Hi,
I tested the servicemix-eip, and its content-enricher part appears rather
confusing.
The following is my xbean.xml using content-enricher:
<eip:content-enricher service="test:contentEnricher" endpoint="endpoint">
<eip:enricherTarget>
<eip:exchange-target service="test:additionalInformationExtracter"/>
</eip:enricherTarget>
<eip:target>
<eip:exchange-target service="test:trace3" />
</eip:target>
</eip:content-enricher>
the exchange-target of enricherTarget is simply a servicemix-bea, the
onMessageExchange method of which is as follows:
public void onMessageExchange(MessageExchange exchange) throws
MessagingException {
if (exchange.getStatus() == ExchangeStatus.ACTIVE) {
NormalizedMessage message = exchange.getMessage("in");
Source content = message.getContent();
//process content according to your logic
//e.g. to access the message body as a String use
try{
String body = (new
SourceTransformer()).toString(content);
message.setContent(content);
System.out.println("Routed to Enricher!");
System.out.println("received: " + body);
exchange.setMessage(message, "out");
channel.send(exchange);
}catch(Exception e) {
e.printStackTrace();
}
}
}
As you see, it can not be simpler which just echo the message.
The target part is similar and equally simple. I used a http bc to post a
soap message to the content-enricher like this:
<?xml version="1.0" encoding="UTF-8"?>
<e:Envelope xmlns:e="http://schemas.xmlsoap.org/soap/envelope/";>
<e:Body>
<test id="1">ok
</test>
</e:Body>
</e:Envelope>
But it gave me the following error:
Routed to Enricher!
received: <?xml version="1.0" encoding="UTF-8"?><test
xmlns:e="http://schemas.xm
lsoap.org/soap/envelope/" id="1">ok
</test>

Obviously the enricher-target had recieved the message but when routed to
the target, the "in" part of the message had mysteriously gone(that's why a
NullpointerException was invited).
Any suggestion would be greatly appreciated.
Thanks in advance!
