How to populate an application item using ONCHANGE.

I am trying to populate an application item, TAB_INSTATE using an onchange command. I cannot figure out how to do it. Does anyone know the syntax, or can you point me in the right direction. I am unfamiliar with javascript and have been relying on previous examples, posts. thanks

Hello Karen,
>> I am trying to populate an application item, TAB_INSTATE using an onchange command.
I believe I answered you in here - Re: once more...4 cascading LOVs, 3rd is hidden 4th no longer works However, for future reference…
You don’t have a direct access to an application item, using JavaScript, because application items don’t render on page. You can, however, using the AJAX framework to do that, using the add() method. The generic code I’m using is the following:
<script type=”text/JavaScript”>
function setSessionValue(pItem, pValue) {
var get = new htmldb_Get(null,html_GetElement('pFlowId').value,null,0);
get.add(pItem, pValue);
get.get();
get = null;
</script>This code can set any page or application item value.

Arie.

How to set an Application Item from PL/SQL

I am attempting to set an Application Item
After login to my app, I want to retrieve a row from my SETTINGS table and populate some Application Items with the settings information so that I can
display some of that settings information on every page.
Just to start, I created one Application Item named F106_YEAR
I then created a Shared Components Application Process which executes on New Session: After Authentication
I created this process as an Anynomous PL/SQL block.
declare
aucyr varchar(4);
begin
select year into auctyr
from settings;
:F106_YEAR := aucyr;
end;
I've tried a couple of other Syntax tricks attempting to reference the Application Item F106_YEAR from within PL/SQL (like V('F106_YEAR') but nothing seems to be working.
I'm sure that I am missing something simple. Can someone tell me how to set an Application Item from PL/SQL?
Thanks in advance.

I'm still doing something wrong because this is not working for me.
I've tried both of the following versions as an Application Process set to run on New Session after Authentication:
declare
auction_year varchar(4);
begin
select year into auction_year
from PBUUC.SETTINGS where rownum < 2;
:F106_AUCTION_YEAR:=auction_year;
end;
and I also tried:
declare
auction_year varchar(4);
begin
select year into auction_year
from PBUUC.SETTINGS where rownum < 2;
APEX_UTIL.SET_SESSION_STATE (p_name, p_value);
end;
F106_YEAR is a global Item (shared components).
The select statement works just fine in SQL*PLUS so I know that it is correct.
If I run the debugger and log into the application, here is the output. Shouldn't I see my Application Process get called if it is set to run on New Session after Validation?
My Application process is named RETRIEVE_AUCTION_SETTINGS

How to get web application to use Tuscany without conflicting with SAP SDO

Hi,
We are attempting to run a web application on SAP NetWeaver CE 7.1 SP1 which uses Tuscany SDO. As it now stands We must use Tuscany because the web application will not run with the SAP SDO implementation provided by Netweaver. To ensure that Tuscany is loaded with priority, we have packaged the Tuscany JAR files and their dependencies as a heavy resource, as described here:
http://www.sdn.sap.com/irj/sdn/go/portal/prtroot/docs/library/uuid/60642a88-95fe-2b10-d387-a245d48fc257?overridelayout=true
The final check showed that Tuscany was correctly deployed as a heavy resource and included the following JAR files:
common-2.2.3.jar
ecore-2.2.3.jar
ecore-change-2.2.3.jar
ecore-xmi-2.2.3.jar
tuscany-sdo-impl-1.1.1.jar
tuscany-sdo-lib-1.1.1.jar
tuscany-sdo-tools-1.1.1.jar
xsd-2.2.3.jar
We also verified that the web application using Tuscany has a hard reference to the Tuscany heavy resource.
However, when we try to run the web application, the following error is logged: java.lang.LinkageError: Class commonj/sdo/DataGraph violates loader constraints
The issue is definitely due to some kind of classloading conflict with the SAP SDO library, as the application runs normally when SAP SDO is manually removed from the classpath. Doing this on a production system is unfortunately not an option, though.
So the question is: how to get web application to use Tuscany without conflicting with SAP SDO?

I took a look at the "printerReady" example. Looks like I may be able to use the InetPing (...) function to ping through a range of IP addresses looking for a response.
Any ideas on how to find the MAC address associated with the IP addresses that respond?
We may have multiple units responding and the MAC address will allow the operator to determing which unit to connect to.
I'll try the InetPing to see how it works,

How to add new line item using BAPI BAPI_CONTRACT_CHANGE for contract-ME32K

HI Experts,
how to add new line item using BAPI: BAPI_CONTRACT_CHANGE for existing contract.
Requirement:
Already the contract having two line items using ME31K.
Custom program has to add new line items in existing contract.
Thanks,

I got the solution:
We can do like this:
1. Get all details using details, BAPI_CONTRACT_GETDETAIL.
2. After getting results, append new line item. Then use your BAPI.
Check this posting program.. where this bapi is used, use the same coding technique.

How to set the value of application item using pl/sql in application process

Hi guys,
I want a global variable (application item) whose value will be set at the start when a user logs in to the application. The value will be retrieved from database using a sql query. I do not know the exact syntax to set the value of application item in application process. Also i want to know in which type of application process should i use to set the value of application item when a user starts a session. The value of application item varies from user to user.
Please help.
I am using apex 4.2
Regards,
Waqas

You can use the application item as bind-variable with its name. ie. your application item is named G_MY_APPLICATION_ITEM, then you can access/set it using :G_MY_APPLICATION_ITEM.
For example
BEGIN
    -- assign like a variable
    :G_MY_APPLICATION_ITEM := 'LARRY';
    -- use in a SQL statement
    SELECT WHATEVER_COLUMN
      INTO :G_MY_APPLICATION_ITEM
      FROM MY_TABLE
     WHERE USERNAME = :APP_USER
END;

How to populate another page item based on cascading select lists?

Oracle 10gXE
APEX 3.2
I've created cascading select lists based on the examples (using Javascript and AJAX) that i've seen on this forum. Thanks for help on that!
Now that I have these LOV's being populated without needing to submit the page, how do I take the value that is presently in each LOV and concatenate them together to populate another page item? I'm trying to build the URL string that will execute an Oracle Report once the user clicks a button.
Previously, when I had multiple Select Lists with a submit, the URL was being put together using an After Submit Computation that would set the value for an item (P26_REPORT_URL) on the page. Notice that a report parameter (i.e. parameter name and Select List value) is only included if the user has provided a value. The page item that holds these values is then referenced by a button for URL redirect. The URL Target for the button currently is: javascript:popupURL('&P26_REPORT_URL.'), but will not work at the moment because P26_REPORT_URL page item is not changing based on what is selected in the LOVs. Since I'm not submitting anything (do I need to?), how do I put together the values needed?
Computation for P26_REPORT_URL:
DECLARE
l_param VARCHAR2(2000);
BEGIN
l_param := '&REPORTS_URL.&report=&P26_RPT_VIEW..rdf&desformat=&P26_DESFORMAT.&destype=cache';
IF REPLACE(:P26_OLO_CODE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_olo_code=&P26_OLO_CODE.';
END IF;
IF REPLACE(:P26_BEG_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_start_dt=&P26_BEG_DATE.';
END IF;
IF REPLACE(:P26_END_DATE,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_end_dt=&P26_END_DATE.';
END IF;
IF REPLACE(:P26_ORG_CODE_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_org_code=&P26_ORG_CODE_2.';
END IF;
IF REPLACE(:P26_FLAIR_ORG_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_flair_org_code=&P26_FLAIR_ORG_2.';
END IF;
IF REPLACE(:P26_BUDGET_ENTITY_2,'%'||'null%',NULL) IS NOT NULL THEN
l_param := l_param||'&p_agy_code=&P26_BUDGET_ENTITY_2.';
END IF;
RETURN l_param;
END;

Andy,
This is a great suggestion! After I posted, I started looking at a Javascript solution and figured it's probably what I had to do.
However, now the cascading select list no longer working for some reason after I added the function to concatenate the item values. When I remove the showReport() function the select list works again.
Here is what I have in the HTML Header portion of the page:
<script language="JavaScript" type="text/javascript">
function popupURL (url) {
w = open(url,"winLov","resizable=1,width=800,height=600");
if (w.opener == null)
w.opener = self;
w.focus();
function showReport()
var l_param = '&REPORTS_URL.&report=' + $v('P26_RPT_VIEW') + '.rdf&desformat=' + $v('P26_DESFORMAT') + '&destype=cache';
if ($v('P26_OLO_CODE' != '')
   l_param += '&p_olo_code=' + $v('P26_OLO_CODE');
if ($v('P26_ORG_CODE_3' != '')
   l_param += '&p_org_code=' + $v('P26_ORG_CODE_3');
popupURL(l_param);
function get_AJAX_SELECT_XML(pThis,pSelect){
     var l_Return = null;
     var l_Select = $x(pSelect);
     var get = new htmldb_Get(null,$x('pFlowId').value,'APPLICATION_PROCESS=ORG_SELECT_LIST',0);
     get.add('TEMPORARY_ITEM',pThis.value);
     gReturn = get.get('XML');
     if(gReturn && l_Select){
         var l_Count = gReturn.getElementsByTagName("option").length;
         l_Select.length = 0;
         for(var i=0;i<l_Count;i++){
             var l_Opt_Xml = gReturn.getElementsByTagName("option");
appendToSelect(l_Select, l_Opt_Xml.getAttribute('value'), l_Opt_Xml.firstChild.nodeValue)
get = null;
function appendToSelect(pSelect, pValue, pContent) {
var l_Opt = document.createElement("option");
l_Opt.value = pValue;
if(document.all){
pSelect.options.add(l_Opt);
l_Opt.innerText = pContent;
}else{
l_Opt.appendChild(document.createTextNode(pContent));
pSelect.appendChild(l_Opt);
</script>

How to set an application item when report column link is clicked?

I am trying to set the short name of a bread crumb entry when I drill into a detail from an interactive report page.
The master report has a column link with target = detail - "page in this application"
I can pass page items through the URL and they are set on the target page.
How can I set an application item before the target page is called?
Is there a way to set a process before the link is followed?

Kenneth,
I'm not totally sure that I understood the question but, it soounds like you want to set the value of some page items on the page that is opened when you click a link on a column in the master window. Is this right?
If so, you can achieve what you want by creating hidden page item(s) on the target page. In the master page, on which every column provides the link, go into Report Attributes, click on the link column and scroll down to the section labeled "Column Link" Within this section, set the link text to the current column value, e.g. #MASTER_REPORT_COLUMN_NAME_HERE#. Set the target to "Page in this Application" and pick the page number for the target window.
Underneath this you will see a section to set set the value for page items. If you click the flashlight, you can search for the hidden page item that you created above. Use the same value to set it as you did the link text, i.e. #MASTER_REPORT_COLUMN_NAME_HERE#. Do this and let APEX take care of passing the values on the URL.
On the child page, just set whatever control you want to dynamically pick up the value from the hidden field. For example, if you hidden field where named P4_CLEARER_NAME. You could set the title attribute to "Contact Information for &P4_CLEARER_NAME."
You need the preceeding "&" and terminating "." around the name of you hidden page item to do this.

How to configure ADF application to use OAM Identity Assertion ? web.xml

We have a web application developed using ADF (application development framework) and deployed on WebCenter 11.1.1.2 (weblogic 10.3.2)
OID Authentication and OAM identity assertion is configured in WebLogic 10.3.2 .
How to configure security in ADF application (web.xml or weblogic.xml) so that it uses OAM identity assertion (already configured as authentication providers in weblogic server)
Any pointers or documentation so that application (developed using ADF) check for identity tocken and verifies it with one of identity assertion providers.

John,
I have to concur. With OAM you don't need this. OAM intercepts the calls and inserts a cookie for WLS to get user information from.
I strongly advise to go through the above mention OFM Security Guide. Esp. Chapter 10 tells you in every detail how to implement OAM SSO with WLS (with or without OHS as a proxy).
Reading this chapter saves you time and turnarounds on this topic...

Hi again,
Did the popup work ?
For the list item , use the built-in add_list_element in a loop. Example : in the pre-form or when-new-form-instance trigger ,
clear_list('block_name.list_item_name');
for rec in (select column1,column2 from t_table order by 1 desc) loop
ADD_LIST_ELEMENT('block_name.list_item_name', 1, rec.column1, rec.column2);
end loop;
See you
