Nobody knows if it's possible to hide the basic authentication in the proxy layer using SOAPProxy? Any tips would be appreciated
The SOAPProxy is basicly a hidden HttpRouter which has the capacity to refer to a keystore. You can find some examples on how to put SSL on a HttpRouter in the JBossWiki.
The SSL/keystore part was never an issue, only the basic authentication part. Even though I had 'Client Credentials Required' set to false, the supplied credentials in the http client properties file didn't work. However, when I commented out/removed authscope-realm (not required parameter), it worked.
