Entity object track changes "Modified by"

Hi Experts,
I have a question about entity object track changes. I change enabled one entity object attribute to track change "Modified by".
However whenever the DB changes occurs then the Modified column is updated, however the name is the database connection user name. How can i override that value during the record update. Do i need to set any DbTransaction.session environment variable to save that in the db/
- t

Sorry for the late reply,
I tried this but no luck. Can anyone let me know how to change the entity history columns values like modified by user name. etc....

Dynamic Creation of Entity Objects (ADF Business Components)

Hi All,
We have a requirement to create Entity Objects for the dynamically generated tables in our application and at the same time bind them to different views.
Our product create multiple tables at runtime with some sort of naming convention, and we couldn't find a way in JDeveloper to generate entity objects for the tables created dynamically.
Please provide some pointers if you have experienced or worked on similar requirement.
Thanks,
Nikhilesh

Thanks for the help Sudipto.
The link which you have shared, describes the creation of an entity object and then modify the operations like Delete Update and Insert etc to be performed on the entity object by creating IMPL classes and implementing certain interfaces.
But I need to create Entity objects dynamically. My application creates new tables for some functionality at the run time and I have to create Entity objects for those new tables as soon as the new tables are created.
I was just wondering if, there is any API available for creating the entity object from Java code instead of invoking the wizard in the Jdeveloper.

How to change 'Modified By' column value when a new file is uploaded in SharePoint 2013 using Client Object Model?

I want to change 'Modified By' column value of a file that is being uploaded using Client Object Model in SharePoint 2013. The problem is that the version of the file is changing. Kindly help me. The code that I am using is:
using (System.IO.Stream fileStream = System.IO.File.OpenRead(m_strFilePath))
Microsoft.SharePoint.Client.File.SaveBinaryDirect(m_clientContext, str_URLOfFile, fileStream, true);
Microsoft.SharePoint.Client.File fileUploaded = m_List.RootFolder.Files.GetByUrl(str_URLOfFile);
m_clientContext.Load(fileUploaded);
m_clientContext.ExecuteQuery();
User user1 = m_Web.EnsureUser("User1");
User user2 = m_Web.EnsureUser("User2");
ListItem item = fileUploaded.ListItemAllFields;
fileUploaded.CheckOut();
item["UserDefinedColumn"] = "UserDefinedValue1";
item["Title"] = "UserDefinedValue2";
item["Editor"] = user1;
item["Author"] = user2;
item.Update();
fileUploaded.CheckIn(string.Empty, CheckinType.OverwriteCheckIn);
m_clientContext.ExecuteQuery();

Hi talib2608,
Chris is correct for this issue, when calling update using ListItem.update method, it will increase item versions, using SystemUpdate and UpdateOverwriteVersion will update the list item overwrite version.
these two methods are not available in CSOM/REST, only server object model is available for this.
Thanks,

How to track changes in DataTable rows?

Hi,
I'm wondering what are you using to track changes in datatables. As far as I can tell, there is no way to know what editable componentes in each row have been modified. That forces you to clone() the objects in the rows to compare them after the user submits the form.
This works without problems, but somewhat I feel it's dirty. What approach are you using ?
Best regards,
- Juan

I have not tried that. But you could wire a value change listner to track what is changing. Or do do what you are doing now. Or wait for SDO (service data object) to become part of J2EE specs (coming soon)

How to Insert the System Date in the entity object

Hello,
I have the problem - in entity object I have one attribute as 'Created_Date' in the <entity>Impl.java,
to this attribute I want to assign the value as a System Date. Could someone please let me know how to do this?
Thanks

Hint for all who are trying another solution. You might think it's easier to assign a SystemDate using this method:row.setDate(new Timestamp(System.currentTimeMillis())); But unfortunately this solution has a real gotcha! Doing this you are writing an Attribute with a precision of milliseconds. Unfortunately the SQL-Date type can hold only full seconds. So this solution sometimes leads to the Problem that BC4J complains that "someon else has changed the row" (in reality the database has simply stripped off the seconds).
Even if you are trying to convert the Timestamp to an oracle.jbo.domain.Date like this Date myDate = new Timestamp(System.currentTimeMillis()));
row.setDate(myDate); you will not be able to solve the problem. 'myDate' still holds the milliseconds, it only doesn't display them. You might still discover that BC4J complains for modified rows.
So the solution given by Faraz is definitively the best solution, even if it looks complicated, as it strips off the milliseconds.

HELP URGENT - Entity Object Substitution not working as advertised!!!!!

Hi All,
I have done an entity Object substitution and in order to rule out any coding errors on my part I have generated a fresh EO with no code changes in it and uploaded the files to java top and updated the MDS with the substitution.
The substitution is successful but I get the following error related to my substituted file:
oracle.apps.fnd.framework.OAException: oracle.jbo.AttrValException: JBO-27019: Get method for attribute "ItemNumber" in XxEgoMtlSystemItemsVLEOEx could not be resolved. at oracle.apps.fnd.framework.OAException.wrapperException(OAException.java:912) at oracle.apps.fnd.framework.webui.OAPageErrorHandler.prepareException(OAPageErrorHandler.java:1169) at oracle.apps.fnd.framework.webui.OAPageBean.renderDocument(OAPageBean.java:3241) at oracle.apps.fnd.framework.webui.OAPageBean.renderDocument(OAPageBean.java:3036)

I think the real error is Detail 0 line but I haven't seen this before. Could this be the wrong version of JDeveloper that I have used????? About this page showed 12.1.2 and I have downloaded the JDev for 12.1.2???????
Please help I need to sort this ASAP.
Thanks all

I have covered everything in the above threads and followed the EO substitution scenario exactly as per area51.
I am now getting a different error on the EO substitution, when the page loads that creates a row in the EO the following error is displayed:
Error
1. Attribute set for InventoryItemId in view object EgoMtlSystemItemsVO failed
2. Attribute set for InventoryItemId in view object EgoMtlSystemItemsVO failed
3. Attribute set for InventoryItemId in view object EgoMtlSystemItemsVO failed
4. Attribute set for InventoryItemId in view object EgoMtlSystemItemsVO failed
This is a caught error and thrown to the top of the page as opposed to a complete stack error which is what I was getting before? At first I thought this was due to the VO substitution I had done earlier as a test but I have deleted the substitution document for the VO sub and if I remove my EO substitution the page works fine so my EO substitution is causing the problem.
EO substitution was as follows:
<Substitutes>
<Substitute OldName ="oracle.apps.ego.item.eu.server.EgoMtlSystemItemsVLEO" NewName ="xxsdg.oracle.apps.ego.item.eu.server.XxEgoMtlSystemItemsVLEOEx" />

26.4 Basing an entity Object on a PL/SQL Package API - Ref Cursor, no View

I am hoping that I could get some help in the details of a problem. I am trying to follow the directions in the Oracle Application Development Framework Developer's Guide for Forms/4GL Developers, Section 26.4 - Basing an Entity Object on a PL/SQL Package API.
There is example code in the downloadable AdvancedEntityExamples - EntityWrappingPL/SQLPackage
The question is, how will the implementation change if the entity is based entirely on PL/SQL - simply stated - no view is available, just ref cursors and insert,update,delete procedures.
In the example code, there are two procedures, lock_product and select_product. This is where things get more complicated. I can create a function to return a single record ref cursor, instead of the list of OUT variables defined in both functions (select_product and lock_product). It makes sense that I just return one cursor and get all of the columns from that instead of lots of OUT variables.
So what's stopping me you may ask... There is one difference between select_product and select_lock. Select_lock has a select that includes "FOR UPDATE NOWAIT". I don't have that as an option when creating my ref cursor. I am not sure what the impact of "FOR UPDATE NOWAIT" is? Can I ignore it?
In the problem I am working with, (getting data from Oracle Portal 10.1.4) I return the following:
function getRefCursor return ref_cursor is
v_tab wwsbr_all_items_object_type := wwsbr_all_items_object_type();
p_recordset wwsbr_types.cursor_type;
l_results wwsrc_api.items_result_array_type;
begin
wwctx_api.set_context(<username>,<password>);
l_results := wwsrc_api.item_search(.. parameters..);
<snip>
... Loop through the objects and populate v_tab
<snip>
open p_recordset for
select * from table(cast(v_tab as wwsbr_all_items_object_type));
return p_recordset;
end getRefCursor;
With this sample, it would be easy to return a single row by passing the masterid as a parameter.
So I am still left with, how should the implementation of callLockProcedureAndCheckForRowInconsistency() and callSelectProcedure() be changed in order to use a ref cursor instead of a view? The user guide was missing that extra section <bg>.
What would be REALLY helpful, is an example, say 26.4A that demonstrates creating an entity object from a ref cursor and procedures from PL/SQL only without a view.
Thank you, Ken

The lock procedure is expected to obtain a row-level lock on the row, given its key.
Depending on the setting of jbo.locking.mode, the entity object's lock() method will be invoked either as soon as the first persistent attribute is successfully modified by the user (in the case of jbo.locking.mode=pessimistic), or it will be called during commit processing just before the row is updated in the database (with jbo.locking.mode=optimistic).
Usually 2-tier Swing applications use pessimistic mode, while web applications use optimistic mode.
The FOR UPDATE NOWAIT is the Oracle clause that can be appened to a SELECT statement to acquire a row-level lock on the selected rows. The NOWAIT modifier means that rather than hanging, waiting for a row locked by another user to free up, it will raise an exception if any of the rows being selected-and-locked are not available to lock.
If you're not able to work the FOR UPDATE NOWAIT into the syntax of the ref cursor, perhaps you can initially perform the lock using a different cursor inside the stored procedure, then return your ref cursor.

Track changes on 'Z' tables

Hi,
We have a requirement that to track changes on our Z tables. Could any one help me in process of doing this ?
Thank you,
Surya

HI,
U Read follow this for clarifies u r doubt..........
As with business objects, we recommend that you activate the logging of changes to table data for those tables that are critical or susceptible to audits. (See the SAP Audit Guidelines R/3 FI, in Section 4.3.5, for examples of important tables. This document is available at
http://www.sap.com/germany/aboutSAP/revis/infomaterial.asp. You must also explicitly activate this logging. Note the following:
· You must start the SAP System with the rec/client profile parameter set. This parameter specifies whether the SAP System logs changes to table data in all clients or only in specific clients. We recommend setting this parameter to log all clients in your productive system.
· In the technical settings (use transaction SE13), set the Log data changes flag for those tables that you want to have logged.
If both of these conditions are met, the database logs table changes in the table DBTABPRT. (Setting the Log data changes flag only does not suffice in recording table changes; you must also set the rec/clientparameter.)
You can view these logs using the transaction SCU3.
Although we do deliver pre-defined settings, you generally have to modify them to meet your own requirements. Use the report RSTBHIST to obtain a list of those tables that are currently set to be logged. Use transaction SE13 to change the Log data changes flag for these or other tables.
For more information, also see SAP Notes 1916 and 112388.

sudheer.

HOWTO: Expose Entity Object Methods to Clients

By design, clients cannot directly access entity objects. The view object layer provides an extra layer of security--you can choose exactly what data and methods you want clients to see.
This HOWTO describes the process of exposing an entity object method to client programs.
First, if you don't already have one, you must base a view object on your entity object and add the view object to your data model. For full details of how to do this, see the help topics under
+Developing Business Components
--Working with View Objects, View Links, Application Modules, and Clients
+----Creating and Modifying View Objects, View Links, Application Modules, and Clients
For the purposes of this HOWTO, we'll assume that you already have an entity object, Employees, with a method on it, calculateBonus(),
and a view object EmployeesView based on Employees.
First, you must generate a view row class. A view row represents one row of the view object's cache; it corresponds to a view of a particular entity object.
To generate a view row class:
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Java page.
3. Select Generate Java File and Generate Accessors for the view row class.
4. Click Done. This creates a class called EmployeesViewRowImpl.
Next, you should add a "delegator" method to the view row class--a public method with the exact same signature as the entity method, that simply calls the entity method. For example:
public int calculateBonus(int rating) {
return getEmployees().calculateBonus(rating);
Next, you should export this method.
1. Right-click EmployeesView and choose Edit.
2. In the View Object Editor, select the Client Row Methods page.
3. Shuttle the method you just created into the Selected list and click Done.
This creates an interface called EmployeesViewRow that contains your method.
Now you can call the method from your client. You should cast the row returned by EmployeesView.current(), the <jbo:Row> tag, or a similar method or data tag to EmployeesViewRow.
For example,
<jbo:Row id="myRow" datasource="ds" action=Current>
<% out.println(((EmployeesViewRow) myRow).calculateBonus(3)); %>
</jbo:Row>
null

Hi Lisa,
There's a difference between exporting methods (on an application module, view object, and view row--this is done on the "Client Methods" tab of the view object and application module wizards and the "Client Row Methods" tab of the view object wizard) and making an application module remotable (which is done on the "remote" tab of the application module wizard).
You should always export methods you want clients to use--and you only need to do this on the application module if you've written methods on your application module (which I didn't in this HOWTO). You can still use these methods in local mode--the interfaces will be present locally. The advantage of exporting methods is that it doesn't lock you into local mode--you'll be able to change to remote mode later (if you decide that's the way to go) with minimal changes--because the interfaces will be present locally even when the implementation classes aren't.
By contrast, you should only make an application module remotable if you're planning on deploying in a non-local configuration. You can do this step right before deployment.
Hope this helps,
Avrom

Edit entity object and use the Create() method for generating ID's

Hello,
I have and InserPage.jsp and defined the datasoucre correctly.
<jbo:InputText datasource="ds" dataitem="Clientid" /> gives me
the unique ClientID from the FIRST client-record in my table ,
although this page is for inserting a NEW Client, with a new
ClientID.
So, on the Clients Entity i made a create() method and put the
following code in it:
public Number getClientid() {
return (Number)getAttributeInternal(CLIENTID);
public void create(AttributeList attributeList) {
SequenceImpl seq = new SequenceImpl
("Clientid",getDBTransaction());
Integer i=(Integer)seq.getData();
setClientid(new Number(i.intValue()));
super.create(attributeList);
the getData() Returns a sequence value, but what sequence value?
Do i have to create a sequence on the ClientID column in my
Oracle Table in the DB too?
The problem is, the first ClientID # is 819 and the current last
one seems to be 2899, so how do i achieve that when opening the
insert.jsp the new ClientID shows up (ie. 2900)?
How can i achieve this?
thx

OK, managed to track down the HowTo on triggers? I created the
trigger.
create sequence client_seq
start with 8900
increment by 1
nomaxvalue
nocycle;
I changed the create() method for the entity object to:
public void create(AttributeList attributeList) {
SequenceImpl seq = new SequenceImpl
("Clientid",getDBTransaction());
SequenceImpl s = new SequenceImpl("client_seq",
getDBTransaction());
Integer next = (Integer)s.getData();
setClientid(new Number(next.intValue()));
and running the tester for the module works fine. ;-)
But...
The Insert.jsp page has to insert/show this sequenced value!
After i defined the datasource and let us say:
<jbo:InputText datasource="ds" dataitem="Clientid" />
...the number 819 shows up, which is the FIRST record, so i do
not get the new ClientID with the correct number.
Any help is always nice. ;-)

Entity Object Caching!

Hi I am trying to understand what kind of caching an entity object does. Suppose a user issues a query which returns X no of rows utilizing a view Object. If another user issues the same query, will it retrieve from the entity object or go to the database to find it?
What do developers have to do in order to minimize visits to the database?
null

Hi
My understanding is that the query will still be send to the database, the rows returned will be compared with those in the cache, and if they exist and have not been changed the cached objects will be used.
To enable Oracle to prevent queries being submitted to the database the BC4J framework would have to support functionality similar to that provided by Oracle parallel server (and its support for distributed caches) determing whether data had been modified via distributed locks.
I apologise if this is a bum steer, perhaps Development can comment...

Can I use subtype/supertype Entity Object with JHeadstart ?

Hi,
I am using Generalization on our entity object design, i,e : Employee(SuperType), Hourly_Employee(SubType), SalariedEmployee(SubType), Consoltant(SubType). The attributes attached below.
All SubTypes will EXTEND the supertype : Employee.
The questions are :
Can JHeadstart handle the generalized entity objects ?
How can the UI look like with JHeadstart ?
Thank you for your help,
Krist
Supertype : Employee
Employee_Number
Employee_Name
Address
Employee_Type
Date_Hired
SubType : Hourly_Employee
Hourly_Rate
SubType : Salaried_Employee
Annual_Salary
Stock_Options
SubType : CONSULTANT
Contract_Number
Billing_Rate

Krist,
If I understand you correctly you want to have a number of View Object attributes in a page to be accessible through 'subtabs', and want the correct subtab to be shown when the 'discriminator' field is changed. I am sorry for the confusion, I got thrown off track with all the super-subtype Entity details, but in the UI you are only dealing with ViewObject (usages), and not Entity Objects.
Anyway, we can not generate 'subtabs'. There is a feature on our 'Enhancement list' to make the Regions have a 'stacked' property, which I think would come pretty close to what you need: you could group ViewObject Atributes together in Regions, and 'stacked' Regions would be generated as tab pages. We have not implemented this feature yet, and even if we had, you would have to change it post-gen because in your case, you would not want the end user to be able to 'switch tabs', but only a change of the 'discrimitator' field should do that.
We have shipped some templates, though, for creating subtabs for child groups. Perhaps you could take a look if some of that code could be useable for your.
I would suggest the following approach:
1.) In the application structure file, create 'Regions' for all subtypes, and in the BC4J Property Editor, assign the 'subtype' attributes to the corresponding Region.
2.) Regenerate the page. Now you should have a separate 'header' element for each subtype, containing the appropriate attributes.
3.) Now you will need to transform those 'headers' to 'subtype tabs'. You could do that by borrowing code from our 'tabbed child' templates, or, alternatively, you could use a similar, Javascript-based technique that we use for switching between Quick Search and Advanced Search.
4.) Finally, you should device a mechanism to change the active tab when changing the 'discriminator' column in the area above the tabs, with the supertype fields.
Hope this helps,
Peter Ebell

Refreshing Entity Objects after Altering the table

Hi,
My Entity Object is based on a table... and View Objects on the Entity Objects. Now if I alter the table (just changing the width of the column), that change is not visible on the Entity Object. Is there any way I can automatically refresh the Entity Objects after altering the table(only column width is changed).
(Changes made to Entity Objects manually are reflected in the View Object correctly.)
Regards
Faiyaz

'changing the width of the column' means changing the size of the column in the table description in the database. For e.g.. In the original table I had a column OIL_KEY NUMBER(6). Now I change the column to be of size 12 i.e. OIL_KEY NUMBER(12). This does not get refreshed in the Entity Object.

Error while creating new entity object.

Hi all
I'm using Jdev 11.1.1.3. I want to create an entity object and Jdev issues an information error saying "Either this is not a valid name or an object with that name already exists."
I found that if the package I'm targeting for the new entity is called "com.test.model.whatever" I cannot create a EO called "Whatever".
I can't find any reference in the fusion developer guide that constraints the entity names to be allowed.
Is there a way to circumvent this issue or is this the way it should be?

Sudipto and Suresh, thank you very much for your replies.
I know that changing the package or entity name would work, but was expecting some other kind of workaround, something like giving a full qualified name on some xml or something to avoid the name clash or whatever the problem is.
I do not like packing all the entities together as it goes against my best practice of packing things that change together on the same package. Also I don't like suffix or prefix class names as it goes against my best practice of short descriptive names.
So well, I will have to tinker the names some more and meet you guys half way.
I will now mark this thread as answered, thanks again.
