Hi,

Can anyone recommend a tool that reverse engineers UML class diagrams
from Java code and presents the class diagram as a .uml file.

Thanks,

Jacqui

Hi Jacqui,

IBM has a "visualizer" feature in RSx that will create diagrams from Java
code and uses the .uml format for semantics. It's not a freebie however
:(

Cheers,

Look at topcased.org, it contains a UML modeler and a java to uml importer.

Hi,

for compiled Java you could try:
http://ssel.vub.ac.be/ssel/research:mdd:jar2uml
It is no graphical editor, it just produces the .uml model. But you can
create a diagram from those with any MDT-UML compatible editor.

Hi Jacqui,

You can either use EclipseUML Free Edition for Eclipse 3.3 (download
available at: http://www.ejb3.org/download_free_eclipse_3.3.html ) and get
class diagrams and a UML 2.1 model file .uml or use EclipseUML 2008 Studio
Edition 30 days evaluation for Eclipse 3.4 ganymede (download available
at: http://www.ejb3.org/download_studio_eclipse_3.4.html).

EclipseUML free or Studio editions are certainly the most advanced Java
reverse engineering tool on the market.
I have written few tutorials on this subjects.
1. How to reverse a java project using EclipseUML (3 minutes flash
tutorial) http://www.ejb3.org/reverse.swf
2. Why EclipseUML is the best :
http://www.tutorial-omondo.com/reverse/index.html
3. Log4j reverse HTML documentation (this is my 2003 tutorial, but it is
still Ok for reverse :-) available at:
http://www.tutorial-omondo.com/log4j/index.html

This is my penny. Hope it helps !!

Hi Jacqui,

I have written a short beginner level document on how to reverse jar files
available at: http://www.ejb3.org/jar_file_reverse/jar_file_reverse.html
Omondo have introduced this new concept giving legacy jar files the
possibility to be reversed, visualized, dynamically navigated and merged
inside an existing modeling project.

Let's have a look at a possible use. For example if you want to extend
Spring classes for a customized message customer. You then need to
understand Spring JMS classes. The problem is that Spring distribution
comes as big libraries.
The easiest way to see how to customized Spring extensions is therefore to
reverse it.

Vlad,

Dear friends,

We have updated our product documentation and have added a reverse
engineering example available at:
http://www.forum-omondo.com/documentation_eclipseuml_2008/re verse/reverse/reverse_engineering_example.html

We have added or three new features:

- XMI Backup of all your java project information :
http://www.forum-omondo.com/documentation_eclipseuml_2008/re verse/reverse/index.html#1.1_Create_a_detailled_model_includ ing

- Model Merge which merge existing model with modified java code. The
merge option is an important stage if the java project is evolving with
the creation of new UML diagrams :
http://www.forum-omondo.com/documentation_eclipseuml_2008/re verse/reverse/index.html#1.3_Merge_existing_model_with_modif ied

- JPA Annotations reverse

- The sequence diagram has been entirely redone. Sequence diagram reverse
documentation is available at:
http://www.forum-omondo.com/documentation_eclipseuml_2008/re verse/reverse/index.html#4._Sequence_Diagram_Reverse_Enginee ring

My favorite feature could seem to be stupid bwt I like it :-)
You can reverse a java project then just delete your java code from your
project. The full project mapping from Java to UML allows you to navigate
inside Java without java by just using the model. A good way to use this
feature is to reverse a java project. If you want to keep your existing
project safe you just paste and copy the model at the root of your java
project and then can navigate freely with no change in your java. This is
really cool !! Once the code has changed then your merge your model again
and again as many times as needed.
The Java reverse without java documentation is available at:
http://www.forum-omondo.com/documentation_eclipseuml_2008/re verse/reverse/reverse_engineering_example.html#7._Erase_your _java_code_manually_and

Don't forget that Omondo reverse use the same model as other compatible
tools such as Eclipse Modeling or RSA or others. Don't also forget that
you can paste and copy RSA inside an Eclipse 3.4 and recreate your model
using EclipseUML :
http://www.forum-omondo.com/documentation_eclipseuml_2008/ec lipseuml2008_dynamic_navigation.html#5._Model_interchange_wi ht_RSA_7

From this stage the reverse is not based on Java but on the model if you
recreate view from your models.
This my penny to this forum.

There is also coffea.sourceforge.net which is in alpha stage and allows
you to reverse engineer a class diagram from source code and also to
browse the source code through a class diagram...

The only problem currently is the use with big projects : with more than
hundred files with this plugin it is safer to reverse engineer not the
whole project but package after package.

Hope this can help,

This is funny. I was reading this post this morning and realized that the
Log4J reverse engineering example has been written six years ago. whaoo !!

My return of experience is that we have needed 7 years to make this
reverse usable.
Two years of research to create the core which was developed by Yves Yang.
One year to get first customer feedbacks.
18 months to fix UML 2 and JDK 6 upgarde (developped by Brahim Lookhil).
one year to get second return of experience.
18 months to add JDK 6 annotations, associations detections, mapping to
UML 2.2, merge and make this reverse wonderful and iterative(developped by
Bacem Souissi).

Thanks to all these members (all others who helped our architects) who are
not anymore working for Omondo but who have created this incredible
reverse.
