BindExceptionFutureExample.java

//...
final int port=8888;
ServerBootstrap b = new ServerBootstrap();
//...

b.bind(port).addListener(new ChannelFutureListener() {
  @Override
  public void operationComplete(ChannelFuture future) throws Exception {
	  if (!future.isSuccess()) {
		  if (future.cause() instanceof BindException) {
			  System.err.println("Bind Exception on port : " + port);
			}
		}
					
  }
}).sync().channel().closeFuture().sync();
