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

Error when dynamically creating and binding view object

Hi,
I'm using JDeveloper 10.1.2.1.0 (1913) to create a JSP - Struts - ADF BC application.
I'm trying to create a lov page that is based on a viewobject whose query (and bindings) are set at runtime (like Steve Muench shows in one of his undocumented ADF samples).
In the prepareModel() I do the following:
-unbindRowsetIteratorFromDynamicQueryIteratorBinding(...)
-changeDynamicViewObjectQuery(...)
-recreateRangeBindingForDynamicQuery(...)
-removeControlBinding(...)
-addDynamicRangeBinding(...)
So I remove the existing binding, change the query of the viewobejct and recreate the bindings.
I have got most of the code running except for 1 issue:
1. The first time I call my Lov I get the a stacktrace (included at the end of this post). If I close the window and click the Lov button again it is working fine.
Can someone help me out with this one???
Here is the stacktrace I am getting:
javax.servlet.jsp.JspException: An error occurred while evaluating custom action attribute "value" with value "${bindings.OpmerkingenLookupIterator.rangeStart}": An error occurred while getting property "rangeStart" from an instance of class oracle.jbo.uicli.binding.JUIteratorBinding (java.lang.NullPointerException)

Here is some more info:
I can reproduce the problem using the code Steve Muench supplies in his undocumented ADF samples.
If you add the following line to the jsp in the example code(browseResultsOfDynamicVO.jsp):
<c:set var="rangeStart" scope="request" value="${bindings.DynamicViewObjectIterator.rangeStart}"/>You will get the behaviour I am facing.
The first time in your session you enter a valid query and submit it you get a stacktrace. By refreshing the page it works.
It looks like that when recreating the bindings at runtime something more is fone that isn't done at design time. So the first time the statement fails but once the bindings have been recreated at runtime it suddenly works....
The main question is: what is it that is done at runtime and is missing at design time?

Create and bind javafx objects out of java

hello,
iam start to learn javafx and cant find the right way to do what i want.
the goal is: i have written a graph datastructure in java and want to parse a xml file. for every String in the xml file a new node in the graph should be created. this node holds the data and a position (2D). now evertime a node in the graph was created, a visual representation for this node should pop out in my javafx stage. when the position of the node changed the visual rep. should notice this or rather a function on this object is called (observer).
is javafx an approach to do so? or should i use java2d?
do you know a tutorial where i can learn how to create an call javafx objects out of java and how to put them into the stage/scene?
i found this: http://java.sun.com/developer/technicalArticles/scripting/javafx/javafx_and_java/index.html
but there is not mentioned how to put the object into the stage/scene.
regards
peter

thanks. this is also a good article. [http://blogs.sun.com/michaelheinrichs/entry/binding_java_objects_in_javafx|http://blogs.sun.com/michaelheinrichs/entry/binding_java_objects_in_javafx]

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

Using different datasources and different view objects.. (ADF 11g)

In our application we have the need for using two different datasource (an old version and a new verision) - but not at the same time.
Isn't it possible to base a viewobject on top of two sub viewobjects and run time decide which sub viewobject to use?
If possible - could someone please show some code examples?
Thanks...

Hi,
no, not exactly. You can have polymorphic views, but the use case is a different. The transaction is maintained by the AM, so if you want to connect to different data sources then you have to connect to them when starting the application, For this you can configure it for dynamic JDBC connect

DISTINCT in SELECT statements for Entities / Views - Oracle JDeveloper 11G

Hi Steve,
i have a question about using DISTINCT in SELECT statements for
Entities / Views. On Oracle JDeveloper 11G ADF / BC4J
--- This is unique---
SELECT
distinct(GC."course_title"),
GC.SEC_GRP_PARENT_ID,
from "grp_courses" GC
--- This is NOT unique, but ROWID seems to be mandatory as PrimaryKey---
SELECT
distinct(GC."course_title"),
GC.SEC_GRP_PARENT_ID,
rowid
from "grp_courses" GC
How to use this query;
SELECT
distinct(GC."course_title"),
GC.SEC_GRP_PARENT_ID,
from "grp_courses" GC
and yet still be able to use it in View / Entity without a Primary Key or some equivalent solution.
Thanks & Regards,

Hi, OK - I got it to work...
Some notes:
1) The View wizard cannot be initiated from the Entity Object.
2) During the View wizard process - do not associate with Entity
3) Selected columns must be mapped as expressions
4) Using non-distinct columns will override the distinct function

How to Create and Deploy Web Services Using Oracle 9i JDeveloper

Hi,
My Question is how to create and deploy Web Services using Oracle 9i JDeveloper.Anybody please give me a detailed Reply.Please Reply to [email protected]
Hopr to Hear From you,
Regards,
G Sreekumar

You could use datasources. You should do this in your BC4J Configuration. Then when deploying your applicaiton use the command -installDataSource (from admin.jar) to create the right datasource.
You could probably use the name of your connection + "DS" so you can also use it locally in JDeveloper as JDev seesm to create this automaticly for your Connections.

Desktop app - creating and destroying forms/frames dynamically.

Hi all,
I'm creating a small crypto app for the desktop using java.
I'm using JFrames (import javax.swing.JFrame) with Oracle JDeveloper 11g under Linux.
I want to have a "welcome" form/frame where users can choose their encryption method,
and then on choosing the method, I want to dynamically create the appropriate form for
the chosen encryption method and also destroy/free/dispose() of the welcome form.
When the user has finished their encrypting, they should close the frame/form (either by
clicking on the x at the top right - or using the Exit button or by any method) and the
welcome frame should be dynamically recreated and appear.
I've tried various things - btnEncode_actionPerformed(ActionEvent e) then
this.dispose() - and I've fiddled with this_windowClosed(WindowEvent e) and
dispose(), but nothing seems to work.
Even a workaround using setVisibl(true/false) would be acceptable at
this stage - this has been wrecking my head all day. It's very easy to do in Delphi!
TIA and rgs,
Paul...

What do you mean that "nothing seems to work"? What does it do instead?
Post a small piece of runnable code that demonstrates the problem, and we'll go from there.

Possible bug when creating multiple detail view objects

using jdev 11.1.1.0.0 to build jsf/adf applications. I wanted to report what seems like a bug in 11g. I have a parent table which has two child tables. After creating the appropriate entities, associations, views, and view links, the app module looks like this:
MasterView
--DetailView1
--DetailView2
The two detail view objects are on the same level, they are both direct children of the Master view.
Here's what's happening:
1) I create the master entity/view objects (MasterView)
2) I create one of the detail entity/view objects (DetailView1).
3) I create the association and view link to establish relationship between MasterView and DetailView1. Everything works fine.
4) I create the entity/view objects for second detail view (DetailView2)
5) When I attempt to create a second view link (based off an association) to establish the relationship between MasterView and DetailView2, the query clauses of the Create View Link wizard (screens 4 and 5) do not get created properly. I finish the wizard and save. Not only does this view link not get created properly, but in the process the query clauses that were defined in the first view link between MasterView and DetailView1 are wiped out. This will break any coordination between master and detail views in both the app module tester and runtime. Has anyone seen this problem?

fyi, it looks like this issue has been resolved with jdev 11.1.1.0.2 (Update 2)

Hi,
you can start the Jdev by command line and then see the log that it is generating. Maybe there you can see the problem that is happening.
Also you can check if the server is running with
     telnet hostname 7001
Some possible reasons
     you have a firewall blocking the connection
     did you check /etc/hosts file entry ? should be something like this <ip address of host > hostname1

OMBPLUS "Create and Bind" command

Hi All,
I'm looking for a command or the ombplus syntax to have the same functionality as a 'Create and Bind' in the OWB gui. Does something like that exist?
More specifically: at the moment we have a script creating mappings from (imported) source tables generating flat files. The latter are created as a mapping object and we would like to avoid having to create them again and bind it manually, instead of just executing the 'create and bind' function.
We are using OWB 11.1.0.7 at the moment.
Thanks,
Michel

Hi Michel
You can use the OMBRECONCILE command to do this. The data mover expert on the exchange does something like it (here).
OMBRECONCILE MAPPING 'MAP' OPERATOR 'FF' TO FLAT_FILE 'PROJECT/MODULE/OBJ' USE (RECONCILE_STRATEGY 'REPLACE', MATCHING_STRATEGY 'MATCH_BY_OBJECT_NAME')

How do I do to add and remove Shape3D objects dynamically from TransfGroup?

Hi, everyone,
How do I do to add and remove Shape3D objects dynamically from TransformGroup?
I have added two Shape3D objects in the TransformGroup and I wanted to remove one of it to add another. But, the following exception occurs when I try to use �removeChild� :
�Exception in thread "AWT-EventQueue-0" javax.media.j3d.RestrictedAccessException: Group: only a BranchGroup node may be removed at javax.media.j3d.Group.removeChild(Group.java:345)�.
Why can I add Shape3D objects and I can�t remove them? Do I need to add Shape3D object in the BranchGroup and work only with the BranchGroup? If I do, I think this isn�t a good solution for the scene graph, because for each Shape3D object I will always have to use an associated BranchGroup.
Below, following the code:
// The constructor �
Shape3D shapeA = new Shape3D(geometry, appearance);
shapeA.setCapability(Shape3D.ALLOW_GEOMETRY_READ);
shapeA.setCapability(Shape3D.ALLOW_GEOMETRY_WRITE);
shapeA.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
shapeA.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
Shape3D shapeB = new Shape3D(geometry, appearance);
shapeB.setCapability(Shape3D.ALLOW_GEOMETRY_READ);
shapeB.setCapability(Shape3D.ALLOW_GEOMETRY_WRITE);
shapeB.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
shapeB.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
BranchGroup bg = new BranchGroup();
bg.setCapability(ALLOW_CHILDREN_READ);
bg.setCapability(ALLOW_CHILDREN_WRITE);
bg.setCapability(ALLOW_CHILDREN_EXTEND);
TransformGroup tg = new TransformGroup();
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_WRITE);
tg.setCapability(TransformGroup.ALLOW_TRANSFORM_READ);
tg.setCapability(TransformGroup.ALLOW_CHILDREN_READ);
tg.setCapability(TransformGroup.ALLOW_CHILDREN_WRITE);
bg.addChild(tg);
tg.addChild(shapeA);
tg.addChild(shapeB);
// The method that removes the shapeB and adds a new shapeC �
Shape3D shapeC = new Shape3D(geometry, appearance);
shapeC.setCapability(Shape3D.ALLOW_GEOMETRY_READ);
shapeC.setCapability(Shape3D.ALLOW_GEOMETRY_WRITE);
shapeC.setCapability(Shape3D.ALLOW_APPEARANCE_READ);
shapeC.setCapability(Shape3D.ALLOW_APPEARANCE_WRITE);
tg.removeChild(shapeB);
tg.addChild(shapeC);Thanks a lot.
aads

�Exception in thread "AWT-EventQueue-0"
javax.media.j3d.RestrictedAccessException: Group:
only a BranchGroup node may be removed I would think that this would give you your answer -
Put a branch group between the transform and the shape. Then it can be removed.
Another thing you could try: This doesn't actually remove the shape, but at least causes it to hide. If you set the capabilities, I think you can write the appearance of the shapes. So, when you want to remove one of them, write an invisible appearance to it.

HI,
check the jdbc url.
The datbase and the listener to which you are connecting are suppose to be up and running.
For testing try and connect using sqlplus from the machine you are trying to make a connection,

When I use Oracle Jdeveloper 10g (10.1.3.4.0) , I can use it to set Libraris.
I have a swing application need these operation.
Does anyone can tell me what's the reason?
Thanks.
I had tried Oracle JDeveloper 11g R1 (11.1.1.1.0)(Build 5407).
It is OK.
Maybe I need to download Oracle JDeveloper 11g (11.1.1.2.0) again.

I am encountering the same bug / problem right now.
Anybody from Oracle who has a workaround for this BUG?
We are migrating to JDev 11.1.1.2.0 for a client and this bug is still there!
Any help from the JDev team is highly appreciated!
