[Building Sakai] Sakai Webservices - Axis

[Steve Swinsburg]

Hi Sandeep,

The Sakai web services all require a valid session to work. This session is checked for every web service call .Some are admin only, meaning that unless you have an admin session, you can't perform that action. If you need anonymous access to a web service, it's pretty easy to write your own, or just duplicate one and just remove the session check, but I wouldn't recommend it unless it is an action that is normally anonymous.

So, you need to first call the SakaiLogin.login method with some credentials which will give you a session string. Save that session string in your app and use it for subsequent web services calls in SakaiScript etc.

To answer your question about a link, yes, you can add the session string to the URL and construct a link like:

https://your.sakai.server/portal/?sakai.session=thesessionhere

You need to enable this behaviour in sakai.properties though:
session.parameter.allow=true 

cheers,
Steve
