using jax-rs WebClient through proxy server
Hi
I am using org.apache.cxf.jaxrs.client.WebClient to access a REST
service that sits behind a squid proxy server. The rest client WebClient
is running on Tomcat.
I have set JAVA_OPTS in the catalina startup script with my proxy server
settings:
-Dhttp.proxyHost=my.proxy.domain
-Dhttp.proxyPort=80
-Dhttp.nonProxyHosts=localhost,127.0.0.1
But the requests do not make it past the proxy server, and I just get
socket connection timeouts
Just to clarify,
My WebClient works fine when not behind a proxy server, and I can also
access the restful service using curl -x on the command line giving the
same proxy details.
My questions:
Does WebClient handle proxy servers ok ?
Is passing the proxy details to the JVM using java opts a valid
technique with WebClient ?
Is there some specific way of configuring WebClient to use proxy servers
?
Thanks for any help
Paul

The location of the configuration files has changed (as a result of the
Benson's effort), here're the updated links :

Hi Paul
After talking to Dan I've realized that you can already limit an
http-conduit configuration to individual URIs.
For example, if the endpoint address starts with
"http://books:9095/bookstore" then one can do :
<http:conduit name="http://books:9095/bookstore.*"/>
This way you can have conduits for production and test URIs (as proposed by
Dan).
Additionally, one can also have http conduits identified similarly to the
way they're identified for SOAP-based clients.
For WebClients you can do :
<http:conduit name="{http://books:9095/bookstore}WebClient.http-conduit"/>
(in 2.2.3 the local name is 'WebResource', I updated it to 'WebClient' )
For proxies you can do :
<http:conduit
name="{http://jaxrs.systest.cxf.apache.org/}BookStore.http-conduit"/>
(in 2.2.3 additional 'jaxrs' suffix is added tp the namespace, I remoced it
on the trunk )
where 'jaxrs.systest.cxf.apache.org' is a reverse package name
I'm also thinking of letting users to directly inject an HTTPConfigPolicy
instances during the creation time for simple cases. Also, I added
ClientConfiguration.getHttpConduit() to avoid casts - for JAXRS it will be
HTTP in most cases..
Please see updated
http://svn.apache.org/repos/asf/cxf/trunk/systests/src/test/java/org/apache/cxf/systest/jaxrs/security/jaxrs-https.xml
and

thanks, Sergey

RE: using jax-rs WebClient through proxy server
Posted by Paul Wilton <Pa...@bbc.com>.
Hi Sergey
Yes, that works okay, setting a proxy server on *.http-conduit
It would be really nice to be able to set this up on a per WebClient
endpoint/conduit basis though
Thanks :)

Subject: Re: using jax-rs WebClient through proxy server
Hi Paul
Sorry for a delay, I was actually about to advise you to use the in-code
configuration :-).
Will it work if you do the (proxy-related) conduit configuration similar
to the way it's done here :
http://svn.apache.org/repos/asf/cxf/trunk/systests/src/test/java/org/apa
che/cxf/systest/jaxrs/security/jaxrs-https.xml
?
I've found the similar question here :
http://www.nabble.com/Configuring-http-proxy-port-for-http-conduit-in-Sp
ring-application-context-td20399620.html
So you can probably do
<http:conduit name="*.http-conduit">
<http:client ProxyServer="my.proxy.domain" ProxyServerPort="80"/>
</http:conduit>
This will apply to all the clients though - so I'm not sure yet how to
identify an http:conduit instance with a single client only -
I may need to fix something there. I'll look into it, hopefully you can
make it workingby using the above configuration as well...-
let me know please if it will work
cheers, Sergey

Subject: RE: using jax-rs WebClient through proxy server
Hi Sergey
Regading my original question below, I have now successfully set proxy
server details programmatically by getting hold of the HTTPConduit of
the WebClient at runtime as follows:
HTTPConduit conduit =
(HTTPConduit)WebClient.getConfig(webClient).getConduit();
HTTPClientPolicy policy = conduit.getClient();
policy.setProxyServer("my.proxy.domain");
policy.setProxyServerPort(80);
However, this is not ideal - I really want to set conduit in my Spring
config
I can see in the docs how to associate a spring configured HTTPSConduit
with a JAX-WS client,
But how do I associate a HTTPConduit with a JAX-RS client in spring?
Where my WebClient is configured as a bean in spring as follows:
<bean id="myWebClient" class="org.apache.cxf.jaxrs.client.WebClient"
factory-method="create">
<constructor-arg type="java.lang.String"
value="${my.restful.service.url}" />
<constructor-arg ref="myWebClientProviders" />
</bean>
I don't see any obvious way of associating a HTTPConduit with the
endpoint
Thanks
Paul
