Variable one to one
Hi,
1) Is it possible to have the class indicator in a variable one to one mapping set to a function call, or a pl/sql expression instead of a field?
2) I am trying to use the workbench to create a variable one to one but the reference descriptor dropdown does not show anything.
Thanks!

1 - You could use custom SQL or stored procedures in your queries to read the source object of the variable 1-1 and potentially provide the indicator value from a function, but this would be very complex. You would probably be better off having an indicator field, or not using an indicator (it is optional). Perhaps some more information on what you are trying to do?
2 - A variable 1-1 mapping is a 1-1 relationship from the source descriptor to one of several different classes that share a common interface. You must have a common interface between the target classes and define an interface descriptor for the interface in the Mapping Workbench.

How to use bind variable value of one VO as initial value for other VO row?
JDeveloper 10.1.3.3, ADF Faces, ADF BC
Hi,
I have two View Objects: one read only with several bound variables and another editable entity based. Correspondingly there are two ADF Faces pages: first contains search form based on the read-only VO and second create form based on the editable VO. The search form has several hidden fields for some of bound variables because they aren't edited directly by user. These fields are updated with PPR when user selects other search criteria from LOV.
There is a command button in the first page that navigates to the second form. Is there any way to transfer values of bound variables from the first VO to the second VO as initial values of the new row?
I tried to set custom controller for the second page and retrieve search criteria values from request parameter map but values from hidden fields are missing. I think because that these fields are updated by PPR. Of course I can add custom action method to the navigation button and in the method put these values to request parameter map but I hope there is better solution.
Thanks,
MariusTo summarize, given a bind variable value for one VO, on creating a row in a second VO, for 1 of the attributes of the second VO, you want to use the first VO's bind variable value. Correct?
A potential solution ADF BC driven:
1) Ensure you have an AppModuleImpl for your AM
2) Ensure you have a ViewImpl for your 1st VO (where the bind variable will exist) - lets refer to that VO as "Alpha"
3) Ensure you have a ViewRowImpl for your 2nd VO (the one you want to default the value in) - lets refer to that VO as "Beta"
4) For your first VO "Alpha" create the bind variable (say pValue)
5) In your second VO "Beta" ViewRomImpl add following code:
@Override
protected void create(AttributeList attributeList) {
super.create(attributeList);
AppModuleImpl am = (AppModuleImpl)this.getApplicationModule();
String someValue = am.getAlphaView1().getpValue();
setSecondVOAttr(someValue); // change this code to whatever your setter is for the field you want to initialize.
}Hope this helps. Let us know how you go.

Variable sharing from one class to another??
Hi!!
Suppose two classes, one class extend from JFrame and another
from JDialog.I want to share the variable of Second one(extending JDialog) into firstone.How can I get this? please help me.For example:
In JFrame class...

someVariable = theDialog.getVariable();
In the JDialog class, add the getVariable method. -
Variable One to One - difficult question
Hi
I am using a Variable One to One mapping but TL is not using the class indicator information to produce the correct SQL and I wonder what I am doing wrong.
I have the following simplified database design:
Users:
userId (pk)
Applications:
applicationId (pk)
ServiceProviders
serviceProviderId (pk)
applicationId (fk)
Services
serviceId (pk)
serviceProviderId (fk)
UserEntities
userId (pk, fk)
entityId (pk)
entityTypeId (pk)
The Id values for different entity types are mutually exclusive - there can be a serviceId #1 and a serviceProviderId #1.
I have several classes that implement an Entity interface (Application, ServiceProvider, Service), and a UserEntity class containing a reference to a User and an Entity.
In the descriptors for classes implementing Entity I have a one to many mapping to UserEntity, with a table reference constructed in MW, and a single source / target field pair of e.g. entityId - applicationId. In the UserEntity descriptor I have a one to one mapping to User and a variable one to one mapping to Entity. This contains a Class Indicator based on the entityTypeId field, and values for each class implementing Entity have been entered.
It seems that when I insert a new UserEntity instance, this class indicator value is used to supply a value for the entityTypeId field. When I access the userEntities collection from a User instance, the class indicator is used to instantiate the correct kind of Entity. But when I access the userEntities collection from an instance of the an Entity class like the Application class, the EntityTypeId is not specified in the SQL generated:
ServerSession(30932017)--Connection(24156236)--SELECT ENTITYID, ENTITYTYPEID, USERID FROM USERENTITIES WHERE (ENTITYID = ?)
bind => [1]
#### I would expect 'AND ENTITYTYPEID = ? ..... bind => [2]' here #####
I would expect the class indicator info to be used both ways, when determining what class to instantiate for the variable one to one, and also to make the query specific to that class when an instance is being used.
Many thanks if you can shed some light on this. Perhaps I have to use an API method as demonstrated in this post how can i map this?

Thanks for your reply.
I have a similar NullPointerException on the validateNode method. I slavishly followed your code example - hope it was right :), so will raise this with Oracle support.

How to pass a variable more than one values?
How to pass a variable more than one values?
You can't.
During 1 session, 1 ODI variable can have only 1 value at a time.
If you need more than 1 value, you will have to do somethink like a loop inside your package, and refresh the variable value each time. -
Hi I have a print layout design form designed by someone else. I would like to modify it and have noticed that it uses a variable number for one of the fields. How can i tell what the variable definition is for this variable? thankyou
Judi - a suggestion as I got burnt on this area - be VERY VERY careful when using variables in the Print Layout Designer (PLD). I walked into a customer's office and said the information she wanted could be included as part of the results with PLD by using the variables displayed in the system. A bit embarassed when the results came out funky and certainly not what she was looking for.
I did an extensive amount of research and submitted a ticket to SAP, and here is their reply (verbatim from the ticket):
"The fields in the other report that are showing results 'Text Type Field'
are harcoded or system fields and they only can be used by our
development team...
<u>Variables are generally not supported by us as they can be subject to
change in patches or upgrades. Please check Note 723783...
We do not guarentee that the displayed Variable Numbers are valid
and will print the correct information...</u>
Adding Variables can as well corrupt your Layout in General. Therefore
we do not encourage you to try to add your own Variables..."
By "displayed variable numbers", SAP Support was referring to some numbers I had copied down from the forms themselves and passed on to SAP asking why they were not as documented. But guess what - the variables did NOT print the same info in the PLD as what was displayed on the system! It turned out to be a real mess.
I am especially worried about the statement that variables can change in patches or upgrades and wonder if there will be some work to be done for when any PLD was modified? -
Variable one to one mapping question
I'm trying to create a variable one to one mapping using an interface with two implementing classes. The problem that I have is that I have two different values in the class indicator column that I wish to map to the same class. Mapping workbench doesn't let me do this. The MW documentation discusses using unique primary keys by leaving the class indicator blank. However, i'm using 9.0.4.8 and this doesn't appear to work as I get exceptions at runtime.
Is there anything along the lines of the inheritance classextraction method for interfaces? Any suggestions for how to go about this?
Thanks in advance,
JonathanHi Jonathan,
This use case is not supported in the Workbench. You will have to define an After Load Method in the workbench and add the indicator->class mappings in code. I am not positive on how this is handled in the runtime. Which indicator would be used when writing, maybe only supported for read-only mappings, or possibly not supported at all? Someone from the runtime team can respond about this.

How to query objects on variable one-to-one relationship
Hi,
I have a situation here:
Application (APPLICATION table) has many payoffs (Payoff table); Primary key of application is the foreign key of payoff.
Payoff has disbursement, such as check(check table), directDeposit(directDeposit table) or Wire(wire table), which is variable one-to-one relationship. They share the same primary key
The query I need to run is to search application based on check number, How do I construct a query to perform this kind of search?
Thanks
Hao
[email protected]Hi Doug,
Thanks for all your help. But I guess I still need more details from you to help me understand the solution.
First of all, I want to make sure I make my case clear
Application (application table, pk: uniqueAppId) has many payoffs (Payoff table, pk: payoffId);
Payoff object has variable one-to-one mapping to Disbursement object, which is a abstract super clss for following objects:
Check(payoff-check table, pk: payoffId)
DirectDeposit(payoff-deposit table, pk: payoffId)
Wire(payoff-wire table, pk: payoffId),
The query I want to run is to get me back an application for a particular check number
From you email, first I thought "check" is a object, then your sample code showed it is a string. So I am kind of confused. The document you pointed seems not reflect my case. I wonder it is because I didn't present my case clear the first time.
Looking forward to your further help

i am working on variable one-to-one mapping. i am unable to figure out how to work on it. can anybody provide an example on how to implement it from java and toplink perspectives.
Thank you. I have gone through the links. i used class indicator field method. I am still getting error saying
"Exception Description: Missing descriptor for [class java.lang.String]. Verify that the descriptor has been properly registered with the Session."
My code and table structure is as below.
Interface - VariableOneToOne
Implementation classes: Phone and Email
Table Structure:
Employee Table:
ID (PK)
Name
TYPE (mapped as variable one-to-one)
C_ID(FK to eid and pid)
Phone Table:
pid (PK)
phnumber
Email Table:
eid (PK)
emailaddress
"TYPE" is of string type. "Phone" or "Email" is sent from this attribute. Toplink instantiates the respective class from the configurations specified in the variable one-to-one mapping of "TYPE" attribute in workbench.
The classes and interface code is as below:
Inteface:
package com.cts;
public interface VariableOneToOne {
public int getId();
public void setId(int id);
Employee Class:
package com.cts;
public class Employee2{
protected int id;
protected String name;
protected String type;
protected VariableOneToOne phone;
protected VariableOneToOne email;
public Employee2()
this.id = 0;
this.name = null;
this.type = null;
this.phone = null;
this.email = null;
public int getId() {
return id;
public void setId(int id) {
this.id = id;

return name;
public void setName(String name) {
this.name = name;
public String getType() {
return type;

this.email = email;
public VariableOneToOne getPhone() {
return phone;
public void setPhone(VariableOneToOne phone) {
this.phone = phone;
public void setType(String type) {
this.type = type;
Email Class:
package com.cts;
public class Email2 implements VariableOneToOne {
protected int id;
protected String email;
public Email2() {
this.id = 0;
this.email = null;
public String getEmail() {
return email;
public void setEmail(String email) {
this.email = email;
public int getId() {
return id;
public void setId(int id) {
this.id = id;
Phone Class:
package com.cts;
public class Phone2 implements VariableOneToOne {
protected int id;
protected String phone;
public Phone2()
this.id = 0;
this.phone = null;
public int getId() {
return id;
public void setId(int id) {
this.id = id;
public String getPhone() {
return phone;
public void setPhone(String phone) {
this.phone = phone;
Please advice on resolving the issue.
Thanks in advance. -
One to one mapping question -- can I just map a lookup field for queries?
I have a table with a state code. I'd like to have a "virtual lookup" on the java class to a region table. I.e., this java class "studies" has a state code. I can map a one-to-one to the descriptor class that has the ref table, but I'd like to have a property in the java class pre-mapped to the "region" field in this lookup so for querying i can just use:
ReadAllQuery q = new ReadAllQuery();
q.setReferenceClass(study.class);
q.setSelectionCriteria(new ExpressionBuilder().get("Region").equal(Region));
to get all the studies for a particular region.
am I going about this wrong? or do I have to get the reference table descriptor fromt he one to one map and do something different?well,on the way home last nite, I realized I'd had a complete brain fart. I've done this before. I just set up a 1-1 map between descriptors and then built the query like this:
q.setSelectionCriteria(new ExpressionBuilder().get("refFPO").get("FPO_NO").equal(FPO));
You can get the pointer to the "refFPO" which is the the descriptor mapped 1-1, then appended the column you wish to get.
I still went ahead and amended my class to include a read-only, non-toplink mapped attribute "FPO" which just gets the reference variable pointing to "refFPO.getFPO_NO();

public static void main(String args[])
test t = new test("Title");
t.setSize(900,470);
t.setVisible(true);
t.setResizable(false);You are sleeping the thread used to perform the repaint.
Calling repaint only marks a component as needing painting, and AWT will paint it later. If you continue to loop in the mainthread then you will not see the changes.
You have to move your loop to another thread. -
How to read the row of resulted table one by one
Hi,
My query is displaying n no of rows in resulted table.Is there any way to read the row one by one and pass the value of attribute in other variable.
If anybody knows then please let me know.
thanks

read the VO using RowSetIterator
OAViewObject reqLinesVO = (OAViewObject)am.findViewObject("VO");
if(reqLinesVO!=null)
int fetchedRowCount = reqLinesVO.getFetchedRowCount();
RowSetIterator reqLinesIter = reqLinesVO.createRowSetIterator("reqLinesIter");
if (fetchedRowCount > 0)
reqLinesIter.setRangeStart(0);
reqLinesIter.setRangeSize(fetchedRowCount);
for (int i = 0; i < fetchedRowCount; i++)
OARow row = (OARow)reqLinesIter.getRowAtRangeIndex(i);
String getattr=(String) row.getAttribute("Attribute14");
// Always close the iterator when you're done.

Hi,
I have an object A having one to one relation with object B.
Object A has these fields
id - long
name - String
order - ValueHolderinterface (for object B)
object B has these fields
order_id - long
order_type - String
I am using ExpressionBuilder to query all objects of type A having order_id =some value say 1.
ExpressionBuilder builder = new ExpressionBuilder();
Expression exp=null;
exp=builder.get(?).likeIgnoreCase("1");
What should I use as attribute name, that is in the place of "?" for querying based on order_id.
Appreciate any help.
Thanks
PriyaHi,
Assuming the fields you've given are the variable names in the class (as opposed to the database columns), it'd be:
exp = builder.get( "order" ).get( "order_id" ).equal( "1" );
And then you'd query with A.class as your reference class, like
session.executeQuery( A.class, exp );

I have noticed over the past week that after taking a picture with my iPhone 4S (OS7.0.4) the picture is in the camera roll but when I try to view it's blank. I can take multiple pictures but 90% will all end up blank.
