Design Suggestion for Custom ADF Application

Hi
I have a custom database table.
I have a custom database view which has query from multiple tables including the above table.
The custom table in the view is joined with other tables by columns like inventory_item_id, organization_id etc.
I have to show user a screen where the results of this view are shown in a table.
The user should be able to enter some data in the screen for these rows.
(he will be able to enter the data only for fields from my custom table)
When he press save button, we should enter the new data given by user into the custom table
along with some other values from view rows .. like inventory_item_id, organization_id etc ..
Can you suggest a best approach to achieve this ?
I have to use BC4J for Model and ADF For UI.
As far as my knowledge goes, I think we will not be able to do this with an updateable view since we might hit the error
ORA-01779: cannot modify a column which maps to a non key-preserved table
Is there a design pattern we can follow in BC4J so that this can be achieved?
Thanks for any help.

Any view can be made updatable if you write INSTEAD OF triggers for it. That might be a good solution for you. You can also base a View Object on more than one Entity Object, and as long as there are good associations between the EOs it ought to work fine.

  • Design approach for custom Fiori application

    Dear Experts,
    Good day to all...!
    I am having a query on finalizing design approach for one of my custom Fiori Application development  using SAP UI5.
    Current Application design and  Features:
    As now we are having application, which is been used in laptops. The application structure is like (SAP R3 --> SUP -->UI (using .net) [back-end à Middlewareà UI).
    The UI is hosted on IIS server and the application type is desktop, so the users can use the application in offline as well.
    Once its connected to internet, they push all the data back to SAP via SUP.
    Proposal :
    We are planning to migrate the same application into Fiori with same offline features and extending to mobiles and devices.
    I have few queries here.
    What will be the best approach to deploy the application either SUP(Latest version of SMP) or SAP R3.
    If SAP R3 to deploy App:
    If we choose to deploy the application in R3, How to support the offline usage mobile and devices.
    Will the HTML5 local storage or indexed DB’s are sufficient to support the offline usage.
    In this case, Shall we drop the SUP/SMP, Since the application directly accessed from SAP R3 ..?
    SUP/SMP to deploy the app:
    In this case, I need to create (wrap the ui5 files into hybrid application) a hybrid application to support the mobile and devises as native application..? Correct me If I am wrong..:)
    Hope I can use the SUP/SMP local storage options to support my offline usage..? Correct me If I am wrong..:)
    What will be the best option to support desktop offline  usage.
    We are yet to take a decision on this.. Please provide your valuable inputs , which will help us to take some decisions.
    Thanks & Regards

    Hi Anusha,
    considering the reusability aspect the components approach is the much better one (see also the best practices dev guide chapter regarding components SAPUI5 SDK - Demo Kit).
    It allows you to reuse that component in different applications or other UI components.
    I also think that the Application.js approch will not work with Fiori, cause the Fiori Launchpad loads the Components.js of the Fiori app in an Component Container.

    Hi,
    since you implements the backing bean from PagePhaseListener. some where the same view is excuting before getting the selected record. Even if you select the record after excuteQuery() it will set the first record as selected. Please try to check some where query is excuting.
    try give some more details like what are all the methods you are using in PagePhaseListener and where you worte u r coding.

  • Custom ADF Application with Process Instance Details Task Flow

    Hi,
    I want to use Process Instance Details Task Flow which is referred to in the doc below.
    http://download.oracle.com/docs/cd/E21764_01/user.1111/e15175/bpmug_ws_taskflows.htm#BACDBDJA
    But I could not find the task flow in the JAR files nor in the libraries described in the doc (Actually I could not find one of the JARs itself, adflibWorkspaceTaskFlows.jar).
    Does anyone know where can I find it and how to use it?
    It is more convenient if I can create a custom ADF application which contains information on process instance details using Java API for BPM.
    So I'd like to also ask whether such API is available or not.
    Regards,
    Kenji

    I also can't find the adflibWorkspaceTaskFlows.jar from the specified directory in the [ BPM Users Guide|http://download.oracle.com/docs/cd/E17904_01/user.1111/e15175/bpmug_ws_taskflows.htm#BACBBDCE] : "$FMW_HOME/AS11gR1SOA/soa/modules/oracle.soa.worklist_11.1.1"
    When I tinker the OracleBPMWorkspace.ear from the $SOA_HOME\soa\applications, it has the OracleBPMWorkspace.war that contains the adflibWorkspaceTaskFlows.jar in its WEB-INF\lib directory, but the adflibWorkspaceTaskFlows.jar does not contain the "processApplicationsTaskflow.xml" or the "processInstancesTaskflow.xml". Those task flows were present in the WEB-INF itself of the OracleBPMWorkspace.war itself which is not deployed as an ADF library.
    Please advice,

  • Suggestions for Oracle ADF learners

    Hi ADF experts,
    Some one suggest,For Oracle ADF learners must having java knowledge ?
    I am new to JAVA & ADF. But I want to learn Oracle ADF. Is java skills must to learn Oracle ADF.
    I am Oracle BPM11g developer.So for Oracle BPM11g,Oracle ADF is front end for user interaction.
    Guide me.
    Best Regards,
    KasiRaju.

    Core Java should be enough to begin with. If you know the concepts of any OOPS programming language (C/C++), Learning Core Java should be very easy.
    ADF is nothing but Oracles version of JSF (Java Server Faces) with UI components. My Point here is, it is Java that sits at the base of ADF. Hence, I would say u Must have Java knowledge to develop a REAL useful page/application.

  • Usage of SAP Event Management as backend for custom mobile applications

    Hi,
    I'm am looking for an appropriate implementation approach for custom mobile applications as complement for warehouse processes with SAP Extended Warehouse Management.
    Possible scenarios:
    i) Goods issue - loading process
    There are requirements like capturing of various data about the vehicle and load per RF handheld computer. The goal is to trace and archive them for analysis and reporting purposes.
    ii) Goods receipt -production process
    The production supply and goods receipt from production are realized in SAP EWM. The request is to collect data about the production process for quality reasons by use of RF devices.
    You can picture oneself the additional mobile data entry activities during the various processes as predefined question catalogues with answer options.
    The frontend - the additional mobile transactions can be realized with the EWM-Radio-Frequency-Framework, too. But I feel confindent that there is a better way to track, trace, store, analyse, report and archiv of the collected data to Y-TABLES.
    Would you recommend to use SAP Event Management for this purpose to complement the SAP EWM processes?
    The existing requirements as described above is in my understanding only a little fraction of the capabilities of SAP Event Management. The data collection and evaluation process is local within the warehouse. At first there is not requested any automatic system behaviour to particular events...
    There are a lot material and information about SAP Event Management. But I havent found an easy getting started for my simple business scenario to enhance the EWM processes with the EM capabilities. How I could realize a question/anwer catalogue with the EM tools?
    Thanks in advance!
    Best regards,
    Laura

    Hello Laura,
    principally the process would fit for EM. But EWM is not integrated up to now to EM i.e. you would have to do the connection from EWM to EM by your own.
    How to generally connect an application to EM is described here:
    service.sap.com/scm
    -> Event Managament
    -> Technical Information
    -> Connect SAP objects to SAP EM

  • Design Suggestions for Multiple DaqMX Task Streaming App?

    I'm working on a LabVIEW application in which I'm streaming high-speed data to disk from multiple PXI devices simultaneously.  Each device has its own DaqMX task, and all tasks stream to the same file.  The PXI device configuration (which devices are in the chassis, which slots they're in, and which channels to read from each device) is determined at runtime.
    Does anyone have a suggestion for a design model for this?  To make matters worse, I'd like to be able to specify a channel to monitor its data during the streaming.  I'm thinking the Producer-Consumer model is the basic approach, and I'm at the point where I have an array of DaqMX tasks, one for each device.  I could probably extend that array to be an array of clusters containing:
       1) DAQ Command (e.g. Initialize, Start, Stop, Acquire, etc)
       1) Task ID
       2) Control reference to 2-D array (where each DaqMX read can be stored)
       3) Array of channel names (to allow selection of channel to be monitored
    This could be passed as notifier data, to a data collection subVI, but the part I'm struggling with is finding the best way to run X number of tasks in parallel, where X is not known until runtime.
    Any suggestions would be appreciated.

    Thanks for the input.  With regards to the file format, the decision has been made by my superiors not to use TDMS - unfortunate, but NI hasn't provided the information to write a MatLab file reader, which is a requirement.  So, I've created a custom file format tailored to the needs of my application, but generic enough to be used for other apps. With it, I've been able to stream 8 channels at 800KHz (4 channels each from 2 PXI-6120s) without breaking a sweat.  However, the performance varies greatly depending on which slots the cards are in (but that's a whole different discussion - see the PXI forum for that one).  Once NI solves that one, I'll feel a lot more comfortable.
    I have already made reentrant subVIs that can perform a specific DAQ task.  The problem with a for loop is that the VI sits and wait for a start trigger, then acquires the streaming data.  I can't start the next VI because I'm in the first one.  I thought about creating a data collection VI, and this VI would start up to 6 other VIs in parallel, based on how many and which cards were present.  It's a bit messy, because each slot can contain one of two devices, so I'd need to check which type it was before calling it.  I'm thinking I'll have to create the task list and the references to the data in the main GUI loop, and then pass this using a notifier or queue to the data collection loop. 

  • Adobe Create Suite 4 Design Premium for Windows Lost Application disk #2

    Hi, I have the Adobe Create Suite 4 Design Premium for Windows and have lost the Application disk #2 and cannot reinstall this on my new laptop.  I have the licenses and the rest of the disks.  I have called Adobe and they no longer support CS4.  They suggested I try to find someone who has the software and get a copy of disk 2

    I'm not seeing anything but individual applications (and it looks like updates, not installers) in the public forders.
    You should be able to get the trial by going to Download Adobe CS4 and CS3 Free Trials Here (incl. After Effects) | ProDesignTools and following the directions VERY CAREFULLY. There is no differnce between trial and licensed installers, so you can enter your serial number when asked.

  • Database design problem for multiple language application

    Hi All,
    We are working on a travelling portal and for a traveling portal its content and details are the heart.we are planning to have it in multiple locale so this means we need to handle the dynamic data for each locale.
    currently we have following tables
    Destination
    Transport
    Places of Interests
    user comments etc.
    each table contains a lot of fields like
    Name
    ShortDescription
    LongDescription
    and many other fields which can contains a lot of data and we need to handle data in locale specific way.
    i am not sure how best we can design an application to handle this case,one thing came to my mind is like putting extra column for each locale in each table but that means for a new locale things needs to be changed from database to code level and that is not good at all.
    Since each table contains a lot of columns which can contain data eligible for internationalization so my question is what might be the best way to handle this case
    After doing some analysis and some goggling one approach that came to my mind is as below..
    i am planning to create a translation table for each table,like for destination i have the following design
    table languages
    -- uuid (varchar)
    -- language_id(varchar)
    -- name (varchar)
    table Destination
    --uuid (varchar)
    other fields which are not part of internationalization.
    table Destination_translation
    -- id (int)
    -- destination_id (int)
    -- language_id (int)
    -- name (text)
    -- description(text)
    Any valuable suggestion for above mentioned approach are most welcome...

    This approach sounds reasonable - it is the same approach used by Oracle Applications (Oracle ERP software). It de-normalizes information into two tables for every key object - one contains information that is not language sensitive and the other contains information that is language sensitive. The two tables are joined by a common internal id. Views are then created for each language that join these tables based on the common id and the language id column in the second table.

    Regards,
    Nagaraju .D

    Nagaraju,
    You can configure the application to use a different security mechanism other than jazn-data.xml (known as the file-based provider). Using something like LDAP or a custom JAAS provider would enable you to do what you want.
    The security documentation for OC4J is [url http://download.oracle.com/docs/cd/E12524_01/web.1013/e12514/toc.htm]here

  • Advice using workspace in custom ADF application

    Submitted on behalf of Mike Rooney (who cannot access this forum):
    We are analyzing Oracle BPM 11g beta and would like to understand existing resources for building worklist views, task status, bpm reports, etc, into our custom ADF 11g application. We want to create components on our ADF application pages that mimic these features provided by Oracle Workspace. Are there APIs, libraries or rich components that exist? We have reviewed Chapter 29 of the Oracle SOA 11g Developer Guide which discusses a programmatic solution for building a custom worklist client. We are wondering if there are any alternative rich components or declarative solutions for this functionality.
    Any help or advice is appreciated!
    -- Becky Kellinger

    Sorry for the delay on this one.
    Our 11g api is completely backward compatible with 10g. So the source we provide for the JSP based worklist app in 10g still works with 11g.
    Starting with BPM PS1, we are also providing reusable taskflows for customers to create their own ADF app and reuse our worklist regions in that app.

    Hi,
    I am developing an ADF application where the users do not want to use the mouse. So I would like to know if there are a best practice for this?
    Well HTML (and this is the user interface you see) follows a tab index navigation that you follow with "tab" and "shift+tab". Anything else is a short cut for which you use mnemonics (as you already do) or shortcuts (explained in http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html). There is a distinction to make between non-web environments (which I think you and your users have abackground in) and client desktop environments. Browsers block some keyboard functionality for their own purpose. So you may have to find a list of keys first that work across browsers. Unlike desktop clients, which allow you to "press a button" without the button to take focus, this cannot be done on the web. So you need to be clever here, avoiding buttons at all.
    The following paper is about JavaScript in ADF and explains the basics for what Chris Muir explains in : http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
    http://www.oracle.com/technetwork/developer-tools/jdev/1-2011-javascript-302460.pdf
    It has the outline for how to register short cut keys that perform a specific action (e.g. register ctrl+d to delete the current row you are on, or press F11 to execute a query (similar to Oracle Forms frmres files)). However, be aware that this includes some code you have to write (actually quite some code to be honest).
    http://www.oracle.com/technetwork/developer-tools/adf/learnmore/79-global-template-button-strategy-360139.pdf (are there an example implementation?), or
    http://one-size-doesnt-fit-all.blogspot.dk/2010/11/adf-ui-shell-supporting-global-hotkeys.html
    Actually these are implementations as they come with example code for you to use and customize, do they? So what is this question asking for more ? Also note that global buttons don't quite have anything in common with the question you asked. I assume you want to see it as an implementation of the Forms toolbar that operates on the form or table the focus is in. This however does not work for the web as there is nothing that keeps track of which component has a focus and to what iterator (data block) it belongs. This would involve even more coding (though possibly doable)
