  • HOW to Interact with Oracle HRMS applications from BPEL..

    Hi friends...
    Well...i just wanted to know HOW easy is it to interact with an Oracle HRMS application from within a BPEL process...
    [Say, my BPEL process has some approvals from Finance Dept.., but i need to contact some application like Oracle Payroll, for some data...]
    I think we would have to use some Application Adapter Service for this..but not sure..!
    Would be great if anyone could refer me to some links or guide me in this regard...
    Thanks...

    Hi,
         You can read the data using "Middlware Tools" like XI,Business Connector,Mercator,Webmethods
          and using DB-Link.
          If you want Read the data using ABAB coding, you need to use "Native SQL" Stament.
         For XI and other Middlware , you need configure so many steps,(RFC defination,PORT,Partner)
         Required. 
         Through ABAP Program :
         Befor creating program , You need to find out "Oracle Server Name and Other details.
          Please use below code as your reference.
    Open a native SQL connection.
    EXEC SQL.
    connect to 'ONECD'
    ENDEXEC.
    Retrieve information from the BVER tables.
    EXEC SQL PERFORMING read_dental.
    select emp_ssn_num, emp_fname, emp_lname,
    to_char(start_date, 'YYYYMMDD') as start_date,
    rec_type,
    to_char(eff_date, 'YYYYMMDD') as eff_date,
    vendor_plan_id
    into :dental
    from opr$8oc.BVER_CURR_DENTAL_MASTER
    ENDEXEC.
    EXEC SQL PERFORMING read_medical.
    select emp_ssn_num, emp_fname, emp_lname, rec_type,
    to_char(start_date, 'YYYYMMDD') as start_date,
    to_char(eff_date, 'YYYYMMDD') as eff_date,
    network_code, pcp_number, patient_flag,
    vendor_plan_id,
    to_char(network_eff_date, 'YYYYMMDD') as
    network_eff_date,
    to_char(pha_eff_date, 'YYYYMMDD') as
    pha_eff_date
    into :medical
    from opr$8oc.BVER_CURR_MEDICAL_MASTER
    ENDEXEC.
    Disconnect from the native SQL connection.
    EXEC SQL.
    DISCONNECT 'ONECD'
    ENDEXEC.
    The system log has messages like 'Work process is in reconnect status' and 'Work process has left reconnect status' after the ORA-02396 message. And I specifically do a disconnect at the end and a connect at the beginning, but it looks like it is trying to do a reconnect?

  • How to call a PL/SQL procedure from a Java class?

    Hi,
    I am new to the E-BusinessSuite and I want to develop a Portal with Java Portlets which display and write data from some E-Business databases (e.g. Customer Relationship Management or Human Resource). These data have been defined in the TCA (Trading Community Architecture) data model. I can access this data with PL/SQL API's. The next problem is how to get the data in the Java class. So, how do you call a PL/SQL procedure from a Java program?
    Can anyone let me know how to solve that problem?
    Thanks in advance,
    Chang Si Chou

    Have a look at this example:
    final ApplicationModule am = panelBinding.getApplicationModule();
    try
         final CallableStatement stmt = ((DBTransaction)am.getTransaction()).
                                                                                         createCallableStatement("{? = call some_pck.some_function(?, ?)}", 10);
         stmt.registerOutParameter(1, OracleTypes.VARCHAR);
         stmt.setInt(2, ((oracle.jbo.domain.Number)key.getAttribute(0)).intValue());
         stmt.setString(3, "Test");
         stmt.execute();
         stmt.close();
         return stmt.getString(1);
    catch (Exception ex)
         panelBinding.reportException(ex);
         return null;

  • How to get properties of a bean from another java class

    Hi,
    I am new to JSF. Currently I am facing a problem, and hope you experts can give me some guidance.
    The JSF app i am working on has one Java class for handling a tree structure, MyTreeNode.java, and it also has a bean, NameBean.java, which has two properties, username and password.
    I can easily associate an input text with the #{name.username} to store the user's login... but later on, I need to fetch that information inside of MyTreeNode.java. How do I do that? Thanks!

  • How can JSP access a COM+ component

    I have to develop JSP pages that leverage existing Microsoft COM+ components. Can anyone suggest a good resource or provide me with a quick explanation/overview of how I would access a COM+ component from JSP? I'm getting exhausted searching the internet for answers only to come up empty. Thanks...

    I use Neva Object (www.nevaobject.com) for this sort of thing. This is a commercial product. The product does what it says it does and that is as far as I will endorse it.
    Since purchasing it I came accross
    http://staff.develop.com/halloway/code/jawin.html
    This looks like it will do much of the same thing but is more suitable for scriptable COM objects. It is also an open source license.
    I don't have any experience with jawin but the support community looks strong. Checking out their website will be worth your time.
    Good luck

  • I am having much trouble with the new reminders in IOS7 and how it interacts with Outlook Exchange. Many features lost in the new version.

    When I downloaded IOS7, I found that the reminders/task app and how it interacts with Outlook Exchange is much more difficult to use. Some of the issues that I am having are...
    1. Trying to edit my task on my phone is not possible, if the notes are lengthy. When you click on the text to edit data near the top, it will scroll to the bottom and not allow you to edit the text because you cant see it.
    2. Now all of my task are in one long list. I can not move from day to day like we could in previous version IOS6
    3. When I do edit a short task reminder and click done, it crashes and completly goes away. It does save the edit though
    4. You can only add task at the bottom of each days reminders. This is very inconvient and much more difficult than IOS6
    5. There is a major delay or latency when interacting inside of reminders in this version. Much more than IOS6. It is very unstable and quirky.
    I have never seen Apple take a step back with a product until now. I am a huge Apple fan and always will be, so I am hoping they make enhancements to fix these issue. It is a big time prodcutivity killer.
    Thanks for any and all help you can give.

    Some power supplies or designed so that if there is a short or overload they shut them selfs off and some will not turn back on. Some have a relay that will click back on and work, some you have to  cycle the power switch. Those that won't come back on will have to be replaced. I'm not saying that yours is that type as I have no way of telling. But if you have a friend who will loan you a good power supply you might try it. As someone else said just turning off the power will not darn all the power from some motherboards. To test this turn off your power supply than turn on the computer with the start botton. Mine will flash the lights and fans will start to spin than die. So every time you turn off computer to work on it. After turning off PSU hit the start botton to drian any power left in it before working on it. Also do this after unplugging it just to make sure.

  • How to interact with database?

    Hi,
    I am exploring sampleportal application in Weblogic Portal8.1 SP4. There in login portlet they are using login.jsp file which uses examples.login.DirectorBacking class for login form authentication. DirectorBacking class uses default com.bea.p13n.security.Authentication class’s authenticate method for authentication. I could not understand the basic functionality of Authentication class as how it interacts with the database.
         Can we use simple JDBC for the login authentication in login.jsp ?

    U can define several authentication realms - which could be RDBMS, LDAP etc.
    Does that answer your question?

  • Using COM component from EJB

    Hi,
    I'd like to use a third party COM component from. I know JIntegra and such tools but I'd like to use a non-commercial software as I need it for my diploma thesis.
    Did anyone ever manage to call an ActiveX/COM component from an EJB. I mean a third party component, not a self developed one.
    Could I use M$ specific classes in my EJB or do they rule out each other?
    Any working example?
    TIA
    Frank

    Did you really manage to use third party DLLs with EZJCOM?
    Would be great if you could clarify this to me:
    If I would use M$ specific classes to have a Java / COM - communication then I would
    have to use M$ JVM, right?
    But if I use that VM, I can not use my classes within the J2EE / EJB environment as this
    requires Sun's JVM, right?
    So, if I use EZJCOM for that than I do not have to use any M$ specific stuff, right?
    Unfortunately, I did not get any further yet. The product I'd like to use is Lindo.
    I have the DLL, but trying to use it with EZJCOM it says: No COM interface definition.
    No tlb is given either. There's a JAR package with classes that seem to use JNI to call
    DLL functions, so maybe it does not provide a COM interface.
    But that means I would have to build my own (maybe VB) ActiveX DLL that calls all the funtions
    in the Lindo DLL. But that would keep me busy for weeks I guess :-(
    As I need it for my diploma thesis, I can not spend a lot of time building ActiveX components.

  • How to deal with Cash Deposited/Withdrawn from Bank

    Gurus,
    How to deal with Cash Deposited/Withdrawn from Bank for office use.
    <b>Here is the senario:</b>
    When Cash is deposited in Bank the entry is
    Bank Main A/c Dr
    To Cash A/c
    and when Withdrawn from Bank the entry was
    Cash A/c Dr
    To Bank Main Account
    Now my question is, How we will deal with these transactions while creating Bank Reconcilation Statement. As per my knowledge.
    Bank Main Account Balance = Sum of all Bank Clearing Accounts.
    If the difference occurs with cheques we deposit it or make note of issue while BRS, which effect the Clearing Accounts, But, How about Cash Deposit and Cash Withdrawn, coz these won't effect any of the Clearing Accounts.
    How do deal with this.
    please advice.
    Satish

    Hi Satish,
    Through FBCJ transaction you can do the cash receipt / cash payment to Bank (Bank clearing Account). By using the Business transaction "Receipt from Bank" and "Payment to Bank".
    Hence bank posting will happen in the Bank clearing account. As soon as BRS is done, it will hit the Bank Main account.
    Hope it is clear for you. If my reply is useful than please assign points for the same.
    Thanks & best regards,

    I's an encapsulation for the JavaScript code required and hides the separation between frontend and backend. There was a reason why so many developers stick to the MVC-pattern wich ist violated here.
    I did not know it is not possible to do the same thing in Java.I'ts not a task of the backend to layout the user interaction GUI.
