Creating the Java Interface and Classes

To integrate with the application server Spring framework, the Java service you create must provide separate interface and implementation classes.

The following example shows a basic interface class and an implementation class.

package com.vmware.myService;
 
public interface MyService {
  String echo (String message);
}
 
public class MyServiceImpl implements MyService {
  public String echo (String message) {
    return message;
  }
}
