I've dug around on the web and haven't found an explanation of this precise
scenario.
We have created a web service client using CXF. We are using wsdl2java to
generate our domain classes and Spring to define our web service client. We
have configured our certificates in the JVM and are connecting successfully
over https to our target web service.
Now we are trying to introduce a proxy server between the client application
and the remote web service. If we connect locally using http to port 8080
the request is correctly passed through the proxy server and we get our
result just as when we connect directly.
However, when we connect to our proxy server over https via port 9443, CXF
waits until its default timeout has elapsed, then reports that there is an
empty response from the proxy server, and then retries the direct
connection, successfully completing the call.
Here is the error we are getting:

Here is the configuration for the proxy server. I've disabled chunking
because this was one
suggestion of how to resolve proxy connection issues, but it doesn't seem to
make any difference:
....
HTTPConduit conduit = (HTTPConduit)cxfClient.getConduit();
HTTPClientPolicy policy = conduit.getClient();
// Set the proxy server ...
policy.setProxyServer("ip addresss for proxy server");
// ... and the proxy server port
policy.setProxyServerPort(9443);
policy.setProxyServerType(ProxyServerType.HTTP);
// Disable chunking.
policy.setAllowChunking(false);
......
Does this mean there is something wrong with our infrastructure or is it
possible that there is more configuration that we have to do
programmatically?
We're stuck. So any suggestions will be gratefully received.
