Looks like your web-service is expecting special headers (either content
type or something alike), you can try setting the content type and also
set the request type to POST explicitly (in one of the peculiar use case
I had to use it explicitly) using following code:
.setHeader(Exchange.HTTP_METHOD, constant("POST"))
.setHeader(Exchange.CONTENT_TYPE, constant("application/json"))
I'll still recommend that you either look into your server logs to find
out exact root cause or enable the TRACE logging for apache http package
(assuming you are using http or http4 component) to see what's going on
the wire, compare it what postman is sending and adapt your route
accordingly.

Hi All,
I'm the new of camel. I now use apache camel to call several our
webservices.
Here is my code:
public void configure() throws Exception{
from("direct:start")
.marshal()
.string(UTF_8)
.to(TARGET http)
.process(new Processor() {
@Override
public void process(Exchange exchange) throws
Exception {
String message =
exchange.getIn().getBody(String.class);
System.out.println(message);
}
})
.to("stream:out");
I'm sure there is no problem about the target endpoint, for I can get
correct response using postman.
But camel give me 500 error.
