Hello all together,
i wrote an qvto transformation from BPMN to a self defined rolemodel. My first goal was to create a stand-alone transformation including a blackbox. Quickly I realized that a platform is needed to register a provider of an extension or an extensionPoint org.eclipse.m2m.qvt.oml.javaBlackboxUnits, m2m.internal.qvt.oml.blackbox.BlackboxRegistry in Platform.getExtensionRegistry().
To use a Blackbox in my transformation i created a separate eclipse application without an UI. Starting my Plugin de.test.transformation_1.0.0 via OSGi console the Transformation.class (InvokeInJava) is instantiated by Activator.class, Case (2).
Before any transformation in QVTo begins the internal TransformationExecutor load Transformation by doLoad() where the URI pointing to qvto script is checked. This leads to following Diagnostic Message: Could not find unit 'localhost/WebContent/WEB-INF/models/bpmn2roleModel.qvto'
During execution the following code is done in Interface org.eclipse.m2m.internal.qvt.oml.compiler.unitResolverFactory:
Registry INSTANCE = EMFPlugin.IS_ECLIPSE_RUNNING ? new EclipseRegistry() : new BasicRegistry();
(1) first case, the transformation is triggered by a stand-alone main class and leads to the following issues
Eclipse platform running: false, EMF.Plugin is running: false
URL is resolved
(2) The execution in own Eclipse without UI
Eclipse platform running: true, EMF.Plugin is running: true
URL is not resolved
Because no extension is found the list attribute factoryEntries in class EclipseRegistry is empty if EclipsePlatform runs.
if(EMFPlugin.IS_ECLIPSE_RUNNING) {
IExtensionRegistry pluginRegistry = Platform.getExtensionRegistry();
IExtensionPoint extensionPoint = pluginRegistry.getExtensionPoint(org.eclipse.m2m.qvt.oml.unitResolverFactory);
if(extensionPoint != null) {
IExtension[] allExtensions = extensionPoint.getExtensions(); //null
for (IExtension nextExtension : allExtensions) {
Is it really mandatory to register it's own UnitResolverFactory or could i use some oher plugins, because during the standalone Transformation via main()-method the same URL is resolved by a default http-URI resolver.
Thanks in advance for any comments
