Business Components pass parameter

I have this BC4J/JSP Application. In a particular JSP form (based on BC4J (account id, account name)), when I click upload file, I want to somehow pass the account id from the business component record on which the user currently has selected, in the URL.
This account id will be passed as parameter. Is there a way to retrieve the current record programatically which the user has currently selected, retrive the accunt id and pass it as parameter.

Edit your SharePoint page and add new text filter web part.
Then pass the text filter value to your performance point report using connections. Your report should include at least one parameter to get the value. More over you can set default value in text filter.

MapViewer: how to manage user selections in business components Java class

Hi list,
I'm a GIS developer with experience on Mapserver and Mapguide. Buit I'm totally new on Oracle Mapviewer and I'm doing a feasibility study on a project where I basically have a very simple GIS use case, but I don't know if it is possible to manage by use Oracle ADF Java API and Oracle Mapviewer.
I would like to use JDeveloper / ADF Business Components / ADF Faces.
This is the use case:
- Mapviewer should display a polygon layer from Oracle Spatial
- Mapviewer should display a polygon layer from WFS
- User should be able to select a polygon on Oracle Spatial layer and another polygon in WFS layer
- ADF Face map control should:
a) hilglight these two polygon
b) execute my buiseness component Java function passing the user selection (id?... coordinates?... or anything useful to get these two polygons in the business Java function) as parameter.
Is it possible?...
Any suggestions (or samples) for point b)?...
Thanks in advance for any help

Hi Arnd,
Thanks for answer.
Can you adreess me to some ADF project that include ADF Geographic Map control?
I've carefully studied what explained in manuls contained in JDeveloper Help. I've made something, but I have some issue I can't solve.
Here you are in details what I've made:
1) I've installed Mapviewer Quick Starter Kit
2) I've configured themes and base map by use on MapBuilder
3) I've built an ADF application with separated business and model-view-controller projects
4) I've created entities and views in ADF business project
5) I've created a JSF page in model-view-controller project
6) I've put inside page an ADF Geographic Map assigning my base map and his related toolbar.
Up to now it worked fine. My problems started at this point, on the attempt to add themes to be exposed to user interaction.
PROBLEM 1
I've seen that there are basically two options to add theme for user interaction:
a) add a predefined themes
b) add a color/point/graph bindable themes
Option b) seems not fit for my needs.
Color theme is only for regions and forces me to set a range of colors (I want to set exatctly two different color for two different table attribute value).
Lines seem not covered from any of them.
So the solution should be option a), predefined themes. But predefined theme seems not selectable and I don't know how to attach a selection listener.
Please note (about selection listener) that in JDeveloper Help, book "Web User Intercace Developer Guide", "Using ADF Geographic Component" there is a code sample, but the explaination on how to enter the backing bean method is truncated (it says "For example," and stop, nothing else).
My questions are: predefined theme can be selectable? And how can I attach the selection listener?.
PROBLEM 2
Up to now I've made no test on WFS themes, but of course, also these themes should be exposed to user interaction in the same way of predefined layers.
Is it possible?...
PROBLEM 3
Legends activated by ADF Map Toolbar seem not working for predefied themes, they display nothing.
Is it possible to fix or workaround in some way?...
PROBLEM 4
Are there any way to print maps?...
Best regards
Francesco

How to create "Business Components Package" in the Jdeveloper ?

Hi,
I installed and set up "Patch 7523554 10G Jdeveloper With OA Extension ARU for R12 RUP6"
I have ran out the test_fwktutorial.jsp and test_fwklabsolutions.jsp.
All links work properly on these pages.
I created HelloWorld page from "Oracle Application Framework Toolbox Tutorials".
Its works properly too.
Then I started to create "Search Page".
I created "Business Component project" in the toolbox.jws.
I was trying to perform step 2.1 "Create the BC4J Package for Client (UI) Objects".
But I didn't find "Business Components Package" in the context menu.
Could you give me advice how can I create package of this kind ?
Thanks.

I created "OA Workspace" and simultaneously with it created "Business Components Package" <yourname>.oracle.apps.ak.employee.
After this it i necessary to creates one more "Business Components Package" <yourname>.oracle.apps.ak.schema.server
I failed to create Package of this kind.
In the "BC4J Tutorial" It seems to me I found similr actions.
I suppose I may perform next step:
Figure 6-3 http://download.oracle.com/docs/html/A97671_01/wtgbc4j.htm#BABIAIEI
Figure 6-4 http://download.oracle.com/docs/html/A97671_01/wtgbc4j.htm#BABJIIII
But I failed to pass these steps.
Could you tell me, please, how to do this?
Thanks.

Help required building ADF-Swing/ADF-Faces using ADF Business Components

My question is in regards to how you can go about building a light swing application to an ADF model?
In particular if I were to say that we were developing a 3-tier project whereby we had a database tier, a series of EJB-ADF façade session beans to the database (middle-tier), and a swing client communicating with the session beans (view-controller tier), how would you go about developing these screens?
In particular can we develop these screens using ADF-Faces and also ADF-Swing?
The EJB session façade beans of course are ADF app modules with customised methods. The methods would return back customised DTO objects. These DTO objects are wrappers to row objects ADF would create. This would be mainly due to making these facade beans web service enabled (Oracle state that these methods cannot return oracle.jbo objects if they are to be web service enabled).
This would be typically deployed to an app server, like Oracle App Server 10G.
Could you please have a look at this, as I am doing a lot of research into this.
eg. Taking example from oracle magazine sept/oct 2006
with slight enhancements
package oramag.frameworks.example.common;
import oracle.jbo.ApplicationModule;
import oramag.frameworks.customdto.EmployeeDTO;
public interface HRService extends ApplicationModule {
void deleteCurrentEmpAndCommit();
EmployeeDTO findEmployee(int employeeId); // new method
import oramag.frameworks.customdto.EmployeeDTO;
public class HRServiceImpl extends ApplicationModuleImpl {
public void deleteCurrentEmpAndCommit() {
Row empRow = getEmpView().getCurrentRow();
if (empRow != null) {
empRow.remove();
getDBTransaction().commit();
public EmployeeDTO findEmployee(int employeeId)() {
EmployeeDTO employeeDTO = null;
EmployeesImpl employees = getEmployees();
employees.setNamedWhereClauseParam("EmployeeId", employeeId);
employees.executeQuery();
if(employees.hasNext()) {
EmployeesRowImpl employee = (EmployeesRowImpl)employees.next();
employeeDTO = new EmployeeDTO(employee);
return employeeDTO;
public EmployeesImpl getEmployees() {
return (EmployeesImpl)findViewObject("Employees");
Now given the above code snippet, how could you turn this into an ADF-Swing/ADF Faces application so that if a user using the swing application enters an employee id, then the application will execute the query on the app server, the app server in turn returns the results to the client, and the client finally display the results. Typical MVC example.
Cheers
Rodney

The tutorial is for ADF BC used with JavaServer Faces.
While the tutorial doesn't cover it, we also support drag and drop development for Swing and visual WYSIWYG layout for Swing panels and windows, too. For a very simple example, watch screencast #4 on my blog here:
http://radio.weblogs.com/0118231/stories/2005/06/24/jdeveloperAdfScreencasts.html
One thing I have noticed is that when using ADF business components, when the app module returns a custom DTO object like the above example, it returns the data in a element structure according to the data control palette.
You don't generally ever need to create your own custom DTO's when working with ADF for use by client UI's. The only situation where can be necessary -- until we simplify this in the JDeveloper/ADF 11g release -- is when you desire to expose custom methods that can return sets/arrays of typed row structures through a web service. However, web services are not involved/required in building 3-tier Swing applications.
When dropping onto a page it does so like a string and doesnt give option to display the data in a read only form etc. Is there anything we need to do, to get the functionality.
It's more of what you don't need to do :-)
Just leverage the active data model that the ADF application module provides. You can read more about it in section 4.5 "Understanding the Active Data Model" of the ADF Developer's Guide for Forms/4GL Developers on the ADF Learning Center at http://www.oracle.com/technology/products/adf/learnadf.html). Your UI's bind to view object instances in the data model, and your UI's are automatically kept up to date without needing to write methods that return data. I short article I wrote that preceeded my writing the ADF Developer Guide content on this topis is here:
http://radio.weblogs.com/0118231/stories/2006/01/26/theAdfBusinessComponentsActiveDataModel.html
I know that when dropping a view object you get this functionality. Also was wondering if we were to pass an object of thios type back to the model it might not give us the rich functionality like input forms, like what Oracle provides if we were to drop a enitity view object.
Just use the active data model and everything becomes totally easy, with no changes required to switch between local or three-tier deployment configurations.
Trying to do everything with hand-coded DTO beans is really going the hard way.
Could you help us regarding this?

Main/Sub Report Passing Parameter

This is a twist on the general passing parameter question:
1. The main report is a detail report based on a stored procedure.
2. The sub report is also based on a stored procedure. This SP calculates the values that will be introduced into a 'table' drawn on the report canvas. The SP consists of a CTE which is a 'reduced' version of the Detail SP used in the main report - to ensure that all the same records are being retrieved between the main and sub reports. Another select, following the CTE, sums the values and makes them available to the Sub Report.
The client has requested the availability to view records where an Activity Date falls within the last full week, the last month, this month, and YTD. The report is available both through Infoview as well as a scheduled version. The client wants to make a selection as to time period through Infoview.
Most other users will be using a printed copy of the 'general' report.
I thought to use the SAVED DATA in SELECTION REPORTS and use Crystal functions to handle this. The SAVED DATA and an optional parameter allowed the user (in Infoview) to change the parameters. This works fine in the main report.
HOWEVER, the sub report needs to update the totals for the groups of properties that are aggregated in the sub report's summary Stored Procedure. Since the time range will, on changing in the Main Report, reflect different counts, I need to be able to tell the sub report what the main report is doing.
The Main report has an Optional Parm ({?Account Open}) which allows the selection of a data range
The SAVED DATA selection uses the values from the parm:
if not hasvalue({?Account Open}) then 1=1
    else if hasvalue({?Account Open}) and {?Account Open}=0 then 1=1
    else if hasvalue({?Account Open}) and {?Account Open}=1 then {Account_open_date_newest}in LastFullWeek
    else if hasvalue({?Account Open}) and {?Account Open}=2 then {Account_open_date_newest}in LastFullMonth
    else if hasvalue({?Account Open}) and {?Account Open}=3 then {Account_open_date_newest}in Yeartodate
    else if hasvalue({?Account Open}) and {?Account Open}=4 then {Account_open_date_newest}in CDateTime (CurrentDate-(DayOfWeek(CurrentDate)+1),CTime(00,00,00)) to CDateTime (CurrentDate+(7-(DayOfWeek(CurrentDate))),CTime(23,59,59))
    else 1=0;
My problem in passing the optional param selection made by the user down to the sub report in order to update the counts.
Any help would be gratefully appreciated! I have included a snap of the Table from tyhe subreport and a snap of the optional parm from the Main Report

Jamie -
Thank you for your reply. I've spent the morning working on the two directions you had provided me with.
Cross tabs: I took one report, created a cross tab for it, and, as expected, it worked as desired. The issue I'm having is where to place it on the report canvas. If I'm correct, the only place where it can be placed is in a header or footer - the sub report is currently residing in Page Header D (there's a lot of suppression and reveals in these reports). The cross tab does not want to be placed there. It's currently living in the Report Header... further, the cross tab occupies page 1; the remainder of the report starts on page two. Not what needs to happen. The current business specification for the report is: Page 1 includes a page header which includes (through iterations a-e) logo, print date info, the sub report showing the summary a series of group headers which in effect creates an index into the various business units. By clicking on a business unit, any groups under it are exposed. By clicking on the sub group, customer data is exposed. As you go to the 'next page', the Summary sub-report is eliminated and the groups under the Business Unit are shown. All of these dynamics are based on section suppression and unhiding based on the user's interaction, which why the placement of the Summary data is important. If you have any hints on managing the cross tab and its placement, I would be eager to hear them.... (btw - the number of rows in the cross-tab can range from 0 to 12. That dynamism is not a problem with the sub report - would it be for the cross tab?)
Parameter Passing: I took one of the reports and (1) ensured that the sub report had the exact same parameter (called Account Open) as the Main Report. (2) ensured that the Saved Data filters in both reports were the same. (In order to do that I had to update the stored proc for the sub report to include an account date field). (3) I then went to link the two reports selecting the Account Open parameter in both the containing and the Fields to Link To list boxes (see the graphic LINK.JOG. This produced no useful result - the Summary showed ALL records- the container report properly showed the count for last full month (see SUMMARY.JPG) (4) I then tried to link a field from the sub report to the Parameter, but only 4 of the six fields from the stored proc's select were displayed. (Prior to this Select there is a CTE which collects the data with a ROW OVER.. PARTITION function):
SELECT
customer_business_unit_name,
account_open_date_newest,
sum (CASE WHEN currentrisk =1 THEN 1 Else 0 End) lowcount ,
sum (CASE WHEN currentrisk =2 THEN 1 Else 0 End) midcount ,
sum (CASE WHEN currentrisk =3 THEN 1 Else 0 End) highcount,
sum (CASE WHEN currentrisk =0 THEN 1 Else 0 End) unknown
FROM    records
WHERE   rn = 1
group by customer_business_unit_name,account_open_date_newest
Only the COUNT fields show up in the Fields box (see the graphic LINKS CHECKED.JPG).
Where have I gone wrong??
Again, thank you for your earlier reply.

Import statement: pass parameter or variable in import statement ??

Hi All..
Is there a way to pass parameter or a variable to a url in the import statement..
I'll be using a url in the import statement, the url will be having a dynamic .rtf file...something like
<?import:http://#server#:#port#/xmlpserver/<mySubTemplate>.rtf?>
where <mySubTemplate> is dynamic..
I've been searching this thread for a while now and ended up close...
Import sub template dynamically
Thanks in Advance..

Have you tried replacing the mySubtemplate.rtf part with a variable, or replace the entire URL using a variable? Try using the same construct from this example in the Report Designer's guide (page 7-14, 10.1.3.4).
In Microsoft Word's Format Picture dialog box select the Web tab. Enter the
following syntax in the Alternative text region to reference the image URL:
url:{IMAGE_LOCATION}
where IMAGE_LOCATION is an element from your XML file that holds the full
URL to the image.
You can also build a URL based on multiple elements at runtime. Just use the
concat function to build the URL string. For example:
url:{concat(SERVER,'/',IMAGE_DIR,'/',IMAGE_FILE)}
where SERVER, IMAGE_DIR, and IMAGE_FILE are element names from your XML
file that hold the values to construct the URL.
This method can also be used with the OA_MEDIA reference as follows:
url:{concat('${OA_MEDIA}','/',IMAGE_FILE)}

Can not see the menu of New Business Components Package in jdeveloper

I am just follow the developer guide.
and when I create the Business Components Package, the guide said that
========================================
In the JDeveloper Navigator, select the OA Project where you want to create your package.
From the main menu, choose File > New to open the New Object Gallery.
In the Categories tree, expand the Business Tier node, and select Business Components (BC4J).
In the Items list, select Business Components Package to open the Business Components Package Wizard. You can also right-click on the OA Project and select New Business Components Package to navigate directly to the Business Components Package Wizard.
=====================================
In fact I can not see the menu about Business Components (BC4J) in the File/new/buisness tier/Business Components (BC4J).
I can only see the File/new/buisness tier/ADF Business Components.
And can not find the "Business Components Package" under ADF Business Components either.
I am using the JDev Extension for OA (p5856648_R12_GENERIC.zip) and EBS 12.0.0.
And I create an OA Workspace and OA Project.
can anyone help?

Pass parameter from request

Hi,
I have 2 pages, in page2 CO2, it passes parameter 'cancel'
processFormRequest{
else if("Cancel".equals(pageContext.getParameter("event")))
pageContext.putParameter("cancel", "Y");
pageContext.forwardImmediately("OA.jsp?page=/company/oracle/apps/xxg2c/goaling/webui/Xxg2cGoalSheetSearchePG",
null,(byte)0,null,null,true,null);
in page1, CO1, I get the parameter 'cancel'.
processRequest{
cancel = pageContext.getParameter("cancel");
Now, if I want pass 'cancel' to processFormRequest of CO1, how should I do it?
thanks
Lei

Lei,
To get the value in co1, there are two alternatives:
1)Pass value in hashmap:
HashMap hmap= new HashMap();
hmap.put("cancel","Y");
pageContext.forwardImmediately("OA.jsp?page=/company/oracle/apps/xxg2c/goaling/webui/Xxg2cGoalSheetSearchePG",
null,(byte)0,null,hmap,true,null);
in page1, CO1 processRequest, you can get it by
cancel = pageContext.getParameter("cancel");
2)Pass param in url itself:
pageContext.forwardImmediately("OA.jsp?page=/company/oracle/apps/xxg2c/goaling/webui/Xxg2cGoalSheetSearchePG&cancel=Y",
null,(byte)0,null,null,true,null);
in page1, CO1 processRequest, you can get it by
cancel = pageContext.getParameter("cancel");

How to get month value from custom calendar without passing parameter from SSRS in MDX query

Could you please throw some light to achieve below requirement?
I need to filter the data between two periods dynamically . The date calendar here works differently(ex:-Date 26-Aug-2014 will fall in period 7 which is last date and 27-Aug-2014 will fall in period 8 and it is first date of period 8),so I cannot go
with system date period/Month. Date Hierarchy is like YEAR,QUARTER,PERIOD ,WEEK and DAY.
I cannot use SSRS for passing parameter. Requirement is to extract last 2 period of data dynamically in Power Pivot with MDX.
Thanks Chandan

Hi Chandan,
You might try something like this
Tail(null:
Extract(
StrToMember("[FYDay].[DATE].&[ + cStr(Format(Now(),"yyyy-MM-ddT00:00:00")) + "]")
*[FYDay].[DateHierarchy].[Day]
,[FYDay].[DateHierarchy]).parent.parent
,2)
What it is doing is multiplying Day by the current date, which returns a set of one date with cardinality of (Date,Day). The Extract is pulling out just the datehierarchy Day. the the Tail() is getting it and the previous day.
Hope that helps,
Richard

How to pass parameter into a source variable of a invoke activity

I'm an new BPELer, I created a invoke activity to submit Oracle Appplications concurrent program, but I don't know how to pass parameter into source variable.
BTW, I have created the mapper file (.xsl) file.
could anyone tell me how to do that?
Thanks,

Hi.
How you start application? I think you send message to webservice(BPEL process is webservice too). So construct message with variable and value.
But I created only processes where input value doesn't matter. I haven't use mapper yet too.

Using Go URL to Pass parameter between dashboard

Hi All,
I am trying to pass parameter using GO URL functionality from one dashboard analysis field to another dashboard.
The navigation is working properly but the parameter is not getting passed, I am not sure why.
The Called dashboard has a analysis which has IS PROMPTED filter attached to it for the passing filter. I tried various ways to make this work
Option 1
In the calling analysis, I am using a Narrative View and inside I have used the below code.
<a href="saw.dll?Go&Path=/shared/MI/_portal/Client-MI&Page=Supplier%20Detail%20Tab&Action=Navigate&P0=1&P1=eq&P2=Dim%20Supplier.Supplier%20Name%20Current&P3=1+%22STR%20LTD%22"> @2[br/]
This one navigate but filtering is not happening
Option 2 (My first preference will be this option)
Also I tried to provide custom Data Format under the column Properties
[html]"<font class="nav" onclick=\"JavaScript:GoNav(event, '/shared/MI/_portal/Client-MI/Supplier Detail Tab','Dim Supplier','Supplier Name Current','"@"');\">"@"</font>
This ends up giving error
Type mismatch of catalog object /shared/MI/_portal/Client-MI/Supplier Detail Tab -- expected , got .
Error Details
Error Codes: UVWDR6UA
Also, both the tabs (Called and Calling are under the same Dashboard)
Can anyone please let me know, were I am making mistake. I tried refereeing Oracle documentation but still no result.
Thanks

Looks like you've got it almost right - just an extra unneeded "
<a href="two.jsp"?ant=<%= ant %>"><%=antName%></a>
which should render on the page as something like
My Ant Task
When you click the link, it should pass that parameter, and you can get it via request.getParameter().

Can Any one help me...
Sincerly
Amol

For your first question can you please be a little more clear as to what you are referring to? I am not familiar with an action button for the parameter pages.... what I can tell you is that we don't have any jsp code for the viewer controls, all of that is generated dynamically at runtime. We do have a viewer SDK that you can use to set properties on the viewer; information about this can be found in the [Developer Library|https://boc.sdn.sap.com/developer/library] in the Viewer SDK documentation book.
For your second question, I assume you are referring to generating a viewer page from a report in Crystal Reports for Eclipse. You will need to uncomment the viewer code (for some reason when the page is generated, the viewer code has block comments surrounding it). You will probably want to make sure the parameter code is uncommented as well.
In addition to this, there is a helper file called JRCHelperSample.java that contains all of the helper methods for the automatically generated viewer page. This can be modified in whatever way you wish to suit your needs.
