java integration-testing netty resteasy
I’m trying to test a resource with Resteasy using an embedded Netty instance as described in the Resteasy Docs. Injecting path parameters and query parameters works like a charm but then I tried to test a resource that injects HttpServletRequest and HttpServletResponse from the context like this:@GET @Path(“/”) public void example(@Context HttpServletResponse response, @Context HttpServletRequest request) { … }Resteasy cannot find HttpServletRequestin the context and throws the following excep

java exception-handling netty
I’ve searching around for an exception handling pattern for Netty but I’m not able to find much. Some sort of exception handling guide would be great. I have exceptions thrown that are sent to exceptionCaught but I don’t know what to do next. Can someone provide a general purpose explanation of how to handle exceptions in Netty. What is the expected pattern for handling an exception thrown from a ChannelHandler?Thanks, Matt

java netty
I am trying to implement websockets using Netty. I tried DiscardServer example and it works fine if I just run it using Telnet likeTelnet localhost 8090.So whatever the message I put in terminal window it returns me back. But now I want to implement same in browser like if I put some text message in a text area then it should display that text message on browser.I can start the websocket server using the following code ChannelFactory factory = new NioServerSocketChannelFactory(Executors.newCach

netty
Since any exception thrown in netty handler stack will generate an upstream event and eventually invoke exceptionCaught in handler the exceptions will not reach the uncaught-exception-handler. Even rethrowing that exception in exceptionCaught method doesn’t help (because netty handles it again). I would like to throw (some or all) unchecked exceptions from exceptionCaught method. Is there any way to do this?

I am trying to make tic tac toe using websockets running on glassfish. I’ve download this example form git. Firstly, I want to test it, so I run it as a normal java process on my machine.

java osgi netty
Is it possible to “undefine” a Netty AttributeKey or UniqueName instance?I have Netty 4.0.8 deployed in an OSGi container, and I have a class in separate bundle which defines a static final AttributeKey.The problem is that reloading or redeploying that bundle causes that class to be loaded again (and static initialization to happen again), so the AttributeKey constructor call blows up since the string used to identify it is already present in the map of in-use names from the last time the bundle

java scala playframework netty
Due to backward compatibilities, all HTTP requests not having defined charset are converted to ISO-8859-1 by default. Our netty served Play! application correctly receives PUT requests with JSON body, if those requests have defined charset. In case it does not, those requests should be converted to UTF-8 somehow, preferably on global application level. So I have created a Global.scala class which will be in charge of receiving of all inbound requests and converting those ‘undefined’ to UTF-8, w

I’m trying to use Netty 4 with RXTX (it’s not officially in Netty 3.x if I got this right).I think I have set up the pipeline factory correctly, but I don’t get any event generated when some data is sent to the serial port (I have confirmed with CoolTerm that there is some data coming in regularly from my device).Here is below the code I use for testing (where serialPort is something like /dev/tty.usbserial-A100MZ0L (this is a FTDI device):// Configure the client. final ExecutorService executorS

sockets netty indexoutofboundsexception decoder socketchannel
My server provides socket service for the client. My server’s DecoderHandler extends from FrameDecoder. When my client sends small data (bytes less than about 1024) to the server, the server decodes it successfully, but when my client try to write the content of an image to the server, there comes up the index-out-bound-exception.I guess the buffer chosen by decoder must have a limitation of size. So I printed out the parameter–buffer’s class. @Override protected Object decode(ChannelHandlerCon

java netty zlib
Is it necessary to use a delimiter such as LengthFieldBasedFrameDecoder with Netty’s ZlibDecoders? I had an issue where the decoder would sometimes error with “unknown compression method”, this went away when I modified the pipeline to delimit the data. The javadocs for the Zlib encoder/decoder don’t mention this as required, though their super classes do.
