Invoking webservies

Is there a sample code and tutorial as how I can invoke an external webservice from visualforce page or apex code.

I also want to know how I can expose web services within force.com platform so that my external application can invoke that.

 

so basically I need web services inbound and outbound from sfdc. Any tutorials or documentation for that?

 

Thanks,

Kalpana
