Yes, in previous post I've used it as "platform:/plugin/org.eclipse.uml2.uml/model/UML.genmodel", but AFAIK MWE does not use Equinox/OSGi runtime and "plugin" URIs are not recognized.

Krzysztof,

Normally platform:/plugin// does the trick, at least in an Equinox runtime.

absolute path would make a problem in team environment, is there any ${property} or a way to get the absolute path to a plugin on runtime?

I actually did not have time yet to play with Xtext (the end of studies), but it look great :)

Sven,

EMF can even deal with accessing deeply nested jars:

A connection that can access an entry in an archive, and then recursively an entry in that archive, and so on. For example, it can be used just like jar: or zip:, only the archive paths can repeat, e.g.,
  archive:file:///c:/temp/example.zip!/org/example/nested.zip!/org/example/deeply-nested.html
  
The general recursive pattern is
  archive:$nestedURL${/!$archivePath$}+
  
So the nested URL for the example above is
  file:///c:/temp/example.zip
  
Since the nested URL may itself contain archive schemes, the subsequence of the archive paths that should be associated with the nested URL is determined by finding the nth archive separator, i.e., the nth !/, where n is the number of ":"s before the first "/" of the nested URL, i.e., the number of nested schemes. For example, for a more complex case where the nested URL is itself an archive-based scheme, e.g.,
  archive:jar:file:///c:/temp/example.zip!/org/example/nested.zip!/org/example/deeply-nested.html
  
the nested URL is correctly parsed to skip to the second archive separator as jar:file:///c:/temp/example.zip!/org/example/nested.zip

Don't copy the genmodel but use a file URI which points to the genmodel in the jar.
Don't know the exact syntax, but I guess you'll find it by looking into the code and JavaDocs of EMF's URI class.

It's something like this as I remember:

file:/my/absolute/path/org.eclipse.uml2.uml.jar!/model/UML.genmodel

Hi Krzysztof,

my previous post has been submitted to fast. Actually a platform:/plugin uri will not help you, because the workflow does not know about registered plugins etc.

I know that unfortunately. In xtext we have:

import "http://www.eclipse.org/uml2/3.0.0/UML"

and in workflow we have:

platformUri="${runtimeProject}/.."
>

...
class="org.eclipse.xtext.generator.ecore.EcoreGeneratorFragment"
genModels="platform:/resource/myproject/UML.genmodel"
/>

and I got a feeling that something is bad here :(

As I understand this is an osgi/ eclipse plugins stuff that workflow ignores. In active workbench, uri: "http://www.eclipse.org/uml2/3.0.0/UML" allow to find both the genmodel and the epackage. Maybe there is a way to dump registered metamodels and make them visible to the workflow? Or handle the "platform:/plugin" uri somehow? Model and genmodel should be visible to workflow without copying as they are already on classpath.

Krzysztof Kowalczyk

By the way, I managed to resolve the need for the notation.ecore. I
misread the GMF book and interpreted it that I must have
firstElementOnly=false if I have multiple roots in my file. Obviously
I don't want to parse diag info so if I remove this flag (default=true)
I remove the need to deal with notation.ecore.

I'm still getting a termination from an exception with no error message associated with it when running in debugger (occasional memory violation with f5)

I'm trying a bit of refactoring to see if it helps

regards
Steve

PS thanks for the great info

Sorry to answer my own post, hopefully someone may find it useful in
future!
The reason for the error below was that I was was linking by reference
to uml.ecore and ecore.ecore and some attributes were badly set as uml
definition of string as opposed to ecore string. A quick edit of the
attribute type in the local ecore fixed that problem as a workaround.
There were some other later issues with other namespaces not being found so I just added them via multiple calls of RegisterEcoreFile.
However, since this is a mixed model and diagram file containing both
model and GMF diagram info the workflow is now looking for
Package with uri 'http://www.eclipse.org/gmf/runtime/1.0.2/notation' not found
as this is referenced in the gmf output file default2.ngoss
Haven't worked out this one yet , any hints?

To clarify, TestModel referred to below is a string value defined by my ecore files as a legal String, it was created by my GMF-EMF editor so I would be surprised if it weren't legal. Hence my question as to what Reader I should use?

Hi Bill,
sorry, I've no idea why the workflow terminates silently. It seems that for some yet unkown reason the exception is not printed on the console. Did you try the debug mode (don't forget to flag the "Java Debug" checkbox in the run configuration) in order to find out where, when and why it terminates?
Sorry, I couldn't help more.

Hi
I originally posted to the tmf newsgroup but I suspect I should have posted here? I have been experimenting further and this post is updated

I have created a GMF editor based on multiple linked ecore files and my GMF editor creates a shared EMF-GMF editor domain in a single file.

I have set up an action to call a workflow from my GMF UI and it appears to be configured correctly but doesn't actually produce anything. (ie it's called from java using WorkFlowRunner().... The intention is to call the workflow on my editor's model files which will be in their own project directory.

As part of my testing I'm manually testing by running the workflow from the project explorer (right click run as MWE). I have set up a runtime config but when I run I get no errors and no output. I get a message 'terminated' on top of the console window.

I am also seeing a lot of messages "Could not acquire children from extension: com.xx.dsl.yyy.diagram.resourceContent" in the error log but these don't seem to timed with my test runs so I'm not sure if they are related.
this is my workflow is as follows (running on OS X 10.5.7)
    
        
        
        
    
My test xpt file is in com.xx.yy.ui/templates/Demo.xpt
I have put a copy set of my model ecore files in com.xx.yy.ui/model/ (contract.ecore etc) and I have put a test copy of the GMF editor model output default2.ngoss in /templates
(once I get this running manually I'll be using a call from java)
When I run the workflow it gets as far as and stops

Hi Krzysztof,
my previous post has been submitted to fast. Actually a platform:/plugin uri will not help you, because the workflow does not know about registered plugins etc.

I know that unfortunately. In xtext we have:

import "http://www.eclipse.org/uml2/3.0.0/UML";

and in workflow we have:

...

and I got a feeling that something is bad here :(

As I understand this is an osgi/ eclipse plugins stuff that workflow ignores. In active workbench, uri: "http://www.eclipse.org/uml2/3.0.0/UML"; allow to find both the genmodel and the epackage. Maybe there is a way to dump registered metamodels and make them visible to the workflow? Or handle the "platform:/plugin" uri somehow? Model and genmodel should be visible to workflow without copying as they are already on classpath.

Krzysztof Kowalczyk

Hi Krzysztof,

my previous post has been submitted to fast. Actually a platform:/plugin uri will not help you, because the workflow does not know about registered plugins etc.

I didn't find another solution than you. It seems you really have to be evil and copy the genmodel. Maybe somebody else knows the trick how to avoid this?

Don't do that, some projects does include changes in code generated
from ecore models. AFAIK UML project is one of them so you should use
generated code not the dynamic version IMHO. Unfortunately UML need
different handling in most cases (its own metamodel, its own setup etc.)

What you need is to register the generated UML model by registering the
generated EPackage:

You also need small change like that in your Xtext workflow:

But actually this will not work (I never liked uri), can somebody
correct that? Is the copying genmodel and using "platform:/resource/"
instead, the only solution? It works, but is pure evil IMO ;)

Is it a typo in your post: the uri to installed plugins should be
platform:/plugin/org.eclipse.uml2.uml/...

instead of platform:/plugin_s_.
