How to Generate a Sequence Diagram from Java Sourc

Question

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?

Answer 1

With Intellij 15.0.4: just few seconds, install the plugin SequenceDiagram (currently 1.1). Go in your in Class method that you want to analyse and Tool>SequenceDiagram :

Answer 2

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.

Answer 3

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

Answer 4

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.

Answer 5

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.

Answer 6

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:

1. [IntelliJ Community Edition IDE]

2. Code Iris for creating class diagrams and visualizing the code

3. SequenceDiagram Plugin for generating Seq Diagram on IntelliJ IDE.
