Java EE 8 Design Patterns and Best Practices

Implementing the EJB asynchronous methods

The following code shows an example of a stateless EJB asynchronous method. Suppose there is a method responsible for approving and scheduling student test reviews and we want to call this method in an asynchronous way:

@javax.ejb.Statelesspublic AcademicServiceBean { @javax.ejb.Asynchronous  public Future requestTestReview( Test test) {  // ... }  }

 We will look at a bean client that requests a test review service, as follows:

@Named @SessionScopepublic TestController {     @Inject    private AcademicServiceBean academicBean;     private Future statusTestReview;        public void requestTestReview(){ /* get Test object which has the test data, like: test date; student who made the test; discipline, etc.*/ ...
