Hi Nabeel

I got this exception when hitting the following line in
OAuthAuthenticationExample: 
LinkedInRequestToken requestToken = oauthService.getOAuthRequestToken();

Seems like an issue with your jdk. Which version are you using?
I will need to do a bit more research on it as I have never encountered that
exception before.

Thanks for your help.

Hi Nabeel,

I found out the problem: i used jre6 and the app needs javax.crypto.sun class 
which
is not included in jre6. So i installed jdk6 and the problem solved. I can run
successfully the OAuthAuthenticationExample now.
