Chapter 13: Server Side: Java

These techniques are required only for those who need or want to build their own server from the ground up.

13.1 Opening a Server Socket for Business

Problem

You need to write a socket-based server.

Solution

Create a ServerSocket for the given port number.

13.2 Finding Network Interfaces

Problem

You wish to find out about the computer’s networking arrangements.

Solution

Use the NetworkInterface class.

13.3 Returning a Response (String or Binary)

Problem

You need to write a string or binary data to the client.

Solution

Use the InputStream and OutputStream from the socket.

13.4 Returning Object Information Across a Network Connection

Problem

You need to return an object across a network connection.

Solution

Create the object you need, and write it using an ObjectOutputStream created on top of the socket’s output stream.

13.7 Securing a Web Server with SSL and JSSE

Problem

You want to protect your network traffic from malicious modification while the data is in transit.

Solution

Use the Java Secure Socket Extension, JSSE, to encrypt your traffic.

You MUST have set up a server certificate or you will get javax.net.ssl.SSLHandshakeException: no cipher suites in common

13.8 Creating a REST Service with JAX-RS

Problem

You want to implement a RESTful server by using the provided Java EE/Jakarta EE APIs.

Solution

Use JAX-RS annotations on a class that provides a service; install it in an enterprise application server.
