Generate entity bean from Oracle view fails

Hello,
is it possible to create an Entity Bean (v3) from an Oracle View in jDev (Build JDEVADF_11.1.1.1.0_GENERIC_090615.0017.5407)?
In the wizard I can see my view, select it, specify all the info/details about it, but when clicking 'Finish' I see the "EJB Log" window appearing empty and the entity bean is not created. Already tried it in two different PCs without success.
thanks!

You can rename EJB and EJB classes (refactor) by right-clicking on the EJB node in
project navigagor and selecting "Rename EJB and EJB Classes"
In the dialog box you would get an option to refactor classes.

  • CMP Entity Bean from dataBase views

    Hi forum,
    I Have to migrate an existing application to JEE (with EJB3).
    In this application there are a lot of dataBase views.
    I'm new in EJB3 and I don't know how to structure cleanly entity beans (Specially when it are created from dataBase views).
    My problem is that for each query made from the same dataBase view I almost have to create a new entity bean with a different @Id.
    What can I do to to avoid it?
    I had thought to genrate a new @Id (attribute not persistent) but I think is not possible. It's right ?
    Someone can help me ?
    Thanks

    "CMP provides you with database independence and less coding efforts."
    BMP is not database dependent, unless you invoke database specific things in your SQL (something I do not do). CMP on the otherhand is inherently appserver specific (which was it's goal when BEA, IBM, et al. came up with it), and still limits your design possibilities. See this thread for an example:
    http://forum.java.sun.com/thread.jsp?forum=13&thread=318785
    As for less coding effort, that is a relative statment. Yes a simple CMP bean requires less coding to develop the first time. I personally view a few lines of SQL to load and store the data as being fairly trivial. But that needs to be offset with the problems inherent in using appserver specific CMP implementations.
    As an example, try mapping WebSphere CMP to a pre-existing database without using IBM's IDE. It's an incredible pain in the ass since WebSphere does not come with a "meet-in-the-middle" solution. Any J2EE developer that has had the experience of working with different appservers (especially if they have had to port an app, as I have) can attest to the complications that arise with each implementation.
    A BMP bean, written with non-DB-specific SQL, is the most portable, most flexible approach to EntityBeans. Yes, it requires the developer to be able to write some SQL, which should not take a significant amout of time. WRT queries, you have to write them, either SQL, EQL, or some appserver specific format.
    As an aside, the use of code generators to simplify the creation of EJBs lends itself well to BMP. By using a (or writing your own) code generator, you can mitigate the annoying SQL bugs that creep up early in development.

  • CMP entity beans from tables in 9.0.3 jdev preview

    I am trying to generate CMP entity beans from oracle tables using 9.0.3 jdeveloper preview. My oracle db version is 9.2. I notice that if a table has a single column primary key, no xxxPK.java file is created. However, if the primary key is multi-column an xxxPK.java file is created. Is this correct behavior? I expected an xxxPK.java file to be created regardless of the number of columns in the primary key for the table. Has anyone else noticed this? I am new to EJB so forgive my ignorance.

    Comparing to JDev 902, I think this is a much better decision. Having to change beans with a single field PK to not using a custon PK class, to avoid using that class was a pain in JDev 902. There4s little benefit in using a custom class when there4s only a single field in it... some will say that it prevents having to do majot changes to your code if the PK changes in the future and add another field. But a careful database design will void this almost completely. So having JDev 903 use a java native class is a better option in this situation. At least from my personal point of view.

  • EJB 3.0: CMP Entity bean from view

    Hi,
    I have created an entity bean from a database view.
    I don't have a good filed to use as id in my view. So I want to generate the id in my entity bean.
    How can I do this ?
    Thanks

    Hi,
    I didn't get your question.
    CMP is something, which can be done by hand.
    So maybe it is better, to do it manually.
    Bea has some workaround, I am sure.
    Maybe it is something with deployment descriptors, which
    have to be configured to the underlying database.
    Sorry for my stupid first answer.

  • Generating an Entity Bean from a Database Table

    I am following the tutorial "How Do I: Generate an Entity Bean from a Database
    Table?" and in that process doing the "Configuring a Data Source". This is the
    message I get when I configure a data source per the tutorial and click OK. This
    data source exists and the information is correct that I have supplied.
    Do I need to put the MS jars somewhere to enable this?
    See attached file

    I've just figured it out. An input source also takes a Reader in its constructor. I was thinking that it only took an InputStream, and as the Serializer requires you to set a Writer on it, I was finding it impossible to convert between bytes and chars. Now, I have simply set a blank CharArrayWriter on the Serializer, got a char[] from it once the Serializer has written the Document to the stream, and then constructed a CharArrayReader with this char[]. It works fine now. Not that anyone read the problem anyway cos I solved it a few minutes after I posted it. Considering it first cropped up about 4 months ago and it has been niggling ever since, I am pleased!

  • Create CMP Entity Beans from Tables Wizard - Can't see any tables with DB2

    Hi,
    I'm trying to use the "Create CMP Entity Beans from Tables Wizard" to create an entity from a table in a DB2 database. The problem is, on page 2, I can't see any available tables. I have verified that the connection works (I can open the connection in the Navigator frame and I can see that table).
    Note that if I try this wizard on an Oracle database, I can see tables.
    WTF? Can someone please help?

    I second the motion. I too work in an environment with centralized data management (DBA's) that create and maintain all tables under a generic schema. This has prevented me from using the Create Entity Beans from Table feature of Jdev r3 preview.
    At least I can see that I'm not alone.
    Thanks
    When I select the "Create CMP Entity Beans from Tables Wizard," no tables or views are available to select. The JDev database connection is using an ID assigned to me.
    The tables that I am looking for were created by the DBA under his ID and are therefore in that schema. He did create Public Synonyms for them, but the tables still do not show up in the wizard.
    Is there a configuration step that I need to do to have those tables show up?
    Tables created by a DBA and then accessed by developers using a public synonym is a very common scenario and should be supported by JDeveloper (IMO).
    Thanks.
    I'm using JDev 9.0.2.8.2.

  • Howto: Iterate ADF BC from a managed bean from the View?

    Hi Everyone,
    I've been trying to iterate a BC ADF object from a managed bean from the view layer. Here is what I have done so far, but I don't seem to get any records:
    In faces-config.xml, I am passing in the BindingContext to the managed bean. (This is a session scoped bean).
    <managed-property>
          <property-name>bindings</property-name>
          <property-class>oracle.adf.model.BindingContext</property-class>
          <value>#{data}</value>
        </managed-property>In the testPageDef.xml I have the executables and bindings setup:
      <executables>
        <iterator id="TestRO1Iterator" RangeSize="-1" Binds="TestRO1"
                  DataControl="ApplicationControlDataControl"/>
      </executables>
      <bindings>
        <table id="TestRO1" IterBinding="TestRO1Iterator">
          <AttrNames>
            <Item Value="C1"/>
            <Item Value="C2"/>
          </AttrNames>
        </table>
    </bindings>In my managed bean, in addition to the accessors for the bindingContext of bindings, I have:
                 BindingContainer bc = getBindings().findBindingContainer("testPageDef");
                 ControlBinding cb = bc.getControlBinding("TestRO1");
                 RangeBinding rb = (RangeBinding)cb;
                 List testList = rb.getRangeSet();
                 Iterator testIter = testList.iterator();
                 int testCount = testList.size();
                 while (testIter.hasNext()) {
                   Map attrs = (Map)testIter.next();
                   System.out.println(attrs.get("C1")+","+attrs.get("C2"));     
                   //Do some fancy stuff here with the values.
                 }However, my testList.size() always returns 0.
    Is this the right method to programatically access the data from the view layer from a managed bean, or have I missed something completely? Are there any working samples that I could take a look at?
    Jdev: 10.1.3.1
    Thanks!
    Kenton

    Hi,
    <managed-property>
    <property-name>bindings</property-name>
    <value>#{bindings}</value>
    </managed-property>
    private BindingContainer bindings= null;
    public void setBindings(BindingContainer bc){
    bindings = bc;
    public BindingContainer getBindingContainer(){
    return bindings;
    DCIteratorBinding dciter = (DCIteratorBinding ) bc.get("TestRO1Iterator");
    RowSetIterator rsi = dciter.getRowSetIterator();
    while (rsi.hasNext()){
    Row rw = (Row) rsi.next();
    //Do some fancy stuff here with the values.
    You find several examples in the developer guide and on the Internet

  • Generated pdf file from oracle reports show bad characters

    Hello all,
    Iam fighting with a problem with generated pdf file from oracle reports which show some bad characters. I was searching for some information but it didnt help...
    I have Oracle Database 11g R2 (or 10g R2) on Oracle Linux or Windows, Oracle forms and reports 6i (i know that is very old and not supported with 11gr2 but we are in this scenario).
    NLS parameters are set like this
    server:
    NLS_CHARACTERSET EE8MSWIN1250
    NLS_TERRITORY AMERICA
    NLS_LANGUAGE AMERICAN
    client:
    NLS_CHARACTERSET EE8MSWIN1250
    NLS_TERRITORY SLOVAK
    NLS_LANGUAGE SLOVAKIA
    When I run Oracle Reports it show perfect in display and when I try to print them, they are all good with good characters, but when I try to generate pdf file, some characters like č,š,ľ are not displaying corectly... This happen only when try to generate to pdf...
    I try to work with uifont.ali on client side but without any result. Fonts for reports were installed on client and server side... Can someone help me with this problem? Thank you very much for every advice.
    Martin

    Hi Sergiusz,
    Thank you for your reply. I look at what you wrote and try to make some test...
    1) For first I download FontForge, which can generate type1 font from true type. So I open FontForge and open my Arial.ttf font and use "Generate Fonts" to save my Arial.ttf font to pfb and pfm (whoch are need to set in uifont.ali). I have to change encoding, because my font has 2byte encoding so I reecondode the font from ISO10646-1 to ISO8859-2 and generate to pfb.
    2) Then I navigate REPORTS_PATH from regedit to my *.pfm and *.pfb files.
    3) I add these lines to end of my uifont.ali
    [ PDF:Embed ]
    Arial = "Arial.pfm Arial.pfb"
    ArialNarrow = "ArialNarrow.pfm ArialNarrow.pfb"
    4) Then I generate my report but nothing change... I check "Font used" in my pdf file, but there were not my fonts embedded I guess..
    I also try PDF:Subset, but it doesnt change anything... I try PDF aliasing to see if my uifont is working - this work very well, but I dont need to change font...
    Any other advice? Thank you so much to everyone!

  • Java bean from oracle Forms6i

    Hi Guys,
    I am calling java bean from oracle Forms6i (implementation
    class property set to bean class). This java bean in turn
    calling some JNI methods written in C. The application server
    (Forms6i) is hanging at the point of calling the JNI method.
    Is oracle Forms6i supports all java functionality (JNI here)
    and if so how to solve the problem ?
    Any pointers or tips in this regard is highly appreciated ?
    Thanks & Regards

    To call Java from forms:
    look at the technical documents on Java integration at
    http://otn.oracle.com/products/forms
    and also look at the Javabeans and PJC samples in the sample
    code section of Forms on OTN.
    Creating a random number using a java class is an excelent
    example of how to use Java with forms.

  • CMP Entity Beans in Oracle 9iAS

    Hi!
    I've deployed entity beans into Oracle 9iAS, but keep getting the following error each time I try to lookup the bean:
    "javax.naming.NamingException: Unknown reasons [Root exception is org.omg.CORBA.UNKNOWN: minor code: 16 completed: Maybe]"
    The JNDI name of the bean are ok and I'm calling it correctly. I'm calling my a Session Bean in a similar way and it works fine.
    I'm using JDevloper 3.2.3 to deploy the beans and OAS version is 1.0.2.2.
    Thanks for any advices,

    gday -
    OC4J implements major portion of the EJB 2.0 PFD1 specification.
    It supports the new container contract and persistence model in PFD1, along with associated new XML DD tags, so yes, it does support abstract implementation EJB classes and abstract accessors definitions.
    It does not support the latest EJB 2.0 PFD2 modifications and also does not support the local/remote interface model, EJB-QL, home methods, etc.
    cheers!
