I got the required client certificate and tested it in IE and Firefox. In both IE and Firefox, it works fine. Then I tried to use it in my Jruby program by using net::https library. Below is my code: uri = URI.parse( "https://test.com/test2/request" ) ds_http = Net::HTTP.new uri.host, uri.port ds_http.use_ssl = true File.open( "client_cer.pem", 'rb' ) do |f| keydata = f.read ds_http.cert = OpenSSL::X509::Certificate.new(keydata) ds_http.key = OpenSSL::PKey::RSA.new(keydata, nil) ds_http.ca_file = CA_PATH end res = ds_http.start {|http| http.request(req, rqt) } When I run it by using Jruby, I got below exception: C:/atb/jruby-1.3.1/bin/../lib/ruby/1.8/net/protocol.rb:135:in `rbuf_fill': Recei ved fatal alert: unknown_ca (IOError) from C:/atb/jruby-1.3.1/bin/../lib/ruby/1.8/net/protocol.rb: 134:in `rbuf _fill' If anybody have any idea would be great appreciated. Thanks in advance, Jim
