Running following code on tomcat throws null pointer exception. Running same code in java main method runs fine.

        RestClient rc = new RestClient(clientID, clientSecret, serverURL);

        System.out.println("server-> " + rc.server);

        try {

            rc.authorize(username, extension, password);

            GetVersionsResponse result = rc.restapi().list();

            System.out.println("Result " + result.uri);

            rc.revoke();

        }

        catch (IOException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

        catch (RestException e) {

            // TODO Auto-generated catch block

            e.printStackTrace();

        }

HI, Ideally you should not get the null pointer. How you are loading ring central dependencies ? If you are using maven or gradle then try to use latest version jars.

It looks like something is wrong in your project settings that did not import the RingCentral SDK properly. I don't see this line printed in your post:

System.out.println("server-> " + rc.server);

Can you double check or show how you import the SDK?

Sorry thanks for your input. I figured out.
