How to close ServerSocket connection when catching IOException?

Question

Sorry for question, but I'm totally noob in Java. What is the best practice to execute ServerSocket.close() when caught IOException from ServerSocket? According to docs, ServerSocket.close() throws IOException and compiler asks us to catch it. What is the proper way to close connection on IOException?

try {
    server = new ServerSocket(this.getServerPort());
    while(true) {
        socket = server.accept();
        new Handler( socket );
    }
} catch (IOException e) {
    if (server != null && !server.isClosed()) {
        server.close(); //compiler do not allow me to do because I should catch IOExceoption from this method also...
    }
}

Thank you!

That's ugly in Java. I hate it, but this is the way you should do it: Wrapping it into another try-catch:

try {
    server = new ServerSocket(this.getServerPort());
    while(true) {
        socket = server.accept();
        new Handler( socket );
    }
} catch (IOException e) {
    if (server != null && !server.isClosed()) {
        try {
            server.close();
        } catch (IOException e)
        {
            e.printStackTrace(System.err);
        }
    }
}
