How Business service layer is useful?

Hi All,
What advantage are we getting with Business Service Layer in ADF? Cant we have just simple model layer? Why there is a separate business layer? why it is not part of the model layer?
Thanks.

Yet another homework question?  Again, go do some research.

  • 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.

  • Do I use Service Catalogue or Business Services for this?

    Hi
    I'm just looking at implementing System Centre Service Manager - I'm an ITIL expert but not a Microsoft techie so bear with me!
    I need to represent 130ish Services within SCSM which are different products we sell and support for our clients. Incidents, changes, releases etc will then be logged against these services, not the individual chunks of hardware.
    How and where do I set these up in SCSM?? I had assumed it was setting up Business services? Is that correct?
    Do the business services initially have to be associated with hardware held in SCCM or can we have a POC with a standalone service?
    A bit fat pointer would be usefu right now!
    Thanks

    You are right: Business Services can be used for this.
    You only need to specify a Display Name for the new Business Service. No other information are mandatory or requiered to create a Business Service in SCSM.

  • Proxy & business Services creation using XML

    Hi,
    can we create a proxy service & business service in OSB using an xml? usually we use to create using a WSDL defined by a webservice. can we create it using XML ? If so can anyone provide the doc or link for that.
    thanks

    You may create XSD from XML and then create WSDL from XSD using JDev. Using that WSDL you may create proxy or business service in OSB.

  • How to make message transfer to a topic from a business service synchrouns?

    hi,
    I am posting a message to a JMS queue using a business service (say A) and then I am fetching that message from that queue and using a proxy service (B) and a business service (C) for transferring that message to a topic, now I want that my business service A gets the same message that it initially posted as a response back from the topic to make the whole message transfer synchronous, but the problem is that as I select topic on my JMS transport configuration page of business service the text box where I need to specify the URI for the topic gets blocked,hence I am unable to get a response from the topic, can anybody help me out with this as I really want to make this synchronous.
    Edited by: user12826319 on Jul 21, 2010 4:36 AM

    yes u got it correct...v require a synchronous message transfer to happen i believe d alternative can be that i send the message to topic directly using a business service and expect a response from the topic itself in the form of the message i initially posted, that thing I would manage but the real problem is to get a response to the business service when i use topic, because as i select topic on JMS transport configuration page of business service the end point URI textbox gets blocked...

  • Custom hostname verifier not used when business services use a http proxy

    On OSB 10.3, we have a business services with an https end point. To access this end point, the business service used an http proxy.
    The certificate of the business endpoint is a wildcard certificate *.certificate.be . So we have a custom hostname verifier defined in the ssl configuration on the weblogic Server
    As we can see with the verbose mode at the jvm, the custom hostname verifier is not used when we use a http proxy in the business service. Osb use a ALSBHostnameVerifier and this one the defaulthostName
    <Mar 2, 2011 7:31:11 AM CET> <Debug> <AlsbTransports> <BEA-000000> <*** Connecting via proxy *** HTTP @ my.proxy.be/XXX.XXX.XXX.XXX:8080>

    Is there any way to force business service to used hostname verfifier defined in weblogic ssl server config?

  • Design -  service layer

    Example model:
    Manager - > Employee - > Result
    Manager has a list of employees . Employee has a list of results. Each entity is " heavy " entity.
    I need to create a service layer for getting objects from my module.
    this service layer will used by other modules in the product.
    The issue that i want to get an ideas and reference is how to define the interface.
    How do i define what to fetch with the object? Do you have specific API for fetching different objects graph.
    For example:
    getManager
    getManagerWithEmployes
    getManagerWithEmployesAndResults

    For example:
    getManager
    getManagerWithEmployes
    getManagerWithEmployesAndResults
    It depends on the business requirement or the uses cases ( senarios ); for example if an actor is interacting with the system, the actor wants to view all current managers who has less then 5 employee or how has employee with salary above 100 etc..
    or another senario which is an actor want to generate reports which shows all managers with there employee; then the actor go further to look into details for each employee( salary, age, gender)
    so there is on specific api but rather you start to build your api based on uses cases i.e senarios ( write them down) so start with some rough senarios and
    then move into defining your business service interfaces then try to implement the interfaces.
    After a while, you discover that you need different senarios ( business requirement changes), then you go back and do the same as above ( iteration ) senarios, interfaces then implementation
    Hope this make sense to you

  • Diff. between Business service & Business system.

    Hi All,
    Can anybody tell me what is the actual difference between Buss. service & system ? and in which case I should use either ? How can I differenciate this two ?
    Eg. 1. I am using Buss. system BS1 , than what/where this BS1 should  be ?  and 2. if am using Buss. service BS2 , than what/where this BS2 should  be ?

    Difference:Difference between Business System and Business Service
    Business Service
    1) You use a Business Service, when you do not have the System details of the the partner system to which you want to communicate. i.e. you have not configured the partner system in SLD.
    2) Business Service is an Absract Unit with Sender and Receiver Interfaces,In this case you need to explicitly add the message interfaces while doing configuration in ID.
    3) It is generally used for NON-SAP applications, this is just a general prinicple followed but not mandatory.
    4) This is not defined as part of SLD and whose technical parameters are not completely known.
    5)Business service is used when the message is not addressed to a business system. It is used mostly in B2B scenarios.
    Business systems:
    Business systems are logical systems, which function as senders or receivers within PI. Business systems can be SAP systems or third-party systems.
    Depending on the associated technical system, the following types of business systems are defined in the SLD:
    Web AS ABAP:
    A business system, which is associated with a Web AS ABAP.
    A business system, which is associated with a Web AS ABAP, can play the role either of an application system or an integration server. An integration server is the central component of PI, which provides a framework for the exchange of information among various internal and external entities of a company. The integration server facilitates the interaction between the different operating systems and applications across internal and external networks.
    Web AS Java:
    A business system, which is associated with a Web AS Java.
    Standalone:
    A business system, which is associated with a standalone Java application.
    Third-party:
    A business system, which is associated with a third-party technical system.
    Technical systems:
    Technical systems are application systems that are installed in your system landscape. An example of an application system is a Customer Relationship Management (CRM) server. In the SLD, there are five types of technical systems:

  • Business Service and logical system naming criteria across environments

    Hi !
    Imagine this scenario: File-XI-IDOC. There is a file server where files are uploaded by a legacy application. XI polls that directory, converts the file to IDOC and sends it to R/3.
    R/3 is a production business system, for example "R3_PROD", the file server is a business SERVICE, because of its abstract nature.
    Is it ok to give that business service a name such as "BS_FileServer" and then create the logical system "LS_FileServer" in R/3, to be able to receive IDOCs from the sender business service?
    If we need to use 3 different file servers, one for development, one for test and another for production...is it ok to create the business service in each integration directory with SAME name, and the 3 logical systems with same name in each R/3 receiver...because creating business services as "BS_FileServer_DEV", "BS_FileServer_TEST" and "BS_FileServer_PROD" we imagine that could give us problems when transporting scenarios from dev to test, and from test to prod...because we will need to recreate the whole scenario using the new object denomination.. e.g. a scenario including BS_FileServer_DEV in development is called BS_FileServer_TEST in test..or worse..we could have the BS object transported and as a result we would have a BS_FileServer_DEV object in integration directory of our test environment...
    Is this the right path?
    Thanks,
    Matias.

    Hey,
    When a technical system is defined  for a product / s/w comp version we also enter the parameter for logical system name. If a buisness system is defined for a technical system then it in turns refers to the technical system with buisness system assigned to it.
    Itz lyk linkage of  <b>PRODUCT -> S/W COM VERSION -> TECHNICAL SYSTEM (LOGICAL SYSTEM) -> BUSINESS SYSTEM</b>
    As per file to idoc scenario where <b>BUSINESS SERVICE</b> is used it doesn't refer to technical landscape so there is no question of Business system. With relevance to transports.
    With File -XI-Idoc scenario the concept of logical system only comes into picture if we have  a integration process also involved in the scenario. Where in adapter specific identifiers we specify the logical system name of the sender file system.
    Integration Repository.
    1)  The Software Component version need to be same in all the landscapes that is a prerequisite else transport will fail.
    Integration Directory:
    2) Assuming that transport is being done for all the objects under a service and the objects has been transported to the test landscape business service with same name will be create in test sys only address and access parameters that have to be entered again and the change list has to be activated.
    I haven't  tried exporting individual object from ID so no clue.
    Please refer the following link<a href="http://help.sap.com/saphelp_nw04/helpdata/en/93/a3a74046033913e10000000a155106/frameset.htm">Transporting XI Objects</a> .

  • Business service or Business system??

    Hello All,
       I do get confused with respect to Business service and Business system?? What differentiates between them and when accordingly are they used??
      If I am using a HTTP adapter to connect to a URL address of a 3rd party system, what would be my steps in Intergration directory involve?? I get lost in receiver determinations and interface determinations and their purpose...
    Thanks,
    Kenneth

    Hi Ken,
      Basically business service will be used only for published services and not those which  have a physical landscape set up. If there is a physical landscape available then we go for business systems.
      Receiver determinations talk abt the receivers available for an outbound interface and interface determination tell you abt the interfaces ( both outbound and inbound) in play and their mapping pgm involved.
    Hope this was helpful and any add ons are also welcomed.

  • Whats the actual difference between Business system and Business service

    whats the actual difference between Business system and Business service

    Business System
    1) Business system is a logical system, and there is an importance on physical existence of the system.
    2) Also SLD entry is required.
    3)It is generally used for SAP applications, this is just a general prinicple followed but not mandatory.
    4)This is defined as part of the SLD and is a physical system whose parameters are well defined.
    5(Business systems refers to the physical systems, for instance the R/3 system. You define the business systems in the SLD
    Business Service
    1) You use a Business Service, when you do not have the System details of the the partner system to which you want to communicate. i.e. you have not configured the partner system in SLD.
    2) Business Service is an Absract Unit with Sender and Receiver Interfaces,In this case you need to explicitly add the message interfaces while doing configuration in ID.
    3) It is generally used for NON-SAP applications, this is just a general prinicple followed but not mandatory.

  • Diff between Business service and Business System?

    HI Experts,
      Pls let me know wht is the difference between business service and business system??
    when we will have to go for business service and when for business system??
    thnx in advance..
    New XI

    Hi,
    Difference between Business Service and Business System are :
    1) Business sytem require all details like login user id
    password require to create but in case of business service
    log in details does not require..
    2) A Business System  is purely for SAP-Systems and
    Business Service for Non-SAP systems
    3) Business service refers to any business applications where
    as the business system is defined in SLD(System Landscape
    Directory)
    4) When we have full details of application system the we are
    going to use the business system and it is created in the
    SLD so we dont have authorization to change the business
    system name.
    When we have partial details or no details of Technical
    system then we r going to use the business service. it is
    created in the ID. we can see and change it.
    5) A Business system is something that physically exists
    For example, if u want to download a file from a system
    ABC, by using file adapter and then want to update the
    content of this file into r/3 database by using RFc,then
    the system  abc and the r/3 will be ur business systems
    i.e. they physically exists. Business Systems are
    configured in SLD.
    Business service is mostly usedin B2B Scenario (cross-
    component),where you don't know the Business System of your
    partner. In other words business Service will be used only
    for those partners which do not have a physical landscape
    set up . Business servces do not have an entry in SLD.
    6) A Business Service is an Abstract Unit(which is not in
    System Landscape Directory) addressing Senders and
    Receivers of Messages.
    Physicals systems which use their communication channels
    and routing rules to communicate with other systems are
    called as Application Systems OR physical systems.
    7) In simple when u going for A2A integration then we define
    our Technical systems are Business system. If we r going
    for B2B integration then we dont know the complete
    information about the other end Business Landscape so, we
    configure it as a Business Services. Business system are
    created at SLD. Where as a Business Services are created at
    Integration Directory.
    8) Business systems:
      These are logical senders or receivers that exchange
    messages by using the Integration Server and that are
    entered in the System Landscape Directory.
    The business systems in the System Landscape Directory
    relate to a system landscape. The business systems of
    business partners are therefore not entered in the System
    Landscape Directory. To be able to address such business
    partners logically, use communication components in the
    Integration Directory. A business system is a way of
    specifying a communication component in the Integration
    Directory more precisely (business system component).
    Hope this will hwlp u..

  • Calling a Business Service from a Web Template File

    I'm attempting to call a Business Service from my .swt
    I've tried everything I can think of and can not get this to work for the life of me.
    I've looked endlessly for information on this topic to no avail.
    the swt call looks something like this:
    <swe:case condition="My Business Service Name, My Business Service Method">
    </swe:case>
    I assume it is something to do with the set-up of my Business Service. Could someone please help me out here or point me to some information on this topic that is actually helpful? (The bookshelf, from what I could find, did not go into setting up the business service for this use at all)

    Hi Diz,
    I tried doing the same thing by following the steps as mentioned by you. Just to re iterate,
    1. Created a DC "Portal Application Standalone" project by the name myservice.
    2. Created a portal service inside myservice by the ame AmitsService.
    3. Exposed IAmitsService.class in the public part.
    4 Build and deployed the DC on server and tested it through an abstract portal component and it worked FINE !!
    Now..
    5. Created anoter DC of type WebDynPro
    6. Added SAP_JTECHS -> epbc.prtapi._api as a "Used DC" with dependency build time and runtime
    7. Specified the sharing reference in the properties as PORTAL:sap.com/myservice
    8. Tried to reference the service using the following code..
    IAmitsService portalservice=(IAmitsService)WDPortalUtils.getServiceReference(IAmitsService.KEY);
    9.Build and deployed the DC.
    10. When I run the application I am getting the following error
    Processing HTTP request to servlet [dispatcher] finished with error.
    The error is: com.sap.engine.frame.core.load.SAPNoClassDefFoundError: com/sapportals/portal/prt/service/IService
