my code in bean as follows
public void onMessageExchange(MessageExchange exchange) throws
MessagingException {
if (exchange.getStatus() == ExchangeStatus.ACTIVE) {
logger.debug("## Received exchange with status
ACTIVE:ContractSchemaDataMapper " + exchange);
System.out.println("## Received exchange with status
ACTIVE:ContractSchemaDataMapper " + exchange);
InOut inOut = (InOut)exchange;
NormalizedMessage normalizedMessage = inOut.getInMessage();
String outMessage = processXml(normalizedMessage);
//String outMessage ="<sample>this is sample xml</sample>";
normalizedMessage.setContent(new StringSource(outMessage));
MessageUtil.transferInToOut(inOut, inOut);
channel.send(inOut);
} else{
logger.debug("## Received exchange but status not ACTIVE: " +
exchange);
}
}
when i am sending the channel , channel,send(inOut), I am getting null
pointer

<beans xmlns="http://www.springframework.org/schema/beans";
