--------------------------------------
Andres, you are right that there is an issue. However code you suggest has
another issue. Instead of buf.capacity() - you need to check buf.limit() while
comparing with 125.
{code:title=Bar.java|borderStyle=solid}
// Encode the in buffer according to the Section 5.2. RFC 6455
private static IoBuffer buildWSDataFrameBuffer(IoBuffer buf) {
IoBuffer buffer = IoBuffer.allocate(buf.limit() + 2, false);
buffer.setAutoExpand(true);
buffer.put((byte) 0x82);
if(buf.limit() <= 125){
byte capacity = (byte) (buf.limit());
buffer.put(capacity);
}
else{
buffer.put((byte)126);
buffer.putShort((short)buf.limit());
}
buffer.put(buf);
buffer.flip();
return buffer;
}
{code}
> Create a WebSocket iofilter for use in Apache Mina TCP servers

> Shephertz has created a websocket iofilter that can be added in Apache mina
> tcp server chain. The features of this codec are
> 1) Works with binary data sent/received over websocket
> 2) Abstracts the client details from the Handler code i.e. the handler need
> not be aware that the remote endpoint is a browser or native client.
> 3) Tested with binary data sent/received on latest chrome and firefox
> browsers. IE 9 doesn't support websockets and we will make changes if
> required for IE 10 when its released and if it supports websockets.
