Hello All,
We are currently using Sakai 2.8.x_all and integrated with google in
resource via rsmart instruction (
https://source.sakaiproject.org/contrib/rsmart/google-content/trunk/GoogleDocsIntegrationConfiguration.pdf
)
Everything looks great: creating comsumer key and secret and adding this
info into OAuth Providers tool in Admin Workspace,,,,,but when we type
https://mydomain.edu/google-content-tool/oauth<https://sakaidev.pomona.edu/google-content-tool/oauth>,
we have the following errors:
java.lang.NullPointerException
com.rsmart.content.google.oauth.OAuthCallbackServlet.doGet(OAuthCallbackServlet.java:139)
javax.servlet.http.HttpServlet.service(HttpServlet.java:627)
javax.servlet.http.HttpServlet.service(HttpServlet.java:729)
org.sakaiproject.util.RequestFilter.doFilter(RequestFilter.java:659)
Tomcat error looks the same:
2013-07-29 16:17:24.698 [ERROR]
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/google-content-tool].[oauth.callback]:260

resolve this problem.....
