There is a requirement of single sign on application can i do this with web services??? If so how can i do ?? otherwise is there any way for doing this???
Web services generally play no role in setting up SSO. See the http://faq.javaranch.com/java/SecurityFaq for links to a couple of Java SSO implementation in the "Web applications and HTTP" section.
What kind of applications are these - Web apps? Desktop apps? Something else? [ October 22, 2008: Message edited by: Ulf Dittmer ]
