Creating and Binding View Objects dynamically : Oracle Jdeveloper 11g

Hello,
We are trying to create and bind view objects dynamically to adf data visualization components.
The view object is a result of multiple tables.
We are using Oracle JDeveloper 11g Technical Preview. ( can't upgrade to TP2 or TP3 now).
We have found this : http://radio.weblogs.com/0118231/stories/2003/07/15/creatingUpdateableMultientityViewObjectDefinitionsDynamically.html on our search for the same.
The sample application however, is in 10g , hence required migration.
Also, it was a standalone application with the TestClient.java having a main() method.
Our requirement is for Web Application; we use Adf+jsf .
Guidance of any sort is very much appreciated.
Thanks in advance.

Hi,
there also exist a forum for JDeveloper 11: JDeveloper and OC4J 11g Technology Preview
What you are trying todo is not trivial because you need to not only dynamically create the VO, you would also dynamically need to create the binding meta data for it (assuming you use ADF). Not sure if the API to modify the binding is public, so posting it on the JDeveloper 11 forum bears a glimpse of hope for an answer
In JDeveloper 10.1.3 you can't do this

A dynamic table based on run-time created view object -- please help!

Hello!
I'm trying to create a dynamic table based on an run-time created view object. All go ok, but table binding component take the first view/iterator state and don't reflect changes they have. Please, take a look:
1. At run-time the view is being replaced by new red-only one based on query in application module:
getQueryView().remove();
createViewObjectFromQueryStmt("QueryView", statement);
2. Page definition file contains an iterator (using iterator or methodIterator - doesn't matter) binding and table, which binds to the iterator, like:
<methodIterator id="distributeQuery1Iter" Binds="distributeQuery1.result"
DataControl="QueryServiceDataControl" RangeSize="10"/>
<table id="distributeQuery11" IterBinding="distributeQuery1Iter"/>
3. The page code uses <af:table>. But, if I use table binding (it's right) like this:
<af:table var="row" value="#{bindings.distributeQuery11.collectionModel}">
<af:forEach items="#{bindings.distributeQuery11.attributeDefs}" var="def">
the table will never changed (i.e. still show the first view instance).
When I tried to use iterator binding directly (it's bad and cannot provide all needed features unlike CollectionModel from table binding) I saw that table works!
(Code is somehing like:
<af:table var="row" value="#{bindings.myIterator.allRowsInRange}">
<af:forEach items="#{bindings.myIterator.attributeDefs}" var="def">
Why the table binding do not reflect changes in iterator? Or should I use different approach?
Thanks in advance!
Ilya.

I got it to work! I used a hybrid approach comprised of some of your code and some of Steve Muench's AcceessAppModuleInBackingBean example.
In the setBindings method, I execute an app module method that redefines the query, then I used your code to delete and recreate bindings and iterator:
public void setBindingContainer(DCBindingContainer bc) {
this.bindingContainer = bc;
rebuildVO();
The rebuildVO() method looks like the code you provided in your example:
private void rebuildVO() {
DCDataControl dc;
DispatchAppModule dApp;
DCBindingContainer bc;
DCIteratorBinding it;
OperationBinding operationBinding;
ViewObject vo;
DCControlBinding cb;
try {
bc = getBindingContainer();
dc = bc.findDataControl(DATACONTROL);
dApp = (DispatchAppModule)dc.getDataProvider();
// Execute App Module Method to rebuild VO based upon new SQL Statement.
dApp.setDispatchViewSQL();
vo = dApp.findViewObject(DYNAMIC_VIEW_NAME);
it = bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME);
it.bindRowSetIterator(vo, true);
// logger.info("Remove value binding...");
cb = bc.findCtrlBinding(DYNAMIC_VIEW_NAME);
cb.getDCIteratorBinding().removeValueBinding(cb);
bc.removeControlBinding(cb);
// logger.info("Creating new value binding...");
FacesCtrlRangeBinding dynamicRangeBinding =
new FacesCtrlRangeBinding(null,
bc.findIteratorBinding(DYNAMIC_VO_ITER_NAME), null);
// logger.info("Add control binding...");
bc.addControlBinding(DYNAMIC_VIEW_NAME, dynamicRangeBinding);
} catch (Exception e) {
e.printStackTrace();
And my App Module method that redefines the view object looks like this:
public void setDispatchViewSQL() {
String SQL =
"begin ? := PK_BUsiNESS.F_GETDISPATCHVIEWSQL();end;";
CallableStatement st = null;
String ViewSQL = null;
try {
st = getDBTransaction().createCallableStatement(SQL,
DBTransaction.DEFAULT);
* Register the first bind parameter as our return value of type LONGVARCHAR
st.registerOutParameter(1, OracleTypes.LONGVARCHAR);
st.execute();
ViewSQL = ((OracleCallableStatement) st).getString(1);
findViewObject(DYNAMIC_VO_NAME).remove();
ViewObject vo = createViewObjectFromQueryStmt(DYNAMIC_VO_NAME, ViewSQL);
vo.executeQuery();
} catch (SQLException s) {
throw new JboException(s);
} finally {
try {
st.close();
} catch (SQLException s) {
s.printStackTrace();
When I run it I get my desired results. One thing I don't quite understand is why when the page is first rendered it shows the last set of records rather than the first. Now I have to figure out how to put navigation URLS in each of the table cells.
Thanks for your help; I would not have gotten this far without it,

Create View Object programattically from XML input

Hi,
I have requirement to create view object from xml at run time in ADF application. is there any way to create view object dynamically in java program from xml?
My requirement is to call a webservice and generate view object from the response of the web service call.
Thanks

I want to create view objects from different web services and the same will be available to the developer at the time of development. I don't want to create web service proxies for each of the web service. this will simplify the developers task to create proxy and data controls. the one thing developer has to do is select the service and base on the service the view objects will be created to develop pages accordingly.

Create view object from

How to do it?
Thanks!

Check out the createViewObjectFromQueryStmt() method of the Application Module.
See:

Creating View Objects at Runtime for Validation

In Oracle® Application Development Framework
Developer’s Guide For Forms/4GL Developers tutorial there is a topic about Creating View Objects at Runtime for Validation.
Is there any sample code available for this topic?
Please help
Regards
S Karar

I have created a helper method . The code is given below
protected ViewObject getValidationVO(String viewObjectDefName) {
// Create a new name for the VO instance being used for validation
String name = "Validation_" + viewObjectDefName.replace('.', '_');
// Try to see if an instance of this name already exists
ViewObject vo = getDBTransaction().getRootApplicationModule().findViewObject(name);
// If it doesn't already exist, create it using the definition name
if (vo == null) {
vo = getDBTransaction().getRootApplicationModule().createViewObject(name,viewObjectDefName);
return vo;
// Validation_bc4j_project of type ApplicationModule not found
and created a validation method.
The code inside validation method is given below.
public boolean validateAvgMr(Number data) {
String batch_catg = getQuality();
// Get the view object instance for validation
ViewObject vo = getValidationVO("bc4j_project.v_sqc0150");
if (getTestStage()=="DOLLOP" && getQuality()=="DECO")
// Set it's bind variables (which it will typically have!)
vo.setNamedWhereClauseParam("batch_catg","DECO");
vo.executeQuery();
Number dol_mr_lcl=(Number)vo.first().getAttribute("DolMrLclStd");
setStdMrLcl(dol_mr_lcl);
return true;
return true;
I have checked the validation view and it is returing value with the same bind variable value but is not returning any value when using inside this method validation.
I have checked several times but can't find the fault in the code.
Please help

What is the diffrence between extends and creating new object?

HI ALL,
what is the diffrence between extends and creating new object?
meaning
class base{
class derived extends base{
class base{
class derived {
derived(){
base var = new base();
can u people tell me diffence from the above examples.
THANKS.
ANANDA

When you create a new object you have to supply the class to which that
object belongs. A class can extend from another class. If it does so
explicitly you can define the 'parent' class from which the class extends.
If you don't explicitly mention anything, the class will implicitly extend
from the absolute base class named 'Object'.
Your example is a bit convoluted: when you create a Derived object,
its constructor creates another object, i.e. an object from the class from
which the Derived class extends.
Extending from a class and creating an object don't have much in common.
kind regards,
Jos

Package and class viewer

Hello,
Is there an equivalent of a menu item or short-cut key to bring up package and class viewer? A similar feature exists in Eclipse which builds the indexes and Ctrl-Shift-T will bring up all the classes in your workspace / project. I have seen something similar in Jdeveloper while running in debug mode, if it cannot find a file that is need for trace options, it throws up a window that says "Package and Class Viewer". It would be useful to access that during development as well.
Thanks
Farooq.

Thanks for the repose. Ctrl+ , along with Ctrl= is doing the same thing. Also discovered Ctrl- will bring up java classes. Only thing remains is the remaining files in the project e.g XML or JSP files
Thanks for you, got me in the right direction.

If you want to import an entity object, then click on the add component to project button in the JDeveloper Navigator pane. From the list of files, select the xml file for the desired entity object. the xml file and the corresponding java files will be added to ur project.

I don't know exactly which one we have to use

Hi,
Set the log level to 2 and the queries generated by the obiee and sql will be same.

Creating and Using View Objects on JDev 10g against SQL Server 2005

I'm currently working on this project on Jdeveloper against a SQL Server 2005 DB (I couldn't talk this people to migrate to Oracle... :-( ), and it's the first time I work with JDev against a database other than 10g.
I had no problem making the connection, and I can see the DB in Conections->Databases, but when I create an app. module, and create entities and views and add them to the app. module to access them through the Data Controls, these don't work. I can see the view on the Data Controls, and when I drag them to my jspx page it shows the menu that let's me choose whether I want to create a table, or a selection, or a tree, but once I choose one, it does nothing.
I've search all over the internet and haven't found a solution, so I come to this forum desperate for help, seriously.
Please get in touch; if anyone knows another solution that doesn't involve not using JDev or SQL Server 2005, please let me know, because I basically need to have a few selectonechoice showing some data from a few tables.
Thanks for reading this post, and hope to get help.
Carlos.

Hi,
can you run the model in the ADF BC tester ? If this is possible the SQL Server doesn't seem to be the problem. Are you on JDeveloper 10.1.3.3? If not, just get this latest build

How to create View Object with Multiple Updatable Entity Objects

http://docs.oracle.com/cd/E21043_01/web.1111/b31974/bcadvvo.htm#CEGCAJCI which overrides the exiting classes. but i would like to do it declarative . Is there any other way to do it?
I am using Jdeveloper 11g version 2.
Thanks in advance,

View link creation on two view objects, and both view objects are populated program(not from sql)

I have master and detail VO , both views data is loaded in program. Now for show/hide feature, I create View Link Object and using one element from both child and master VO , View Link Object created properly.
But I can not able to add that view link object into AM.
Now because of that , I cannot say what is a instance name of that view link object.
Hence getting following error -- Invalid or missing view link. Please attach view link with the bean.
Please can you provide some directions.

How to create view object for a predefined Oracle view

Trying to create an entity object with no success,,,
I have an Oracle view(complex query in PL/SQL) that I need to encapsulate as a View Object then represent a column from this view as a '' | | linkcolumn | | ''
then get a reference of the requestParameter "p" in this case that I need to use as whereclause parameter on another view object that is part of the ListPage.jsp.
The application is basically a page of organization links that when click filters their reports as a list,
In Jdeveloper's context webBean(RowSetBrowser list [org links] to RowSetBrowser [org report list])
Can I implement this functionallity using the wizards or possibly writing custom code using the standard webBeans.

Jerry,
First, you can create an entity object based on an Oracle view. If you check the "Views" checkbox in the EO wizard, you'll see a list of database views. Then you can create a view object based on your entity object, and use it like any other view object.
As for getting the page into the format you want, I suggest you start by generating your page using the BC4J JSP wizard, then customize the generated JSP.
Thanks
Blaise
