Class not found exception

May be installation instruction is missing something but I'm constantly getting this error : Extension is installed successfully. There is a jar file with this class but it desn't work.

Hello Nikita, Just in case: can you check that "socialauth-4.2.jar" is also available in the classpath? In case it is not, you can get it from there : http://code.google.com/p/socialauth/ (btw version 4.2 is needed for Twitter auth, while the default install comes with version 4.0). Did you install the plugin through the extension manager or "manually"? Regards,

[jkolobok]

Hello. Socialauth jar is there, but it's 4.0. I installed it using extension manager after installing xwiki.

Note that you can upgrade it using extension manager by using advanced search with "org.brickred:socialauth" as id and "4.2" version

Installed 4.2 using extension manager. Same problem. Also had to install javax.servlet api 3.0-something. I use osx jdk 1.7_25 and deploy it to tomcat 7.0.42. What else it could be?
