Protocal between ADF Business Service (ADF -AM) and the ADF Faces Model.

Hi,
Anyone knows how the communication is happening between ADF-AM and the ADF Faces model ? I mean the protocol? Is it handling by the application server container with the help of ADF libraries?
I knew in ADF Faces and EJB the communication is hap[ping via RMI/IIOP (standard EJB call). But in the ADF BC and application module i am bit confused about the access. I knew we can expose the AM as state full session bean. But by default how that is happening. Experts please help me to understand the architectural concept of this.

Hi,
the question is not basic and valid too. Just wanted to understand the motivation behind it
For bc4j i am not sure. can we full fill the above deployment scenario?
Yes, you can. ADF BC allows you to deploy the business service as an EJB 2.1 model and then have the Data Control hooking up to it (JNDI).
Apart from this i would like to know the communication protocol (by default) between ADF BC application module and the view model which is the data control. In ejb when we create the data control we can specify that is Local or remote ( Some people said the EJB binding is not full supported in some cases but for ADF-bc it is). But how this is happening in the ADF-BC.
It would work like a normal EJB client. The ADF BC client interface would reside on the web tier and access the remote business service. So there is nothing different here than when using EJB. However, not that it uses EJB 2.1 still and that we don't see customers using this approach in a web deployment. It made lots of sense (performance) in desktop application development with ADF BC, but in web application development a remote business service access doesn't seem to be state of the art (and even using straight EJB you would use the local interface and have the business service model reside on the same machine as the web module)

Oracle ADF Business Service Layer Technologies

Hello,
We are building an online shopping mall/site that is expected to receive order volume of 50-60 thousand orders per week. So obviously, data traffic generated by the site will be pretty heavy. The technology set we are supposed to use is Jdeveloper 10g with ADF. Currently ADF business service layer offers following set of technologies. The question is which of following technologies meets these four criterias the BEST? (1) Security, 2)24x7 Reliability and Maintenace overheads (3)Speed /Performance of the server response to client requests (4) integration with Oracle database.
Please advise. Any technet/metalink oracle document that compares these various business layer technology would be great indeed.
Business service technologies that I am talking about is mentioned below
Enterprise JavaBeans (EJB) Session Beans
Since most J2EE applications require transactional services, EJB session beans are a logical choice because they offer declarative transaction control. Behind the EJB session bean facade for your business service, you use plain old Java objects (POJOs) or EJB entity beans to represent your business domain objects. JDeveloper offers integrated support for creating EJB session beans, generating initial session facade implementations, and creating either Java classes or entity beans. You can also use Oracle TopLink in JDeveloper to configure the object/relational mapping of these classes.
JavaBeans
You can easily work with any Java-based service classes as well, including the ability to leverage Oracle TopLink mapping if needed.
Web Services
When the services your application requires expose standard web services interfaces, just supply Oracle ADF with the URL to the relevant Web Services Description Language (WSDL) for the service endpoints and begin building user interfaces that interact with them and present their results.
XML
If your application needs to interact with XML or comma-separated values (CSV) data that is not exposed as a web service, this is easy to accomplish, too. Just supply the provider URL and optional parameters and you can begin to work with the data.
ADF Business Components.
These service classes are a feature of the ADF Business Components module, and expose an updateable dataset of SQL query results with automatic business rules enforcement.
Thanks

So the quote says "technologies Oracle recommends to J2EE developers" which is correct - if you are an experience Java EE developer the TopLink/JPA/EJB stack should be your choice however if you are coming from a 4GL/Enterprise developer background then the recommendation is here:
http://download.oracle.com/docs/html/B25947_01/intro002.htm#sthref21
For enterprise 4GL developers building new web applications, Oracle recommends using JavaServer Faces for the view and controller layers, and ADF Business Components for the business service implementation. This combination offers you the same productive J2EE technology stack that over 4000 of Oracle's own enterprise 4GL developers use every day to build the Oracle E-Business Suite. Since its initial release in 1999, several thousand external customers and partners have built and deployed successful Oracle ADF-based applications as well. Both now and in the future, Oracle and others are betting their business on Oracle ADF with ADF Business Components.
And yes ADF BC can be exposed as EJB - but this is usually only used for remote deployment of ADF BC when they are on another server than the UI code - for example when using Swing.

Data sharing between region and the ADF page which contains it

Here I've got an ADF page, on which there is a region. Suppose the region corresponds to the backing bean A and the ADF page corresponds to backing bean B. Now I need to make use of the variable (e.g., var_a) in the region the pass it to the backing bean of the ADF Page's backing bean B.
How do I achieve this? Any comments will be highly appreciated.
Regards.
Edited by: isaacniu on Apr 5, 2010 8:05 PM

Hi,
the propery way to communicate back fom a region into the calling page is to use contextual events, which is a publish/subscribe system implemented on teh ADF binding layer. If a bean is configured in a standrad servlet scope (for example request or session), thus not bound to a specific occurence of its instance (backingBeanScope) then you could pass the EL string as an input argument to the task flow and use a ValueExpression in the managed bean of the region to resolve it and call a setVariable method to pass a value to it.
For example, if the managed bean is MyManagedBean, then you could pass
#{'#{MyManagedBean}'}
as the task flow input value. This then e.g would be written to the pageFlowScope.externalBeanref attribute (you need to do this in the input parameter mapping) from where it can be accessed by the inner managed bean (the bean of the region).
Note that the above is a "little dirty" but works. The reason why I suggest to use an input parameter instead of directly coding the EL to the parent page managed bean into the bean of the region is encpsulation: you don't want to make the bounded task flow in the region dependent from the outer parent context.
Frank
Ps.: Note that the managed bean is created when it does not exist. If you want to avoid this, you could pass #{'#{requestScope.managedBean}'} into the task flow. In this case, if the managed bean is not instantiated by the parent, the EL Value Expression comes out "null" if the managed bean wasn't instantiated before, in which case you know that there is no sense in accessing a setter/getter on it.

Can we use same Business Service for Sender and Receiver

Can we use same Business Service for Sender and Receiver

Hi
In addition to the above infomation explaining about the Business Service..
Business Service: Address an abstract business entity as the sender or receiver of messages.
Using a business service, you can define the technical or business subunits of the companies involved and then assign them the relevant interfaces.
The business services are used when configuring cross-company processes also..

I am assuming that the primary key that you were referring to is the SEARCH_ID.
Caused by java.sql.BatchUpdateException: [IBM][CLI Driver][DB2/LINUXX8664] SQL0798N A value cannot be specified for column "SEARCH_ID" which is defined as GENERATED ALWAYS. SQLSTATE=428C9Looks like when you generated the JCA DBAdapter WSDL, all the columns were selected. And hence the insert queries that were generated to be used by the JCA DBAdapter have this field.
Can you reconfigure the DBAdapter with a custom query to insert in to the table, without the primary key column selected. This should resolve your issue.
If this still does not solve your issue. Lets start to debug further by capturing the exact SQL query being executed.
Enable the debug mode for the JCA framework. Edit the alsbdebug.xml file in the domain directory and set the category alsb-jca-framework-adapter-debug flag to true. Then restart the servers.
Refer - http://download.oracle.com/docs/html/E15867_01/app_debugging.htm for more details.
Hope this helps.

I bought an IPAD air from state and the screen is not working correctly and right now i'm in Egypt ,can i send my ipad to service in Egypt and the warranty will work in Egypt or what?

i bought an IPAD air (32 gb wifi only) from USA just one month ago and the screen is not working correctly(picture attached) and right now i'm in Egypt ,can i send my ipad to service in Egypt and the warranty will work in Egypt or what?

Have you tried a soft-reset to see if that fixes it ? You might be able to get warranty service in Egypt for your iPad, but the warranty includes :
IMPORTANT RESTRICTION FOR iPHONE AND iPAD SERVICE.
Apple may restrict warranty service for iPhone and iPad to the country where Apple or its Authorized Distributors originally sold the device.
As it's wifi-only you should have a better chance of it being serviced under warranty, but there are no guarantees, it might depend upon the repairer.

Two days ago most of my music dissapeared from my Ipod, however all of it is still in my iTunes Library. After synchronizing the Ipod there is a huge difference between both music in my library and the one in the Ipod.

Hi Rodobaldo,
Let's try to clear up this issue for you, I'd like to clear out the music on your iPod first. You'll want to find the Sync Music Checkbox, uncheck it, then Apply or Sync:
Once you have done that, recheck the "Sync Music" checkbox, and apply the changes once more. This will instruct iTunes to completely remove all music from your iPod nano, and then copy the files once more. If you have a large amount of music, this initial sync may take a while.
If the above does not resolve your issue, see the following article:

I have a 4th gen iPad and the type face on the keyboard has been replaced with small squares. How do I fix this?

Try this - Reset the iPad by holding down on the Sleep and Home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider - let go of the buttons. (This is equivalent to rebooting your computer.) No data/files will be erased. http://support.apple.com/kb/ht1430

Restart with the Option key held down and see if the internal drive appears.
If it does, click on it, press Enter, and then change the setting in the Startup Disk pane of System Preferences or the Startup Disk control panel.
If it doesn't, insert a Mac OS install CD or DVD and use the Disk Utility or Disk First Aid to repair the internal drive. If there aren't any problems, install an OS onto it.

Conflict between 2 business services for the same SAP R/3 instance

Hi,
We developed a packaged solution that connects to SAP R/3 with RFC Adaptor and idoc Adaptor.
We deliver design and configuration packages defining the entire integration schema between an external system and SAP.
The configuration defines a business service BS_SAP_R3 containing RFC and idoc communications channels.
When we deploy and configure the solution (design and config) on a XI instance we have a conflict.
As the XI already contains a Business Service connecting to the same SAP instance (other integration) we want to use with our business service BS_SAP_R3, we have an error when configuring the Adapter-Specific Identifiers properties R/3 System ID and Client from the section IDoc Adapter and RFC Adapter with the message, for the BS_SAP_R3
Check Result for Object BS_SAP_R3
SAP system ID D46 and client 800 already exist in service | BC_TEST_SAP_R3 
Is there a way to solve this conflict problem?
Thanks for your help.
Adalbert

Dzieki za odpowiedz
Could you give more details about the design issue and what you have on mind?
I also suspect a design issue but do not know how to solve it...
If in your Configuration you have 150 Receivers Determinations, Interface Determinations and Receiver Agreements referencing the same BS business service to access SAP, can you make the service configurable in any sort
Can you recommend another solution?
The only solution I see it to regenerate all the configuration by hand using the already exiting SAP BS But for 150 objects it is not a real solution...
Thanks for your help

ADF EBS Integration - How to open the ADF page in new tab or window

Hi,
We are building ADF custom applications and want to integrate them with EBS R12 (12.1.3) through Responsibilities and Menus.
We have achieved session sharing and launching the Custom ADF app from EBS menu. The problem is, the Custom ADF page opens in the same page.
Is there anyway to open the ADF application in new tab or window while launching from EBS Menu ?
Highly appreciate your help on this.

SAP Business Workflow and The Workflow Reference Model

Hi Experts,
I try to map the Business Workflow with the Workflow Reference Model of WfMC.
Interface 3 represents the communication of SAP's Workflow Engine with "Invoked (external) Applications".
My Questions are:
- which applications, tools can be invoked (Webservices, Group Ware Products)
- and which component realizes Interface 3?
(can I say that interface 3 is realized with different steps like web-activity,
or the normal activity-step (WebFlow Service Handler) ? )
Or is there a certain technology that is representative for realization of interface 3 ? e.g. WfXML or SOAP?
Thanks in advance

Service module placement and the L2 adjacency problem

I'd be very interested to hear others opinions on this. You have a datacenter environment with L2 boundaries at end of row aggregators, then L3 back to the core and edge. You have 6500 service module switches hanging off the core housing ACE and FWSM modules. You want to offer firewalling and load-balancing services to servers around the datacenter.
What is the current best practice ways of resolving the L2 adjacency requirement that the firewalling and load-balancing services impose? L2TPv3? EoMPLS? Any relevant advice, deployment examples, whitepapers etc would be much appreciated!
Thanks for any replies,
George

George
You could i suppose look to use L2TPv3 if your switches support it or EoMPLS but to my mind this is actually using a band aid to fix a problem that shouldn't be there.
We too struggled in our data centres with this setup but remember you only need L2 adjacency if you are running the FWSM in transparent mode or the ACE in bridged mode.
If you are then the cleanest solutions are either
1) redesign core connections to L2
2) deploy 6500 switches in the distribution layer. I say distribution layer because it's not clear from your description what your topology actually is but i'm assuming L2 access to distro and then L3 distro to core and the core switches are the 6500 switches.
Personally i always use the routed L3 approach where possible for fast failover and no STP and in the campus environment it works really well.
However L3 from the access-layer to the distro in the data centre is very limiting and you often come across problems such as the one you are facing.
Now again it does depend on your topology but assuming the issue is your core is L3 connected and you need L2 adjacency with your distro to offer servers i would look to deploy 6500 switches in the distro layer with the service modules in them.
If i have misunderstood please come back with more details.

Business Rules: Account transformation and the source YEAR / PERIOD

Ladies and gents,
lets assume you have an amount of 100 on account A everymonth for 2 years.
in my business rules, account transforamtion, i put those sales to be transfer to an account B.
When i put DEC in period and -1 in year, then it will post the previous year cumulated amount of A to B. So be will have 1200
Now, lets assume I put 9 in period and -1 in year then it will bring me the total of previous year October if i am in january Y1, or previous year November if i am in february... But then in march, april, ... until the end of the year it will bring previous year December.
Now, when i put -3 in period and no change in year, for january, it brings january, for february it brings february, for march it brings march... But on April it brings january as expect...
I want it to come with 0 for the first 3 month... and only start in april!! Why does it do that considering that it for the previous example +3 after march always brings december... why then -3 in january doesnt bring nothin!!
Nic
