Ok. I started again from scratch, and I think that maybe I know where is the problem, but no idea which is the solution.
In my case, I'm developping plugins, which contains the definition of the metamodel, and the plugins required to get the workflow and run. I run this eclipse application, and in the new eclipse window I define the worflow file (.mwe) and the .xpt file. I think that maybe is a problem with the classpath, since if my plugins and source code are in the first Eclipse application, in this second one, where I have the xpt and mwe file, maybe it cannot find the projects and the path to get to that files. In this sense, If I define a new plugin project inside this second eclipse application, the workflow runs without problems and I get the files.
Could be this an explanation? If this is the case, how can I do this?
I copy and paste again the workflow file, the expand file, the error, and the source code where I call to the workflowrunner. So, for clarifying, I developped
the metamodel, then I run it as a new Eclipse application (let's say window 2), and in window2 I create a new project where I have the workflow file
and the xpand file. And then, I have a button that I press in order to call Workflowrunner internally.
Workflow source code:
<?xml version="1.0"?>
<workflow>
<!-- load model and store it in slot 'model' -->
<component class="org.eclipse.emf.mwe.utils.Reader">
<uri value="${model}" />
<modelSlot value="model" />
<firstElementOnly value="true"/>
</component>
<component id="generator" class="org.eclipse.xpand2.Generator">
<metaModel id="mm" class="org.eclipse.xtend.typesystem.emf.EmfMetaModel">
<metaModelPackage value="myproject.zz.ZzPackage"/>
</metaModel>
<expand value="MyExample::myfc::main FOR model"/>
<outlet path="${outputFolder}/" />
</component>
</workflow>
Xpand file:
«IMPORT zz»
«DEFINE main FOR ZModel»
«FILE "hello.txt"»
hello
«ENDFILE»
«ENDDEFINE»

The "providing plug-in" (in your first Eclipse instance) needs to have the
model path in the exported classpath entries. The consuming plug-ins must
declare a dependency on the providing plug-in. The consuming plug-in does not
necessarily have to be a plug-in project in the PDE sense. Example: I'm
working on an editor/generator application that uses EMF files and calls the
generator transparently (without creating a plug-in project at runtime) to
create some output. But in this case, the "model plug-in" has to put the
models into its exported class path and the "generator plug-in" has to depend
on the model plug-in. Have you checked this?

Could you perhaps outline the directory structure (absolute paths to model and
XPand files)?

Hi,
I tried to add to the classpath, as you suggested, in the plugin definition of classpath in runtime the model, I copy all the model files into a folder
and then I just add this folder to the classpath in the runtime of the plugin, but I still get the same error.
It fails in this point
File: ExpandStatement.class
private void invokeDefinition(final String defName, final Object targetObj, final Object[] params, final Type[] paramTypes,
XpandExecutionContext ctx) {
final Type t = ctx.getType(targetObj);
final XpandDefinition def = ctx.findDefinition(defName, t, paramTypes);
--------
The return value of def is null. And in t_name is zz::ZModel
The outline of the folder structure is the following:
Absolute path:
E:/Migration-Galileo/Workspaces/runtime-EclipseApplication/M yExample/MyExample.zz
E:/Migration-Galileo/Workspaces/runtime-EclipseApplication/M yExample/outpu/mywkf.mwe
E:/Migration-Galileo/Workspaces/runtime-EclipseApplication/M yExample/myfc.xpt
Relative path:
Name_of_the_project/Name_of_the_file
MyExample/MyExample.zz
MyExample/mywkf.mwe
MyExample/myfc.xpt
I press a button that must call internally and load the workflowrunner in order to read the
workflow, and execute it.
And the error is again the same:
GRAVE: Error in Component generator of type
org.eclipse.xpand2.Generator: EvaluationException : No Definition
'MyExample::myfc::main for zz::ZModel' found!
[23,38] on line 1 'EXPAND MyExample::myfc::main FOR model'
And I do not why, but now I cannot see the output error in the standard output and neither in the error console
Is there any console that I can use to see the errors, instead of using the debug mode and looking with breakpoints?
Thank you !

Hi Carmen,
please tell us where all the resource are located.
There are lot of different possibilities to start a workflow.
It seems that you're starting it from within a running bundle in Eclipse
but expect to have things from your workspace visible.

Hi,
I tried the thing of the paths in the workfile and it is not the problem. And yes, my plugin is calling the workflow that is in the new project of the "new workspace" (not in the generator plugin) and in that project it is also the xpt file.
I found this entry in the oaw official webpage
http://www.openarchitectureware.org/article.php/howto_cartri dge_as_plugin
And there is a part that is exactly my problem:" Accessing resources from projects in the workspace"
My plugin needs to access/load the project in the workspace project from my plugin??. I guess that I need to define my own class loader in the same way, do I? Is the information there still valid for the new version of oaw, or do I have any other way of doing this?
Thanks a lot!
