I am trying to make Axis 1.4 communicate with NTLMv2 authentication webservice,Because internal Axis implementation uses HttpClient that doesn't support NTLMv2 I amconsidering a commercial library (called Jespa) .As far as I understand I will have to replace the transport implementation in:client-config.wsddTo a custom sender class:<transport name="http" pivot="java:com.actimize.util.MyHTTPSender"/> Are there any other steps I need to consider? Thank you!
