# Create Logic # Create Logic
1. Create class `MyGenerator` in `org.xtext.example.mydsl.cli`
```Java
package org.xtext.example.mydsl.cli;
import com.google.inject.Inject;
import com.google.inject.Injector;
import com.google.inject.Provider;
import java.util.Map;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.equinox.app.IApplication;
import org.eclipse.equinox.app.IApplicationContext;
import org.eclipse.xtext.generator.GeneratorDelegate;
import org.eclipse.xtext.generator.JavaIoFileSystemAccess;
import org.eclipse.xtext.validation.IResourceValidator;
import org.xtext.example.mydsl.MyDslStandaloneSetup;
/**
* This class controls all aspects of the application's execution
*/
public class Application implements IApplication {
@Inject
private Provider<ResourceSet> resourceSetProvider;
@Inject
private IResourceValidator validator;
@Inject
private GeneratorDelegate generator;
@Inject
private JavaIoFileSystemAccess fileAccess;
@Override
public Object start(IApplicationContext context) throws Exception {
final Map<?, ?> args = context.getArguments();
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;
}
@Override
public void stop() {
// nothing to do
}
}
```
```Java ```Java
mport java.io.File; import java.io.File;
import java.util.List; import java.util.List;
...@@ -122,3 +69,58 @@ public class MyGenerator { ...@@ -122,3 +69,58 @@ public class MyGenerator {

``` ```
2. Change the implementaiton of the Application class like shown below.
```Java
package org.xtext.example.mydsl.cli;
import com.google.inject.Inject;
import com.google.inject.Injector;
import com.google.inject.Provider;
import java.util.Map;
import org.eclipse.emf.ecore.resource.ResourceSet;
import org.eclipse.equinox.app.IApplication;
import org.eclipse.equinox.app.IApplicationContext;
import org.eclipse.xtext.generator.GeneratorDelegate;
import org.eclipse.xtext.generator.JavaIoFileSystemAccess;
import org.eclipse.xtext.validation.IResourceValidator;
import org.xtext.example.mydsl.MyDslStandaloneSetup;
/**
* This class controls all aspects of the application's execution
*/
public class Application implements IApplication {
@Inject
private Provider<ResourceSet> resourceSetProvider;
@Inject
private IResourceValidator validator;
@Inject
private GeneratorDelegate generator;
@Inject
private JavaIoFileSystemAccess fileAccess;
@Override
public Object start(IApplicationContext context) throws Exception {
final Map<?, ?> args = context.getArguments();
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;
}
@Override
public void stop() {
// nothing to do
}
}
```
