Java Bean In Forms6i

Hi,
Can a java bean be called from a form executing in Client server environment.
If yes how can it b achieved?
Thanks & Regards,
Abhijeet

Not if you need to use any graphical component of it. For this you'll need to run on the Web.
If you just want to invoke the logic of the bean try using the Java importer.

  • How to attach a java bean in forms6i

    Hi,
    I am new to oracle forms6i. i just want to ask on how to attach a java bean to forms6i.i did putting the full directory path to the implementation class but it has an error, bean not found. what should i do?
    Your help is highly appreciated.

    The implementation class should contain the package and class name of the bean e.g. com.groundside.beans.DateFieldBean, not a directory location. The bean itself is loaded from the JAR files specified to be downloaded with the applet.
    If you are running client server then you can't use JavaBeans this way - it's a web only feature.

  • Deploying Customised Java Beans on Forms6i

    I m creating my own custormised Java Bean and wanan deploy in Forms6i ..by either using BeanArea or chaning the property of the Forms Item only ....but i m not able to do that .can u help me tellnig what all requirements are for that and also more about IView interface as i m not able to fine any help for that ....

    Gilbert, Have a lookat the FileUpload sample PJC on the Forms Demo page on OTN. This already does what you want. It has the source code so you can see how it works.

  • 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
    Chandra Mohan

    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.

  • What is the difference between java direct or java bean in JSP?

    What is the difference if I use java code directly in JSP or use java bean in JSP?
    Which class to use for receiving the passed parameter from html or java script? Any difference for java code and java bean in the way receiving the passed data?
    How can I pass string from jsp to html or java script?

    it's generally accepted as better design to separate presentation from logic. meaning, the java code in the jsp should be used to support displaying data, as oppsoed to implementing the application - like database access, etc.
    when the logic is separated from the presentation, it allows you to reuse logic components within several jsp pages.
    if you decide to change the presentation layer in the future (to support wap, for example) you don't need to rewrite your entire application, since the "guts" of the application is outside of the jsps.
    it is also a good idea to separate your business logic from your data layer. adding a "buffer zone" between these layers helps in the same manner as in separating presentation from logic. if you're using flat files for storage now, upgrading to a database wouldn't require rewriting all your business logic, just the methods which write out the data to a file, for example.
    once you feel comfortable with separating the various layers, check out the struts framework at http://jakarta.apache.org/
    to answer your second question, to get parameters passed in from HTML forms, use ServletRequet's getParameter() method.
    in tomcat:
    <% String lastName = request.getParameter( "lastname" ); %>
    to answer your third question: when displaying the HTML from withing a jsp, print out the string to a javascript variable or a hidden form element:
    <% String firstName = "mike"; %>
    <input type="hidden" name="firstname" value="<%= firstName %>">
    <script language="javascript1.2">
    var firstName = "<%= firstName %>";
    </script>
    this jsp results in the following html:
    <input type="hidden" name="firstname" value="mike">
    <script language="javascript1.2">
    var firstName = "mike";
    </script>

  • Java Bean Connectivity and Closing Connections (XI 3.0)

    Hi guys,
    We have existing Java Beans that we would like to use with Crystal Reports. Our current Java beans return a disconnected GridModel and explicitly close the connection immediately after so that they can be returned to the connection pool (Oracle).
    Once we modified these beans to return ResultSets we found that closing the connection also closes all the associated ResultSets and Statements.
    What is the best practice here?
    Modify the Java bean to close the connection in the finally block?
    Will Crystal clean up after itself?
    I also see there is something called a CachedRowSet which is disconnected:
    http://java.sun.com/j2se/1.5.0/docs/api/javax/sql/rowset/CachedRowSet.html
    Is this supported by Crystal?
    Thanks,
    Kevin D Lee =)

    Hello Kevin,
    Enterprise XI 3.0 CRConfig.xml points to Java JRE 1.5 provided with the install, so you should be ok with the CachedRowSet. 
    It's used by other customers for disconnected operation.
    Since you're going to Oracle, you'd likely encounter issues mapping Oracle fields to POJO property types.
    Furthermore, POJO Factory libraries that were shipped with Crystal Reports XI Release 2 aren't shipped with Enterprise XI 3.0, so you'd not find that an out-of-the-box option. 
    Another alternative to CachedRowSet is to define callback method in your JavaBeans class that Crystal will call when it's done with the data source. 
    This has been implemented in XI 3.0 (track ADAPT00877915) - excerpt from the track note:
    <JavaBeans>
        <CacheRowSetSize>100</CacheRowSetSize>
         <JavaBeansClassPath>c:\javabeans\</JavaBeansClassPath>
         <CallBackFunction>CrystalReportsLogoff</CallBackFunction>
    </JavaBeans>
          Customer can configuration the <CallBackFunction/> to let CR know
          which function should be invoked when loging off.
    Advantage of CachedRowSet is that you can immediately close it after you've read all the data, disadvantage would be the default implementation stores all data in memory.
    Advantage of the callback method is that it would use the JavaBean you've supplied (and not load all data immediately in memory), but callback won't be called immediately, but only after the report is done with.
    Sincerely,
    Ted Ueda

              You realy can do it like Xiang says, but the better way is to use packages. That's
              the way BEA is designed for. If you use packages you can but your bean classes
              in every subfolder beneath Classes. Here for example we have the subfolders test
              and beans:
              You have to declare the package on top of your Bean Source Code:
              package test.beans;
              In your JSP you don't need the import code of Xiang. You only have to refer the
              path of your bean class:
              <jsp:useBean id="testBean" scope="session" class="test.beans.TestBean" />
              There are some other AppServers that only can deploy Java Beans in packages. So
              if you use packages you are always on the right side.

  • How to make view Java Bean as .ocx file.

    Hi All,
    I want to use a visual Java Bean in Visual basic. So that I can modify all the bean properties as modify properties in a ocx file.
    I used ActiveX Com bridge downloaded from Sun's site. But the packager
    makes a .tlb file .
    This file can only be added as a reference in visual basic but not as a ActiveX control. Is there any way out to do that???
    Thanks & regards.
    Nimesh

    The packager creates a registry file and a tlb file.
    After registering this .reg file, java bean can be used as an ActiveX control.
    From within Visal Basic, select the "Tools" menu and "Custom Controls" item and add the Bean control that was generated.

  • Urgent : java bean having bidirectional one to many relationship

    Hi,
    We have complex requirement in our application.
    We need to copy java bean having bidirectional one to many relationship to another javabean having bidirectional one to many relationship..
    E.g
    Class Basket1 {
    public String color;
    pubic String type;
    public List<Basket1> basketList = new ArrayList()
    Class Basket2 {
    public String color;
    pubic String type;
    public List<Basket2> basketList = new ArrayList()
    We need to exact copy Basket1 to Basket2. We are in trouble to copy List of child because we do not have how many child Basket1 have of same type..
    Can someone help us how we can implement such kind of complex object bidirectional one to many relationship??

    I can't see anything bidirectional about these relationships. What I can see is a couple of BasketN classes that look identical so I don't know why they both exist, and they both contain lists of themselves as members, which suggests some kind of tree structure. Nothing bidirectional there. I can see tat these things can form circular object graphs but I don't see why you would want to do that.
    We need to exact copy Basket1 to Basket2And I don't know what that means. Please explain.

  • How to read the current value of hyperlink java bean in multiple record,

    I have used a java bean for a multi-record block item. On When-new form-instance I m using fbean package as follows
    FBean.Register_Bean(hHyperlink,1,'oracle.forms.demos.beans.Hyperlink');
    FBean.Invoke(hHyperlink,1,'setURL','Abc_Entry');
    FBean.Invoke(hHyperlink,1,'setLabel','Abc Document');
    FBean.Enable_Event(hHyperlink,1,'actionListener',true);
    You can see that I am using the number 1 which is hardcoded,for which I will replace with a incremental loop and remove it. Now when I m using the When-Custom-Item-Event, I want to read the URL for the current instance.
    I m using
    vcEventData := Fbean.Invoke_Char('CONTROL.HYPERLINK',2,'getURL');
    to get the second record value , where in I want to avoid the hardcoded 2 or 1

  • WDVisibility type paramter in Java Bean(Web Dynpro DC in CE 7.1)

    Hi All,
    I need to set a WDVisibility type paramter in a java bean and i am able to do so.It imports com.sap.tc.webdynpro.progmodel.api.WDVisibility class .
    The problem is when i am creating a Java Bean model  it is not allowing me to select the Java bean class it gives an error message" Invalid Class : No class files found for JavaBean : com/sap/tc/webdynpro/progmodel/api/WDVisibility".
    The java Bean class exists in Web Dynpro DC>src folder.
    Any Pointers?
    Regards
    Avinash

    Hi Ondrej ,
    Refer the above links to convert the component of the first dc as a public part.
    Then declare the methods which are written in the component controller of the first DC in the interface controller with the same signature.( When method is called automatically component controller method is called)
    In second dc in component controller properties tab add the reference of the first dc.
    Then access the method in second dc as
    wdthis.wdget<UsedComponent name>Interface.methodname();
    Thanks & Regards,
    Ardhendu
