Seems you are working on an SMPP decoder using some 3rd party library. You don't need to copy all the bytes each time. Follow this 1. Check the length from SMPP header 2. Collect the bytes till the length from header is achieved (use CumulativeProtocolDecoder) 3. Once done, get the byte[] from ByteBuffer (seems you are using MINA 1.1.7)
Would recommend to upgrade to latest MINA version thanks ashish On Mon, May 25, 2009 at 11:35 AM, Arun Soman <[email protected]> wrote: > Hi > I am getting the following exceptions > >
