Querying an existing Java RMI service

In this recipe, we will configure a Spring web application, so that it will be able to execute a method on an existing RMI service.

Getting ready

We will query the Java RMI service of the previous Creating a Java RMI service recipe.

We need the UserService interface so that our application knows the methods available on the RMI service:

public interface UserService {
  public abstract List<User> findAll();
  public abstract void addUser(User user);
}

User objects will be exchanged over the network, so we need the User class of the previous recipe as well:

public class User implements Serializable {    
  private String name;
  private int age;
  
  public User(String name, int age) {
    this.name = name;
    this.age = age;
  }

  // ... getters and setters
}

In real applications, these classes could be provided to the RMI client as a JAR file.

How to do it…

Here are the steps to query a Java RMI service:

1. In the Spring configuration, add a RmiProxyFactoryBean...
