Tree implementation in webdynpro project

Hi,
i want to devlop an application that shows a tree that gets data fron RFC .
user will logged from portal & application will show all his/her subordinates in tree & on click on a
subordinate, all other levels get displayed(if level are in system).
plz help.
Regards,
Amit

Hi Amit,
If the hierarchy of the tree is know at design then you can implement the NonRecursive tree. Refer to the help.sap.com on this:
http://help.sap.com/saphelp_nw70/helpdata/EN/c2/abfceffbacd24185ec7af8a3a2e76a/frameset.htm
However if the hierarchy is not known, then you will have to implement the Recursive Tree. Please refer to the following link in help.sap.com for info:
http://help.sap.com/saphelp_nw70/helpdata/EN/16/1ec1814e566f4baf943c53ccf48552/frameset.htm
The above links also have code to explain how the tree can be populated.
Populate the tree to the necessary level on initialization of the screen or the required action. The remaining tree can be filled when the user clicks on the nodes.
If the child nodes/items are to be populated on click of the parent node, then you can use the onLoadChildren action. When a node is click the action linked to the onLoadChildren is called and the necessary processing can be done to load the data if present.

Application Deployment issue in Webdynpro project

Hi,
I have created an sample Webdynpro project which just displays the name. EAR file has been transformed to SCA file using NWPACKTOOL for deploying the application in JSPM.
When i tried to deploy the SCA file i am getting an exception as,

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.

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;
     @OneToMany(mappedBy="coCategorialote")
     private Set<Lote> tbLoteCollection;

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>
In case you have done all this and still the issues are unresolved, please revert back.

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).

Default system names for several RFCs in a WebDynpro project

Hi , I have a doubt, currently I am adding several RFCs to a WebDynpro project , all of them with the same "Default system logical name" for model instances and RFC metadata..
It is ok to give the same "default system logical name" for all my RFCs" or should I give a different name for each RFC I add to my project ?
Which way do you recommend to configure all RFCs in my project?
Thanks in advance....

Internal architecture of R-tree implementation

Does anyone know where I can get whitepapers which describe the architecture of R-tree implementation in Oracle?
I need it for my undergraduate thesis. It will be a case study of R-tree implementation in Oracle Spatial. Actually I want to focus on why R-tree is implemented while scientists still shape it into a more applicable and reliable state.
But ya, if it is too hard, perhaps I will focus on the architecture itself.
Anyone can help?

Several papers were published in the last few
ICDE, SIGMOD and SSTD conferences about how R-trees are implemented in Oracle.
You can get most of the architecture details from those papers.
