Greeter Example

2 min read

Writing a client-server application with Ice does not take much code. See for yourself!

In this example, we describe how to write a simple client-server application, step by step.

This application is a typical Greeter: a server hosts a Greeter object that produces custom greetings, and the client calls the server to get these greetings. Even though it’s simple, this application demonstrates best practices and provides a good foundation for starting any Ice project.

We present this example in the following sections:

Using Slice - How to use the Slice IDL to define a contract between clients and servers.
Writing a server - How to implement Ice objects and host them in a server.
Writing a client - How to write a client that communicates with an Ice server.

We write the server first: a client has nothing to call until a server is running.

Using Slice - How to use the Slice IDL to define a contract between clients and servers.
Writing a client - How to write a client that communicates with an Ice server.

This example has no server section for this language mapping. You can run the Greeter server from C++, C#, Java, Python or Swift, and call it from the client you write here.

The complete source code for this example is on GitHub, alongside several other demo programs.
