java.lang.IllegalStateException: unsupported protocol: 'https4'
Hi All,
I am using camel to call REST URLs. In doing so, I am setting the
CamelHttpUri header to override the URI. This works properly with http/https
(Http client 3.x). However, it fails for http4/https4 (Http Client 4.x).
Below is the stack trace for https4

Posted by bcwajapey <bc...@gmail.com>.
Are you suggesting to use "https" (Http Client 3.x) instead of "https4" (Http
Client 4.x)?
I have already tried it and https4 fails. Thats the error I have mentioned
in the thread.

Hi
Can you try with
<setHeader headerName="CamelHttpUri">
<simple>https://myapp.com${header.employeeName}?size=${header.size}</simple>
</setHeader>

Re: java.lang.IllegalStateException: unsupported protocol: 'https4'
Posted by bcwajapey <bc...@gmail.com>.
@arno noordover : Sorry did not get exactly what you meant. Are you
suggesting I have to give complete URL in "CamelHttpUri" header instead of
using header variables like ${header.employeeName}?

Re: java.lang.IllegalStateException: unsupported protocol: 'https4'
Posted by arno noordover <an...@gmail.com>.
You have two things:
1. the uri-attribute in the to-element;
2. the "CamelHttpUri" headers.
Both have a "protocol" prefix. The "protocol" prefix in de uri-attribute is
used to select the component you want to use.
When using the "CamelHttpUri" to override the URL that gets determined in
the component you need to provide the real URL in this header.
