N. Tisserand updated CXF-3171:
------------------------------
Description:
When VM args "{{-Dhttp.proxyHost=xxxxxxxx -Dhttp.proxyPort=3128}}" are set,
there is no way to connect a webservice directly without passing throuh the
proxy xxxxxxxx.
The client CXF is build as following :
{code:java|borderStyle=solid}JaxWsProxyFactoryBean factory = new
JaxWsProxyFactoryBean();
factory.setServiceClass(MyWs.class);
factory.setAddress(bundle.getProperty("url.web.service"));
MyWs instance = (MyWs) factory.create();
Client client = ClientProxy.getClient(instance);
HTTPConduit conduit = (HTTPConduit) client.getConduit();
HTTPClientPolicy httpClientPolicy = conduit.getClient();
httpClientPolicy.setAllowChunking(false);
// Force NO proxy ?
httpClientPolicy.setProxyServer(null);
httpClientPolicy.setProxyServerPort(0);
// httpClientPolicy.unsetProxyServerPort(); // tried without success
conduit.setClient(httpClientPolicy);
{code}
When creating the instance with , CXF use HttpURLConnectionFactoryImpl (or
HttpsURLConnectionFactory) to open the url :
{code:java|borderStyle=solid} if (proxy != null) {
return (HttpURLConnection) url.openConnection(proxy);
} else {
return (HttpURLConnection) url.openConnection();
}
{code}
When the variable "{{proxy}}" is null, {{url.openConnection()}} is used, and
benifits of VM args ({{http.proxyHost}} and {{http.proxyPort}}).
The only solution to bypass the proxy, while keeping existing VM args, is to
add a System property "{{http.nonProxyHosts}}" in order to exclude the host of
the proxy. This can be done with an other VM arg
"{{-Dhttp.nonProxyHosts=xxxx}}" or programmatically :
{{System.setProperty("http.nonProxyHosts", "xxxx")}}
According to
http://download.oracle.com/javase/6/docs/technotes/guides/net/proxies.html
(chapter 3 Proxy class) when no proxy is required url.openConnection() should
be used like this :
{code:java|borderStyle=solid} url.openConnection(Proxy.NO_PROXY);{code}
The technote points out : ??"Now, this guarantees you that this specific URL
will be retrieved though a direct connection bypassing any other proxy
settings, which can be convenient."??
I think that using {{url.openConnection(Proxy.NO_PROXY)}} could fix this
problem in :
*
org.apache.cxf.transport.http.HttpURLConnectionFactoryImpl.createConnection(Proxy
proxy, URL url) > line #51 (release 2.3.1)
*
org.apache.cxf.transport.https.HttpsURLConnectionFactory.createConnection(Proxy
proxy, URL url) > line #120 (release 2.3.1)
