What is the BEST practice - use BO or Java Object in process as webservice

Hi All,
I have my BP published as web service. I have defined My process input & output as BOs. My BP talks to DB through DAO layer(written in JAVA) which has Java objects. So I have BO as well as java Objects. Since I am collecting user input in BO, I have to assign individual values contained in BO to Java object's fields.
I want to reduce this extra headache & want to use either of BO or Java object.I want to know What is the best practice - use BO or Java object as process input. If it is BO,how I can reuse BOs in Java?
Thanks in advance.
Thanks,
Sujata P. Galinde

Hi Mark,
Thanks for your response. I also wanted to use java object only. When I use java object as process input argument..it is fine. But when I try to create Process web service, I am getting compilation error - "data type not supported".....
To get rid of this error, I tried to use heir (BO inheriting from java class). But while invoking process as web service, it is not asking for fields that are inherited from java class.
Then I created Business Object with a field of type java class... This also is not working. While sending request, it is giving an error that - field type for fields from java class not found.
Conclusion - not able to use java object as process(exposed as web service) input argument .
What is the Best & feasible way to accomplist the task - Process using DAO in Java & exposed as web service.
Thanks & Regards,
Sujata

  • What is the best practice for using the Calendar control with the Dispatcher?

    It seems as if the Dispatcher is restricting access to the Query Builder (/bin/querybuilder.json) as a best practice regarding security.  However, the Calendar relies on this endpoint to build the events for the calendar.  On Author / Publish this works fine but once we place the Dispatcher in front, the Calendar no longer works.  We've noticed the same behavior on the Geometrixx site.

  • What is the best practice to perform DB Backup on Sun Cluster using OSB

    I have a query on OSB 10.4.
    I want to configure OSB 10.4 on 2 Node Sun Cluster where the oracle database is running.
    When im performing DB backup, my DB backup job should not get failed if my node1 fails. What is the best practice to achieve this?

    Hi,
    Each Host that participates in an OSB administrative domain must also have some pre-configured way to resolve a host name to an IP address.Use DNS, NIS etc to do this.
    Specify cluster IP in OSB, so that OSB always looks for Cluster IP only instead of physical IPs of each node.
    Explanation :
    If it is 2-Node OR 4-Node, when Cluster software installed in these nodes we have to configure Cluster IP so that when one node fails Cluster IP will automatically move to the another node.
    This cluster IP we have to specify whether it is RMAN backup or Application JDBC connection. Failing to second node/another Node is the job of Cluster IP. So wherever we install cluster configuration we have to specify in all the failover places specify CLUSTER IP.
    Hope it helps..
    Thanks

    What are the best practices to migrate VPN users for Inter forest mgration?

    It depends on a various factors. There is no "generic" solution or best practice recommendation. Which migration tool are you planning to use?
    Quest (QMM) has a VPN migration solution/tool.
    ADMT - you can develop your own service based solution if required. I believe it was mentioned in my blog post.

  • What is the best practice for changing view states?

    I have a component with two Pie Charts that display
    percentages at two specific dates (think start and end values).
    But, I have three views: Start Value only, End Value only, or show
    Both. I am using a ToggleButtonBar to control the display. What is
    the best practice for changing this kind of view state? Right now
    (since this code was inherited), the view states are changed in an
    ActionScript function which sets the visible and includeInLayout
    properties on each Pie Chart based on the selectedIndex of the
    ToggleButtonBar, but, this just doesn't seem like the best way to
    do this - not very dynamic. I'd like to be able to change the state
    based on the name of the selectedItem, in case the order of the
    ToggleButtons changes, and since I am storing the name of the
    selectedItem for future reference.
    Would using States be better? If so, what would be the best
    way to implement this?
    Thanks.

    I would stick with non-states, as I have always heard that
    states are more for smaller components that need to change under
    certain conditions, like a login screen that changes if the user
    needs to register.
    That said, if the UI of what you are dealing with is not
    overly complex, and if it will not become overly complex, maybe
    states is the way to go.
    Looking at your code, I don't think you'll save much in terms
    of lines of code.

  • What is the best practice in securing deployed source files

    hi guys,
    Just yesterday, I developed a simple image cropper using ajax
    and flash. After compiling the package, I notice the
    package/installer delivers the same exact source files as in
    developed to the installed folder.
    This doesnt concern me much at first, but coming to think of
    it. This question keeps coming out of my head.
    "What is the best practice in securing deployed source
    files?"
    How do we secure application installed source files from
    being tampered. Especially, when it comes to tampering of the
    source files after it's been installed. E.g. modifying spraydata.js
    files for example can be done easily with an editor.

    Hi,
    You could compute a SHA or MD5 hash of your source files on
    first run and save these hashes to EncryptedLocalStore.
    On startup, recompute and verify. (This, of course, fails to
    address when the main app's swf / swc / html itself is
    decompiled)

  • What is the best practice for inserting (unique) rows into a table containing key columns constraint where source may contain duplicate (already existing) rows?

    My final data table contains a two key columns unique key constraint.  I insert data into this table from a daily capture table (which also contains the two columns that make up the key in the final data table but are not constrained
    (not unique) in the daily capture table).  I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns).  Currently, what I do is to select * into a #temp table from the join
    of daily capture and final data tables on these two key columns.  Then I delete the rows in the daily capture table which match the #temp table.  Then I insert the remaining rows from daily capture into the final data table. 
    Would it be possible to simplify this process by using an Instead Of trigger in the final table and just insert directly from the daily capture table?  How would this look?
    What is the best practice for inserting unique (new) rows and ignoring duplicate rows (rows that already exist in both the daily capture and final data tables) in my particular operation?
    Rich P

    Please follow basic Netiquette and post the DDL we need to answer this. Follow industry and ANSI/ISO standards in your data. You should follow ISO-11179 rules for naming data elements. You should follow ISO-8601 rules for displaying temporal data. We need
    to know the data types, keys and constraints on the table. Avoid dialect in favor of ANSI/ISO Standard SQL. And you need to read and download the PDF for: 
    https://www.simple-talk.com/books/sql-books/119-sql-code-smells/
    >> My final data table contains a two key columns unique key constraint. [unh? one two-column key or two one column keys? Sure wish you posted DDL] I insert data into this table from a daily capture table (which also contains the two columns that make
    up the key in the final data table but are not constrained (not unique) in the daily capture table). <<
    Then the "capture table" is not a table at all! Remember the fist day of your RDBMS class? A table has to have a key.  You need to fix this error. What ETL tool do you use? 
    >> I don't want to insert rows from daily capture which already exists in final data table (based on the two key columns). <<
    MERGE statement; Google it. And do not use temp tables.

  • What is the best practice to display info of completed task in process flow

    Hi all,
    I'm starting to study BPM modeling with CE7.1 EHP1. Thanks to the tutorial and example on SDN site and I can easily build my own process in NWDS and deploy to server, start it, finish it.
    I like the new runtime which can show a BPMN diagram to the processors. However, I can't find a way to let the follow up processor to review the task result completed in previous step. I'm more familiar with Guided Procedure, and know there is "Display Callable Object" which can used to show some info of a completed task when the processor/owner/admin/overseer click on a completed task.  Where is the feature in BPM ? What is the best practice to show such task information in BPM environment.
    For example, A multiple level approval process, the higher level approver need to know the comment written by the previous approver. Can he read this information from process flow ?
    I think it is very important feature for a BPM platform. In Guided Procedure, such requirement can be done with Display Callable Object + View Permission, and you just need some coding for the UI. If BPM is superior to GP, I think there must be a way to achieve this, I just do not know how ?
    Can anyone shed me some light on it ?

    Oliver,
    Thanks for your quick reply.
    Yes, Notes and Attachment CAN BE USED for the purpose. But I'm still looking for a more elegant solution.
    With the solution of using Notes/Attachment, the processor need to give input at two places : the task UI and Note/Attach , with similar or same data. It is really annoying.
    Is there any SAP BPM real-world deployment ? None of customer has the requirement ?

  • What is the best practice for full browser video to achieve the highest quality?

    I'd like to get your thoughts on the best way to deliver full-browser (scale to the size of the browser window) video. I'm skilled in the creation of the content but learning to make the most out of Flash CS5 and would love to hear what you would suggest.
    Most of the tutorials I can find on full browser/scalable video are for earlier versions of Flash; what is the best practice today? Best resolution/format for the video?
    If there is an Adobe guide to this I'm happy to eat humble pie if someone can redirect me to it; I'm using CS5 Production Premium.
    I like the full screen video effect they have on the "Sounds of pertussis" web-site; this is exactly what I'm trying to create but I'm not sure what is the best way to approach it - any hints/tips you can offer would be great?
    Thanks in advance!

    Use the little squares over your video to mask the quality. Sounds of Pertussis is not full screen video, but rather full stage. Which is easier to work with since all the controls and other assets stay on screen. You set up your html file to allow full screen. Then bring in your video (netstream or flvPlayback component) and scale that to the full size of your stage  (since in this case it's basically the background) . I made a quickie demo here. (The video is from a cheapo SD consumer camera, so pretty poor quality to start.)
    In AS3 is would look something like
    import flash.display.Loader;
    import flash.net.URLRequest;
    import flash.display.Bitmap;
    import flash.display.BitmapData;
    import flash.ui.Mouse;
    import flash.events.Event;
    import flash.events.MouseEvent;
    import flash.display.StageDisplayState;
    stage.align = StageAlign.TOP_LEFT;
    stage.scaleMode = StageScaleMode.NO_SCALE;
    // determine current stage size
    var sw:int = int(stage.stageWidth);
    var sh:int = int(stage.stageHeight);
    // load video
    var nc:NetConnection = new NetConnection();
    nc.connect(null);
    var ns:NetStream = new NetStream(nc);
    var vid:Video = new Video(656, 480); // size off video
    this.addChildAt(vid, 0);
    vid.attachNetStream(ns);
    //path to your video_file
    ns.play("content/GS.f4v"); 
    var netClient:Object = new Object();
    ns.client = netClient;
    // add listener for resizing of the stage so we can scale our assets
    stage.addEventListener(Event.RESIZE, resizeHandler);
    stage.dispatchEvent(new Event(Event.RESIZE));
    function resizeHandler(e:Event = null):void
    // determine current stage size
        var sw:int = stage.stageWidth;
        var sh:int = stage.stageHeight;
    // scale video size depending on stage size
        vid.width = sw;
        vid.height = sh;
    // Don't scale video smaller than certain size
        if (vid.height < 480)
        vid.height = 480;
        if (vid.width < 656)
        vid.width = 656;
    // choose the smaller scale property (x or y) and match the other to it so the size is proportional;
        (vid.scaleX > vid.scaleY) ? vid.scaleY = vid.scaleX : vid.scaleX = vid.scaleY;
    // add event listener for full screen button
    fullScreenStage_mc.buttonMode = true;
    fullScreenStage_mc.mouseChildren = false;
    fullScreenStage_mc.addEventListener(MouseEvent.CLICK, goFullStage, false, 0, true);
    function goFullStage(event:MouseEvent):void
        //vid.fullScreenTakeOver = false; // keeps flvPlayer component from becoming full screen if you use it instead  
        if (stage.displayState == StageDisplayState.NORMAL)
            stage.displayState=StageDisplayState.FULL_SCREEN;
        else
            stage.displayState=StageDisplayState.NORMAL;

  • What are the best practice in report design ?

    Hi,
    According to you, what are the best practices in report desing about layout, fonts and colors ?
    Thks

    Hi,
    It all depends that what type of report you are designing and what tool you are using - WebI or Crystal.
    And in WebI, if it is cross tab or Tabular report etc.
    One most important thing is that what is client requirement. May be client does not like which is best practice.
    On the base of my personal experience I will create few demo reports using different options - layout, colors and fonts and show them to client so that they may decide.

  • What is the best practice for creating primary key on fact table?

    what is the best practice for primary key on fact table?
    1. Using composite key
    2. Create a surrogate key
    3. No primary key
    In document, i can only find "From a modeling standpoint, the primary key of the fact table is usually a composite key that is made up of all of its foreign keys."
    http://download.oracle.com/docs/cd/E11882_01/server.112/e16579/logical.htm#i1006423
    I also found a relevant thread states that primary key on fact table is necessary.
    Primary Key on Fact Table.
    But, if no business requires the uniqueness of the records and there is no materilized view, do we still need primary key? is there any other bad affect if there is no primary key on fact table? and any benifits from not creating primary key?

    Well, natural combination of dimensions connected to the fact would be a natural primary key and it would be composite.
    Having an artificial PK might simplify things a bit.
    Having no PK leads to a major mess. Fact should represent a business transaction, or some general event. If you're loading data you want to be able to identify the records that are processed. Also without PK if you forget to make an unique key the access to this fact table will be slow. Plus, having no PK will mean that if you want to used different tools, like Data Modeller in Jbuilder or OWB insert / update functionality it won't function, since there's no PK. Defining a PK for every table is a good practice. Not defining PK is asking for a load of problems, from performance to functionality and data quality.

  • What are the best practices to create surrounding borders?

    Good day everyone,
    I was wondering what is the best practices to create a look in my iOS app like the one below? How are they accomplishing the creation of the borders, is there a tool in Xcode IB to do that?
    Thank you in advance

    Once again thanks for your input, however I am still not clear how you have accomplish the rounded corners, you do not mention that in your reply.
    I did some research on my end and I was able to accomplish what I want with a UIView using the code below in an outlet:
    redView.layer.cornerRadius = 10;
    redView.layer.borderColor = [UIColor greenColor].CGColor;
    redView.layer.borderWidth = 5;
    However, I cannot do the same for the UITableView or UITableView cell.
    Thanks

  • What are the best practice to design Dashboard?

    Hi Friends,
    What are the best practice to design Dashboard?
    Thanks

    1) Use section name instead of Title View to name your report. This way sections can be collapsed and user can still see report name.
    2) Enable alternate coloring in tables and pivots for easy readablity and set table and pivot widths to 100% (for reports in dashboards) to reduce white space and achieve a more "professional look."
    3) Use column selectors and view selectors to reduce the width of reports and reduce the amount of columns user sees to a "practical minimum."

  • What are the best practices for generating an EPS logo from InDesign?

    Our costomer is running into technical issues with the logo we sent them, which was exported from Indesign. Images were not embedded and fonts missing. I was able to embed the images and fonts. However, we DO NOT want them to be able to make any text changes. So after exporting an eps, I opened the file in Adobe Illustrator and made all the text outlines. I hope this works. But I just wanted to post the question on what are the best practices for doing this?
    The client needs the logo with transparent background, images emebdded and type in outlines. Also, they need some space around the text. When I exported the eps, the file is right up on the edge of the type.

    It sounds like you are pretty far from "best practice" with regard to logo design and delivery.
    These days, the very use of the EPS format should be considered bad practice, and some other terms in your post, (i.e., 'images,' 'missing fonts'), make it sound like there is not a seasoned logo designer involved.
    That said, you probably already got the advice you need to get out of the immediate jam. However, without proper logo design, you and the client will soon be facing other problems. You should be delivering a 100% vector graphic in single-color (black) and corporate-color(s) versions, with no live font data, that has been test-scaled to very small and very large sizes; ensuring it will work at postage-stamp size and on the side of a truck or building, with specific spot color(s) and proportions that will enable it to be offset printed, embroidered and screen-printed on apparel, and cut into signage materials and decals.
