Hy everyone!

 

We are trying to secure an embedded restfull Jetty-Application with Keycloak. We have 

managed to redirect to the Keycloak server when a secured area on our webservice is called as also our service is called/redirected to, after login. 

However after successfull login, we get an NullPointerException (below). 

What we have debugged so far: Stateless is required, therefore we are using cookie-tokenstore. The informations are set correctly to the cookie. However it seams this informations are not assigned to/by the adapter during the redirect request.

 

Did anyone run into the same error? Any help/hint would be appreciated! Thanks

Our adapterconfiguration looks like this:

 

    KeycloakJettyAuthenticator keycloakAuthenticator = new KeycloakJettyAuthenticator();

    AdapterConfig keycloakAdapterConfig = new AdapterConfig();

    keycloakAdapterConfig.setRealm("myRealm");

    keycloakAdapterConfig.setRealmKey("MIIBIjANB ... RsvQIDAQAB");

    keycloakAdapterConfig.setAuthServerUrl("http://localhost:8080/auth");

    keycloakAdapterConfig.setSslRequired("external");

    keycloakAdapterConfig.setResource("myRealmClient");

    keycloakAdapterConfig.setPublicClient(true);

    keycloakAdapterConfig.setUseResourceRoleMappings(true);

    keycloakAdapterConfig.setTokenStore("cookie");
