ADF Re-Mapping objects from database

Hello
I am developing a web application using ADF, this is my situation: the data base has changed after I maped it to java objects, how can I update the data objects to include those new changes?
Thanks

Hi,
assuming you are using ADF BC you just need to right click on your entity object and select Synchronise with database.
If new attributes (columns) are added you need to edit your VO and add them in.

ADF - Accessing view object from a button in a window

Hi
I am using Jdeveloper 10.1.3.2.0 to build a Swing/ADF application.
I added a method to a view class to call a database procedure.
I use that view as a base of a jTable to display data in a window.
Now I need to call the method that I created in the view class from a button on the same window where I display the data, ideally using the same db connection.
I am quite new to ADF and I have no idea how to get a reference to the view instance in the button method to call my new method. How can I do that? Is there another way to achieve this?
Thanks!
Luis

You usually do this by creating the method at the application module level and then exposing it as a client method. You can then drag and drop it onto your form as a button.
See details in the ADF Developer Guide chapters 8.3-8.5:

Problem with fetching Map object from ObjectInputStream

Hi, please can you help me with the following...I've never seen this before (with my limited experience of JDK1.5)
ObjectInputStream is = new ObjectInputStream(new FileInputStream(store));
Map<Integer, Report> readObject = (Map<Integer, Report>) is.readObject();This code gives me a warning...
Type safety: The cast from Object to Map<Integer,Report> is actually checking against the erased type Map
How can I get rid of this warning?

     ByteArrayOutputStream baos = new ByteArrayOutputStream();
     ObjectOutputStream oos = new ObjectOutputStream( baos );
     List<String> list = new LinkedList<String>();
     list.add( "one" );
     list.add( "two" );
     oos.writeObject( list );
     oos.flush(); oos.close();
     ObjectInputStream ois = new ObjectInputStream
         ( new ByteArrayInputStream( baos.toByteArray() ) );
     List<String> list2 = (List<String>)ois.readObject();Give me 1 compile time error (Test.java:109: warning: [unchecked] unchecked cast), and no runtime errors.
Removing the <String> from "list" add some more [uncheked], but still runs fine (no runtime warning). Adding a none-String only causes a problem when I try to "get" it. (class cast).
When do you get this warning?

Issues in mapping objects from java to flex - using flex4

Hi,
I have a class in java which i want to send to flex4 using BlazeDS as middleware. There are a few issues that i am facing and they are:
When sending the object across (java to flex), the properties with boolean data type having value as true gets converted to properties with value as false. Even after setting the value to true it still comes as false on flex side. Can't understand why this is happening.
When sending the list of object containing property with boolean data type, the object on flex side does not show those properties at all. As of there were no boolean properties in that object.
Last but not the least, When sending List<ContractFilterVO> contractFilterVOs to flex using remote call, the result typecasted to ArrayCollection does not show the holding objects as ContractFilterVOs but as plain default Object though having all the properties send, except the boolean one mentioned in above points. Basically it is not able to typecast the objects in arraycoolection but the same objects gets typecasted when sent individually.
In all the above points i am using Remote Service through BlazeDS for connectivity with Java. I have done a lot of this stuff in Flex 3 but doing it for the first time in flex 4, is there anything that Flex 4 needs specific. Below is the pasted code for reference purpose.
Flex Object
package com.vo
     [RemoteClass(alias="com.vo.ContractFilterVO")]
public class ContractFilterVO{
     public function ContractFilterVO(){
     public var contractCode:String;
     public var contractDescription:String;
     public var isIndexation:Boolean;
     public var isAdditional:Boolean;
* Rmote Part of code
var remoteObject:RemoteObject = new RemoteObject();
remoteObject.destination="testService";
remoteObject.addEventListener(ResultEvent.Result,handleResult);
public function handleResult(event:ResultEvent):void{
     var contarctFilterVOs:ArrayCollection = event.result as ArrayCollection; //Point 2&3 probelem, if list sent form java
     var contarctFilterVO:ContractFilterVO= event.result as ContractFilterVO; //Point 1 probelem, if only single Object of type ContractFilterVO sent form java
Java Object
package com.vo
public class ContractFilterVO implements Serializable
     public function ContractFilterVO(){
     private static final long serialVersionUID = 8067201720546217193L;
     private String contractCode;
     private String contractDescription;
     private Boolean isIndexation;
     private Boolean isAdditional;
I don't understand what is wron in my code on either side, it looks syntactically right. It would be great anyone could help me point out my mistake here. Waiting for right solutions...
Thanks and Regards,
Jigar

Hi Jeffery,
Thanks for your reply, it did solve my query @ point 3 as well as point 2 where the objects in arraycollection were not geting converted and boolean properties did not appear when list of an objects were received. And hey, i did have public functions for properties defined java class, just forgot to mention here in post, sorry for that.
The solution you gave was right, but than what if i have a VO which has multiple List of objects coming from Java, than i would have to create an instance of each type of object on flex side this is too tedious, is'nt it? Is there any better solution... out there.
And jeffery do you some tricks up your sleeve for this Boolean issues to that i am facing in point 1... Still struggling with this one...
Anyone out there would be more than welcome to point my mistake, if any and provide tips/tricks or solutions...
Thanks again to Jeffery...
Waiting for more solutions sooner...
thanks and Regards,
Jigar

JPA2 - downloading large objects from database

Hi,
I would like to enable user to download large (up to 20Mb) files, stored in Oracle database.
I think I should use a stream, but I don't know how to get JPA to return a stream of Large Object. Can you help?
I'm using EclipseLink.

Hello,
http://wiki.eclipse.org/EclipseLink/Examples/JPA/Pagination#Using_a_ScrollableCursor describes using a scrollable cursor to return entities. Since this is going through JPA (you didn't mention what api you are using to access EclipseLink) you will want to be careful to manage/clear your cache appropriately so it does not use all your available memory. You will probably want to make this query read-only, and clear the cache after a few iterations using em.clear().
http://wiki.eclipse.org/Introduction_to_EclipseLink_Queries_(ELUG)#Stream_and_Cursor_Query_Results describes and has links to using streams and cursors with the native EclipseLink read queries.
Best Regards,
Chris

ADF BC View Objects: Disappearing where clauses

Playing around with the 11g Technical Preview I find out that sometimes the where clauses - added to View Objects by means of the new "Join Type" field in the VO-editor UI - disappear.
I'm not able to reproduce exactly and "on demand", but it seems to happen when the sources of more than one View Object are open simultaneously and/or the XML definition of a View Object is edited directly on the Source-tab.

Today I succeeded in reproducing:
Two tables:
TAB_MASTER:
ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL:
ID NUMBER NOT NULL
MASTER_ID NUMBER NOT NULL
DESCRIPTION VARCHAR2 NOT NULL
TAB_DETAIL.MASTER_ID is a foreign key referencing TAB_MASTER.ID.
Steps to reproduce:
1. Generate default ADF BC objects from database tables.
2. Open definition of TAB_DETAIL View Object.
3. Go to the Entity Objects tab
4. Add TAB_MASTER Entity Object to the Selected Entities Objects. Association and Join Type are filled in automatically.
5. Go to the Query tab and go to SQL tab in de Property Inspector. Where clause is filled.
6. Go to the Attributes tab and click Add from Entity...
7. Add TAB_MASTER.DESCRIPTION attribute.
8. Again, go to the Query tab and go to SQL tab in de Property Inspector. Where clause is still filled.
9. Go to the Attributes tab and select MASTER_ID attribute.
10. Click icon to add List Of Values
11. In List Of Values dialog add View Object TAB_MASTER and add the correct pairs of List Return Values for the ID and (MASTER) DESCRIPTION attributes.
12. After completing the List Of Values dialog go to the Query tab -> SQL tab again. The where clause added to join the Entity Objects (see step 5.) is cleared, resulting in a wrong SQL statement for the View Object.

Treat objects from named query as new ones

Hello,
I use TopLink 11.1.1.1.0 and I need to do following. I want to read object from database with named query and let TopLink treat them like new object created in java. Is it possible? Obejcts are in one table but the named query computes them with select from several different tables, so this obejcts are not present in the table.
Why I need it? It is import of data from one module of our application to another. Previously it was done in java. About 500 000 objects were read in one module just to convert into 20 000 objects in another module. If database does this conversion (named query with grouping which reads the 20 000 objects) it is much faster and take much less memory.
What I can do is to create new class with the same fields query this objects and then copy them to object I need. But I don't like creating new class just for this.
Thank for any help
Frank

Thanks for help I solved it different way eventually. I made a stored procedure which inserts data to the table of SOURCE_ITEMS. First I call stored procedure, then I load all new created SOURCE_ITEMS with ReadAllQuery (I have business parameters by which to select them) and make post processing in java with them. I used StoredProcedureCall in TopLink so if exception occurs and transaction rollbacks, stored procedure will rollback as well (I tried it, works for sure:).
StoredProcedureCall call = new StoredProcedureCall();
call.setProcedureName(SQL_IMPORT_CALL);
call.addNamedArgumentValue(SQL_IMPORT_PARAM_1, getId());
call.addNamedArgumentValue(SQL_IMPORT_PARAM_2, getXXX().getId());
call.addNamedArgumentValue(SQL_IMPORT_PARAM_3, getYYY.getId());
call.addNamedArgumentValue(SQL_IMPORT_PARAM_4, getZZZ());
DataModifyQuery query = new DataModifyQuery();
query.setCall(call);
query.setShouldBindAllParameters(true);
// insert of imported SOURCE_ITEMS
ctx.executeQuery(query);
Thanks Chris and hope this will help to somebody else as well..

Map ADF BC Entities to Oracle database object-relational datatypes

Is it possible to base ADF BC Entity objects on oracle DB abstract datatypes or collections?
I see don't see reference to this in the Fusion Dev. Guide for 11g.

Thanks for your reply Steve.
To better understand your use case, what role is the passed-in application module playing, compared with the root application module that any entity object can access already?Somehow I missed that API. I tried this in my example application (see "PolymorphicResourceTaskApp-v0.02.zip":
public class ResourceTaskImpl
     extends EntityImpl
     public void executePreferredAction()
          executePreferredAction(getRootApplicationModule());
     public void executeFallbackAction()
          executeFallbackAction(getRootApplicationModule());
     protected ApplicationModule getRootApplicationModule()
          DBTransaction vDBTransaction = getDBTransaction();
          return vDBTransaction.getRootApplicationModule();
}This allows me to implement my "actions" (methods) without passing in an Application Module instance.
Or would you suggest a different way to get the root Application Module in an Entity Object implementation?

JSF/ADF/Toplink object from multiple schemas

We are considering starting a new project using JSF/ADF/Toplink using a already existent database.
How is it possible to create toplink object from tables when tables belongs to different schemas?
I think there must be a way to do this and in jdeveloper forum suggested me to post the question here.
Thank you very much.
Michele

Michele,
When you are in the wizard where it lets you select the tables you can select one schema and query and select your tables. Then you can switch schemas and query and select additional tables.
When using TopLink this way you will most likely need the SQL generated qith schema qualified tables. To do this go to the map (under TopLink node) and edit its defaults tab and check the option 'Qualify Table Names with Schema Name".

Mapping Objects to Relational Databases

Hi,
I do not know if this is the more suitable forum to ask this question, but I am going to try it:
I am developing an application with two parts.
1. A server developed in J2SE which is connected to a MySQL database.
2. A client developed in Swing which shows data received from the server by RMI.
Up to now, I map the relational database data in objects manually in the server side. But I would like to use a framework to do this (JDO, EJB 3.0, hibernate...).
I have read a lot about them, but I have serious doubts. Can I use them with J2SE? I think that it is necessary to use JBoss (or another application server) if I use EJB, it is true? Which is the easiest?
Which technology do you advice me?
I am very confused, thanks in advance.

I am developing an application with two parts.
1. A server developed in J2SE which is connected to
a MySQL database.Interesting since the JDBC API is not part of J2SE. How do you connect to the database without using JDBC? If you are using JDBC, why are you so confused?
2. A client developed in Swing which shows data
received from the server by RMI.Again, the RMI API is not part of the J2SE. If you are truthfully writing RMI code, which is complex, and you are writing Swing code, and you may be writing JDBC code, why are you very confused?
I have read a lot about them, but I have serious
doubts. Can I use them with J2SE? Did read a lot about them? Why do you have serious doubts? Did you understand what you read?
I suggest you read some more.

Hey Ayaz,
I do had the same error message when I click on "PowerPivot Management Dashboard". After few research I resolved this issue.
You need to provide the dbReader and dbWriter permission to powerpivot app pool account at "SharePoint_AdminContent_ca021d58-ef1f-4f30-9aeb-6f24db24862b"
Have a great day :-)

ADF delete from database.

Hi,
I am trying to design a page which will delete a particular row from one or more database tables. The jdeveloper version is 11.5 and the database is oracle 10.2 version.
How can I do it?
Thanks

Hi all, Thanks for the reply..
Actually I am trying to delete one record at a time, from the same table, from which m populating it on the jspx..
That means the list source and the base source are same..which is not possible..
What can be the solution for it ??
I tried to create a separate view object for population on jspx and kept it in list source.. And I am using different view object in base source.. Both view objects refer to the same table..
But it is not working out..the problems are..
The record is getting deleted only for the first time when i run it.. Even after getting deleted from database, the record shows up in the list..
And when i do the same operation one more time in the same session, 1st record in the table is getting updated with the value which i tried to delete..
And I am not using managed bean..
regards
