 # Create Logic
+1. Create class `MyGenerator` in `org.xtext.example.mydsl.cli`
 
 ```Java

-import com.google.inject.Inject;
-import com.google.inject.Injector;
-import com.google.inject.Provider;
-import java.util.Map;

-import org.eclipse.xtext.generator.JavaIoFileSystemAccess;
-import org.eclipse.xtext.validation.IResourceValidator;
-import org.xtext.example.mydsl.MyDslStandaloneSetup;

+2. Change the implementaiton of the Application class like shown below.

+	@Inject

+
+    @Inject
+    private IResourceValidator validator;
+
+    @Inject
+    private GeneratorDelegate generator;
+

+

+        final String[] appArgs = (String[]) args.get("application.args");
+        
+        final Injector injector = new MyDslStandaloneSetup().createInjectorAndDoEMFRegistration();
+        System.out.println("Hello");
+        MyGenerator.execute(appArgs[1]);
+        
+        return IApplication.EXIT_OK;
