Complex Java Bean Model in WD

I've revised the question.. to make it more simple.
I have 2 wrapper classes, the first wrapper HAS the second wrapper as an object.
When importing the Java Bean Model in WebDynpro, it seems okay - did the context binding, etc. -- until I did an "Apply Template" (as form) on the layout based on the CommandBean (which has the wrapper class).
Now, the fields are not active fields.. I can't change the cardinality -- and I have played around with the relations of the model classes with each other.
Nothing seems to work
Please help.

problem solved.
forgot to completely bind inner nodes.
developers who need more info, do post here so I can help out in any way I can.
Cheers!

  • Expose EJB through Java Bean model importer in Web Dynpro

    Hi,
    I am planning to expose EJB like following:
    1. Create Stateless session bean as a façade for DAO access.
    2. Create DAO to access database. In my case is Oracle DB
    3. Create Java Bean to encapsulate session bean
    4. Import java bean model to web dynpro
    Few of my business method return the object array e.g. Customer[] which contains all properties of customer, and getter, setter.
    Has anyone done this before? Is there any sample code?

  • Import Java Bean model in Web dynpro DC

    Hi all,
    I have created the following DC's on a track:
    1. EMPDic (Type: Dictionary) - DC that contains the database table.
    2. EMPEjb (Type J2EE) - DC that contains the EJBs that have business logic. Created a public part EMPpp that containd the bean classes.
    3. EMPEar (Type J2EE) - DC that contains the EMPEjb module.In Used Dcs added EMPpp
    4. EMPCmd (Type: Java) - DC that acts as the command bean.
    Created 2 public parts 'compile'(Type:compilation) and 'deploy' (Type:assembly). In Used DCs added EMPpp.
    5. EMPWd (Type: Webdynpro) - DC that will contain the Java Bean Model and the application. In Used DCs added 'compile' and 'deploy'.
    Q1.) Now when i try to import the Java bean model by selecting the radio button "public parts of used DCs" and look at the dropdown, i am not able to see any of the jar's related to my command bean DC.
    If i select the radio button "project(source folder)" and click Next it says 'No JavaBeans for import'. Am i missing something?
    Q2) Could someone tell me the exact steps from pt. 4 onwards. ie. whether it is necessary to create the 2 public parts for EMPCmd DC and what should it contain.
    Thanking you in advance.

  • Calling Portal Service using result as Java Bean Model impossible?

    Hello folks,
    we try to achieve to call a portal service (working) which gives as a result a list of object of type com.foo.Report. We want to make use of this class as a model class, so we have the class as a model node in the context. The class itself is part of the service DC.
    Unfortunately at run time it gives us a NoClassDefFound Exception of com.foo.Report.
    As the com.foo.Report is part of the same DC as the service, it is no option to add the PAR public part to the used DCs of the WD DC because then there is this type conflict when we call the service (service look up). Or am I wrong and this is the way to do it? I mean I struggled quite a while to get the service look up right and needed to remove all the PAR/lib used DCs from the used DCs of the WD Project, when I got it working this Model error came up. I also tried to put the Model class in a separate DC but that caused the same error.
    how is it possible to call a Portal service from WD and using it's return vale as a Model class
    our system iis 7.0.17

    Hi Krish,
    In addition to Madhu's suggestion,
    As per the Java Bean Model creation steps, you will need to add the Commanad Bean JAR too in your Project, and while creation of Model, you need to select this Command Bean JAR and not the Bean Project JAR.

  • Simple Java Bean Model in Wed Dynpro

    Hello All,
    I have to develop a WD Java application with an Oracle DB as the backend. To application was designed to abstract the backend interaction into a Java bean model. The data connection and retrieval was successful. To move the data to the context following steps were performed:
    1. Create a java class with the variables to be used as context in the application. Ex: Name, Subject, Email
    2. On interting the ResultSet, set the values to the variables.
    But, only the last row of data is retained. We tried to use array but have not been able to move the ste of values to the context.
    Request your help in this regard to store the set of values into the context.
    Thank you.

    Hi,
    It looks like you are overwriting the same context element when populating it with the values from the resultset.
    Make sure you create every time a new context element and add it to the context root.
    while (rs.hasNext()) {
        ContextElement elem = new ContextElement();  // or something simular appropiate to your element
        elem.setName(rs.next().getName());
        contextRootNode.addElement(elem);
    Hope this helps a little.

  • Diffrence b/w Deploy Time & Design time in Java bean model

    Hi all,
    I have craeted a model using java bean.
    create model->import java bean model->Add JAR->browse the jar.
    There i have got two Radio Buttons
    Design Time
    Deploy Time
    I have worked with this two i have not observed any difference.
    Can anyone give me some idea about this.If possible with an example to?
    Thanks & Regards,
    Lokesh.

    HI Lokesh,
    The basic difference between design time and deploy time is. design time jars are only used when building your aplication and considered to be present already on server. and at runtime application refer to it..
    while if you keep deploy time, then the application itself keeps that jar file with him and at runtime it refers to it.
    i.e. application deploy that jar file on server.
    When you run an application, application need all its dependencied to be present in webdynpro container of server.
    your javabean model needs those jar files at server. so when you chose deploy time. it personly deploy that file on server.
    Iif you keep it as design time then. then you will be  able to build it.
    but if those jar files are not present at the server then your application will not get deployed.
    e.g.
    let A & B are your two applications and they need xx.jar file of a EJB  which is created by you  to create a javabean model.
    now as this xx.jar file is not present at server.
    1. when you create model for A. Keep it as deploy time.
    as application A deploy that xx.jar file on server. B can refer it directly
    2._when you create model for B keep it as design time._

    How can I add the home and remote classes to my webdynpro?
    Regards 
    Richard

    You could try to put the ejbClient.jar (the jar file that was generated in your ejb project) into the lib directory of your webdynpro project.
    Everything in the lib directory is deployed with the Webdynpro application.
    To see the lib directory you have to change to the navigator view in the IDE.
    It is right under the Project root.
    If you have Development Component Projects this is a different story. You can add the public part in your ejb DC (of type assembly) to the DC usages in the WebDynpro DC. The type assembly means then, that the jar file from the ejb project is taken and packaged with the WebDynpro DC. But watch out. For this to work you have to do a real DC build and a real DC deploy not the deploy and run function. Hope this helps.

Java DC: a) Create Class files --> one for connecting Database (JDBC Connectivity) ; other only having Input and Output variables with corresponding getter & setter methods ;and one more class file having all methods. I make Jar file out of this class files and store that within that DC project under _comp folder.
    2. Ext Lib DC: a) Copy the created Jar file in Library and make 2 public parts (one PP for compile time and other PP for assembly time).
    3. SAP J2EE DC: a) Create DC of type Library and above create PPs is added to this library.
    4. Web Dynpro DC: a) Add SAP J2EE DC of Library Type in my Used DCs. b) This will make the  JAR file created in Java DC to be available in options of " Jars from Pubilc Part" and  use all these class files as Models. And Using them we access the Oracle DB and get access to data.
    This proved to long exercise. I want to know if there is any other approach available other than this. I'm aware EJB Models approach, but this will be hit on my performance, so want to avoid this. Yet if any shorter approach is available.
    My Idea behind this long approach is from the SDN provided example on Java bean where in Web Dynpro Project uses a local jar file created from Java project which wraps a EJB Module project and Enterprise Application project. So in DC perspective if we have to include jar file we have to make it public part.

    I want opinions and suggestion on this regard and best available approaches.
    Thanks in advance

    D.V.,
    Here is an option to trun steps 1-4 into 1-2
    As far as you are using your Java classes only from WD DC-s, then:
    1. Put all your Java source in WD DC, create single public part for compilation. Bonus: you may create JavaBean model right here and add it to public part as well.
    2. In other WD DC-s refer public part created above and add run-time reference (via Project -> Properties) to corresponding DC. Now you can use both Java classes and JavaBean model.

  • Problem importing java bean model

    I had importing a lot of classes from my bussiness model but I have some problem with some classes. Those classes uses others from external jars, like common collection.
    I imported common-collection.jar to wd project, but I got the same error. Is posible use external classes in my model? How can I import it? (external jars)

    Hi,
    You have to create a DC of type extyernal library.
    And paste the external library in the libraries.
    And craete public of both types SDA & API.
    Right click on the pasted jars in the libraries folder.
    Right click on the jar>Development Component->Add to public part(Create a one with API radio button selected).
    Repeat the same step selecting SDAs radio button.
    Now add the public part created by you in the Web dynpro DC ur working .
    Thanks & Regards,
