Time for action – exposing a method using the client interface

Carry out the following steps to expose a method using the client interface:

1. Open the EmpDirectoryModuleImpl.java file and add the following method:

   public String getHelloWorld(){
       return "Hello World";
   }

2. Go to the Java tab from the EmpDirectoryModule.xml file, and click on the pencil icon in the Client Interface section.

3. The Edit Client Interface window will open. Move the getHelloWorld() method from the Available list to the Selected list as shown in the following screenshot:

   

4. Click on the OK button to create the interface method.

What just happened?

We now have the client interface defined to expose the getHelloWorld() method from the EmpDirectoryModuleImpl class to the outside world. The EmpDirectoryModule.java interface will be created to expose the method as a service in the data control. The EmpDirectoryModuleClient class will implement the interface to invoke the getHelloWorld() method from EmpDirectoryModuleImpl.
