I have a grammar (Ytext based on Xbase) and a model.
In the model-File I can create my model
In the model I have created the folder src-gen.
My Problem is:
When I save my Modelfile, there is no java-File in the src-gen folder

I send you a picture of my model.

My grammar is
grammar org.lunifera.metamodel.dsl.entity.Entity with org.eclipse.xtext.xbase.Xbase

generate entity "http://www.lunifera.org/metamodel/dsl/entity/Entity"

DomainModel:
	elements+=AbstractElement*;

AbstractElement:
	PackageDeclaration | Entity | Import;

PackageDeclaration:
	'package' name=QualifiedName elements+=AbstractElement* ';'	;

Import:
	'import' importedNamespace=QualifiedNameWithWildCard';';

Entity:
	'entity' name=ValidID ('extends' superType=JvmParameterizedTypeReference)? '{'
		features+=Feature*
	'}';

Feature:
	Property | Operation;

Property:
	(modifier=Modifier) name=ValidID ':' type=JvmTypeReference ';';

Operation:
	(modifier=Modifier) 'def' name=ValidID '(' (params+=FullJvmFormalParameter (',' params+=FullJvmFormalParameter)*)? ')' ':' type=JvmTypeReference 
		body=XBlockExpression;

Modifier:
	 final?='final'? & static?='static'? & visibility=Visibility;	

enum Visibility:
	 PACKAGE='package' | PRIVATE='private' | PROTECTED='protected' |  PUBLIC='public';

QualifiedNameWithWildCard :
	QualifiedName  ('.' '*')?;

I get no jvmmodelinferrer.
When I save the file "Sample01.entity" then happens nothing.
The file is saved, thats all.

Hi please compare your projects with the one from the domain model
example. Especially the grammar and workflow

I have no solved the Problem.
But I have one more problem. The java-class is saved in the src-gen folder in the default-package.
What must I do, that it saved in the correct package in the src-gen folder

My code is
package org.lunifera.metamodel.dsl.entity.jvmmodel

import com.google.inject.Inject
import org.eclipse.xtext.common.types.JvmDeclaredType
import org.eclipse.xtext.naming.IQualifiedNameProvider
import org.eclipse.xtext.util.IAcceptor
import org.eclipse.xtext.xbase.jvmmodel.AbstractModelInferrer
import org.eclipse.xtext.xbase.jvmmodel.JvmTypesBuilder
import org.lunifera.metamodel.dsl.entity.entity.Entity
import org.lunifera.metamodel.dsl.entity.entity.Operation
import org.lunifera.metamodel.dsl.entity.entity.Property

class EntityJvmModelInferrer extends AbstractModelInferrer {
	@Inject extension JvmTypesBuilder
	@Inject extension IQualifiedNameProvider

   	def dispatch void infer(Entity e, IAcceptor<JvmDeclaredType> acceptor, boolean isPrelinkingPhase) {
		acceptor.accept(
			e.toClass( e.fullyQualifiedName ) [
				documentation = e.documentation
				if (e.superType != null)
					superTypes += e.superType.cloneWithProxies
					
				for ( f : e.features ) {
					switch f {
				
						Property : {
							members += f.toField(f.name, f.type)
							members += f.toGetter(f.name, f.type)
							members += f.toSetter(f.name, f.type)
						}
				
						Operation : {
							members += f.toMethod(f.name, f.type) [
								documentation = f.documentation
								for (p : f.params) {
									parameters += p.toParameter(p.name, p.parameterType)
								}
								body = f.body
							]
						}
					}
				}
			]
		)
   	}
}

Hans-Georg,

you should start and write unit tests and learn more about EMF, Xtext
and debugging. Your grammar clearly separates packages by semicolon thus
the defined entity is not contained in something that has the name
org.sample.

Please be aware of the fact that most people in this forum do this in
their spare time. It's not often a good idea to throw screen shots,
complete model inferers and grammars into a question and let others do
your homework.

Best regards,
Sebastian
