I was trying out examples from keycloak 1.5.0, specifically i was trying third-party 

example. Same example worked fine while i took distribution (keycloak-appliance-dist-all-1.1.0.Final)

I did following steps. 

1. Installed keycloak 1.5.0

2. Set third-party client with valid redirect URL as /oauth-client/*

3. Keycloak Json mentioned below (towards end of that email)

4. Initially when i deployed then i got error (No class definition error :Lorg/keycloak/servlet/ServletOAuthClient)

   then added files from keycloak-wf9-adapter-dist-1.5.0.Final.zip.

5. After that application could deploy but when i type http://localhost:8080/oauth-client/ and click on "pull data"

   then getting error.  I would appreciate if you could pls let me know how this error can be fixed ?

    Any module missing ?
