Ternary Association In a class diagram

Hi
Please help. I need to depict a ternary association icon between 3 Classes in my Class diagram.
I am using Java Studio Enterprise 8's UML tool.
The modeling palette does not make provision for this type of association.
Is there a way to depict the ternary association icon, or is there an update for the Modeling palette in the class diagrams?
It is the little diamond, looks the same as the decision icon.

I filed one for neext release http://www.netbeans.org/issues/show_bug.cgi?id=79744
It's unlikely functionality will be added in patch to jse8.

No association lines in class diagram

In my class diagram, there are no association lines connecting the classes.
I notice that in the BankApplication tutorial, the class diagram has full lines and dashed lines. The structure in the "Model" folder is different from mine. Will this have any effect?
Model
    bankpac
        BankAccount
        Checking
        etcMy structure is:
Model
     org
          CompanyName
               sample
                    Class1
     Class2
     Class3
     etc"Class1" contains "main"
I selected everything under "Model".

If they are listed under project tree but not shown on diagram, then it could be something wrong with diagram presentation logic The relationships shown in the model tree are the same as shown in the class diagram. That is consistent.
I think the issue is due to way my non-techie mind works.
Here is how I produce diagrams. Most of the projects are samples for a manual, so only contain one class.
1) I select the (only) class for a project, and create the dependency diagram.
2) From the dependency diagram, I reverse engineer every operation for that class in sequence diagrams.
Obviously, the master class sends messages to many other instances of many other slave classes. I assumed that the class diagram for the master would show the aggregation of all the slave classes that appear on all the sequence diagrams. Even if the internal structure of the slave classes (attributes, operations) would not be known, at least the class names would be known.
Even after reading "UML Distilled" and reading the Agile web pages, I still think that would be the case.
It seems that Studio only displays a slave class on the class diagram if the internal structure of the slave is known. Maybe that's the correct convention.

Drop6: Java/Class Diagrams - associations + thumbnail isssue

Hi JDev team
I'm having a play with the Java/Class Diagrams in 11g Drop6 and importing existing class structures to display.
Under an ADF BC project I've created both a Java Diagram and a Class Diagram, and added the "oracle.jbo.server.AppModuleImpl" class. I then right click on the imported class in the diagram, then Show -> Related Items, and it imports a large array of classes as expected.
2 problems I see:
1) Minor issue: If you layout the components using the Diagram Hierarchical Top to Bottom layout option, the thumbnail view doesn't zoom out far enough to allow you to move around the whole diagram.
2) In the diagram, the imported elements only seem to show Generalizations (extend) and Dependencies (interfaces), yet not associations (ie. one class includes a by ref-variable handle to another class). I'm sorely missing this 3rd feature. Am I missing something to enable this? It used to do this in 10.1.3, but with the old 10.1.3 diagrammer tool. Has this feature been dropped?
Cheers,
CM.

Extending the UML class diagrams with JDeveloper Extensions SDK?

Hello,
I studied the JDeveloper Extension SDK docs, but couldn't figure out how to write extensions that support UML Diagrams.
What I would like to do, is to pin a different data model under the class diagram view.
Well if you can't do that. In the worst case, my extension would register with a regular class diagram and listen to its events and and refuse particular changes. It would also create or use an empty class diagram and fill in the classes and associations in it. (this is less clean but I could live with it).
Thanks in advance for all your suggestions.
Slawek

By definition you can change classes through the model so I guess the problem here is that the model cannot apply updates to something that it is pointing to the the compiled version of.

Creating OO database objects by using class diagrams in JDeveloper

I am new to use JDeveloper. I create UML class diagrams (using Entity Object) in JDeveloper, which has inheritances and associations, and then choose Create Database Objects... try to create oo database, but it only create some tables in the database, not any object types ... .
What do I missed? Or I have to create those oo database objects manually?
Thanks.

Tony,
You can use database object types with BC4J, but only to implement BC4J domains (these can map to object types).
For performance reasons, it is less practical to generate a table of object types for a complete EO. Most users view the BC4J layer as the 'pure' OO model, and map to a relational datamodel for optimal performance.
Below some steps to create a DB object type for a domain:
You can create Oracle Object Types in the database by creating a business component domain and then forward generating the database object. Forward generation of object tables from entity objects is not supported. To forward generate an Oracle Object Type from a new domain: In the System Navigator, right click on your business component package and choose Create Domain. When the Domain Wizard opens, review the information on the Welcome page and click Next. Enter a Name and Package for the domain or accept the defaults. Select the checkbox for Domain for an Oracle Object Type. Do not select any items on the Available Types list, as you are creating a new one. Enter the name of your new type in the Selected Type field. Click Next. On the Settings page, click New. Provide a name in the New Domain Attribute box. Select the appropriate Java type a[i]Long postings are being truncated to ~1 kB at this time.

UML Modeling for Class calling another class in Class Diagram and Sequence

In my application, business delegate is calling Session Facade through business interface. Session Facade is implementing business interface which includes my application business processes.
In my class diagram, I am showing business delegate, business interface and Session Facade.
What kind of relationship should be shown between
1. business delegate and business interface
2. business delegate and Sesion Facade
I am not very sure wthether relationship mentioned above are really need to show.
What should be calling sequence in sequence diagram. Do I really need to show business interface in callling sequence of sequence diagram or I can show business delegate is calling directly to Session Facade.
Thanks
San

In my application, business delegate is calling
Session Facade through business interface. The delegate is interacting with what exactly when you say "through"?
If the delegate uses an interface then there is an association.
If it is getting an interface implementation from some other object then there is an association there.
Given the above then there is no relationship between the implementation of a interface and the delegate however.
Session Facade is implementing business interface which
includes my application business processes.The implementation would have associations to the objects that it is providing a facade for.

UML modeling for class diagrams, could not generate code for modified diagr

Hi,
I'm using Java studio Enterprise for creating class diagrams and generating code from the UML using round trip engineering. I'm able to create class diagrams and generate code from the diagram. I tried modifying java code for classes and saved it. Now if I try and modify the diagram its not updating the java code associated with it.
Please suggest the workaround or so.
Thanks
Sunita

Maybe the linkage between the source and model class element is broken. Try to expand the class element from the project tree to see if a source file artifact node (under the class that displays the pathname as the name of the node). If not, that's why. Then, the workaround is to manually add the pathname to the java source file. Here are the steps:
- expand the class in question
- select the source file artifact node
- from the properties window on the right side of the ide, enter the exact pathname to the java source file and press the Enter
It should work now.

JDev Java class diagrams - how to associate 2 classes to parent via Map?

I am using 9.0.5.1 and working on some simple Class diagrams. I have learnt how to use the @associates javadoc tag and association editor to get associations displayed between classes that use Collections. However, it seem that I cannot associate the classes used for the "key" and "value" in member Map. Only a single association per member variable appears to be supported. Is this possible?
In case the above doesn't make sense, here is the code from the class with the Map member:
* @associates <{score.ContentItem}>
* @associates <{score.ScoreConsolidator}>
protected Map descriptionMap = new HashMap();
The diagram tool only seems to recognize the last @associates tag. I have tried a few syntaxes for refering to multiple classes to no avail.
Thanks
Drew

Drew,
Your correct, we do only support one associates tag. The associates tag indicates the collection type of the association, and only the first associates tag will be read.
The best way to indicate that an association is indexed, or keyed, by a certain type is to draw a dependency between the association line and the key, or index, type.
Thanks,
Geoff

How to create OO Database from class diagrams?

I am new to use JDeveloper. I create UML class diagrams (using Entity Object) in JDeveloper, which has inheritances and associations, and then choose Create Database Objects... try to create oo database, but it only create some tables in the database, not any object types ... .

If the Location of the datafiles is similar to that of source database then you can consider below steps
Create Oracle Service using oradim
set ORACLE_SID=NEWDB
oradim -new -sid NEWDB -intpwd passwordofthesys -startmode M
Connect to the RMAN
rman>rman target /
restore spfile/pfile and control file from backup
rman>restore spfile to pfile '_localtion of the initNEWDB.ora_' from '_location of the SPFILE Backuppiece_';
rman>startup nomount pfile='localtion of the initNEWDB.ora';
rman>restore controlfile from 'file location of the controlfile Backuppiece';
rman>alter database mount;
Catalog the RMAN backuppiece of source database
rman>catalog backuppiece '_location of the rman backuppiece of source database_ ';
resotore & recover database
rman>restore database;
rman>recover database;
open the database with reset logs
rman>alter database open resetlogs;
rman>create spfile from pfile;
rman>shutdown immediate;
rman>startup;
==================
If you have access to source database then you can clone using below rman command:
+rman target _<source database>_ auxiliary _<new database>_+
rman>duplication target database to _<your new database name>_;
==========
If the location of the datafiles and logfiles are different from source database then you need to add db_file_name_convert and log_file_name_convert to the pfile before starting the recovery process.

Class Diagrams, Stereo Types

How do I set the stereotype of a class in a UML class diagram. I have tried setting the visual properties to display stereotypes but JDev only displays <<class>> for the stereotype. I would like to be able to assign the stereotypes entity, controller and boundary and have the shape of the diagram change to reflect those stereotypes. Can I do this with JDeveloper?

The current version of JDeveloper does not support user defined stereotypes, and displays only the standard stereotypes (class, interface, package, association, etc). User defined stereotypes is something we are looking into for a future version.

Broken wire : Refnum Class diagram objet

Hi,
Many times on my applications. On several computers, different project and LabView version (2011 to 2014).
A "Refnum Class diagram objet" needs to be "updated" because its wire is broken.
The attached example shows a valid WaveformChart Refnum class reference which is suddenly and aleatory "broken" and needs to be reset. Otherwise the vi is broken ...
(In the example attached the Refnum "selected" by labview ar Control and "XControlTREE", the problem has no relation with its existence.)
Thank you
Best regards,
Ulysse

Hi Gerd,
I have had problems in the past with passing control references into subVIs. I had these problems because the strict control reference is often incompatible with a non-strict refnum control, or a strict refnum control of the wrong type. For example, if you have a multi-selection listbox, but you try to wire that control reference to a listbox reference associated with a scalar datatype (single-selection), you will get a wiring error.
The easiest solution for these problems is to right-click on the control reference and choose Create > Control. Then, copy this control into your subVI and use it as the subVI input. I think this will solve your class conflict problems.
If this doesn't work right, let me know and we can talk further...attachi
ng a sample LLB that demonstrates the problem would be helpful.

UML Class Diagram MVC

Hi,
I am designing a piece of software that will be used as a game client for a MUD server. At the moment I am trying to draw the class diagram but am unsure of the association between the MVC components.
here is the diagram:-

Do you know, I never even checked this thread after my last post. i had a few people who understood my problem and were helping. Until you suggested that I was being spoon fed and then no more help. Thanks for that, must return the favour some day.
Also even though you mention in this thread that your time is very preciousand won't be spent doing someone elses work for them you managed to spend long enough posted abusive comments on the board so well done for that.

Java Source Code to UML Class Diagram

Can anyone tell me exactly which kinds of relationships may be identified for a UML CLass diagram, directly from 'static' source code..
Note that I am developing my own case tool which will convert from java to uml..
At the moment, I have only managed to get Inheritance and Association relationships..
Where Association is identified by looking at the types of all variables belonging to a class (excluding method variables etc) and if the type of the variable is non-primitive, than I have deduced it is an association relationship with that class.
Would this be the right approach?
Secondly I have noticed in JBuilder, it models dependency relationships by getting all the Imports at the top of the java source file, is this right?? also I have read that a dependency can be modelled by the variable types in operation arguments (paremeterS ?)..
I would also appreciate if someone could clarify the difference betweeen Composition and Aggregation for me and explain if it is possible to identify the two relationships directly from java source code..
Last but not least, what about multiplicity ? am I right in thinking that an instance variable is 0-1, an array declaration is seen as 0-n (fixed number) and a Vector/ data collection.. is seen as 0 - * (any number)..
Thanks for any help,
Regards
Tony.

although this post is way old it could do with a decent answer.
some guidance can be taken from JSR26: UML Mapping for EJB
find it a www.jcp.org
also this research paper on consistency of reverse engineering between uml tools
http://citeseer.nj.nec.com/545406.html
Where Association is identified by looking at the types of all variables belonging >to a class (excluding method variables etc) and if the type of the variable is >non-primitive, than I have deduced it is an association relationship with that >class.
Would this be the right approach?Yes. You could also say that if it is a java.* type then it would also be an attribute.
Secondly I have noticed in JBuilder, it models dependency relationships by getting >all the Imports at the top of the java source file, is this right?? also I have >read that a dependency can be modelled by the variable types in operation >arguments (paremeterS ?)..JBuilder would be consistent with JSR26, and that's how i intend to implement in ArgoUml.
I would also appreciate if someone could clarify the difference betweeen >Composition and Aggregation for me and explain if it is possible to identify the >two relationships directly from java source code..Composition is a stronger form of ownership. the composed class is owned only by 1 class. Its lifetime is strongly linked to its owner - ie. it is not created before its owner and it is destroyed before its owner is.
eg. leg of a table.
Agregation is weak ownership. the owned class may be owned by several classes.
eg. a company is owned by many shareholders.
Last but not least, what about multiplicity ? am I right in thinking that an >instance variable is 0-1, an array declaration is seen as 0-n (fixed number) and a >Vector/ data collection.. is seen as 0 - * (any number)..sound right.

what is the differene between class diagram and er diagram .....pls explain with examples

<b>Diff btw Class Diagrams and ERD's:</b>
Class diagrams and ERDs both model the structure of a system. Class diagrams
represent the dynamic aspects of a system: both the structural and behavioural features.
ERDs, depicting only structural features provide a static view of the system.
Elements of a class diagram:
>class
>association
>binary
>n-ary
>Aggregation
>Composition
>Generalization

>Association Classes
Elements of Entity Relationship Diagrams:

Can Papyrus show a list of all Associations of a Class?

Hello
Suppose I am working on a Class Diagram and I would like to have a list of all associations that a Class participates in, within the scope of the model.
Or I am working on a Use Case Diagram and I would like to have a list of all Use Cases that a specific Actor participates in within the scope of the model.
It would need to be real time by clicking on a view, not generating a report and looking thru it.
Is my understanding correct that this cannot be done in papyrus? Or maybe one can define a Profile that would support this functionality?
Thanks for any info.

Hi Ri Fr,
What you are looking for is a query, so a profile would not help.
In as far as I know, there is currently no such explicit query. There is actually little related to traceability reporting (of which your request is an aspect) within the tool at this point.
However, all the information for both explicit and implicit traceability queries is in the model, so it should be possible to create such a query as you want using existing customization capabilities of the tool.
Although I am not familiar with it, Papyrus can also show model information as tables - perhaps there is a way to get to the information that way. But someone more familiar with that capability would have to chime in.
