Hi All, I'm trying to send a UDP broadcast packet using Netty Camel component.
I'm sending the UDP packet to producer endpoint "netty:udp:// 192.168.3.255:7777?broadcast=true&sync=false" (my network has mask 255.255.255.0) but I get the following exception: java.io.IOException: Permission denied at sun.nio.ch.DatagramDispatcher.write0(Native Method) at sun.nio.ch.DatagramDispatcher.write(DatagramDispatcher.java:51) at sun.nio.ch.IOUtil.writeFromNativeBuffer(IOUtil.java:93) at sun.nio.ch.IOUtil.write(IOUtil.java:51) at sun.nio.ch.DatagramChannelImpl.write(DatagramChannelImpl.java:616) at sun.nio.ch.DatagramChannelImpl.send(DatagramChannelImpl.java:462) at org.jboss.netty.channel.socket.nio.SocketSendBufferPool$UnpooledSendBuffer.transferTo(SocketSendBufferPool.java:207) at org.jboss.netty.channel.socket.nio.NioDatagramWorker.write0(NioDatagramWorker.java:298) ... The exception is the same addressed in this stackoverflow question: http://stackoverflow.com/questions/5134288/securityexception-sending-broadcast-from-java-on-os-x, I have tested it on my computer and it solve the problem, as you can see I'm using the "broadcast=true" option on the URI, I was expecting it to make the Camel URI work, but it doesn't. I've tried to debug the NettyEndpoint to check if channel.socket().setBroadcast(true); was called somewhere, but it is not easy as source code of sun.nio.ch.DatagramChannelImpl is not available... So, is it a bad usage from myself (am I missing to use some URI option?) or is it a bug from the camel endpoint? Thank you ! Cristiano
