I just installed Eclipse 2.1 and Eclipse UML 1.2.1.20030417 from the jar autoinstaller on my Gentoo Linux system using the Sun 1.4.1 jvm. I'm trying to follow the tutorial "Creating an EMF Model using a Graphical Editor" but am getting stuck at the start.

I go into the library/src/model and select New->Other from the context menu. This pops up a wizard somewhat different from the one in the tutorial -- the left options include "EMF Diagrams" and "UML Diagrams" instead of "UML". OK, that's probably the result of a newer version...

I select "EMF Diagrams" and "EMF Class Diagram" and click the highlighted Next button. An Eclipse UML splash screen pops up and goes away and I'm looking at the same wizard page with my selections and a highlighted Next button which I can click as often as I want but nothing happens.

Is there some basic configuration/install mistake I've made?

I got the same problem as listen below... and that trace:

D:\toto\eclipse>

any ideas?????

[xavier]

Are you sure that you have installed the Eclipse 2.1 final release ?

Typically the missing Eclipse class is that kind of behaviour.

Regards.

[dlpierson]

I just download and built it last week. It says 2.1, as
did the links I followed.

Thanks the previous reply I managed to find the workspace error log. Here's the last stack trace.

[BlueBus]

Same here, did anybody manage to start the tool ?

[jonny]

Hello Bluebus,

I think that thousands of users succeeded to install EclipseUML.
EMF changed and Omondo is still up to date. Great job

I got the same problem using Eclipse 2.1 Final and EclipseUML 1.2.1
This error occurs only if you try to create an uml diagram in a simple project. Use a Java project instead and everything works fine.

Hope this helps!

[ajkret]

I think I discovered the cause.

First, my environment:

-Windows 2000;
-Eclipse 2.1 MD5
-EclipseUML 1.2.1

The log file:

Then I install de Eclipse 2.1 version NOT MD5 and the problem has gone. That class mentioned, org/eclipse/ui/ISaveablePart, is not part of the workbench.jar from the eclipse\plugins\org.eclipse.ui.workbench_2.1.0 directory.
