Can someone suggest the best / correct way of configuring the handlers in the getPipeline() method. When the client sends a message to the server it consists of custom objects, which contain the data required by the server. I have configured the handlers as shown below:
public ChannelPipeline getPipeline() throws Exception {
ChannelPipeline pipeline = pipeline();
SSLEngine engine = SecureSslContextFactory.getServerContext().createSSLEngine();
engine.setUseClientMode(false);
pipeline.addLast("ssl", new SslHandler(engine));
pipeline.addLast("decoder", new ObjectDecoder());
pipeline.addLast("encoder", new ObjectEncoder());
pipeline.addLast("pipelineExecutor", new ExecutionHandler(pipelineExecutor));
// and then business logic.
pipeline.addLast("handler", new SecureServerHandler());
return pipeline;
}
When I compile using Netty 3.2.7 Final, I get the following warning:
Warning(78,33): ObjectDecoder() in org.jboss.netty.handler.codec.serialization.ObjectDecoder has been deprecated
When the client send the message I get the following runtime error:
WARNING: Unexpected exception from downstream.
