[Carlos Scheidecker]

Hello,

I am trying to generate UML2 models from code using the drag and drop feature.

It works, but when the code (class) is too big I have issues with it.

I’ve tried to increase the heap memory to 8GB and I still have the
same issues with that part of the code that is big.

I’ve googled and I saw some people with the same errors with the JFace
plugin. Still I could not solve it.

Here’s the error stack for it:

eclipse.buildId=unknown
java.version=1.6.0_13
java.vendor=Sun Microsystems Inc.
BootLoader constants: OS=linux, ARCH=x86_64, WS=gtk, NL=en_US
Command-line arguments: -os linux -ws gtk -arch x86_64

scheidecker,

Sorry that you ran into this issue.

Can you give some more information to understand the issue better ?

1) Can you share your build id from Help > About MyEclipse Enterprise Workbench > Build id? Paste it here.

2) How big is your class file ?

3) Alternatively I suggest you use the UML2 Reverse Engineering feature for generating the UML2 diagrams from code. Right click on the project > MyEclipse > UML Class Diagram from Java.

Please check this link on the same : http://www.myeclipseide.com/documentation/quickstarts/uml2_overview/

Let me know how this works for you.

[Carlos Scheidecker]

Swapna,

1) Build id: Version: 9.0
Build id: 9.0-20110318

2) The class file has 12.000 lines and was generated by a lexer. It has many variables. There are 2 of these files.

Thanks.

Swapna,

MyEclipse 9 menus and interface for UML 2 is quite different than the one on the instructions. For once, I do not have the menu MyEclipse > UML Class Diagram from Java. Tried switching perspectives, right clicking on the UML2 item and nothing. The only I was able to find out how to reverse engineer it was by dragging the source folder and then it crashes.

scheidecker,

Switch to MyEclipse UML2 perspective.Right click on the project > MyEclipse > Generate UML2 class diagram.
Attached is the screenshot for your reference.

scheidecker,
I think the context menu action has been changed to “Generate UML2 Class diagram”. You will find it in the MyEclipse context menu (Select project->Right click->MyEclipse-> Generate UML2 Class Diagram…). I have used it on larger projects (similar to one you have) and Class diagram generation works pretty well.

Regards,
NB
