Hi all,
I am using Camel 2.10.0 deployed on Tomcat 7 and I try to test following
scenario:
1. Have a CXF rest service deployed
2. Have a proxy CXF rest service over the service above, deployed under the
same Camel instance
It works fine, until I perform requests in parallel. Exception stacktrace is
attached. http://camel.465427.n5.nabble.com/file/n5716351/stacktrace.txt
stacktrace.txt
I tried following things in class
org.apache.camel.component.cxf.jaxrs.CxfRsProducer order to fix it:
1. Invoked JAXRSClientFactoryBean.setThreadSafe(true), with no success
2. Added synchronization point over line WebClient client =
cfb.createWebClient(), from invokeHttpClient method. It works, but
performance dropped on my localhost from 150 requests per second to 10
requests per second, so the fix is not acceptable.
I attach my camel-config.xml - please let me know if additional info is
needed. http://camel.465427.n5.nabble.com/file/n5716351/camel-config.xml
camel-config.xml
I am not sure if the problem lies in the configuration I performed or in the
cxf-rs component or in cxf itself.
Any idea is appreciated.
Well,I look at the code and see some JAXRSClientFactoryBean cache -
Willem can you comment on this please ? This looks suspicious.
The trace shows that the thread safety is compromised at the point of
creating web clients. I can work on a patch - though will take me a bit
of time to get to it
Dumitru - any chance you can declare jaxrs:client or WebClient [1,2]
explicitly, with a thread safe flag set and reuse it in the routes
directly ? That should do it.
Thanks
Sergey
