Return ParamaterMap from taskflow.

I am calling a bounded taskflow(A) as a popup inside another bounded taskflow(B). The called taskflow(A) returns multiple values.
I am not able to retrieve the returned values of the called taskflow(A) in the calling taskflow(B).
Is there any way I can return all the values together in ParameterMap.

Thank Timo.
But in my use case, taskflow(A) is not used as a region. It is called inside taskflow(B) as taskflow activity. Here I can return single value. But in my case I have 5 values that need to be returned to taskflow(B).

Return value of taskflow as region in fragment.

Hello All,
I would like to ask a question about region, task-flow and its return value.
I have one task-flow which I want to use it everywhere in my application. It shows a list according to its parameters, make users to check some of the values and return the checked values as a list. It has 4 input parameters and one return value (which is the checked items that caller want). There is no problem when I use it inside taskflow with task-flow-call activity. But when try to use it inside fragment (popup) as a region(or dynamic region) I can't get the return value of my task-flow. It's because I can't find a "return value option" in a region.
How can I get the return value of this task-flow when I use it inside fragment (or popup)?
I've searched from this forum, googled it and found nothing.

Hi,
there are many solutions to this but one, the one you expect doesn't work. You could define a managed bean in the calling task flow (put it into view scope) and pass it as an input parameter to the task flow. In the task flow you then change the managed bean before you exit the task flow. Then in the calling task flow, you access the managed bean to read the return value from it. This is how the Dynamic Tab Shell template does it with the tab context. This should work for you as well

Calling task flows return activity from Jspx page.

Hi ,
Using JDev11.1.1.6
I have created template for home page, drag and dropped the task flow(Main Task flow) as region.
Main task flow contains other 2 taskflows with control flows and other 2 taskflows contains Task flow return activity to navigate back to Main task flow.
I need to call task flow return activity from jspx page.
How it can be acheived? can you please suggest me.
Thanks and Regards,

What i have done:
Having page template which has logout and home page links. Use this template to create homePage.jspx, Next drag the main task flow to create a region inside the homePage.jspx.

How to close PopUp (from taskflow region)???

Can someone, please, explain how to solve this use-case:
I have PopUp in which I put a region (in which is a small TaskFlow consiting of 2 JSFFs). I want to have Cancel and OK buttons in both JSFFs in TaskFlow. How to close PopUp from within TaskFlow ??? I saw the TaskFlow Return component in ADF TaskFlow diagram components (in palette) but haven't found any help/documentation on it. Or, should I use Return listener on command button used to rise popup (but, still, how to close popup from taskflow?)?
Any help would be great!
Thanks in advance,
Marko

mimarko,
Regions/Taskflows are meant to be isolated reusable components. They are not meant to
have knowledge of their parent or container. That said, code contained with in a region should not attempt to reach out an modify the parent. Regions can fire contextual events that can be handled by a listener declared in the parent pages pageDef. However, attempting to close a popup from a context listener would be bad practice. The easiest fixt is to put the popup in the taskflow for your region. That will create a reusable popup that you can use through out your application.

How to get return values from task flow in af:region ?

Hi!
I'm working with a taskFlow that is rendered inside a popup using the "popup inside a region pattern" (http://www.oracle.com/technology/products/adf/patterns/popupregionpattern.pdf), but now this taskFlow has an input parameter and a return value definition. So the question is how to get a value returned by this taskFlow thas is called inside a region?
Any suggestion?
Thanks in advance!

Hi,
write the value to a shared memory scope like session and read it in the regionNavigation listener. If you follow the paper you refer to then the listener determines of the viewId is null, this a return happens. It wuld then look in the memory scope for the return value.
Another option would be to use an object that you pass as an argument to the task flow you open in the popup. Then you change the object you passed in, which then makes the return information available in teh calling flow. The object you pass in would have to be in a shared scope too

How to get return value from java and read by other application?

i want to read return value from java and the other application read it.
for example:
public class test_return {
    test_return(){
    public int check(){
        return 1;
    public static void main(String args[]){
       new test_return().check();
}from that class i make as jar file. How to read the return value (1) by other application?
thx..

If your installer is requiring some process it invokes to return a particular value on failure, then the installer is seriously broken. There are a bazillion commands your installer could invoke, and any of them could fail, which in turn could invalidate the entire install process, and any of them could return any value on failure. The only value that's consistent (in my experience) is that zero means success and non-zero means failure, with specific non-zero values being different in different programs.
About the only control you have over the JVM's exit code is that if your main method completes without throwing an exception, the JVM will have an exit code of 0, and if main throws an exception (either explicitly or by not catching one thrown from below), it will be non-zero. I'm not even sure if that's guaranteed, but I would guess that's the case.
EDIT: I'm kind of full of crap here. If you're writing the Java code, you can call System.exit(whatever). But nonetheless, if your installer requires certain exit codes from any app--java or otherwise--you have a problem.

Have your tried pr.exitValue() ?
I think you also need a finally block that destroys the subprocess

Hi,
What kind of web page do you have? Do you have possibility to for example make RFCs? Then you could trigger events (with parameters that could "return" the values) and the workflow could react to those events. For example your task can have terminating events.

Remote Object - not able to get the returned value from java method

     Hi ,
I am developing one sample flex aplication that connects to the java code and displays the returned value from the
java method in flex client. Here I am able to invoke the java method but not able to collect the returned value.
lastResult is giving null . I am able to see the sysout messages in server console.
I am using flex 3.2 and blazeds server and java 1.5
Here is the code what I have written.
<?xml version="1.0" encoding="utf-8"?><mx:WindowedApplication xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute" backgroundColor="#FFFFFF" initialize="initApp()">

     public String setName(){          System.
out.println("Name changed in Java");
          return "Name changed in Java";
And I have configured destination in remote-config.xml
<destination id="sro">
   <properties>
    <source>SimpleRemoteObject</source>
    <scope>application</scope>
   </properties>
</destination>
Please help me .

You are not able to get the returned value because if you see the Remote object help you will realise you have to use result="resultfn()" and fault = "faultfn()"
In this you define what you wish to do.
More importantly in the remote object you need to define which method you wish to call using the method class like this
<mx:RemoteObject id="remoteObj" destination="sro" result="r1" fault="f1" >
     <Method name="javaMethodName" result="r2" fault="f2"/>
<mx:RemoteObject>
r2 is the function where you get the result back from java and can use it to send the alert.

Help with returning query from loadURL()

I finally came across loadURL() and figured out that I can
use it to invoke my ColdFusion components without page
reloading--very handy!
Now, I need to figure out how to do this to return values
from my components. Has anyone done this and have an example I
could see, or at least point out to me a suggestion of code for
successfully doing this?
Right now, my component looks like this:
<cfcomponent output="no">
<cffunction name="getComments" access="remote"
output="no" returntype="query">
<cfset var rsComments = "">
<cfquery name="rsComments" datasource="xmlTest">
SELECT *
FROM comments
ORDER BY commenter DESC
</cfquery>
<cfreturn rsComments>
</cffunction>
</cfcomponent>
I am trying to use loadURL() as follows:
function myQuery() {
var myDatasetURL = 'xmlTest.cfc?method=getComments';
var req = Spry.Utils.loadURL("GET", myDatasetURL, true);
In Firebug, the "Response" shows a serialized WDDX packet.
I've not really messed with these before, so any help would be
greatly appreciated!
Thanks
Joel

Your first mistake was to choose an array. An array has a fixed length, so it's not appropriate for storing a sequence whose length you don't know in advance. You should choose a List instead; an ArrayList would be a reasonable implementation to choose.
Then you just add the Point to the ArrayList. Here's how you declare it:
List<Point> points = new ArrayList<Point>();and here's how you use it in the listener:
points.add(evt.getPoint());Returning anything from the listener to its caller, which is something buried in the GUI hierarchy, would be... um... pointless.

You need to have either OUTPUT parameters or use RETURN statement to return a value in stored procedures. RETURN can only return integer values whereas OUTPUT parameters can be of any type
First modify your procedure to define return value or OUTPUT parameter based on requirement
for details see
http://www.sqlteam.com/article/stored-procedures-returning-data
Once that is done in SSIS call sp from Execute SQL Task and in parameter mapping tabe shown above add required parameters and map them to variables created in SSIS and select Direction as Output or Return Value based on what option you used in your
procedure.

Return data from all columns apart from a certain data type.

Bit stuck on something, hope somebody here can help:
I want to do a 'select * from ' a table, to return all columns except ones of a certain datatype. ie. I want to return data from all columns, excluding columns of datatype 'SDO_GEOMETRY'.
This gives me the list of columns:
SELECT COLUMN_NAME
FROM   USER_TAB_COLUMNS
WHERE TABLE_NAME = 'ORDER_ITEM'
AND   DATA_TYPE <> 'SDO_GEOMETRY'; But I can't seem to take it any further...
Now if I knew the columns beforehand, then of course I could just list them, excluding the geometry column, but this is to be used for a plug-in for MS Word, where a user can pick database columns to dynamically fill a report from - but I don't want the geometry columns as these can't be handled in this way.

Hi Reggie,
> connects to the database and presents a list of tables
My guess is that this macro is written so it selects from all_tab_cols.
Change that plugin and let it select from a view like the one above. That way, the users won't be able to see/pick anything that you are not able/willing to present for them.
Edit:
You could even tease your users, and let them see the columns, but not being able to pick them.
create or replace view available_tab_columns
as
   select decode(pickable.data_type, null, 0, 1) pickable
         ,atc.* -- narrow down yourself
     from all_tab_cols atc -- or maybe user_tab_cols
         ,(select 'CHAR' data_type from dual union all
           select 'DATE' from dual union all
        select 'NUMBER' from dual
           -- complete positive list, yourself
          ) pickable
    where atc.data_type = pickable.data_type(+);Regards

Report 2 returning data from previously ran report 1 - Plus/Viewer

Hello,
We have an issue running through discoverer viewer and plus.
If you run the first report with a parameter for the year with this returns the correct data. However if you run report after the first with year 09-10, the 08-09 data is returned again from the previous report
It doesn't matter which order you run them i.e. if you run the 09-10 first and then the 08-09 the 09-10 data is returned.
The reports work fine when run in Discoverer Desktop.
When 2nd report is run after first it returns the data that appears in the first. This Does not happen on Disco Desktop. The SQL from the reports also runs correctly in TOAD.
Metalink notes suggest turning of the Webcache but this is not turned on in either apps tiers
I have also recreated both reports and this has not made a difference either.
Regards
Rachael

Hi,
Even with webcache turned off Discoverer holds the results of the last run from plus/viewer in the application server and will return these results unless an explicit refresh is entered. Normally, if different parameters are entered this is recognised and the report is re-run. I don't know how you are running your report but for some reason it is not recognising the new parameters and returning the last result set. A refresh should return the correct results.

Getting Return values from RFC function call with visual basic

Hi,
I am creating a sample app to connect to a SAP system which call its RFC functions created with ABAP. It was known that the function will return more than 1 return values.
   SAP Function name ==> "ZFMTP_RFC_GET_RESULT"
        Export parameters (to SAP):
                - Student Name [char 10]         ==> "STUNAME"
                - Student ID         [char 20]        ==> "STUID"
       Return values (From SAP):
                - Results [char 10]        ==> "RESULT"
                - Remarks [char 200]        ==> "REMARKS"
i have managed to get sample codes for connecting and call a RFC function with vb but they only get a return value. How do i retrieve multiple return values like the above function "RESULT" and "REMARKS"?
Here's my vb code to accessing the function
        Dim R3 As Object
        Dim FBFunc As Object
        Dim returnFunc As Boolean
        Dim connected As Boolean
        R3 = CreateObject("SAP.Functions")
        R3.Connection.Client = "000"
        R3.Connection.User = "BCUSER"
        R3.Connection.Password = "minisap"
        R3.Connection.Language = "DE"
        R3.Connection.System = "dtsystem"
        R3.Connection.Applicationserver = "xxx.xxx.xxx.xxx"
        connected = R3.Connection.Logon(0, True)
        If connected <> True Then
            MsgBox("Unable to connect to SAP")
        End If
        FBFunc = R3.add("ZFMTP_RFC_GET_RESULT")
        FBFunc.exports("STUNAME") = "Jonny"
        FBFunc.exports("STUID") = "12345"
        returnFunc = FBFunc.Call() <<== How do i get the return value? or RESULT and REMARKS of the RFC Function?
thanks alot.

The ways to return data from a stored procedure.

Hi, I know there are three ways to pass out a value from a Microsoft SQL stored procedure, but I have no clear idea what Oracle SP can do, I know Oracle doesn't support multi-recordset(v8), can not return a recordset by a inner select query, but I do know there is a cursor object, which doesn't like its counterpart in Microsoft SQL server, is a choice under most situation. Here I wonder anyone who is good at Oracle can give a list of all ways to return data from a SP, including example is more better, thanks.

Here is a way to get return a record from a function and a procedure. You need to be familiar with Oracle packages as well as stored procedures and functions:
CREATE OR REPLACE PACKAGE EmpPkg AS
cursor cEmp(pEmpno in number) is
select empno, ename, job, hiredate, sal
from emp
where empno = pEmpno;
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype);
END;
CREATE OR REPLACE PACKAGE BODY EmpPkg AS
FUNCTION GetEmployee(pnEmpNo in number) RETURN cEmp%rowtype IS
rEmp cEmp%rowtype;
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into rEmp;
close cEmp;
return rEmp;
END;
PROCEDURE GetEmployee(pnEmpNo in number, prEmp out cEmp%rowtype) IS
BEGIN
open cEmp(pnEmpNo);
fetch cEmp into prEmp;
close cEmp;
END;
END;
Here's how you use the package:
DECLARE
rEmp EmpPkg.cEmp%rowtype;
BEGIN
rEmp := EmpPkg.GetEmployee(7782);
dbms_output.put_line(rEmp.ename);
EmpPkg.GetEmployee(7902, rEmp);
dbms_output.put_line(rEmp.ename);
END;
Note that you can return any Oracle data type from a function. Likewise, you can specify any Oracle data type as an out parameter in a procedure. Also, you can make a parameter both an in and an out datatype like this:
PROCEDURE GetEmployee(pnEmpNo in out number);
I hope this puts you in the right direction.
