I am using Axis 1. How to I configure the server and client to force the client to authenticate with a certificate? Does Axis 1 make use of the httpd.conf file to force this authentication? Does the client code which invokes the web service only have to set properties in order for the SSL to take place? I have seen many different versions of this solution. I have searched this forum and it seems like only some properties need to be set. Please let me know.
