Exercise

Building on the previous labs, in this exercise you will implement the server code for the web service.

Prerequisites

Objectives

Discover how to implement the server code.

Setup Tasks

Open the CalculatorSoapBindingImpl.java file that you created previously. Or download the file (JAVA).

Tasks

Modify the file to resemble the following code fragment:

      public double add(double in0, double in1) throws java.rmi.RemoteException
      {
          return in0 + in1;

      public double subtract(double in0, double in1)throws java.rmi.RemoteException
      {
          return in0 – in1;
      }
  }

Save the file.
Compile the server code.
