  • Out of memory error importing a JPA Entity in WebDynpro Project

    Hi All!
    We are having problems importing JPA entities in a WebDynPro project, this is our escenario.
    We have two entities, entity A that has a ManyToOne relationship with entity B and at the same time entity B has a OneToMany relationship with entity A. When in the controller context we try to create a node usign a model binding to Entity A we got an Out of memory error from NetWeaver DS. Trying to figure out the problem we identified that in the model that we imported we got the following.
    Entity A
        Entity B
            Entity A
               Entity B
                  and so on....... without and end
    What are we doing wrong? Or how can we avoid these behavior?
    Regards,

    Hi Kaylan:
    Thanks for your reply. You are rigth about the error that we are getting. This is our scenario.
    We have a ejb that in some of his method uses the entity Lote, and this entity has a relationship with entity Categoria. When we import the EJB using the model importer netweaver imports the EJB methods and the entities that they use.
    So after doing this besides the ejb's methods we got these two entities that are the ones that are generating the error, when we try to create a context node using the Categoria entity.
    @Entity
    @Table(name="TB_LOTE")
    public class Lote implements Serializable {
         @EmbeddedId
         private Lote.PK pk;
         @ManyToOne
         @JoinColumn(name="CO_CATEGORIALOTE")
         private Categoria coCategorialote;
         @Embeddable
         public static class PK implements Serializable {
              @Column(name="CO_LOTE")
              private String coLote;
              @Column(name="CO_ORDENFABRICACION")
              private String coOrdenfabricacion2;
                   ^ this.coOrdenfabricacion2.hashCode();
    @Entity
    @Table(name="TB_CATEGORIA")
    public class Categoria implements Serializable {
         @Id
         @Column(name="CO_CATEGORIA")
         private String coCategoria;

  • DNS Error shown when running the Webdynpro project

    Hi All
       When ever i try to run the webdynpro project i am getting the Error
    Bad Gateway
    The following error occurred:
    [code=DNS_HOST_NOT_FOUND] The host name was not found during the DNS lookup. Contact your system administrator if the problem is not found by retrying the URL.
    And also in SMMC when i click on Blue node the same error is shown.
    The Host name in which i have installed the WAS is right.
    How do i rectify it.
    Regards,
    Vijaya.

    Hi Vijaya,
    This could be problems with the static and dynamic IPs.
    Try ping command
    1. ping -a IPADDRESS
    2. ping HOSTNAME
    The above two commands should resolve to same machine.
    If not the system administrator should delete the entry in DNS.

  • Is there a way to have two separate projects open in different windows?

    On my old editing software, I could have two separate projects open at the same time. I could copy clips from Project A, click over to Project B, and paste the Project A clips to Project B. Is there a way to have two separate projects open with Premiere Elements, or will I have to just import and trim every clip within the same project?

    Welcome to the forum.
    Unfortunately, PrE will not allow two Projects to be open at the same time. It will also not allow multiple instances of PrE to be open.
    The workaround, to accomplish what you describe, is to use a ClipBoard Extender, such as ClipMate, which will allow one to Copy a Timeline, or parts of it, from one Project, then Close that one, to Open another one, and Paste the material, that was Copied. Many users employee ClipMate, or similar, to Copy/Paste material from one Project, to another.
    Good luck,

  • Creating a WebDynpro Project in Studio

    Hello,
       I am involved in creating a WebDynpro project in Netweaver studio. I am using Get_Flight_List example project(I got it from the net).
    Whole process of creating attributes and operations is performed.But,when i add teh relavent java code from the example, it gives compiler error.
    Errors are :
    1.getMessageManager() is undefined for the type IWDViewController,
    2.bapiInput is not resolved and
    3.wdGetFlightListComponentController() is undefined for type IPrivateFlightListView.
    Kindly help me in resolving this issue/Suggest a way to create a simple WebDynpro project.

    Hi
    In case there are no errors in the code, CtrlShiftO and a ctrl+space wherever it is highlighting the error should resolve the problem.
    bapiinput must be a object created in the code for the model class.
    Have you created an object with this name.
    In webdynpro section of SDN , you will have e-learning section which has detailed tutorials with sample projects.
    Please look into it.<a href="https://www.sdn.sap.comhttp://www.sdn.sap.comhttp://www.sdn.sap.com/irj/sdn/developerareas/webdynpro">WebDynpro Developer Area in SDN</a>

    go to "DC Metadata" "used DC"  , and "Properties" in context menu
    for all you your components.
    problematic component reference probable has check box "deploy time" checked.
    remove that reference.
    usually only "Build time"  check box must be checked. try to do so.

  • Can't add a webdynpro project to DTR...

    Hi at all,
    I've posted this already to WebDynpro but I don't know how to move it because it is maybe better to post it here.
    I have created a local webDynpro application and as I got access to my DTR I added it to it. Everything was looking fine until I said that I want to remove the application from my client and created the project again.
    On creating the WebDynpro project, the NWDS give me some error messages that some files are readonly!
    (Web Dynpro Generation: Existing output file .../roadmap/RoadmapComponent.java is read-only!)
    After that I removed the readonly flag in the windows explorer and rebuilded the project. But on the next checkin and sync from the DTR I got the same message.
    I deleted the webdynpro project from the DTR and made sure that all files of my local copy were writable.
    But still, if I create the project on the DTR, there are some files that are readonly if I sync them from there...
    Does anyone know what the DTR is doing there, why it's automatically setting some files to readonly and how to solve that problem???
    I read a lot in SDN how to add a project in the DTR, but all that doesn't solve my problem. I have no idea what I can do else.
    I'm appreciated for answers.
    Regards,
    Dennis

    Hi Roy,
    usually you need all your source folders, whatever they are named. For a Par I would assume src.api, src.core and dist. for a regular Java project src (or src/packages).
    If you are working with development component you must include the .dcdef file and the def folder. If the cfg contains files you should also add that.
    As negative list: you should not include the bin folder (where NWDS/Eclipse puts generated classes), nor any folder starting with gen (e.g. gen_wdp for WebDynpro projects should not be checked in. The gen folder itself should never be checked in either, it contains the build results from a local DC build).

  • Two different projects spliced together over each other some how?

    Greetings everyone,
    I thought forum users might be interested in this one. I don't use the forum often so I don't know the history but has anybody ever had two different projects spliced together over each other some how? For example, I was tweaking a project and left it alone for several months. I came back today to work on it and clips from other projects were in it some how. Also the audio from the new clips were in the new project and overriding the existing project. Does anybody know how to restore the two and make them separate them without losing any info. from either one? The thing's a mess. I had 1 video track w/ some subtitles, a voice over, and some music in the background. Now it has two video clips, and two of everything else. It's crazy. I don't think it's a virus or anything. Nothing else on my machine is acting strange. I hope nobody else has experienced this yet can help.
    Peace

    If you have a backup external drive and Time Machine, I would suggest the following:
    Locate this specific clip in your Finder. Highlight it and rename it "old", or something similar.
    Launch Time Machine.
    Go back to a date in time when this clip was as you properly edited it.
    Again, make sure Finder is still open and highlight the clip.
    Click "restore" in Time Machine.
    Open iMovie and you will see your project as you had it all those months ago.
    This works for me when I have an iMovie project behaving badly.
    iMovie is a great application: but just like us, it has good days and bad days.

    Swetha

    Hi Swetha,
    Please try this code in the application which is now launched from the 1st application. You can write this code in the wdDoinit() method OR the firstTime loop of the wdDoModify function:
    String applicationParam = WDWebContextAdapter.getWebContextAdapter().getRequestParameter("A");
    Here "A" is the name of the attribute in which you are setting the parameter value CVNR.
    You will get the URL parameter you have passed to this application from the first application. I hope this solves your problem, if yu have any issues please contact back.
    Thanks and Regards,

  • Combining two iDVD projects into one

    So... I have two iDVD projects both of which are under half an hour and they are both complete. The dvd is all set up, the menus have all been perfected and I like it. Is there anyway for me to set up one DVD and on the first menu of that DVD give the option to go into either of the two DVD's that I have made and have all their menus and everything be just the way they are without me having to redo everything?
    In other words, is there anyway for me to just combine the two projects and add a front page that gives me the option of going into either of the two in order to save DVD's and to archive everything?
    Thanks!

    In other words, is there anyway for me to just combine the two projects and add a front page that gives me the option of going into either of the two in order to save DVD's and to archive everything?
    Sorry, but no. You need to create a NEW iDVD project that includes the content from the other two dics.
