UML diagrams mapped to code?

Hello,
I have the following question?
Is there any online tutorial or literature presenting
sample mapping to code of more complicated(and bigger) UML diagrams,
than the trivial one to one, many to one, many to many associations.
As you can imagine, things get more complicated easily,
especially for fairly inexperienced people?
Thanx

IMHO, you do not want bigger or more complicated diagrams. Make a new diagram. Or a different view of the new behavior that you are trying to put onto one diagram. IMHO, UML should be short and sweet.
You can have a lot of diagrams, but if any one is huge and complicated, how does that fulfill the intent of communicating easilly and "universally" the way a system works? The only huge and complicated drawings I normally see day to day are data models. And that's mainly because they end up looking intimidating to lay-people (read: project managers).

Creating a UML Diagrams for existing code?

Is there a way for netbeans to generate UML Diagrams for existing files? Does it generate them automatically?

Right click on the class, package or project you want to model and select "Reverse Engineer" from the popup menu. This assumes that you're using version 6.

Display problems of UML diagrams

Hi,
I'm using UML class diagrams for a code generation, rev.eng. project etc.
I experience display problems, the classes sometimes are not displayed correctly, or don't show up at all, after I changed something in the model.
The classes have the package as background.
My guess is a partly incorrect drawing order (from back to top).
When I move the slidebar, or enforce a refresh by clicking the package,
everything is drawn from scratch on, and therefore correct then.
Project size: 50+ classes
My first guess was to blame the system, but I'm having the same problems
on a different computer.
Thus, please also state if you have experienced the same problem.
Gets a bit annoying over the time, when doing serious work.

This is a known issue with redrawing/repainting when the elements are containing the container, eg, package. Sorry for the inconvenience.

UML diagrams and Object Oriented programming

In a project for CSC120 at school we have to program a casino using java. We were given a UML diagram of how the professor wants it set up, and I am having some difficulty understanding exactly what some of this means, code wise.
Part of the UML diagram:
Game
userMoney: int
bet: int
playAgain() : bool
askBet() : int
Payout(amt: void) : void
takeBet(amt:void) : bool
I understand the first two blocks, but the last one confuses me. I get that these are the different functions the class will use, but what does the text inside the parentheses mean, and the text after the colon? And what would this look like in code? If someone could post a link to an example program it would greatly help, or just post a simple example here.
Here is what I have so far in the class file:
* ASCIIcasino.java
* Version 1.0
* Alachine
* Last Modified: 01/19/2006
public class Game
     int usermoney;
     int bet;
    public boolean playAgain()
    public int askBet ()
         do
               System.out.println("How much do you wish to bet?");
               scannergameinput = new Scanner(System.in);
          while(!scannergameinput.hasNextInt());
          bet = scannergameinput.nextInt();
          System.out.print("Your bet: ");
         return bet;
    public void Payout ()
         int amt;
    public boolean takeBet ()
         int amt;
}Am I doing this correctly so far, or what am I not getting? Thank you for your time.
Edited to update code.

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)
    }

Practical use of UML diagramming tool....

Hi ,
the use of UML diagramming tool is to present the system to end user (use cases) ... like the Entity Relationship Diagram in the Oracle Designer....
However , i 'd like to ask if the product of this tool can be used as a base to produce something else afterwards in the whole system...
I mean that in Oacle Designer , when the analyst designs the ER Diagram and saves it to the repository... this can be used to automatically generate the tables... in the repository also and then to the database...!!!!!
Is there analogous using UML diagramming tool....?????
Many thanks,
Simon

The UML class diagram can generate Java classes and ADF Business Components.
The Database modeler in JDeveloper can generate the database objects.
Also when you are designing the page flow diagram you are actually building the JSF or Struts flows.
The hands-on-lab that you can find on the right side of this page:
http://www.oracle.com/technology/products/jdev/collateral/4gl/formsdesignerj2ee.html
Shows off some of the model to code capabilities of JDeveloper:

Cannot find UML diagrams in the "New" dialog

I must be missing something simple but I can't for the life of me figure out how to create a UML diagram in JDev 11g. I had previously had the beta version with which I had no problems. But since I installed the release version, there is no "Diagram" category in the "New" dialog.
Are there different packages of the product that have different capabilities? It doesn't seem so from the download site. Or is there an extension I'm missing?
I've searched the forum to no avail.
I'm running on Mac OS X 10.5.6. Below is my version info:
Thanks.

Retro engineering from Java to produce UML diagrams

Hi,
What are the free tools available to produce UML diagrams from the Java code of an application ?
I tried some with Eclipse, but i am not convinced with the results obtained.
Are there good free tools for this kind of task ?
Thanks

How do you generate uml diagrams And decoding java programs

1)Hi i have neatbeans 5.0 i have finished witting my code and i wanted to know if there is a way to generate uml diagrams straight from the code.
2) Also i think i have bought a java programme to improve your memory and i wanted to know is there a way you look in the java sorce code so i can change the settings the file has a dynamic.dll(application extension), a level(dat File) and a unins000(dat file)

What to use For Developing a UML diagrams Tool??

Hi!
I am student of BS(Computer Sciences) and am doing my Final Year Project. I am implementing a research Thesis and my project involves developing an environment that would allow the Modeler/user to draw UML diagrams like Visual Paradigm, Rational Rose etc. I further(if i found time for that) would be writing a "Code Generation Engine" that will generate the Java code for the drawn UML diagrams. I am more than good at Java and am developing my project in Java.
The thing about which i am confused is that how to develop an environment that would allow the drawing of UML diagrams. I was first considering to work on NetBeans Visual Library API but i found it too much Generic, i mean i had an overhead of managing the UML diagram details in terms of my "custom Widgets". Then some one told me about Eclipse Graph Editing Framework(GEF). But i am not quite sure about it. I wanted to ask that should i use NB Visual Library or Eclipse GEF or if there is any other Java Library allowing to draw UML diagram and possibly generating the XMI(a kind of XML standard) of the drawn UML diagrams for parsing it and generating Code.If some one knows a solution please answer!
Any refernce would be appreciated!
thanks,
Hassan Ali.

I am more than good at Java and am developing my project in Java.Perhaps you are good at the java LANGUAGE, but that is not what matters here; you need to be good at system architecture, design and implementation for which Java may be a tool to do part of the job. Why don't you pick something that does not take a team of skilled developers to create over a number of years (and even then the product is generally flawed)?
Remember: papers are more important than the end product when you are in school. I did a project that was basically two web based systems (servlet/JSP/XML-RPC) to which a PDA device could connect to indicate medical problems. I made a few basic apps, one of which was a simple picture of a human on which you could point where it hurts. Depending on the zone that was pressed, the system would determine how alarming it was and if immediate action would need to be taken (the heart of course was red alert). One other such applications was a simple big red button that read PANIC.
The design was pretty basic; web services for application communication, real time management interface to see incoming messages, very basic PDA applications for the end user part. But two things made our grade shoot to the stars.
- one person who entered the project really late (and did no development at all) made an absolutely fantastic powerpoint presentation talking about the elderly and people with heart conditions and such and so forth (queue in pictures of elderly people and children with toothpaste smiles) and there were even truthful statistics thrown in there.
- a last minute addition was that the systems were linked together; if one would fail (which would be the worst case scenario where the power would go out and the backup power supply would not last long enough), the other would take messages and forward them to the failed system as soon as it was up again so no calls would ever be completely lost, even if there would be some sort of a delay.
That was it. The fact that everything worked was nice; the fact that we had a wonderful presentation, a big pile of documents and we managed to work in a backup system was what rocked the world.

How to implement a UI similar to a UML Diagram with connections?

I'm working on an App that has a hierarchy of nodes and connections between them (Similar to Visio, a UML diagram, or Netbeans Visual Library). The nodes can be moved around, connections between nodes are maintained, etc.
The hierarchy of nodes is easily mimicked as JavaFX Nodes in the scene graph. Implementing the UI for the connections however has proved to be trickier. Here are 2 issues I'm trying to solve:
1) Connections need to track the positioning of their 'endpoint' nodes. Let's say a connection is an arrow connecting 2 arbitrary nodes in the hierarchy. The connection is itself a JavaFX node but in a different parent than the endpoint nodes. There doesn't seem to be a way to be notified that the endpoint nodes' location in the scene has changed, only their local bounds. Because there could be a whole sub-hierarchy of nodes being moved at a time, the connections need to reposition themselves whenever one of its endpoint nodes move in the scene (or should I say - move with respect to the common 'root' pane of the nodes and connections). Any ideas on how to implement this would be appreciated!
2) I wanted the connections to 'float' independent of the nodes. I thought the StackPane would be ideal, (back pane for nodes, front pane for connections), however, the front pane "steals" all the mouse events from the back pane! There's an almost useful method called 'setMouseTransparent', but it applies to a Node AND all of its children. Thus calling this on the front pane means the Connections no longer get mouse clicks. Blah... am I missing something here? Why isn't there a setMouseTransparent() method that doesn't apply to the children? I'd like the connections (thin lines using 'Path') to get mouse events, and otherwise nodes in the back plane should get them.
As a workaround to 2, I bailed on StackPane and use a regular Pane to hold both the nodes and connections. But I need to ensure the connections are always at the 'end' of the list of children... But that's an ugly solution. I feel like either I or JavaFX am missing something here.
Thanks for any suggestions,
Craig

So you need to update the connections between nodes when the nodes are moved around?
But because the connections aren't in the same immediate parent as the nodes they are in a different "local" coordinate space... you want to somehow listen to a node's location in terms of the scene coordinates? So even though the nodes local coordinates remain the same the node moves because it's parent moves and there is now way to observe that directly. Is that right.

Class mapping sample code error

Hi !
There is an error in a Developers guide mapping sample code: p.156-157.
(Examples 7.11,7.12 and 7.13).
For example, in 7.12 we have:
<class name="Tabloid" persistence-capable-superclass="Magazine">
<extension vendor-name="kodo" key="jdbc-class-map" value="flat"/>
.... indicator extensions ...
.... field metadata ...
</class>
instead of jdbc-use-class-map in the key attrribute of the extention tag.
Please, fix it.
Best regards,
Alex.

Actually the sample is correct. It shows the mapping information if you
are using metadata extensions in place of .mapping files. To map a class
via metadata extensions, you use the "jdbc-class-map" extension key.
This is distinct from the "jdbc-use-class-map" key, which you can use to
tell the mapping tool what kind of mapping it should create. So in sum:
jdbc-class-map: Used at runtime by the MetaDataMappingFactory to map a
class to its schema.
jdbc-use-class-map: Used at dev time by the MappingTool to indicate that
the user wants a specific type of mapping to be installed.

UML diagrams using Jdeveloper 9.0.3

I would like to get some help from people who have used Jdeveloper 9.0.3 for creating UML diagrams.
scenario
I have 2 packages namely com.pack.bo and com.pack.ejb created using Jdev.
I have business objects represented in UML inside bo package and have SB's inside ejb package.
Now how would i show the relationships from ejb's to bo's diagramatically ?
Is there any way to show the above mentioned ?
Thanks

Hi,
You could use the Dependency relationship to show the connection on a diagram. Also you could use Notes and Note Attachements to further annotate any relationship.

Gerard Davison

UML diagrams in web pages-Any posibbility in near future?

Is it possible to have a web pages that allowed user to draw UML diagrams and also provide application in
web development?

You asked that question the other day. Why did you create a new user account to ask it again when the original question was given reasonable answers?

Map UNSPSC code to Material Group for punch-out catalogues

Hi All,
can anyone share an experience with the best way of mapping UNSPSC codes to Material Groups for punch-out catalogues.
I've been looking at the Schema config under the Content Management section in the IMG (Supplier Relationship Management > SRM Server > Master Data > Content Management > Mapping for Schemas) but can't really find any docuemtnation to describe exactly how this can be used.
I guess the alternative option is to create a custom table and use the BBP_CATALOG_TRANSFER BADI but if this can be done as standard using config rather than ABAP developemnt that would be a preferable solution.
Thanks
Chris

Hi,
Best way is to activate the BBP_CATALOG_TRANSFER BADI. this encompasses or can be customized accordingly to
1. To map UNSPSC with Product Categories/Material groups (however custom z table needs to be created which does the mapping)
2. Some supplier catalogs will send too much information, most of which is not necessary for SRM, here whatever is needed can be filtered out
This BADI overall enriches the data transferred from the supplier.
hope this helps!
Thanks,
Prashanth
