Hi, I'm a little confused about the split EIP pattern combined with aggregation strategy. In the example (see http://camel.apache.org/splitter.html - Split aggregate request/reply sample), the out exchange is used to retrieved the body content and also to set it because the pattern is of type InOut.
I have created an aggregator but in my case, I must use the content of the In to retrieve my body List requestMessages = new ArrayList(); if (oldExchange == null) { requestMessages.add(newExchange.getIn().getBody(RequestMessage.class)); newExchange.getOut().setBody(requestMessages); return newExchange; } else { // Get old messages requestMessages = oldExchange.getIn().getBody(List.class); // Get new and add it to the list requestMessages.add(newExchange.getOut().getBody(RequestMessage.class)); // Add to the exchange oldExchange.getOut().setBody(requestMessages); return oldExchange; } Questions : - Is the split EIP an InOut pattern ? - When I develop the aggregator like this, the headers of my messages have disappeared when the endpoint called after the end of the split receives the List of Objects. How can I avoid this ? Regards, Charles Moulliard Senior Enterprise Architect Apache Camel Committer ***************************** blog : http://cmoulliard.blogspot.com
