Re: SOAPException: Error opening socket: Connection timed out:

To go through an HTTP proxy with Apache SOAP 2.3.1, your client code must create an instance of SOAPHTTPConnection, call setProxyHost, setProxyPort and (optionally) setProxyUserName and setProxyPassword, then call call#setTransport to use this instance.

For the nightly build of Apache SOAP and, I believe, any version of Axis, one uses System properties.  For example,

    java -Dhttp.proxyHost=myproxy -Dhttp.proxyPort=myproxyport me.MyClient

The http.proxyHost, etc., system properties follow Sun's standards.
