UML Class Modeling Using JDev

I'm trying to create the java classes from a UML class diagram. When I try the transform -> model only, the classes I get don't have any of the related elements in them, regardless of if I use agregation or association. I expected to see a collection or just an instance as attributes. Is this not part of the functionality? Do I need to do this manually? Am I forgetting something about UML modeling?

This is a valid use case. To make the transformation work, you must supply a UML model where the association ends are (i) navigable and (ii) have a name.
Thanks, Guus (JDev PM)

Decompiling class files using JDev?

Is this possible? If so, how?
If not, does anybody know of any extensions written for JDev which uses JAD or any other decompiler?
I would prefer the extension to be JDev 10.1.3 compatible.

Oracle9i JDeveloper Beta - UML - Class Modeling

I have beeing trying to import an application that I exported from 6.0 into 6i and I keep onb getting an error that say it can not modify the storage of a blob. There is a statement in the DLL that trys to alter the storage on a blob in one of the XT% tables.
Does anyone know how to get around this?

You can't import in 6i application systems You exported from 6.0.
You must use the migrate option i RAU and hope it works.

Creating UML sequence diagrams using UML Modeler

Has anyone tried to generate UML sequence diagrams using JDev's Modeler utility. Is there a workaround for creating sequence diagrams. Does Oracle have an very near-term plans for supporting sequence diagrams.
Thank you.
Antonio

While I've done a bit of work with UML, I'm by no means an expert, so this may be a dumb question...
Isn't the point of UML (and other modeling languages) to abstract the design of a system away from the implementation? I'm hard pressed to think of a situation where a UML diagram would change based on the language chosen for implementation.

Understanding Sun Idemtity Manager using UML Class Diagrams

If you are a Sun IdM beginner and want to quickly and logically understand the relationships between various components in Sun IDM, then you should take a look at this:
http://objectsource.com/blogs/2010/02/understanding-sun-idm-using-uml/
You can also download all the UML diagrams from there.
For those of you who understand UML, you definitely know a UML class diagram is a picture worth 1000 words.
I never remembered all of these, so I used to carry a copy of these with me to custmer requirement and design discussions.
Whenever customer asked details that I could not recall or was not sure, I'd pull these out as a cheatsheet to confirm and further elaborate on the design approach for the Sun IdM feature implementation.
NOTE: I am the author of that blog as well. A little background on this post -
I wrote the blog post a few months ago and totally forgot about it.
A few days back, I installed wordpress site stats on my blog and I was amazed to see how many people look for Google terms "Understanding Sun IdM" and end up at my blog post.
I thought - "Hey If it was so useful to these people, then I believe it will be useful for many more" (especially developers from Java background that have turned to Sun IdM professionals)
Hence the post here.
A few years back, I started using Sun IdM and was absolutely unsure where to start and what relationships exist between various components. I painfully started to understand them by going through the admin console and started drawing out these diagrams. They were sitting in my vault, but I set them free a few months back.
Had I known what I know now, I would have released it much earlier.

playAgain() : bool
askBet() : int
Payout(amt: void) : void
takeBet(amt:void) : boolThese are methods of the "Game" class, and what is inside parentheses are called parameters.
"void" and "bool" are return types.
public boolean playAgain()
    }In this code you have specified boolean as a return type, so you need to return a value of type bool.
As for the void part, you don't need to return anything.
Code should look like:
public boolean playAgain()
         return true; //Or return false
public void Payout ()
         int amt;
    }You need to get :int amt" in the parameters, and since its voide nothing needs to be returned.
public void Payout (int amt)
    }

How can I add a Text Template Binding to an UML Class within a MenuCommand Execute Method?

Hey,
I am using Visual Studio 2013 Ultimate with Visual Studio SDK and the Modeling SDK.
I am trying to develop an Visual Studio Extension (VSIX) which contains new MenuCommands.
So if I execute a MenuCommand I want to add a new TemplateBinding for a specific class
something like that:
IClass aspectClass = rootPackage.CreateClass();
aspectClass.TemplateBindings.ToList().Add(new TemplateBinding());
aspectClass.CreateTemplateBinding();
aspectClass.CreateTemplateParameter();
I have already created a new text template file (.tt) and I also want to pass values to this text template file when the
menu command will be executed if this is possible?
So the goal is
1. To execute a custom menu command to add a custom text template file to a specific UML Class
2. To execute the "generate code" menu command to get a generated CSharp file which is conform to my custom text template file
I know this is possible via the GUI, but is this also possible via code?
Thank you very much for your support

BPA: Unable to inlcude existing UML Class assocs in other diagram instances

Hello,
I have created some UML Class diagrams in Oracle Business Process Architect 11gR1 (490292) (SR 2010_07). When I create a new UML Class diagram I am able to drag-and-drop existing UML classes to the new diagram, but when I try to include some existing binary associations (that exist between the included classes) they are not included. I try to inlcude the associations as follows:
1) Create a new UML Class diagram;
2) Find some UML classes (that have an existing association between them) in the Designer Exprorer tree and drag-and-drop them in the diagram;
3) Select one of these UML classes in the diagram (so the "Properties" panel fills with the details of the selected class);
4) Go to the "Relationships" tab of the "Properties" panel and find the relationship that represents the requested binary association;
5) Select the relationship and click the button "Show".
Unfortunately, nothing happens (i.e. the association does not show in the diagram). The above sequence works fine in other model types (with other object types, for example in IE diagrams) but it does not work in UML Class diagrams.
Am I doing it in a wrong way? Is there any workarond if this is a bug?
Dimitar

This problem seems to be a bug. However, I found the following workaround:
1) Locate the UML classes on the new diagram;
2) Try to create a new binary association between them. The BPA tool will check if there is an existing association between these classes and it will open a dialog box to ask you whether to create a new association or to use an existing one;
3) Select the necessary (existing) association in the dialog box instead of confirming creation of a new one and the selected association will appear on the diagram.

9i JDeveloper UML classes

Hello,
I have installed Oracle's 9i JDeveloper release candidate 2 on my Red Hat 7.2 Linux box.
I was doing the tutorials of the user's guide and when I tried to do UML classes, I got an error stating that it could not continue with the execution.
I installed the 9i JDeveloper Release candidate 2 on my windows 98 and when I tried the same tutorial, the UML classes were created successfully.
Does anybody know what am I lacking? or is this a bug in Linux?
Thank you in advance.

Its not that, u have the freedon to use any OA patched jdev version, it depends on ur instance patchset level.See metalink note 416708.1 to know which Jdev u need to use as per ur apps instance patchset level.

Generate Data model from Class model

I am using JDeveloper uml features for a first time, so I am interested if there is a option that I can generate class model to the data model.
If I have class model and than when right-click select Generate , there is a option to generate data model from it.
But it is dimmed. Is there any precondition to achieve before this option become possible.
Thanks in advance .

The UML Package model could not be resolved - SOLVED

I am using Perforce with JDeveloper 10.1.3.2.0. I have imported a project into Perforce on one machine, then 'p4 sync -f' on another machine. I then created a new application on this machine and added the projects to it. Now, when I try to open a diagram in package 'model', it gives this message:
The UML Package model could not be resolved
The element may have been moved or deleted from the file system, or the Model path, source path or classpath may be incomplete. This error can also occur when the element was found, but errors in its definition prevented it from being loaded. Examine the error stack for further information on the exact cause.
It also looks as if certain other files in the other projects are missing - it looks like a problem with the Perforce extension to me, or is it because I do it wrong?
Message was edited by:
jandersen

It gets stranger and stranger, I think.
As I told, I imported the project into Perforce, to a directory called /dtl/admintools, and found that I could still open all files - I did find that one file was missing (/dtl/adminstools/sysadm/SysAdm.jws), so I added it to Perforce. I then removed everything under /dtl/admintools and sync-ed it out from Perforce on the same machine - it still worked fine.
I then went to my home computer and did the same thing (over a VPN) and checked that I had received all the files, which I had. I then tried to open /dtl/admintools/sysadm/Model/model/model/SysAdmDiagram.oxd_bc4j, which contains entity- and view objects - this give the error message. I can see all the objects listed in the structure list, but if I try to open any of them, I get the same message. There are no error messages other than the one that pops up.
Both my workplace computer and my home one are AMD 64 machines running Gentoo Linux and it's the same version of JDeveloper too.

Five Class Model QoS Design?

Hi all,
I work for a company with a medium-sized network. There are about seven MPLS WAN sites. One of them is a data-center. The rest are sites with mostly users. The sites are dispersed through-out the continental United States.
Currently, the network is a basic data IP network with no QoS. There are a few projects slated for 2010. One involves implementing VoIP between just two sites. The other project calls for implementing IP-Video-Conferencing between the majority of the sites.
Should I start out with just a five-class model?
        - voice
        - call-signalling
        - IP video-conferencing
        - streaming video
        - default-traffic (all data)
Is there really need to break down the data traffic into QoS classes as well?
As always, thanks an advance for your help.
-Mike

The answer is - it depends
Cisco recommend using the full model even if you don't actually use them or allocate bandwidth to them. That way you then don't have to go back and change all your configs if you need to add another class.
Weigh this against where you intend to use QOS primarily ie. on the WAN or LAN or both. The key thing is to talk to your WAN provider to understand what classes they provide ie. how many, how much each class costs etc. If they only provide 5 classes for example you could in theory simply use 5 classes internally and map these to the provider classes.
However there is nothing to stop you using 11 classes internally within your LAN and then mapping multiple internal classes to a single provider WAN class.
The other thing to bear in mind is the applications that make up the company data. Are there a few recognisable critical apps to the business of the company compared to the majority which are not critical. If so it may be worth reserving a class for these apps, even if you don't use it at the moment. If the time comes that the company then needs better performance for these apps you have already provisoned for it (makes you look good !), and you can simply map it to either a new provider class or an existing provider class with increased bandwidth.
It is basically a trade off between complexity of QOS configs and making things easier in the future and a lot depends on the apps that the company runs.

UML classes with 9i JDeveloper

Bob,
The error you are getting is not related to connecting to the database. Instead, it is a bug inside of JDeveloper that is related to expanding the database connection in the Navigator.
Off the top of my head, I'm not sure what the problem is, but I will try to look back through our bug logs to see what I can dig up. In the meantime, can your confirm for me that the version of JDeveloper you are using is the 9.0.2 production release?

Hungarian Naming Contentions for UML Class Diagram

UML class diagram should be generic for all the available object oriented language and should not be language dependent. If we follow pure java naming conventions in UML class diagram, which make the UML class diagram Java language dependent not generic.
I am trying to combine Hungarian Naming Contentions with Java Naming Convention so variable name will follow x_y schema where x_ is according to Hungarian notation attached with class attribute, which is named according to java naming standard. This naming standard satisfies UML naming convention and will also help in java programming.
For an example,
i_userNumber Here 'i_' is a Hungarian notation representing type of variable attached with class attribute . This indicates that the attribute is an interger , which is named according to java naming standard.
Feedback Please

You're going to get a gozillion answers to this question, and all of them will be both right and wrong to some degree, so I will give you my thoroughly opinionated answer to go along with all the rest.
I am not a fan of Hungarian notation for one fairly fundamental reason. Java is a strongly typed language, thus it doesn't need indicators of type. By putting a type indicator on a variable you create potential problems when you change a data type. Won't happen? I am currently sweeping through a major portion of the application I'm working on changing data types for masses of variables because the database guys took a whim to change the data type in the database. If I were using Hungarian notation, not only would I have to change the type, the parameter type and return type for the accessor mutator methods, I'd also have to change the name, the name of the accessor and mutator methods, and anywhere that the variable is modified directly.
The name of a thing should speak for its self. It shouldn't need an indicator flag on the front to tell me what it is.
But you're talking about UML not Java code. The same thoughts apply. The name should speak for the thing it represents without the need for additional clarification.
Hungarian notation in my not so humble opinion adds complexity by requiring the development team to spend effort learning, understanding, thinking about, processing, manipulating, touching, dealing with what is essentially a thoroughly artificial naming scheme.
Just my thoughts on the subject. Your milage may of course vary wildly.

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.
