Hi Onder,
I found the explanation for this behavior. It's caused by
"constant(500)" in the expression:
exchange.getIn().setHeader(Exchange.HTTP_RESPONSE_CODE, constant(500));
The constant expression isn't evaluted to an integer when it is set;
instead it is stored as a ValueBuilder object in the exchange header.
The DefaultHttpBinding class tries to convert the ValueBuilder to an
integer and it doesn't find an appropriate TypeConverter to do this so
it doesn't set a response code.
If you do: exchange.getIn().setHeader(Exchange.HTTP_RESPONSE_CODE, 500);
it works as you expect.
In the working version, the constant expression is evaluated by the
setHeader() operation and it stores an integer in the exchange header.
This is indeed quite confusing!
Regards,
Karen

Even more strange,
i can see 500 in the logs however, response in postman is 404 in this
example.
from("direct:uploadFiles")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setHeader(Exchange.HTTP_RESPONSE_CODE,
constant(500));
}
})
.log("Response code header: ${in.header.CamelHttpResponseCode}")
.choice().when(simple("${in.header.CamelHttpResponseCode} == 500"))
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(500))
.otherwise().setHeader(Exchange.HTTP_RESPONSE_CODE, constant(404))
.end();

Hi,
i have a confusing issue while camel 3.7.5.
when i have below. i can get 500.(Working fine titled example)
However, if i have, HTTP response is not getting set to 500.
Can anyone provide any light on this?
Thanks.
from("direct:uploadFiles")
.process(new Processor() {
@Override
public void process(Exchange exchange) throws Exception {
exchange.getIn().setHeader(Exchange.HTTP_RESPONSE_CODE,
constant(500));
}
});
Working fine:
------
rest("/endpoint")
.consumes("application/json")
.produces("application/text")
.post("/upload")
.type(Void.class)
.to("direct:uploadFiles");
from("direct:uploadFiles")
.setHeader(Exchange.HTTP_RESPONSE_CODE, constant(500))
