Round Trip UML Tool

Looking for suggestions for a round trip UML tool. Mainly I'm interested in being able to extract UML diagrams from Java source. Ideally, open source, but I'm open to anything if it's really good.
So far I've found ArgoUML, but the support for reverse engineering UML seems spotty.
I've also heard good things about Together and Rational, but both of those seem very expensive...
Thanks for any thoughts,
Johh

I'd be curious to know your reasons for this, given
that
you seem to have quite a bit of experience.UML diagrams created by humans can sometimes show their intent more clearly than code by obscuring details and isolating the important abstractions. Unfortunately, maintaining that sort of UML diagram is expensive. I find it's cheaper to document the important abstractions and original intent with plain text comments.
There are impedance mismatches between UML and all popular programming languages. This forces automated reverse engineering to either arbitrarily reduce detail across the board or burden the diagrams with trivial details. The purpose of a model is to throw away some information. That's why 1:1 scale maps are not popular. Automated systems aren't smart enough to know which information to throw away.
Also, UML is sort of like Esperanto or Lojban. They might be useful in a pinch, but very few people want to speak them all the time. Automatically translating source to UML loses idiomatic information, and it turns out programming idioms convey a lot of useful information between experienced developers.
It seems to me having UML diagrams for other people's
code is especially useful, and can greatly ease the
process
of coming to understand it. Hence my special interest
in a
good reverse engineering tool. But I like UML for
aiding my
own design as well.I used to like it, but after I became more familiar with OO concepts I found it just slowed me down. Perhaps it is helpful while learning. I'm glad I know it, I just don't use it.

  • UML Modeling: Round Trip Engineering

    Hi!
    Yesterday I worked through and tested the UML Modeling: Developing Applications tutorial. Everything worked awsome and I managed to complete step in the tutorial.
    Today, when I started the studio and wanted to play a little more with Round Trip Engineering I found something strange.
    If I add an operation to the java-source using the source editor it do not show up in the UML class diagram but if I add an operation to the UML class diagram it shows up in the java-source.
    Is it me that is doing anything wrong?
    Is this a known issue/bug?
    Win XP Professional
    Java Studio Enterprise 8 with latest update today.
    Sincerely,
    // Paul

    Paul,
    Glad to hear you like the UML tool. Not sure which release/version you are working with so I'll try to cover all the bases hear.
    The UML module was released with the Enterprise Pack (early access version I believe), the live roundtrip was still enabled. Then we pulled UML module out of the Enterprise Pack because we needed to do some overhauling of the roundtrip feature and we didn't want to prevent Enterprise Pack from going beta, so now UML is available via the beta update center. This version of UML has the live roundtrip disabled so that code is not generated with every model manipulation and the model is not updated with every source edit. It sounds like this is the version you are working with.
    There is a strange scenario where the live roundtrip is unintentionally enabled (live roundtrip should never be enabled... ever - this is not your fault). A bug was filed and I fixed it, but the fix was integrated into a different branch than the one available via the update center. This is because we are about to release Java Studio Enterprise 8.1 and so we did all the bug fixing on that branch and all those fixes will be merged with the UML that is on the update center, probably in the next week or two, but a date has not been decided, yet.
    In summary, rest assured that the issue (and many many others) have been addressed, and those fixes will be merged into the version available on the update center very soon.
    Please keep the feedback coming on reverse engineering and code generation as we are rebuilding these features from scratch for NetBeans 6.
    thanks

  • Sun Java Studio Enterprise 8 UML Round Trip Engineering Problem on Linux

    Hi all,
    I know Linux is an unsupported platform but I thought I'd mention that the "Navigate to Source" context menu when trying to generate source from UML is missing.
    If you try to work through the "UML Modeling: Developing Applications" tutorial (http://developers.sun.com/prodtech/javatools/jsenterprise/learning/tutorials/jse8/uml_fe.html) on a linux box, everything goes to plan until step 3 "Choose Navigate To Source from the contextual menu" of the "Continuing Development Using Round Trip Engineering" section.
    I haven't tested it on Solaris but it definately appears on Windows.
    Cheers!
    Mike.

    I just tried on JDS3 Linux and I was able to complete this tutorial from the beginning to the end without any issue. I tried the Navigate to Source option on all classes from the project tree under the "bankpack" package node and source file for all classes were opened in the source editors. In fact, all UML quickstart tutorials have been tested and working as expected on all platforms including JDS3 Linux.
    Which Linux system are you having this problem on?
    Which JSE 8 build are you using (look at product line from Help->About, click on Detail tab)?
    Are you able to see "Navigate to Source" from the contextual menu for any other class from this tutorial?
    As Trey indicated in his response that the source must exist to have this menu option, do you see the corresponding source file generated in the Java project?
    Thanks,

  • Analysis, Design model, round-trip engineering

    ok, here's the point.
    We work with the problem domain and develop the analysis model. The analyst at this stage doesn't concern himself with the implementation details, some low-level code patterns and the programming language (well, let's forget for now about C's multiple inheritance and Java's workaround for it). So, when most of the analysis work is done, we end up with major classes (populated only with some basic attribs & behaviour; then, we have a high-level representation of business processes and corresponding activity diagrams. Of course, this model will be refined at a later stage, but for now it will do.
    Say, we have the model in a project. Now we move to the design level. More and more details are added to the model, sequence/collaboration diagrams are added, we concern ourselves much more with the detailed class behaviour.
    And here's the first question. Should we leave the original high-level diagrams intact and produce separate detailed ones? Generally, they represent the same process, but at a more detailed level. What about duplication of diagrams? Or should we elaborate the existing ones (but then we lose the clear and simple bird-eye view of the problem domain).
    After that, we make a decision to implement the system as a set of EJB's. So, we've switch to component modeling at system design. UML model for these components differs quite a lot from a traditional one, so it can be quite painful to refactor the existing interaction diagrams. But do we need to do it? I agree that having <<EJBImplementation>>, <<EJBRealization>> , etc stereotypes displayed in the analysis model is not a nice solution.
    Another question - is it a good idea to start a separate project for system design and just import/copy the required pieces from a higher-level design model? Or can we get away with combining all stages in one project file?
    Please, read all of the above in the light of round-trip engineering. So, finishing after analysis stage, is not an option, but to lead the whole project to as low level as implementation details.
    I'd like to hear from you, some hands-on experience with similar projects, your approaches. Feel free to comment on the flow of events.
    Best regards,
    Andrew

    existing ones (but then we lose the clear and simple
    bird-eye view of the problem domain).Depends on whether you are concerned about the abstract methodology or more concerned about the implementation methodology.
    For full process control, on a large project, you will have a architecture design which will always reflect the target system but has little to do with the implementation design. If the architecture needs to change it means something was "wrong" with it (which could come about due to a change order or a refinement of the specification of the system.) There might be other associated high level documents which occupy the same level - such as the project plan. This would typically be the project initiation phase which occurs before software design starts.
    Of course you would keep all of the documents. Just as naturally each version would be checked into the version control system.

That is always going to be a architecture or requirements decision (even if it is implicit.) If not then it suggests that there are probably at least three levels to the design process and the J2EE decision is in the top most layer (maybe there is a "high" and "low" level architecture process.) And architecture design must describe why J2EE was choosen and what if any alternatives were considered.
    Again this document will be retained (and checked into version control.)

    In the abstract yes.
    Why? Because in an ideal design environment, a "high" (system) level design is created by a small very experienced set of developers. Then it is handed off to many junior developers for "low" (detailed) design. That doesn't work if you are using the "same" design. This is only somewhat mitigated by design tools that somewhat support this process (or least last time I checked they didn't support it very well.)
    Keep in mind that this is the ideal, and it is unlikely (probability wise) that you are working at or with a company where doing this is feasible much less encouraged.
    Please, read all of the above in the light of
    round-trip engineering. So, finishing after analysis

    Round trip. You start with the documents that have been checked in. You branch the version control tree or just up the version numbers of the docs (depending on how "deliverables" are being handled) and start over.

    Subject: (forte-users) Round-trip database design
    Hi,
    Maybe not 100% the right mailing list but it's worth a try.
    Does anyone use tools to automatically update the structure of an existing
    database?
    For example, you have a full database model (Power Designer) and you've
    created a script to create all these tables in a new and empty database.
    You've been using this database and filling tables with data for a while.
    Now you want to do some marginal modifications on these tables. Add a
    column, remove a column, rename a column, etc.
    Is there a way to automatically change the database without losing data and
    without having to do it manually (except the manual changes in the (Power
    Designer) model).

    Hello Pascal,
    Forte has classes which might be able to scan the database structure
    (DBColumnDesc,etc.). Express use this classes to determine how the
    BusinessClass looks like. We use Forte to create the tables,indexes and
    constraints. We have the Problem that the above described classes are only
    readable but not fillable. The solution for us will be to create our own
    classes in
    the same manner than existing classes are. So we are able to make updates in
    the database structure and maybe able to change the database tables with tool
    code. Another reason for us to have the database structure in the
    application is the
    ability to see the table structure on which the Forte code works always up
    to date
    with the code. You are always able to compare the structure of the database
    with
    your businessclasses and able to convert a wrong structure to the correct
    structure
    with maybe just a little piece of code.
    Hope this helps

  • Unicode support when round-tripping to XML

    Hi all,
    Last week, I posted a question on round-tripping the symbol font and got no replies...:-)  I'm thinking the question was entirely too generic, so I'd like to now add a little detail of what it appears are my primary options as well as current issues.
    We have a math product that requires the use of the Symbol font.  I'll use the beta here for an example: b.  I have tried several methods to get this to display in Frame properly, save to XML, and open back up into Frame, with no success, as follows:
    o Trying to enter it directly somehow into the text, either directly or as the value of a user variable, discussed below.
    o Creating an element called "symbol" that is set in the EDD to always display as a Symbol font.
      This one doesn't make it to the XML -- which complains about the document containing unsupported characters.
    You can explicitly apply this font in Frame and it displays properly, but it does not save to XML and then open back up in Frame. I thought it might, given Frame's supposed implicit Unicode support for XML (the dev and ref guides say you don't need to map anything in the rules or create any entities if you are working in XML as opposed to SGML). Further, I can see that it is defined already in the FrameMaker\Structure\isocents directory:
      <!ENTITY beta    "&#x03B2;"> <!-- GREEK SMALL LETTER BETA -->
      and also as this:
      entity "bgr" is fm char 0x62 in "FmSymbol";
      I'm not sure which is being used, but I assume my DTD does not need to define it.
    So now I have assumed that you need to enter it into Frame explicitly as a Unicode code point, but I cannot figure out how to do that. Here's what I've tried:
    Entering it directly as:
         \u03B2
    ...doesn't display a Greek beta in the regular text, although I can enter it this way into a user variable, and a Greek beta is displayed (temporary Eureka!), but only as the value of the variable in the dialog box -- not when I insert that variable into the text, which simply results in a "?".
    Using the File | Utilities | Hex Input enters only a "b" -- not a beta glyph. Although the user guide says you should be able to enter a Unicode code point with this tool, I can't see how to do that. If you manually enter the code point for the Greek symbol beta (62 for UTF-8), all you get is just that: 62.
    Using the standard Windows Character Map does enter the beta glyph in Symbol font -- but this does not round-trip.
    Entering it as "/b" -- not sure where I read about this -- doesn't display the glyph, but DOES save to XML as an entity "&sol;b". Not sure what this means, but this entity only opens back up in Frame as a "/b", not a beta glyph.
    We need to have the beta (and other symbols of course) display properly in Frame so we can print to PDF, then save to XML and reopen in Frame.  Is this possible?  Searches across all the Frame documentation have revealed nothing about how to do this, and I feel as if I'm complicated it unnecessarily, but can't tell how.
    Any ideas -- or reasonable workarounds -- would be very much appreciated.
    thanks,
    Shelley

    Shelley,
    Whether or not a unicode character displays properly is a function of the font that you are using. If you specifed the \u03B2 codepoint, then unless you're using a Pro type OTF font, chances are that the glyph simply isn't available in that font.
    Try using the Files > Utilities > Character Palette to see what's available (and also enter it by clicking on the glyphs) for the specific font that you are using in FM9. The Hex Input isn't the way to go for unicode values.
    You might also want to look at installing the Quick Unicode Input tool available at: http://www.cardbox.com/quick.htm
    [Addendum: WGL TT fonts may also contain the required greek symbols.]

  • Soundtrack pro round tripping to FCP

    Hello,
    I've been using FCP for a while now but I'm new to soundtrack Pro and working my way through the Apple Pro Training Series: Sound Editing in Final Cut Studio and soundtrack Pro. Everything is going fine and i'm getting into it - even if a bit slowly!
    However when I've tried to do the round-tripping back into FCp the file doesn't appear like it says it will after export. I've just done Lesson 3 in the book (with the same thing happening to me in lesson 2) where I have finished my edit in Soundtrack Pro and I go to export, the process bar comes up and then it takes me back to FCP and my OLD sequence but the NEW sequence doesn't appear. The book says the import XML dialog will appear but it doesn't .....
    I can import it manually by going to where I have saved the exported file but surely the whole idea of this round-tripping is to do it for you so you don't have to search for it...
    Does anyone have any ideas why this is? Is it just as simple as something is ticked or selected somewhere?
    Thanks

  • Pictures round-tripped to Elements are correct in Browser but not in Viewer

    Hi all,
    This is a bit weird.  When I edit a photo in Photoshop Elements 10 (and then "save" and thereby send it back to Aperture), the edited photo shows up correctly edited in the Aperture browser, but it's uncorrected in the viewer.  I always use the "Split View," and so the corrected photo appears among the thumbnails, but when I click on it, the photo in the viewer doesn't have the PSE corrections!  Weird.  This worked well for many many months, but now doesn't seem to work.  If I close out of Aperture and come back in, the photos are correct in the viewer and the browser.  Any ideas?  (These are correctly saved -- not "saved as" -- in Photoshop.  And it worked well for months.  No need to discuss saving and round-tripping.)  Thank you!

    Mark,
    maybe this is caused by this bug:
    Aperture 3.2.3: Viewer does not update after editing an image in external editor

  • [ot] A UML tool for a new Java project

    I am working on the new Java project and need a UML tool to get it start. I am wondering whether anyone one can recommend such tool or not. It can be either stand alone or as an Eclipse plug-in. It shall be able to handle at least 50 classes.
    Thanks.

    Is it any good? I haven't tried it but we're
    evaluating UML tools here and it's on my list to play
    with.
    PS.If you mean SDE....
    I have only used the personal edition at home, and the other versions have more functionality available
    My impressions, FWIW, are
    - easier to use than rational rose (I find this one which I have to use at work to be a pain), although, paradoxically enough, they are not that dissimilar in appearance
    - I was able to create some reasonably complex models without any problems
    - easy to install and start using - no great learning curve
    - I tried importing a model I had exported from rose and that did not work very well at all.
    - this applies to version 2.2

  • Are there any uml tools on linux ?

    I'm looking for a simple uml tool in linux.Because I'm doing my excercise from school and I want to do it in linux instead of switching to windows. And at least, it can import and export uml file from staruml.
    Thanks guys

    I'd suggest Umbrello from KDE SC. It is outstanding tool. The only issue — it is not very stable, so you should save your progress frequently.
    From it's advantages I'd like to mention
    1. UML is virtually backed by code (dunno, how to explain correctly), this is not only a graphic editor. You can create, f.ex. custom datatypes, make all possible relations, and all your actions will be then represented as graphics.
    2. It supports usecase diagrams, class, component, deployment and relation diagrams. Moreover, for the last type it can generate a valid SQL code.
    Ideally, it should generate code for class diagrams too, but the last time I used it, this feature was only declared, but not implemented. At least, for Java.
    Also there are Java ArgoUML and Violet.
    The first one is also a real UML editor and is even better than Umbrello, it has no relation diagrams, but supports flowcharts, sequence diagrams and some more.
    And the other is just a graphic editor, like DIA.

  • Trouble with Round trip between Soundtrack Pro 2 and Final Cut Pro 6

    I have edited a home movie together. I then have sent the sequence to Color for grading and then after completing the Color changes and Rendering. I sent it back to Final Cut Pro. It starts out working fine but during the transfer process it stops at somewhere between 50% and 60%. It is during the "Importing XML Data" phase. It just sits there and does not change and I have to force quit to get out of it. The exact same thing happens when I try to round trip from Soundtrack Pro 2 back to Final Cut Pro. So I am unable to make use of the changes I make in these programs.
    This is a round trip process that I have successfully made many times before. Nothing has changed. I am working in Final Cut Studio 2 with the latest updates on an Intel Mac. Any advice on how to remedy this situation would be greatly appreciated.
    Thank you in advance.

    Thanks.
    What's I've been doing is exporting the Soundtrack files as AIFF files, then importing them into Final Cut...
    It's working... at least well enough. Still seems harder then just being able to go back and forth between the two applications.
    Thanks for the advice.

  • Round trip to PS CS3 does not show the saved image in Aperture 2.1.1

    Good evening everyone; I hope someone can help me to solve this.
    I have PS CS3 set as my external photo processing app (exports are PSD 16-bit 300 dpi) in Aperture 2.1.1. When I process the picture in CS3 and then save it(mind you I only SAVE, I do not do SAVE AS) as PSD (or TIFF) Aperture only shows me the original file in preview with the little circle informing me about the round trip to CS3. So the processed file does not show. Instead I only see two identical versions of the same photo.( I mean, I see the master and the version with the little circle).
    If I save the work in PS CS3 as jpeg and then import into Aperture, it shows fine. When trying to import the processed and saved PSD and TIFF files, Aperture only shows the original file.
    If it helps, I am working on layered pictures (HDR) where I use different parts of different pictures to get wide dynamic range. I export 3 or so photos from Aperture at once to CS3, process them into one, flatten the picture and save it.
    And then Aperture just shows me the original file as version.
    I have done this before 2.1.1 and it worked. Not sure if I have changed anything that might be causing this.
    Thank you for your ideas.

    I am sure it is not stacked under the original, unfortunately. Any other tips?
    Also, as I mentioned earlier, even if I save the processed file in CS3 as PSD (so I use SAVE AS) and then try to import it into Aperture, it "magically" only shows the orginal (as if it was just importing some layer).

  • Round trip from Aperture to PS CS3 and back problem

    Hi everyone; I hope someone can help me to solve this. I posted it before but the only suggestion I got was to check if the processed photo is not stacked under, which it isn't.
    I have PS CS3 set as my external photo processing app (exports are PSD 16-bit 300 dpi) in Aperture 2.1.1. When I process the picture in CS3 and then save it(mind you I only SAVE, I do not do SAVE AS) as PSD (or TIFF) Aperture only shows me the original file in preview with the little circle informing me about the round trip to CS3. So the processed file does not show. Instead I only see two identical versions of the same photo or a layer from CS3.( I mean, I see the master and the version with the little circle).
    If I save the work in PS CS3 as jpeg and then import into Aperture, it shows fine. When trying to import the processed and saved PSD and TIFF files, Aperture only shows the original file.

    I have done this before 2.1.1 and it worked. Not sure if I have changed anything that might be causing this.
    Thank you for your ideas.

    Ernie, the photos are captured by Canon XTi so they are in CR2, saved to my internal HD and then "loaded" to Aperture as referenced files.
    As for PS CS3, I am not sure whether I have it set up as a scratch disk or not (if you could let me know where to check it).
    Yesterday, I did yet another round trip and found out that when I finish in PS and SAVE and CLOSE, then the file shows up properly in Aperture. What I was doing before was I SAVEd if but did not close. Then I would SAVE AS in PS to make sure I have some kind of a version of the file if the one in Aperture fails to work.
    So it seems I cracked it but I would still like to hear what you have to say, or anyone for that matter. It seems to me that the SAVE-CLOSE is crucial.

  • PI 7.1 Message Round Trip

    Good day,
    From rumors and small talk with fellow Netweaver technical consultants,
    I heard that with PI 7.1 - sending message without round trip  (sending message from one adapter to second adapter without entering the IS) will possible.
    1. Is that true?
    2.Where will the mapping take place if necessary?
    3.Will our monitoring capabilities will remain (message monitoring,end2end, AFW monitoring)
    If any of you experienced with PI 7.1 ,and currently not buried with development work, I'll appreciate you opinion\knowledge.

  • PPro cs6 - Audition cs6 - PPro, round trip problem

    I'm having trouble completing the round trip. I got my audio tracks from PPro CS6 to Audition CS6 without problems, right by the manual. But I'm having trouble getting that audio work back  into PPro.
    I'm working a mid-sized project (one hour class, two cameras, etc. headed for DVD). Got edit lock. Everything is done now except for cleaning up audio. After the audio I can send the whole lot to Encore for DVD making. But first, audio.
    Took the entire sequence to Audition  via PPro's  "Edit...Edit in Adobe Audition...Sequence..."  path. This worked just fine. It pushed all the audio files to Audition, Audition opened up and gave me a "make an Audition project" dialog box, etc. Nearly 100 files came over to Audition, on the right tracks, in the right order. Very nice. Made my changes. So far so good.
    What I've read in the manual says that all I have to do when I'm done is "File...Save" in Audition, then PPro will have and use the changes. Sorta like Dynamic Link, but different. So I did the the project save.
    At this point, things deviated a little from the plan. I started up PPro, opened the project, and no sign of the Audition work. Can't find a file anywhere in the project panel that says Audition on it. The files on the timeline are still the dark green of the multi-camera edit, not the lighter green of an Audition file. When I've done this for individual clips, I've gotten back a file with a name like "*Audio Extracted_1.wav" that shows up with the same green as the Audition icon on my desktop.
    So I thought, fine. Not as easy as I had hoped. I'll just have to import it manually. But PPro doesn't seem to have any idea how to deal with a *.sesx file, which is the project file from Audition.
    Should I be exporting, say, a *.wav file from Audition (how?) and import that into PPro? And if I do, is there a good workflow to re-sync this audio with my video tracks?
    I'm confused. Don't know what I did wrong. Don't know what do to fix it. Don't know how to avoid this in the future. So any help gratefully received.

    OK, now I *am* confused.
    Just did it again (a different DVD project however), as described in my original post. This time PPro stayed open for me. So I sent all the sequence audio files to Audition via the "Edit...Edit in Adobe Audition...Sequence..." comman, then did my editing in Audition, and saved it the Audition project. Go back to PPro, and... nothing. No sign of any file from Audition in the project panel. No sign on the time line. No sign of any Audition file anywhere in PPro that I can find.
    What gives? What am I doing wrong?
    What I did get was a folder at the same directory level as my PPro project file, a folder in it with the project_name I gave Auditon when it opened from the PPro  "Edit...Edit in Adobe Audition...Sequence..." command, and then two files for every clip in the project (a *.wav and a *.pkf), and finally two more files, a project_name.xml and a project_name.xml.sesx.
    I suppose I can export a *.wav file to PPro manually. Worked before. But I'd like to learn the "correct" way, the way Adobe intends it to work.
    Darned if I can figure out what I'm doing wrong though. Help???
