How to use Oracle Reports in an enterprise app, wrt file i/o?

How are people architecting their enterprise applications to make use of Oracle Reports, with respect to transmission of the output?
Do you have session beans which call the Oracle Reports JSP pages, and have them write the output to file names, the names of which you then transmit to the web layer? Alternatively, is there any practical way to "stream" the output directly from the EJB layer to the web layer and to the client?

Hello David,
When you call the report server via an URL, with DESTYPE=CACHE, the output is directly sent to the web browser.
I am not sure to well understand you question, but if you want to control the report from a session bean, you can write a bean that call report server with an URL and get the output. Today, we do not have any EJB to control Oracle Reports.
I am interested by the type of beans/architecture you would like to see in Reports, could you please send me a detailled example of a type of bean you would like to have ? ([email protected])

    Yudi,
    Wheun u installed Apps, By Deafult, Deafult reports for each product like AP, GL , AR etc. are installed.
    If u want to develop any custom report for any product like AP, GL. It means, if default reports does not serve ur requirement, then u have to develop custom report.
    To Develop Custom Report, U have to install the Devloper 6i in the Clients System.
    U can download the Developer 6i from Oracle Site and install it in the Clients system from where u want to develop

  • How to use Crystal Report in Oraacle Jdeveloper

    Hi all,

    plz  can any one help me regarding that matter
    -Amol

    Hello Amol,
    The Crystal Report for Eclipse - Java-based Crystal Reports development - is integrated into the Eclipse IDE and IBM RAD.
    However, it's not integrated with JDeveloper.
    You can still access the Crystal Java Reporting Component to create Java applications to view Crystal Reports, but you'd not be able to create RPT files unless you use Eclipse or RAD.
    More info for CR4E here:

  • How to convert Oracle reports previewer output into delimited file.

    How to convert Oracle reports previewer output into delimited file if the report has more than 1000 pages.
    I tried with previewer option File --> Generate to file --> Delimited file, but the report engine is crashing.Not generating .TXT file.
    I observed that this option is not working for more than 400 pages.
    I am using Oracle reports 6i version.
    Plz suggest me to generate .TXT file from Report previewer.

    You can specify a delimiter (a character or string of characters) to separate the data (boilerplate or field objects) in your report output in either of the following ways:
    On the command line using the DELIMITER keyword.
    In the Delimited Output dialog box or DelimitedData Output dialog box (displayed with File > Generate to File > Delimited or File > Generate to File > DelimitedData) in Reports Builder.

  • How to use Oracle partitioning with JPA @OneToOne reference?

    Hi!
    A little bit late in the project we have realized that we need to use Oracle partitioning both for performance and admin of the data. (Partitioning by range (month) and after a year we will move the oldest month of data to an archive db)
    We have an object model with an main/root entity "Trans" with @OneToMany and @OneToOne relationships.
    How do we use Oracle partitioning on the @OneToOne relationships?
    (We'd rather not change the model as we already have millions of rows in the db.)
    On the main entity "Trans" we use: partition by range (month) on a date column.
    And on all @OneToMany we use: partition by reference (as they have a primary-foreign key relationship).
    But for the @OneToOne key for the referenced object, the key is placed in the main/source object as the example below:
    @Entity
    public class Employee {
    @Id
    @Column(name="EMP_ID")
    private long id;
    @OneToOne(fetch=FetchType.LAZY)
    @JoinColumn(name="ADDRESS_ID")
    private Address address;
    EMPLOYEE (table)
    EMP_ID FIRSTNAME LASTNAME SALARY ADDRESS_ID
    1 Bob Way 50000 6
    2 Sarah Smith 60000 7
    ADDRESS (table)
    ADDRESS_ID STREET CITY PROVINCE COUNTRY P_CODE
    6 17 Bank St Ottawa ON Canada K2H7Z5
    7 22 Main St Toronto ON Canada     L5H2D5
    From the Oracle documentation: "Reference partitioning allows the partitioning of two tables related to one another by referential constraints. The partitioning key is resolved through an existing parent-child relationship, enforced by enabled and active primary key and foreign key constraints."
    How can we use "partition by reference" on @OneToOne relationsships or are there other solutions?
    Thanks for any advice.
    /Mats
