user. so as i mentioned not all date fields could be poulated at one stage.
so i have created some process and validations and all of them work fine but i came accross if date left blank then (:) giving me problem so i have done following further process for each date field. In real table all the date fields have data type date.
declare
v_my_var date; -- for first date field
str_dy VARCHAR2(10);
dt_indx date;
str_tm VARCHAR2(20);
tm_indx date;
begin
str_dy := :p4_first_date
str_tm := str_dy||' '||substr(:p8_first_date_hh,1,2)||':'||substr(:p8_first_date_HH,4,2);
dt_indx := to_date(str_tm,'DD/MM/YYYY HH24:MI');
IF str_dy is not null then
v_my_var :=dt_indx;
ELSE
v_my_var := NULL;
END IF;
update table 1 set my_date = v_my_var where d_id= :p4_d_id;
end;
above code work fine but one date field of course therefore i have to do same code for each date field with changes and initialise variable again and again for each field.
so i like to ask is there any easy way that is more professional. i was thinking about the procedure and using collection or similar but honestly not much experience on that so could some one please help me?
I will be very thankful.
KRgds

Hi,
You can do the needful by re-using the code if you can give the item names as P8_DATE1, P8_DATE_hh1, P8_DATE2, P8_DATEhh2 etc..So your item name just differs by a sequence.
Now you write function which will return desired date value taking above items as input. Pass item names to this function, get session state using APEX_UTIL.GET_SESSION_STATE('item_name') API.
Now modify you code as
FOR i IN 1..30
LOOP
v_date_array[i] = f_get_date('P8_DATE'||i, 'P8_DATEhh'||i);
END LOOP;
....Now you have all date valus in array. Just write one update as follows
UPDATE TABLE1
SET date1 = my_date_array[1], date2 = my_date_array[2]..
WHERE ....Hope it helps :)
Cheers,
Hari

On demand process time limit.

Hello, I would like to know if Apex has time out limit on "On demand process" ? I have a long running insert query in my on demand process and I was hoping that the process will complete when the query finishes, but it doesn't seem that way. Is the time out for an on demand process the same as the time out time for Apex pages?
George

I was hoping that the process will complete when the query finishesWhy should the Ondemand process run after the PLSQL block has completed.
Do you have some kind of infinite loop happening over the ajax call ? Even so you might face something like "too much recursion" error in Javascript.

Passing value to another form with on demand process

Hi,
This is my first post and I am an absolute beginner to apex (using 4.1)
I would like to pass a value to another form, but to no avail.
I have an on demand process that is being called when a button is clicked (ISSUE)
This process is being called from P33 and I need the value to go to P33_ST_NUMBER_HOLD
DECLARE
v_rownum NUMBER;
BEGIN
for i in 1..apex_application.g_f01.count
loop
    v_rownum := apex_application.g_f01(i);
    apex_debug_message.log_message('row selected: '||v_rownum);
    apex_debug_message.log_message('value: '||apex_application.g_f03(v_rownum));
    htp.p('$x_Value("P17_ST_NUMBER_HOLD",apex_application.g_f03(v_rownum));');
end loop;
END;What am I doing wrong?

Hansen_____ wrote:
htp.p('$x_Value("P17_ST_NUMBER_HOLD",apex_application.g_f03(v_rownum));');This is PL/SQL and you have to use one of these methods to set the item value, But you are using javascript API's in PL/SQL.
FYI - javascript is a client/browser side and it got nothing to do with PL/SQL
:P17_ST_NUMBER_HOLD := apex_application.g_f03(v_rownum);

Are On-Demand Processes Conditional?

Hi,
Within Apex 4.1.1, when an Application Process is created it states, “Note: Conditions are not used for "on-demand" processes. All conditions for processes that run at the "on-demand" process point must be set by the calling process.” Within Apex 4.2.1 it no longer states this message.
1. Does the note mentioned above apply regardless of whether or not you are calling the process from an apex page process (e.g. create process, choose on-demand option) or from an AJAX callback initiated from Javascript. Will the application process condition be ignored in one or both instances?
2. Does the above note still apply in 4.2.1?
Thanks,
JIM

Found the answer.... Eventually.....
http://apex.oracle.com/pls/apex/f?p=38997:8:0::NO
Going to the above link and looking at the APEX 4.2 Early Adopter Changes
Feature : APEX 4.2 Early Adopter > APEX 4.2 Other Features > Remove the restriction that on-demand processes can't have a condition or authorization
Currently on-demand processes don't include the ability to define authorization or conditions. This has been incorporated to provide the same options for on-demand processes as for other components.
In 4.2 On-demand can now use conditions previously the could not.

Error while using ajax addParam function in on demand process

Hi ,
I am calling an on demand process from a javascript that inserts value from a modal from into a table.
function f_insert_transaction()
var ajaxRequest = new htmldb_Get(null, $v('pFlowId'), 'APPLICATION_PROCESS=insert_manual_transaction',73);
          ajaxRequest.addParam('x01', $v('P73_ARRANGEMENT_ID'));
          ajaxRequest.addParam('x02', $v('P73_TRANSACTION_DIALOGID'));
          ajaxRequest.addParam('x03', $v('P73_CUSTOMER_NAME'));
          ajaxRequest.addParam('x04', $v('P73_CUSTOMER_NUMBER'));
ajaxRequest.addParam('x05', $v('P73_SALES_ORDER'));
ajaxRequest.addParam('x06', $v('P73_SO_LINE'));

ajaxRequest.addParam('x10', $v('P73_ITEM_DESC'));
var ajaxResult = ajaxRequest.get();
alert(ajaxResult);
ajaxRequest = null;
}The insert works fine as long as item names range from x01 - x10.
When I add the below
ajaxRequest.addParam('x11', $v('P73_QUANTITY')); The insert stops working, and the alert displays the following error message :
<!DOCTYPE HTML PUBLIC "-//IETF//DTD HTML 2.0//EN">

Hello:
You could concatenate the page-item values into a single string where the values are separated from each other by a suitable delimiter ( a colon for example) and set, x01, to this concatenated value. You could then decompose this concatenated string in the ODP used in the AJAX call to obtain the individual values.
