You may have to write your own unmarshaller, i'm afraid (but > i'm not a specialist, so anyone with better knoweldge, please catch the ball > ;) Well the problem of getting multiple xml mesages back to back, was what I was trying to resolve. But couldn't, coz, again didn't knew how to remove the read part from IoBuffer, once the trailing message was detected and if it continued for a while my System would be out of memory, I guess. BTW, when does the IoBuffer gets free up? Using an XML parser would be like too much, coz it would parse and throw parse exception each time the xml was incomplete and if the IoBuffer had trailing xml message, it won't parse crying about invalid message :-( Again performance becomes critical. If anybody intent to use a similar implementation, VTD-XML parser (http://vtd-xml.sourceforge.net/) will be worth evaluating. I need to do some homework on IoBuffer/ByteBuffer, like how to copy chunk from middle (something like substring) and how to remove the mark once it's set. :-) Long way to go -- thanks ashish Blog: http://www.ashishpaliwal.com/blog My Photo Galleries: http://www.pbase.com/ashishpaliwal
