Managing Provider Tokens Like the provider, the consumer must be responsible for managing the OAuth tokens. The necessary interface for managing the consumer tokens is OAuthConsumerTokenServices which are only accessible via factory method. Assuming that the consumer can leverage an active HTTP session, the default HttpSessionBasedTokenServices and HttpSessionBasedTokenServicesFactory should be adequate.
so it appears that Spring is looking for an implmentor for OAuthConsumerTokenServices either HttpSessionBasedTokenServices OR HttpSessionBasedTokenServicesFactory http://spring-security-oauth.codehaus.org/oauth1.html#Managing_Provider_Tokens Martin > Date: Fri, 2 May 2014 15:22:01 -0700 > From: rallav...@gmail.com > To: users@tomcat.apache.org > Subject: BLOCKED threads > > All, > > Tomcat Version: 7.0.47 > JVM Version: 1.7.0_51-b13 > > I see many blocked threads (90) in the thread dump.
