### Build and run the provider
```bash
# mvn clean package
-# mvn -Djava.net.preferIPv4Stack=true
-Dexec.mainClass=org.apache.dubbo.demo.provider.Application exec:java
+# mvn -Djava.net.preferIPv4Stack=true
-Dexec.mainClass=org.apache.dubbo.samples.provider.Application exec:java
```
### Call remote service in consumer
```java
-package org.apache.dubbo.demo.consumer;
+package org.apache.dubbo.samples.client;
+
import org.apache.dubbo.config.ApplicationConfig;
import org.apache.dubbo.config.ReferenceConfig;
import org.apache.dubbo.config.RegistryConfig;
