Well, I tried copying the model from the examples into my project, and
it failed with the following error
[andromda] INFO [AndroMDA] Input model --> 'file:/mnt/hda6/tools/BPM4StrutsExample/mda/src/uml/BPM4StrutsExample.xmi' [andromda] INFO [AndroMDA] Referenced model --> 'file:/mnt/hda6/tools/BPM4StrutsExample/mda/src/uml/andromda-profile-3.0M2-SNAPSHOT.xml.zip' [andromda] org.netbeans.lib.jmi.util.DebugException: /mnt/hda6/tools/BPM4StrutsExample/mda/src/uml/andromda-profile-3.0M2-SNAPSHOT.xml.zip (No such file or directory)

... I do not underestand why is looking for that file on that folder, are you sure you have all your libraries correctly installed?,

so I copied in the reference model and then got this error

[andromda] INFO  [AndroMDA] Referenced model -->
'file:/mnt/hda6/tools/BPM4StrutsExample/mda/src/uml/andromda-profile-3.0M2-SNAPSHOT.xml.zip'
[andromda] org.netbeans.lib.jmi.util.DebugException: Content is not
allowed in prolog.

I think I will return in a few weeks time to see if things improve.

...it is up to you!, but I started a month ago and I am already familiarized with the tool, of course at the begining takes some effords, but for sure you will find great results! :-)

...you can download the source code for the example working for the M1 release from the team server at team.andromda.org, you can see all the stereotypes and signals there.... once you know how to play arround I recomend you to download the version from the CVS and try with the new features like OCL, displaytags etc....

Carlos, could someone send me source for the bpm4struts modeling
example, I assume the html file is generated, and I will fill out the
example with more details as per my learning experience.

Hi Martin,
I had been looking the model and I think the problem is because you had market the trigger as time and it should be a signal. also you should mark the action states that will be shown as web pages with the <<FrontEndView>>

Thanks guys,
I an informative message would be much easier to diagnose than half
dozen stack traces.
Well I have been through the model which is the one in the BPM4Struts example, and all the transitions which have which have <<FrontEndEvent>> now have have a trigger(time) with a name, they didnt originally. Apart

from the transition from initial state, where MD does not give you the
option to specify a trigger. However still getting the null pointer.
Current model attached.

Many validation messages are still missing
Because running them might trigger new exceptions if you're not too
careful with the OCL
I have finished my current project within next week, after that I'll
have plenty of time to correct these kinda things (because you're
absolutely right, we need them!)

That is correct, alternatively the trigger might be missing a name
-- However shouldn't this been rendered in a validation message?

I think that you may have not set the name on a <<FrontEndEvent>> transition. Transitions should have a trigger and this trigger
must
have
a name specified within the signal.
