Issue

I try to implement Oauth2 into my project using this blog

I am newbie on Spring framework, so occured an exception such as ClassNotFoundException, altough all comliant classes exist under right package though. Source (maven project) can be seen on github Thank you

Error begins with:

Solution

The essential problem regarding the exception was the build path problem. When i moved security-configuration.xml file content into business-config.xml, ide warned me about build path problem. So i checked the build path of project, maven dependecies seem to be unchecked. I had changed version of JDK previously, so i think that caused unchecked situation. Unfortunatelly, noticing took for a while...
