Entity object attribute with a list of objects

Does anyone know how one sets up an entity object that has an attribute with a list of objects as the type? (assuming that's supported)
as in:
CREATE TYPE phones AS VARRAY(10) OF varchar2(10);
Create table suppliers (supcode number(5),
Company varchar2(20),
ph phones);
The SOA Suite in jDeveloper (new Entity Object/attributes etc) has an ARRAY that can point to REF or OBJECT. Neither work. When I try to Create DB Object later from the Entity Object I've created I get an invalid type.

What you suggested about "validation codes on the VO" is not written on the ADF Documentation.
I try to blindly/strictly follow best practices (particularly on Validations, using Declartive and/or built in validators) on most ADF documentation and blogs but there are many scenarios on coding some large ADF projects that I think must veer away from the best practices stated on the documentation or maybe add new rules on the documentation depending on how complex an ADF project would be.
I religiously followed best practices stated on the documentation to use Entity and Attribute Validators when performing validations. What I did was i had created lots of Custom Validators (by implementing JboVAlidatorInterface interface) for each of the attributes on an Entity Object that need validated. So those validator is valid only for one attribute, its not reusable. And those validation codes either have reference to a ViewObject or call some PL/SQL procedure. So at some point are codes became messy.
Ultimately the whole project became harder to manage when the codes became large. Now I am trying to refactor the whole application by separating it into project/package and I am hoping to do it with little Re-coding as possible.
Hope to get your opinion on this one.

Anton

Populate object form with already provsioned resource object's data

OIM Version:
9102 BP19
Scenario:
We have to pre-populate resource object (ModifyObject) form fields with already provisioned resource object (ProvisionedObject) form fields which can be multi-instance resource.
This provided data will be used modify the already Provisioned resource object data (same ProvisionedObject). And this needs to be handled with approval workflow.
Approach:
We will use selected ProvisionedObject’s process instance key on web page in resource object pre-populate adapters. And using that process instance key we will fetch already provisioned resource (ProvisionedObject) object’s data.
Issue:
Not sure how can we pass the process instance key from WEB_PAGE to OIM_RESOURCE_OBJECT’s pre-populate adapter.
Any pointers towards the solution will be appreciated.

My suggestion is...
At the time of raising the request, use userKey and in the code use getObjects() to retrieve the provisioned resource object information. Here you can retrieve Process Instance Key of the Provisioned resource and then retrieve the process data. So at this point you will have all the required data of the provisioned resource which can be returned to the object form field.
This is one approach. Experts may throw more pointers.

Unable to map/get Attributes with import of LDIF Object Class

Hi All,
We are trying to take import of Customized Object Class and Attributes into OID through LDIF.
LDIF import command is:
./ldapadd -p 3060 -h myhost -D "cn=orcladmin" -w Ac123456 -f xyzObjClass.ldif
LDIF contents are:
dn: cn=subSchemaSubentry
changetype: modify
add: objectclasses
objectclasses: ( 1.3.6.1.4.1.1436.2.46 NAME 'ProviderObjClass' SUP ( organizationalPerson $ person $ top ) STRUCTURAL MAY ( attr1 $ attr2 ) )
Note: attr1 and attr2 are already imported into OID.
Result: We are able to create Object Class and also able to inherit Super Class. But we are not able to map the attributes to our Object Class.
Can anybody help me in importing ?
Thanks & Regards,
Newbie

Again, I don't work with Java and you should ask Java-related question in Flex (or Java) forum.
Java or not - you need to package your server side language specific object into something that AS understands (text, XML, AMF object) and load this data into AS via, perhaps, URLLoader. Or you can open socket. Then you parse this data with AS3 code in SWF.

Nested tags with a List of Objects

I'm having trouble getting nested tags to work. Here's an example:
My form has a List that contains a Bean called Car as well as a getter and a setter. The Car Bean has three String attributes: color, model and manufacturer. Getters and setters are present.
When I navigate to the form, my Action class creates a single Car and adds it to the list: when the page loads I am presented with three text fields representing my Car bean. Good.
However when I enter some text into the fields and hit the save button I get the following error:
Error 500: BeanUtils.populateI've read a bit about nested tags but still I can't figure out what exactly I'm doing wrong.
Here is a small sample of the JSP code;
<html:form action="/addCar.do">
<nested:iterate name="carForm" property="carList" type="com.foo.bean.CarBean">
<nested:text property="color"></nested:text>
<nested:text property="model"></nested:text>
<nested:text property="manufacturer"></nested:text>
</nested:iterate>
</html:form>Should I be doing something else to properly use a nested tag? Please let me know if more details are required.
Thank you,

I am using crystal reports to show names of a bunch of people. insted of each name comes form different function inside the oracle package, I would like to have a single function with an array of names so that I can return it easily
eg; board member 1 (from function 1)
board member 2 (from function 2)
board member 3 (from function 3)
I should get something like board member n(from a single function that has n number of members) , so that its easy for managing the list later and reduce the code
This sounds so silly, but i am new to both crystal and pl/sql....
please help

Problem with object view with primary-key based object identifier

Hello!
I met such problem.
t1 is persinstent-capable class:
class t1 : public PObject { .... };
T1OV is object view, based on object table T1OT
I1 is primary key of the table T1OT.
Next code:
t1* t = new (conn, "T1OV") t1(...);
conn->commit();
try
t->markDelete();
conn->commit(); // exception throws here
Works fine if T1OV defined as:
create view t1ov of t1 with object identifier default
as select * from t1ot;
And throws an exception
"ORA-22883: object deletion failed"
if:
create view t1ov of t1 with object identifier (I1)
as select * from t1ot;
Such problem also occurs when object view is based on relational table/view (OID is primary-key based).
Also it occurs when
t->markModified() used insted of t->markDelete()
I am using Oracle 9i second release for windows and
MS VC++
Thank You

You can specify constraints on views and object views. You define the constraint at the view level using the out_of_line_constraint clause. You define the constraint as part of column or attribute specification using the inline_constraint clause after the appropriate alias.
Oracle does not enforce view constraints. However, operations on views are subject to the integrity constraints defined on the underlying base tables. This means that you can enforce constraints on views through constraints on base tables.
Restrictions on View Constraints
View constraints are a subset of table constraints and are subject to the following restrictions:
You can specify only unique, primary key, and foreign key constraints on views. However, you can define the view using the WITH CHECK OPTION clause, which is equivalent to specifying a check constraint for the view.
Because view constraints are not enforced directly, you cannot specify INITIALLY DEFERRED or DEFERRABLE.
View constraints are supported only in DISABLE NOVALIDATE mode. You must specify the keywords DISABLE NOVALIDATE when you declare the view constraint, and you cannot specify any other mode.
You cannot specify the using_index_clause, the exceptions_clause clause, or the ON DELETE clause of the references_clause.
You cannot define view constraints on attributes of an object column.

How to reference the Parent view Object attribute in Child View object

Hi , I have the requirememt to generate Tree like struture to display Salary from joining date to retirement date in yearly form.I have writtent two Pl/SQL function to return parent node and child nodes(based on selected year).
1.First function --> Input paramter (employee id, retirement date , joining date) --> return parent node row with start_date and end_date
2. 2nd function --> input paarmter(employee id, startDate, end_date) --> return child node based on selected parent node i.e. start date and end date
I have created two ADF view object based on two function return
Parent Node --> select * from Table( EUPS.FN_GET_CONTR_SAL_BY_YR(employeeId,retirement Date, dateOf joining)) ;
Child Node --> select * FROM TABLE( EUPS.FN_GET_CONTR_SAL_FOR_YEAR( employeId,startDate, endDate) ) based on selected parent node.
I am giving binding variable as input for 2nd function (child node) . I don't know how to reference the binding variable value in child view from parent view.
Like I have to refernce employeId,startDate, endDate values in 2nd function from parent view object. some thing like parentNode.selectedStart_date parentNode.employeeId.
I know we can achive this writing the code in backing bean.But i want to know how can we refernce parent view object attribute values in child view object using Groovy or otherway?
I will appreciate your help.
Thanks

I have two view com.ContractualSalaryByYearlyView for Parent Node and com.ContractualSalaryByYearlyView for child Node.
I have created view link(ContractualSalYearlyByYearViewLink) betweem two view by giving common field empId, stDate , endDate.(below is the view link xml file).
I tried give the binding attribute values using parent object reference like below in com.ContractualSalaryByYearlyView xml file but getting error

No known limitations. Please post the sample DDL to create your object types and object view, along with an example of the example XML document you're trying to insert.

Extending view object which does not have any entity object associated with

Dear all
I am interested in extended on of the standard pages VO object in JDeveloper OA extension
the standard page is oracle/apps/pos/supplier/....suppSummaryPG
and one of the view which I am interested to extend is suppSummVO
the problem is that when I copy xml files and java files from apps server to
my local jdevelope folder , I am not able to open that suppSummVO, the changes which
I find from other VO object and this(suppSummVO) object is that, this VO does not have any
Entity Object associated with it and the only query is return on this VO , is it the reason that
I am not able to open it Jdeveloper, but the real issue is that how can I extends this type of VO
in my OAExtension.
Regard
Noman

Its the same way of extending VO with EO's or without EO's.
Sometimes if the .class files arn't decompiled we get weird jbo errors. So use cavaj/jad to decompile those Impl.class, RowImpl.class files and keep them in the same folder as vo.xml in myprojects and try extending that VO.
Thanks,
Ravi

How to persist an entity with (any) Serializable Java Object as a field?

Hello,
I've understood, that in addition to basic and primary types, an entity bean can have basically any serializable object as its field. I just can't get it working. All I want, is just to have an entity bean with, for example, a HashMap or Properties as one of the its fields. And afterwards, when I'd query the bean again from the persistent storage, it would have the HashMap or Properties fields set just as they were while persisting the bean. So the basic functionality.
So far, the only way I've gotten this working, is by defining the field as byte[] and then by using ObjectInput/OutputStreams and ByteArrayInput/OutputStreams I can read/write my HashMap or Properties as a byte[] and persist the entity... Not very clever, is it :)
I've tried to annotate the field with @Lob but it eventually ends up with casting problems when fetching the data from the persistent storage, because TopLink gets a blob, a byte array from the persistent storage and doesn't know how to convert it into HashMap or Properties like I want it to.
This was close to mine, but still didn't get it working..

ps. Working with AS PE9, MySQL and PostgreSQL..
Best regards,
Samuli

Hello,
Sorry, I'm not sure what you mean. The ID used for the entity does not need to match the actual database constraints, so you can use any mapping in the entity as the ID as long as its value will be unique. If it is not unique, you will run into problems when EclipseLink thinks the entity already exists, performing an update instead of an insert.
Can you describe the performance problems you are having, and what type of sequencing you are using? It is possible to improve performance using batch writing and sequence pre-allocation.
See http://wiki.eclipse.org/Optimizing_the_EclipseLink_Application_(ELUG)#How_to_Use_Batch_Writing_for_Optimization
and http://wiki.eclipse.org/Optimizing_the_EclipseLink_Application_(ELUG)#Table_11-11 for some of the options available.

Type attribute with Object type or Nested table?

Object would have more then one attribute with the tag :VALUE

I'm creating a new component in Ultiboard - a 100 pin connector. This connector (Hirose) has 4 rows of 25 pins. Alternate rows are staggered. I'm trying to name each pin with it's appropiate name: A1, A2, A3 ....A50. Then B1, B2, B3 .....B50.
When I change the VALUE or NUMBER attribute, I get the DRC error message:
This action cannot be completed because the resulting Object would have more then one attribute with the tag :VALUE
Please remove one of the attributes and try again.
Okay, so I've tried deleting the tag and now I can't name the pin at all.
What am I missing?

You should be in the footprint editor to edit the pin name. Select tools>>Database>>Database Manager, highlight the component in your database and click on the Edit icon. In the footprint editor, double click on the pad and a SMT or THT pin Properties dialog appears, select the Attributes tab and highlight the Number row, press the change button and you should be able to change the pin name.

Problem facing with Transient in View Object

Hi Friends,
I had created a new table in the database and create an Entity Object for that table,
i had add this entity object in one of the View Object and when i was trying to add attributes from Available List to the Selected List.
The Attributes are changing to Transient and that particular attribute Mapped to column got unchecked, even tho i check it manually it is turning unchecked automatically when i click on Apply Button.
* In Entity Object Attributes are checked with >Persistent and Queryable and Type is NUMBER Updatable checked to Always.
Can you please suggest me where am i going wrong, i had done me best to solve this problem.
Please help me out from this problem.
Thanks in advance,
Rahul

Setting object attribute in dynamic sql

I am trying to set an object attribute in PL/SQL. It looks like execute immediate is unhappy with
create type test_object as object(username varchar2(200),id number);
declare
obj test_object;
username varchar2(50);
begin
obj := test_object(null,null);
username := 'MIKE';
execute immedaite 'begin :x.username := :y; end;' using obj,username;
end;
Is this supposed to work?

Hi Tony,
Thanks so much for your response. I've had to study up on the dbms_sql package to understand your function... first time I've used it. I've fed my dynamic query to your function and see that it returns a colon delimited list of the column names; however, I think I need a little more schooling on how and where exactly to apply the function to actually set the column names in APEX.
From my test app, here is the code for my dynamic query. I've got it in a "PL/SQL function body returning sql query" region:
DECLARE
v_query      VARCHAR2(4000);
v_as         VARCHAR2(4);
v_range_from NUMBER;
v_range_to   NUMBER;
BEGIN
v_range_from := :P1_FY_FROM;
v_range_to   := :P1_FY_TO;
v_query      := 'SELECT ';
-- build the dynamic column selections by looping through the fiscal year range.
-- v_as is meant to specify the column name as (FY10, FY11, etc.), but it's not working.
FOR i IN v_range_from.. v_range_to LOOP
    v_as    := 'FY' || SUBSTR(i, 3, 4);
    v_query := v_query || 'MAX(DECODE(FY_NB,' || i || ',PFH_HEADCOUNT,0)) '
      || v_as || ',';
END LOOP;
-- add the rest of the query to the dynamic column selection
v_query := rtrim(v_query,',') || ' FROM ('
    || 'SELECT FY_NB, PFH_HEADCOUNT FROM ('
    || 'SELECT FY_ID, FY_NB FROM FISCAL_YEAR) A '
    || 'LEFT OUTER JOIN ('
    || 'SELECT FY_ID, PFH_HEADCOUNT '
    || 'FROM PROJECT_FY_HEADCOUNT '
    || 'JOIN PROJECT_FY USING (PF_ID) '
    || 'WHERE PL_ID = ' || :P1_PROJECT || ') B '
    || 'ON A.FY_ID = B.FY_ID)';
RETURN v_query;
END;I need to invoke GET_QUERY_COLS(v_query) somewhere to get the column names, but I'm not sure where I need to call it and how to actually set the column names after getting the returned colon-delimited list.
Can you (or anyone else) please help me get a little further? Once again, feel free to login to my host account to see it first hand.
Thanks again!

List of objects

All,
in a workflow, we use a multiline container element (LIST) with references to an BOR object type. With a container operation, the values of multiline attribute OBJECTLIST are moved to this container element.
The case is now, that 3x the values are transferred in this 1 operation. So if ISUCONTACT.OBJECTLIST contains 1 object, the element LIST contains 3 objects which are all the same objects.
I have checked if there are other operations or bindings where LIST is used but this is nowhere. Nice case of cinderella effect but this can't be explained... by me that is
Anyone any ideas?
Best regards

Hello,
"With a container operation, the values of multiline attribute OBJECTLIST are moved to this container element."
Is that the usual container operation step?
What happens if you try this in a simple test workflow? Is it easy for someone else to reproduce?

ADF BC Attribute with VC of CONTAINS Ignores Choice List on the LOV

JDev 11g PS 1.
Objects:
- A view criteria with attribute defined as CONTAINS (literal)
- An LOV on that attribute with a default list type UI hint of Choice List
- ADF Faces query-table based in the VC
Problem: query-table ignores the Choice List and renders an Input Text.
Clue: Changing the operator to EQUALS causes the expected Choice List to be rendered in ADF BC.
If this is documented in the online help or in this forum, it is escaping me.
Anyone know the best workaround? Set the VC using EQUALS and switch it to CONTAINS in buildWhereClause() maybe?
Thanks,
Peter

Frank,
Thanks for the fast reply and for the bug entry. Unfortunately stopping work is not an option. We've come up with a solution using a query listener that replaces EQUALS with CONTAINS before the query and resets it to EQUALS after the query (otherwise the component draws the text item after the query).
Maybe you can think of another solution to our requirement: display a single master record in the results table for a master-detail database view. For example, in an altered Oracle HR world, each DEPARTMENTS record is associated with multiple LOCATIONS records (through a DEPT_LOC table). A database view, DEPT_LOC_VW, based on that table also contains the location description and department description.
Users want to select and then edit (on another page) a department by querying by location. If we represent DEPT_LOC_VW in the query-table component, we see multiple result rows for a single department and that is unnecessary confusion for the purpose of editing a single department.
So we have created an alternative database view, DEPT_VW, based on DEPARTMENTS only, with an additional column -- LOC_LIST -- based on a function that returns a delimited list of all location codes for that department. This way, the user sees only one department record in the results table (although we lose the location description in the results -- not an issue) and is still able to query based on location.
A LOCATIONS_VW view contains the location code surrounded with the delimiiter. The DeptVw view attribute LocList contains an LOV based on that database view.
We want the view criteria to create a query condition:
WHERE loc_list LIKE '%'||<selected location code>||'%'We thought about some kind of clever use of a subquery using a bind variable:
SELECT...
FROM departments -- not DEPT_VW or DEPT_LOC_VW
WHERE department_id IN (
   SELECT department_id
   FROM   dept_loc
   WHERE location_id = NVL(:userSelectedLocationId, location_id);But that bind variable does not show in the view criteria selection list so it will not appear in the query component.
Thanks again,
Peter
