Hello
thanks for the link. But is not telling me what I want.
I dont have java in my computer. I will be supplied with a java API name which I have to call by connecting to remote server. I will be have the username and password to connect and call the remote API. I need to get the return value from the remote Java API in my PL/SQL. I hope I have explained the issue clearly.
Thanks again.

  • Calling a Java Function from PL/SQL

    Hi,
    I would like to call a Java API from a java class residing on the middle tier ($OA_JAVA)

    Documentation here: http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref185
    says JPublisher can publish records too.
    But when I change the example given at http://download-uk.oracle.com/docs/cd/B14117_01/java.101/b10983/datamap.htm#sthref190 as following:
    PACKAGE "COMPANY" AS
    type emp_rec is record (empno number, ename varchar2(10));
    type emp_list is varray(5) of emp_rec;
    type factory is record (
    name varchar(10),
    emps emp_list
    function get_factory(p_name varchar) return factory;
    END;
    then I see <unknown type or type not found> at sql or java files generated. Any ideas?

  • Calling Java API from ABAP using JCo (Part 2)

    Hello,
    This is an additional question to thread Calling Java API from ABAP using JCo
    Has anyone managed to get the input parameter value
    input.getString("REQUTEXT")
    that is being passed from ABAP?
    If yes, what kind of setting you need to do? Because when I execute, it has no value.
    Thus, the below ECHOTEXT parameter returns blank value:
    output.setValue(input.getString("REQUTEXT"),"ECHOTEXT");
    When I debug by printing the below line, the input XML is indeed without value:
    System.out.println(input.toXML());
    Anybody knows how to pass input variable from ABAP to JAVA using JCo?
    rgs,
    hiroshi

    Hallo Hiroshi,
    as far as I can see, you are doing it the right way. The problem might be that the ABAP program does not fill in this parameter because something went wrong in the SAP System.
    Have you tried setting a breakpoint (an HTTP session - remote breakpoint) and tried checking step by step if the value is being processed and put into the REQUTEXT field?
    Bye,

    First, to call a Java class from PL/SQL the class needs to be
    deployed to the database. you can check the 8i documentation for
    the instructions for loading Java into the database(LoadJava).
    The document contains information on how to load the Java and
    call it from PL/SQL. The following links should help.

    Hi Nilesh,
    From the error i think that the error is with the hostname.
    Please enter the the Application Server IP/Hostname.
    If you are loggin to SAP System "XX1" from SAP GUI. Then click the change Item tab and see Application server name/IP let say "XX2" for hostname or "xx.xx.xx.xx" for IP.
    Replace <i>srv[0] = new Server("gateway","sapgw00","JCOSERVER01",repository);</i>
    with <i>srv[0] = new Server("XX2","sapgw00","JCOSERVER01",repository);</i>
    If App Server is IP then replace with
    <i>srv[0] = new Server("xx.xx.xx.xx","sapgw00","JCOSERVER01",repository);</i>
    Let me know if it is throwing any error.
    Thanks,

  • How to call Java API from BSP?

    I have a requirement to call Java API from BSP application.
    I have checked the forum and found that it is possible by using some ABAP codes.
    However there is no pointer on how this is done.
    Can someone explain the details on how to call Java API from BSP is done?
    I found class CL_EJB_JAVA_OBJECT_METHODS to call a method in EJB but can't find function or SAP class to call Java API.
    Actually is there any BSP extention which can used to call Java API?

  • Can I call a Java program from a SQL Server Trigger?

    Hello,
    I want to encrypt some data in a database column in SQL Server. Today I am using java code to encrypt the value and store it in the database using JDBC.
    Now I want to use a VB client to store the encrypted value in the SQL Server DB. Since the encryption is handled by a java class, can I write a trigger in SQL Server that while inserting the raw data, calls the java class for encrypting the value and then inserts the encrypted value into the column?
    In general, is it possible to call a java class from a SQL Server trigger?
    Thanks
    Bipin

    Here are 3 examples of code for insert, update and delete:
    CREATE TRIGGER [PLI_INSERT_TRIGGER] ON [dbo].[PLI]
    FOR INSERT
    AS
    Declare @cmd sysname, @code sysname, @list sysname
         Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted
         Set @cmd = 'java mirrorDb.Copy PLI INSERT ' + @code + ' ' + @list
         EXEC master..xp_cmdshell @cmd
    CREATE TRIGGER [PLI_UPDATE_TRIGGER] ON [dbo].[PLI]
    FOR UPDATE
    AS
    Declare @cmd sysname, @code sysname, @list sysname
         Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted
         Set @cmd = 'java mirrorDb.Copy PLI UPDATE ' + @code + ' ' + @list
         EXEC master..xp_cmdshell @cmd
    CREATE TRIGGER [PLI_DELETE_TRIGGER] ON [dbo].[PLI]
    FOR DELETE
    AS
    Declare @cmd sysname, @code sysname, @list sysname
         Select @code = PLI_K_COD, @list = PLI_K_LISTINO from deleted
         Set @cmd = 'java mirrorDb.Copy PLI DELETE ' + @code + ' ' + @list
         EXEC master..xp_cmdshell @cmd
    you must go "sql server entreprise manager" right click on the table you want to add triggers and select: all activities, manage triggers.
    You have 3 examples: for an insert, for an update and for a delete
    ON [dbo].[PLI] specify the table on which you want to setup trigger.
    FOR DELETE, INSERT, UPDATE specify the event.
    The Declare statement create the variables in which I want to put some values to pass to the java program, for example which table, which event, which key fields.
    the "Select @code = PLI_K_COD, @list = PLI_K_LISTINO from inserted" set the variables with the value of the columns of the table I am interested to read from my java program, for example the variable @code receive the value of the column pli_k_kod (is the key) of the table PLI.
    The "Set @cmd = 'java mirrorDb.Copy PLI DELETE ' + @code + ' ' + @list " prepared the variable @cmd with the java command followed by the package.classname and parameters.
    The EXEC launch the command to the operating system.

  • Calling java APIs from a function module

    Hi,
    Can someone tell me whether it is possible to call Java APIs from a function module in SAP system?
    Thanks in advance,
    Vineetha

    Hi,
    I guess you have changed the properties of screen only.
    I assume you have made a Ztransaction Code.
    When you define a transaction code, you need to specify a screen number for radio option program and screen and you need to specify a screen and not subscreen.( I think so!!)
    You changed only the code without changing the transaction code properties.
    Therefore, i think u r getting a dump.
    If you want to call your subscreen, call it in some screen and then call that screen using your transaction code properties.
    To include a subscreen screen in the subscreen area of the main screen and call its PBO flow logic, use the following statement in the PBO event of the main screen:
    PROCESS BEFORE OUTPUT.
      CALL SUBSCREEN <area> INCLUDING <prog> <dynp>.
    To call the PAI flow logic of the subscreen screen, use the following statement in the PAI flow logic of the main screen:
    PROCESS AFTER INPUT.
    CALL SUBSCREEN <area>.

  • How to reference multiple instances of the same Java object from PL/SQL?

    Dear all,
    I'm experimenting with calling Java from PL/SQL.
    My simple attempts work, which is calling public static [java] methods through PL/SQL wrappers from SQL (and PL/SQL). (See my example code below).
    However it is the limitation of the public static methods that puzzels me.
    I would like to do the following:
    - from PL/SQL (in essence it needs to become a forms app) create one or more objects in the java realm
    - from PL/SQL alter properties of a java object
    - from PL/SQL call methods on a java object
    However I fail to see how I can create multiple instances of an object and reference one particular object in the java realm through public static methods.
    My current solution is the singleton pattern: of said java object I have only 1 copy, so I do not need to know a reference to it.
    I can just assume that there will only ever be 1 of said object.
    But I should be able to make more then 1 instance of an object.
    To make it more specific:
    - suppose I have the object car in the java realm
    - from PL/SQL I want to create a car in the java realm
    - from PL/SQL I need to give it license plates
    - I need to start the engine of a scpecific car
    However if I want more then 1 car then I need to be able to refrence them. How is this done?
    Somehow I need to be able to execute the following in PL/SQL:
    DECLARE
    vMyCar_Porsche CAR;
    vMyCar_Fiat CAR;
    BEGIN
    vMyCar_Porsche = new CAR();
    vMyCar_Fiat = new CAR();
    vMyCar_Porsche.setLicensePlates('FAST');
    vMyCar_Porsche.startEngine();
    vMyCar_Fiat.killEngine();
    END;
    Thanks in advance.

    You can do this by manually creating a new iterator binding in your binding tab.
    So instead of dragging the VO directly to the page, go to the binding tab, add a new executable iterator binding, and point to that one from your ELs in the page itself.

    You can achieve this using LiveCycle PDF Generator JAVA API. You can find required code here:
    Adobe LiveCycle * Quick Start (SOAP mode): Converting a Microsoft Word document to a PDF document using the Java API
    In parameters:
    //Set createPDF2 parameter values
    String adobePDFSettings = "Standard";
    String securitySettings = "No Security";
    String fileTypeSettings = "Standard OCR";
    "Standard OCR" file type setting will run OCR on input pdf. In the code, instead of doc file provide a pdf file. Resultant pdf will be searchable PDF i.e OCRed PDF.
    Feel feel to ask any further questions.

  • Calling a Remote EJBSession Facade from a Local EJBSession Facade

    Hi, I'd like to understand the way of calling a remote ejb application from a local ejbsession facade using its methods (throught data control palette) without I have to generate a Java Client. To do this, where do I put the code to get the remote ejb facade instance?.
    Thanks in advance.

    My problem is to call a application server, using rmi/jndi from a local application which has been developed using ADF+JSF+Toplink.
    Concretely, into a backing bean method I need to call a method that this available one in the facade of the other application, which resides in OAS.
    Using simple clients,it works fine, but I don't know the way to do it within backing bean, since creating a remote interface of the facade with the declaration of the remote method, it does not allow me to declare this like abstract. Nevertheless, and since already I have commented using a simple client it works to me.
    Help please.
