I have a similiar problem. I can call a ws via https using stand alone project just fine. Run same code in jboss container, get error Can not connect http client invoker. Invalid HTTP server response [403] - Service Error. Response: Service Error/403 Side note: to get around the multiple keystores, you can use this approach HttpsURLConnection.setDefaultSSLSocketFactory(sslSocketFactory); you'll find a bunch of posts on it. i can provide more detail if needed. if you find solution to 403 problem, please post it.
