Rép. : Rest Service / redirect with camel-http / No serializer found for class org.apache.camel.converter.stream.CachedOutputStream$WrappedInputStream

[Daniel Langevin]

HI,  i found my problem.

sorry for the disturb.


The answer is in:
the servername.org already format the response in JSON format, so don't
have to transform the BODY receive.

it's Wrong, rest servlet try to generat automatically Json, thats the
probleme.

i only add 

after http://dummyhost>

and now it Works.


Thank's 



Daniel

Hi,

i try to implement a Rest service In OSGI Karaf 4.0.9  with Camel
2.17.7
this service redirect with camel‑http to another URL.

like 
http://serverA.org:8181/rest/XXX/geocode/30%20rue%20larue,%20quebec/adress/geom

redirect to
http://www.servername.org/search/geocode?q=300%20rue%20larue,%20quebec=adress=geom


the servername.org already format the response in JSON format, so don't
have to transform the BODY receive.

When i try with a standard Browser like, Firefox, Safari, Google
Chrome, etc. it works very well .

When i try with application Browser like utl_http from Oracle or wget
or Curl i receive and HTTP error 500 from Jetty 
Nothing in the karaf LOG

The request send to my remote server, it respond 200 OK and return de
DATA as well 
but after all data was receive 
jetty return an error to my application 

witch TCPDUMP i saw:

HTTP/1.1 500 Server Error
