Create dynamic table using pojo data control

What are the options we can in order to create dynamic table columns based on pojo data control?
We have a class A and there are some attributes say A.x, A.y, A.z
Within class A, we have a collection of class B and has attribute say B.k
Within class A, we have a collection of class C and has attribute say C.j
Every instance of class A has same number of instances of class B
Every instance of class A has same number of instances of class C
We would like to display a table like this
A.x, A.y, A.z, [B.k, B.k, ...], [C.j, C.j, ...]
How should we do that?
Thanks

How to create dynamic table using POJO based DataControl

Hi,
I'm using JDeveloper 11.1.1.5.0. I'm not using ADF BC.
I've a requirement to display the Dynamic table in my search page.
In our product we are using POJO based Data controls.
I created a task-flow and page fragment. I tried to create the dynamic table by drag-drop of searchResults from my Data control, I see the option for Read-Only Dynamic Table, but when I select this option, I don't see anything happening.
Does the Dynamic Table work with POJO data controls?
Any inputs would be helpful.
Thanks
Ravi

First U have to crate Extended View Object to your actual View obj.
Now take Page with Panel Splitter ,on First facet drag View obj as table and on second Facet Drag Extended View Obj as table.On page loading U have delete all rows from Extended View object.And then u have write bean code on button click to get current select rows from above view objct,and for Filter rows from Second View obj according to selection of rows from first view obj...

Hello everyone,

I have a methodAction Binding defined for a JSFF. I am executing this methodAction in a managed bean. When doing so I have the following exception:

This methodAction calls a Data Contol based on a POJO which is using a JAX-WS Proxy. This Data Control POJO is packaged in a separate JAR file named ServicesProxy.jar.
Both ServicesProxy.jar and the ADF application using it are deployed as two distinct shared libraries used by webcenter portal application.
An important information is that the error does not happen when debugging the ADF application on my IntegratedServer. The error happens only when deployed as a shared Lib used by webcenter portal application.
This jar file ServicesProxy is used by other applications within our portal, so I think that the data control is properly created.
Do you have any idea what could be the cause of such error?

How to cause POJO data control to use custom base ViewObject class

ADF 11.1.1.4
We have a POJO data control that displays data in a table. We can filter the table using the column filters and this performs in-memory filter. If an exception occurs I see that it is using a ViewObject for the in-memory filtering because this shows up in the stack trace.
oracle.jbo.server.ViewObjectImpl.rowQualifies(ViewObjectImpl.java:2811)
It uses DCDataVO which extends ViewObjectImpl
We have a Custom base view object defined that all our normal view objects inherit from, defined in Project Properties/BC/Base Classes
Is there any way to make the DCDataVO also extend from our Custom View Object that inherits from ViewObject so that we can override methods? For example if I wanted to customize the rowQualifies method.
In DCBeanDataControl.Java I see where it actually gets created.
vo = DCDataVO.createViewObjectFromDef(vdef, this, getApplicationModule());

So you have already overridden then rowQualifies() method in your custom base View Object ? Are you calling super in that ?
Cheers

Any Examples of using ActiveCollectionModelDecorator with POJO data control

Are there any Examples of using ActiveCollectionModelDecorator with POJO data control in any of the sample packs?

OK, here's an quick example. Create a new Windows Forms application and add a ScatterGraph and a Label to the form. Add a cursor to the ScatterGraph, then add the code below to the form. This generates 50 random data points when the form is loaded and plots them, then uses the cursor's AfterMove event to display the current X and Y positions in the label. Here's the code:
Private Sub OnFormLoad(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
Const dataLength As Integer = 50
Dim xData(dataLength - 1) As Double
Dim yData(dataLength - 1) As Double
Dim rnd As Random = New Random
For i As Integer = 0 To dataLength - 1
xData(i) = i
yData(i) = rnd.NextDouble() * 10
Next
ScatterGraph1.PlotXY(xData, yData)
End Sub
Private Sub OnAfterMoveXYCursor(ByVal sender As Object, ByVal e As NationalInstruments.UI.AfterMoveXYCursorEventArgs) Handles XyCursor1.AfterMove
Label1.Text = String.Format("({0}, {1})", e.XPosition, e.YPosition)
End Sub
Hope this helps.

How to create Dynamic Table Control

Hi
How to create Dynamic Table control , The field names and values to be displayed in table control are to be fetched from Add-on Tables.
Regards
Prasath

Hi Jonathan,
Actually the columns to be displayed are not constant . It will be increased based on the database values, Anyhow it will not exceed 100.
Please confirm my understanding.
1. In this case I have to create 100 custom columns and make it visible / invisible based on my requirement and I can set the title at runtime.
2. How can i assosicate / reassociate the datadictionary reference for the columns that i use. Because I need to show the search help values for the
dynamic columns.
Your opinion on this will be helpful.
Regards
Prasath

Problem with editable combo box and creating dynamic table values using js

Hai
I have used jquery.jec.js to make my dropdown list as editable... I need to create dynamic table values on the onChange event of dropdown using javascript.
Now am facing the problem in it...
I am getting duplicate rows in the table... think(assumption) this jquery.jec.js is calling the dropdown again creating duplicate values...
Please help me out.... Any help is appreciable... Thanks in advance

Thanks elOpalo, for your valuable response....
I have found the correct way of doing.
Before i had my code like this,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>test</title>
<script type="text/javascript" src="js/jquery-latest.js"></script>
<script type="text/javascript" src="js/jquery.jec.js"></script>
<script type="text/javascript">
$(function(){
$('#list').jec();
function giveAlert(){
alert('hello');
</script>
</head>
<body>
<form>
Combo Box:
<select id="list" name="list" onChange="giveAlert();">
<option value="1">one</option>
<option value="2">two</option>
</select>
</form>
</body>
</html>
Now i have changed as the following,
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=ISO-8859-1">
<title>test</title>
<script type="text/javascript" src="js/jquery-latest.js"></script>
<script type="text/javascript" src="js/jquery.jec.js"></script>
<script type="text/javascript">
$(function(){
$('select.combo').jec();
$('select.combo')
.change(function() {
alert($(this).val());
}).change();
</script>
</head>
<body>
<form>
<table>
<tr>
<td>Combo Box:</td>
<td><select class="combo"><option value="b">banana</option><option value="a">apple</option></select></td>
</tr>
</table>
</form>
</body>
</html>
The problem is with the function i have called on the onChange Event.. Now i have defined it inside the jquery function of dropdown to make it as editable...

Hi Sarbjeet,
The code is working fine, when i use in wddomodify view method without button click on first time.( I checked this by creating another component). But I am creating dynamic table when click on button(view contains one button initially), for this i created two attributes FLAG OF TYPE wdy_boolean and count of type int1. and in button action i write this code :
DATA lo_el_context TYPE REF TO if_wd_context_element.

Managed Beans vs. POJO Data Control for sharing data

Hi,
I am currently using JAX-WS proxy client and POJO Data Controls to retrieve data from web services. This data needs to be shared across users. Normally I would use application scoped managed beans for this, but since I prefer using data controls and the binding layer, would using static POJO Data Control classes achieve the same thing?

Hi,
Data Controls don't exist across user sessions so in your use case use a managed bean in application scope. If you want to make this available from a Data Control
- create a POJO
- Use EL in the POJO to access the managed bean
- Create a DataControl from the POJO
This way the Data Control exposes the data as an API but itself always reaches out to the managed bean as a data store/cache

Using UCM data controls in ADF application

Using *.6 Jdeveloper/UCM/Protal Application/UCM
Calling all the experts in Webcenter/Spaces/UCM/ADF.
We have a requirement to design search inteface for Documents stored in UCM for Webcenter Portal and Spaces application.
Our approach is
Design simple ADF application (no security/templates)
Bounded task flows using fragments.
Framents to use UCM data controls (provided by oracle)
UCM data control definition is extended to use custom metadata.
package the application.
Added as ADF library jar to portal application
Added as Shared Library to Spaces application.
Question.
Is this approach sound?
Does UCM data controls provide all the functionality, for example if we want to read a option list for custom metadata or need custom metadata in return table?
Can we add other methods to UCM data control provided by Oracle or should we create different one?
Is there good documentation for such requirements. We have acces Webcenter developers guide which throws some light on UCM data controls.
Let me know if more clarity is needed...
Regards

Hi.
One of my last components was a custom "Document Explorer" and I used for first time JCR Data Control (Custom UCM Data Control provided by Oracle).
Sharing my experience I did something similar to you:
1) Create a ADF Bounded Task Flow and test it individually.
2) Add generated ADF JAR Library to WebCenter Spaces shared-lib.
3) Add your Task Flow to Resource Catalog.
Challenges that I found using custom Data Control:
1) When items retrieved are content/files all custom metadata can be retrieved OOTB.
2) When retrieving folders don't provide custom metadata like files. I used RIDC with JCR Data Control to provide all the information relative to folders. If you don't need more information about folders than the name, URI and icons then is OK :).
3) Using JCR Data Control registers in DataControls.dcx UCM Connection name used when generate JCR Data Control. After deploy your ADF JAR Library in WebCenter Spaces you'll have problems if you don't have a WebCenter Content Connection created with the same name. (Not talking about export UCM Connection with ADF JAR Library, Data Control uses a Connection name by itself :)).
I added extra functionallity with RIDC (not extending JCR Data Control).
I hope this help you.
Regards.

How to use multiple data controls in a single JSF page

Hi,
I am using Essbase Data Control to in my project to get Essbase Cube data into ADF table/Pivot Table.
Suppose if [Item] dimension has this hierarchy [category] -> [Segment] -> [Brand] -> - [Item]
I need to display Category in one column and Segment in the next Column and [Brand] in the another column.
Different types of Category, Segment and Brands should display as table data(data values).
Using MDX query I can not print [Item] hierarchy in different columns..so I am planning to use multiple data controls.
Could any body help me to get the solution.

Hi,
sounds like you want to try the Pivot table
http://download.oracle.com/docs/cd/E21764_01/apirefs.1111/e12418/tagdoc/dvt_pivotTable.html
I don't think that multiple Data Controls is the solution to the problem

How to create a table using subform if lifecycle designer 7.1 not availabl

hi,
plis tell me how to create a table because i am using adobe lifecycle 6.1 and in the library
there is no object for table..
also tell me that if i have adobe lifecycle designer then which is better option and why?
use table from library directly or create a table using subform...

Hi Sweta,
Create the interface attributes of type string and xtring type.
Create node in the context of type graphics. bind the interface fields to the graphic node context element properties -
Graphic content, field of xzstring type and mimetype to be string/any char data type of suitable length.
In layout drag and drop the image field and bind it to the graphic element.
In yoour report programme-
do the code as berlow to pass the graphic data -
<i>CALL METHOD cl_ssf_xsf_utilities=>get_bds_graphic_as_bmp
EXPORTING
p_object = 'GRAPHICS'
p_name = '<mime type graphic name>'
p_id = 'BMAP'
p_btype = 'BCOL' "BMON if monochrome
RECEIVING
p_bmp = w_binary
EXCEPTIONS
not_found = 1
internal_error = 2
OTHERS = 3.
IF sy-subrc <> 0.
MESSAGE ID sy-msgid TYPE sy-msgty NUMBER sy-msgno
WITH sy-msgv1 sy-msgv2 sy-msgv3 sy-msgv4.
ENDIF.</i>
in the call <form function module>
pass the inerface values for
xstring (graphic field) to be w_binary (import parameter of the previous method)
and mime type to be 'image/bmp'.
This would work.
Hope fully you may be able to see a tutorial on this soon ;).

Create new table using LABSQL

Hi, how can i create and delete a table in MS Access using labSQL?

Do you have Databse Connectivity Toolkit or SQL Toolkit?
Here are some examples you can look at:
The attached VI (in AccSQL.zip) creates a table and inserts data. It demonstrates the use of Access syntax. It requires LabVIEW Database Connectivity Toolset.
Inserting Data in LabVIEW from Table Create Using Access 97 SQL Toolkit Syntax
SQL Toolkit for G Reference Manual
You should also look under SQL examples that ship with the toolkit.

Create a table and upload data in MS ACCESS from SAP ABAP programming?

Hi All,
How to create a table in MS ACCESS database and Upload SAP database table data into MS ACCESS table using ABAP programming?
Explain: My client requirement is " If he/she runs a ABAP Program, that will create a table and upload data into MS ACCESS Database table in background. "
Could you please give the solution or code? I know the program RIACCESS and I went through the SAP Note 583698.
Is this only solution for this? Or Any other possibilities?
Please give me solution.
Thanks in advance.

Hi,
It is not possible to create tables in a non SAP schema from inside SAP.
The SAP-Oracle license also does not allow you to create the table (see note 581312):
the following actions, among other things, are therefore forbidden at database level:
Creating database users
Creating database segments
Querying/changing/creating data in the database
Using ODBC or other SAP external access methods
Please refer following link,
[Ckick Here|https://www.sdn.sap.com/irj/servlet/prt/portal/prtroot/com.sap.km.cm.docs/oss_notes_boj/sdn_oss_boj_erq/sap(bD1lbiZjPTAwMQ==)/bc/bsp/spn/scn_bosap/notes.do]
You can also do it by LSMW,
If you are using Access 97, you can download directly into an access
database from SAP. See program RIACCESS for details. You have to establish
an RFC destination PS_ACCESS_1 and 2.
There are then a couple of function modules. Go to SE37 and put in
msaccess and hit PF4.
The following is from the readme file: sapgui/ps/readme.sap
For the MS-Access interface SAP delivers 4 files:
WDPSASTR.EXE This is an RFC server program that is called by SAP R/3
(PS module). This program creates a MS Access database. The structure
information of the tables is transferred from R/3. In addition to
these tables a table named DDIC is created. This table contains the
structure information and should in no case be modified or deleted.
WDPSATAB.EXE This is an RFC server program that is called by SAP R/3
after WDPSASTR. This program filles the tables of the database with data.
There must not be made any changes of the structure of
the tables between the calls of WDPSASTR and WDPSATAB.
WDPSAZET.EXE This is an RFC client program that triggers work/time
confirmations in the PS module of SAP R/3 (like transaction CN27 Collectiv
confirm).
WDPSAMAT.EXE This is an RFC client program that triggers material
confirmations in the PS module of SAP R/3 (like transaction MB1A - Goods
Please also refer following links,
[Click here|Upload data from MS Access tables, to SAP tables.;
Before using the program "RIACCESS", you need to install the PS utilities, which are part of SAPGUI install CD.
It is available in the "SAPGUIPS directory".
Then do the followings :
1. Select transaction code SALE -> Systems in network-> Define RFC Destination.
2. You will need two RFC destinations (TCP/IP connections for the front-end workstation).
Setup the two RFC destinations PS_ACCESS_1 and PS_ACCESS_2 and you'll have to get them to point to
wdpsastr.exe and wdpsatab.exe respectively.
3. Then execute RIACCESS and choose PS_ACCESS_1 to generate access tables.
The system must also be able to access the RFC-DLL files (librfc2.dll, librfc3.dll, librfc4.dll, librfc5.dll, librfc6.dll, vrfc.dll).
Please note that Access only supports tables with up to 255 fields.
