I have a question about generating sequence diagram from Java source code. When I googled I saw someone told to use visual paradigm (VP), but it does not generate sequence diagram for me. Some steps in my VP are different from manual. The manual says to choose method but my VP does not allow to select method in a special class. Reverse Engineering Sequence Diagram from Java Source Code
Does anyone have a new idea to generate sequence diagram from Java source code?
With Intellij 2019 there are two plugins can do this job:
SequenceDiagram (currently 1.3).
Go in your in Class method that you want to analyse and Tool>SequenceDiagram :
ZenUML support (currently 2019.1.2)
If you are using or wish to use the Eclipse IDE then you can install the ObjectAid UML plugin that can reverse engineer from:
Java Stack Trace Console
Java Stack Frames from Debug View
Methods Call from Call Hierarchy View
and MUCH more.
See http://www.objectaid.com/sequence-diagram
I have implemented a junit test based sequence generator which generates sequence diagrams for the pgf-umlsd latex package example:
Hello world
#Test
#SequenceDiagram({ Controller.class, Model.class })
public void testMethod() {
Controller c = new Controller(new Model());
c.init();
c.simpleBeanOperation();
}

try this tool, This tool helps you to create the Java source code to Sequence and class diagram, including the execution time of each flow.
follow the steps as given in the documentation
http://maintainj.com/
UML-VP could generate sequence diagrams, pretty well. Based on your description, I feel you chose the package directory for presenting the source files to the tool. I have faced similar problem. The solution is to choose the "src" folder above the package folder, and then you can see some pretty nice diagrams flying out. Good Luck.
I used Umlgraph which is free see http://www.umlgraph.org/
But I mostly use it to generate class diagram in Javadoc.
To generate sequence diagram, you have to write many lines in your source file.
See http://www.umlgraph.org/doc/dns.html.
You will have to install Graphviz to make it work.
Another good tool that generates sequence diagrams from Java programs is JIVE: www.cse.buffalo.edu/jive
It is available as a plug-in for Eclipse and is a free download. Also supports visualization of multi-threaded Java programs.
Note: JIVE generates the diagram for the execution of the program. It also generates object diagrams, and has other useful features such as query-based debugging. Sorry if this is not what you had in mind.
I tried a lot of options today to generate Sequence and class diagrams from my existing code using IntelliJ Idea community edition, Below is the Solution which worked for me finally:
Specific versions of Intellij community edition only was compatible with the required plugins to make this work.
so its very important to download the right versions of IDE and plugins to make it work.
Here are the links to the complete set of softwares with specific versions which worked for me, pls note i tested these on my Mac Book Pro:
[IntelliJ Community Edition IDE]
Code Iris for creating class diagrams and visualizing the code
SequenceDiagram Plugin for generating Seq Diagram on IntelliJ
IDE.
There are many products that can generate sequence diagrams from Java source code. Unfortunately, all of the good ones cost a lot of money.
If you are using the community edition of Visual Paradigm, it does not allow you to generate any diagrams. You must upgrade to one of the paid versions.
You can compare the paid vs the free edition here
http://www.visual-paradigm.com/product/vpuml/features/?edition=ce
You need to buy standard edition of Visual Paradigm that support Code engineering.
Check out some of these links for alternative programs which also can generate diagrams / source code.

How can I generate sequence diagrams from Java source code?
Sequence Diagram Reverse Engineering
http://www.altova.com/umodel/sequence-diagrams.html
The unable to select operation when performing reverse engineering of Java source code to sequence diagram in VP probably caused by selecting the wrong source folder. As long as you select the root folder of your source (according to the "package" statement of your class) it should then works. BTW, Visual Paradigm offer the subscription license which allow user to subscribe the license in monthly basis and in a relative low cost.
Does such program exist?
I have to study Java SE and diagram with all classes and interfaces from given package will be immensely helpful.
For example I want to plot all relations between subclasses of types Collection and Map.
I know there are a lot of images with core package structure already, but don't really trust them because they are proven to be incomplete, outdated or even inaccurate.
Whilst I don't know of any tools for generating UML class diagrams from JavaDocs, there are many tools available that can generate UML class diagrams from source code, and there are already many questions on StackOverflow that suggest various tools that can do this
This question seems to have a good range of options that you could explore. I've used ArgoUML myself, but I suggest looking at the options to find the one what appeals to you most.
You can download the Java SE source code and generate the class diagrams for the sections you're interested in.
You can create RCP application using ZEST. This is pretty cool
You can not create diagrams from JavaDoc because there is no official implementation. Only Java code could be reversed and displayed as class or sequence diagrams.
I played to reverse the full Java language with EclipseUML Omondo. It was really interesting to get all dependencies, inheritances, associations at package but also at project level, or even at multi-projects level.
The trick Omondo use is to convert manually each Java Id to a single UML Id. You get after a 30 mn process a huge model composed by hundred of thousands UML Ids saved in an XMI format respecting java project structure. I mean you get project > packages > class> iner classes > attrbites etc...
From this model then you create views by drag and drop or directly selecting the entire package. You can show hide relations, navigate in the code at graphical level etc.....
Really amazing technology !!
I'm in the need of a eclipse plugin / or tool which can generate
class diagrams from my java/groovy code and vice versa. Actually it is a
groovy/grails project. The actual requirements are:
I should be able to draw class diagram and generate code and generate class diagram
from existing code
(Important) I have to export the generated class diagram in some format to share it
with my teammates, so they can generate code from it.
Please suggest me a good solution.
Thanks in advance.
You can use visual paradigm for uml. Using Visual Paradign you generate UML diagrams of your and generate code, using UML diagrams
You can create diagrams, share it on CVS or by email but it is only possible with the java code. I don't think it exist for both groovy and java.
You have two options today which is to use a live code and model synchronization tool which is more integration level or a model driven tool which will generate all the code once the model has been completed.
I personally prefer the first live synchronization option because if the code is updated then my model will also be. It is painful to produce diagrams and then realize that at the implementation stage the development team has changed the code and that my diagrams are not anymore relevant !!
Is there a way to get reversed engineered uml diagrams into Omnigraffle?
I got a bunch of eclipse plugins that can create UML class diagrams, but not in a format that Omnigraffle can handle.
Is there any way to get my project from eclipse to Omnigraflle?
Thanks!
I've created a little plugin for Eclipse in order to create an OmniGraffle UML-like class diagram from a Java package. It does not create files, but instead uses AppleScript to direcly draw the diagram in an opened OmniGraffle drawing. The plugin provides some options in order to control the diagram creation, e.g., show or hide private attributes etc. Parameterized collections are transformed into associations, however there is room for improvement. The plugin is described at
http://jpilgrim.github.com/eclipsetools/j2og/
where you will also find a link to the update site in order to easily install the plugin.
Yes, this is strange but no XMI export to Omnigraffe is available from UML 2.3.
I don't think this is a big job to be done so you can do it by yourself. You need to take the EclipseUML2 metamodel or the EMF model then manually identify each model element (e.g a class in UML 2.3 is .....in Omnigraffe, etc....)
Once all the elements have been identify then code a xml mapper. It would work.
A good mapper is about 18 months work for one engineer, but if you are 5 of you you can do it in less than 3-6 months (2months for codding and 4 months for testing).
Good luck for this potential project.
My question could be why the Omni Group has not done the xml export ?
How can I generate UML diagrams (especially sequence diagrams) from existing Java code?
ObjectAid UML Explorer
Is what I used. It is easily installed from the repository:
Name: ObjectAid UML Explorer
Location: http://www.objectaid.com/update/current
And produces quite nice UML diagrams:
Description from the website:
The ObjectAid UML Explorer is different from other UML tools. It uses
the UML notation to show a graphical representation of existing code
that is as accurate and up-to-date as your text editor, while being
very easy to use. Several unique features make this possible:
Your source code and libraries are the model that is displayed, they are not reverse engineered into a different format.
If you update your code in Eclipse, your diagram is updated as well; there is no need to reverse engineer source code.
Refactoring updates your diagram as well as your source code. When you rename a field or move a class, your diagram simply reflects the
changes without going out of sync.
All diagrams in your Eclipse workspace are updated with refactoring changes as appropriate. If necessary, they are checked out of your
version control system.
Diagrams are fully integrated into the Eclipse IDE. You can drag Java classes from any other view onto the diagram, and diagram-related
information is shown in other views wherever applicable.
EDIT:
If you're a designer then Papyrus is your best choice it's very advanced and full of features, but if you just want to sketch out some UML diagrams and easy installation then ObjectAid is pretty cool and it doesn't require any plugins I just installed it over Eclipse-Java EE and works great !.
UPDATE Oct 11th, 2013
My original post was in June 2012 a lot of things have changed many tools has grown and others didn't. Since I'm going back to do some modeling and also getting some replies to the post I decided to install papyrus again and will investigate other possible UML modeling solutions again. UML generation (with synchronization feature) is really important not to software designer but to the average developer.
I wish papyrus had straightforward way to Reverse Engineer classes into UML class diagram and It would be super cool if that reverse engineering had a synchronization feature, but unfortunately papyrus project is full of features and I think developers there have already much at hand since also many actions you do over papyrus might not give you any response and just nothing happens but that's out of this question scope anyway.
The Answer (Oct 11th, 2013)
Tools
Download Papyrus
Go to Help -> Install New Software...
In the Work with: drop-down, select --All Available Sites--
In the filter, type in Papyrus
After installation finishes restart Eclipse
Repeat steps 1-3 and this time, install Modisco
Steps
In your java project (assume it's called MyProject) create a folder e.g UML
Right click over the project name -> Discovery -> Discoverer -> Discover Java and inventory model from java project, a file called MyProject_kdm.xmi will be generated.
Right click project name file --> new --> papyrus model -> and call it MyProject.
Move the three generated files MyProject.di , MyProject.notation, MyProject.uml to the UML folder
Right click on MyProject_kdm.xmi -> Discovery -> Discoverer -> Discover UML model from KDM code again you'll get a property dialog set the serialization prop to TRUE to generate a file named MyProject.uml
Move generated MyProject.uml which was generated at root, to UML folder, Eclipse will ask you If you wanted to replace it click yes. What we did in here was that we replaced an empty model with a generated one.
ALT+W -> show view -> papyrus -> model explorer
In that view, you'll find your classes like in the picture
In the view Right click root model -> New diagram
Then start grabbing classes to the diagram from the view
Some features
To show the class elements (variables, functions etc) Right click on any class -> Filters -> show/hide contents Voila !!
You can have default friendly color settings from Window -> pereferences -> papyrus -> class diagram
one very important setting is Arrange when you drop the classes they get a cramped right click on any empty space at a class diagram and click Arrange All
Arrows in the model explorer view can be grabbed to the diagram to show generalization, realization etc
After all of that your settings will show diagrams like
Synchronization isn't available as far as I know you'll need to manually import any new classes.
That's all, And don't buy commercial products unless you really need it, papyrus is actually great and sophisticated instead donate or something.
Disclaimer: I've no relation to the papyrus people, in fact, I didn't like papyrus at first until I did lots of research and experienced it with some patience. And will get back to this post again when I try other free tools.
What is your codebase? Java or C++?
eUML2 for Java is a powerful UML modeler designed for Java developper
in Eclipse. The free edition can be used for commercial use. It
supports the following features:
CVS and Team Support
Designed for large project with multiple and customizable model views
Helios Compliant
Real-time code/model synchronization
UML2.1 compliant and support of OMG XMI
JDK 1.4 and 1.5 support
The commercial edition provides:
Advanced reversed engineering
Powerful true dependency analyze tools
UML Profile and MDD
Database tools
Customizable template support
I am one of the authors, so the answer can be biased. It is open-source (Apache 2.0), but the plugin is not free. You don't have to pay (obviously) if you clone and build it locally.
On Intellij IDEA, ZenUML can generate sequence diagram from Java code.
Check it out at https://plugins.jetbrains.com/plugin/12437-zenuml-support
Source code: https://github.com/ZenUml/jetbrains-zenuml
How about PlantUML?
It's not for reverse engineering!!! It's for engineering before you code.
I developed a maven plugin that can both, be run from CLI as a plugin goal, or import as dependency and programmatically use the parser, #see Main#main() to get the idea on how.
It renders PlantUML src code of desired packages recursively that you can edit manually if needed (hopefully you won't). Then, by pasting the code in the plantUML page, or by downloading plant's jar you can render the UML diagram as a png image.
Check it out here https://github.com/juanmf/Java2PlantUML
Example output diagram:
Any contribution is more than welcome. It has a set of filters that customize output but I didn't expose these yet in the plugin CLI params.
It's important to note that it's not limited to your *.java files, it can render UML diagrams src from you maven dependencies as well. This is very handy to understand libraries you depend on. It actually inspects compiled classes with reflection so no source needed
Be the 1st to star it at GitHub :P
I would recommend EclipseUML from Omondo for general usage, although I did experience some problems a few months back, with my web projects. They had a free edition at one point in time, but that is supposedly no longer promoted.
If you are really keen on reverse engineering sequence diagrams from source code, I would recommend jTracert.
As far as Eclipse projects themselves are concerned, the Eclipse UML2 Tools project might support reverse engineering, although I've have never seen its use in practice.
The MoDisco (Model Discovery) project Eclipse GMT project seems to be clearer in achieving your objective. The list of technology specific tools would be a good place to start with.
I found Green plugin very simple to use and to generate class diagram from source code.
Give it a try :).
Just copy the plugin to your plugin dir.
Using IntelliJ IDEA. To generate class diagram select package and press Ctrl + Alt + U:
By default, it displays only class names and not all dependencies. To change it: right click -> Show Categories... and Show dependencies:
To genarate dependencies diagram (UML Deployment diagram) and you use maven go View -> Tool Windows -> Maven Projects and press Ctrl + Alt + U:
The result:
Also it is possible to generate more others diagrams. See documentation.
You could also give the netbeans UML modeller a try. I have used it to generate javacode that I used in my eclipse projects. You can even import eclipse projects in netbeans and keep the eclipse settings synced with the netbeans project settings.
I tried several UML modellers for eclipse and wasn't satisfied with them. They were either unstable, complicated or just plain ugly. ;-)
You can use the 30 days evaluation build of EclipseUML for Eclipse 3.5 : http://www.uml2.org/eclipse-java-galileo-SR2-win32_eclipseUML2.2_package_may2010.zip
This is not the latest 3.6 build, but is pretty good and don't require you purchase it for testing and reverse engineering.

EclipseUML Omondo is the best tool in the world for Java. Only eUML seems to compete with it on this live java synchronization market, but eUML adds model tags in the code which is really very very bad and a definitive no go for me.
I've noticed SequenceDiagram plugin for Intellij is also a good option.
By far the best tool I have used for reverse engineering, and round tripping java -> UML is Borland's Together. It is based on Eclipse (not just a single plugin) and really works well.
Another modelling tool for Java is (my) website GitUML.
Generate UML diagrams from Java or Python code stored in GitHub repositories.
One key idea with GitUML is to address one of the problems with "documentation": that diagrams are always out of date. With GitUML, diagrams automatically update when you push code using git.
Browse through community UML diagrams, there are some Java design patterns there. Surf through popular GitHub repositories and visualise the architectures and patterns in them.
Create diagrams using point and click. There is no drag drop editor, just click on the classes in the repository tree that you want to visualise:
The underlying technology is PlantUML based, which means you can refine your diagrams with additional PlantUML markup.
There is a Free tool named binarydoc which can generate UML Sequence Diagram, or Control Flow Graph (CFG) from the bytecode (instead of source code) of a Java method.
Here is an sample diagram binarydoc generated for the java method java.net.AbstractPlainSocketImpl.getInputStream:
Control Flow Graph of method java.net.AbstractPlainSocketImpl.getInputStream:
UML Sequence Diagram of method java.net.AbstractPlainSocketImpl.getInputStream:
I suggest PlantUML. this tools is very usefull and easy to use. PlantUML have a plugin for Netbeans that you can create UML diagram from your java code.
you can install PlantUML plugin in the netbeans by this method:
Netbeans Menu -> Tools -> Plugin
Now select Available Plugins and then find PlantUML and install it.
