The error is this

java.lang.NoSuchMethodError: org.wso2.carbon.um.ws.api.stub.RemoteUserStoreManagerServiceStub.addAnonymousOperations()V
    org.wso2.carbon.um.ws.api.stub.RemoteUserStoreManagerServiceStub.populateAxisService(RemoteUserStoreManagerServiceStub.java:42)

Here is my code

private boolean authenticate(String userName, Object credential) throws Exception {
    if (!(credential instanceof String)) {
        throw new Exception("Unsupported type of password");
    }
    try {
        if(stub == null) {
            stub = new RemoteUserStoreManagerServiceStub(null, serverUrl
                    + "RemoteUserStoreManagerService");
            HttpTransportProperties.Authenticator basicAuth = new HttpTransportProperties.Authenticator();
            basicAuth.setUsername(basicAuthUserID);
            basicAuth.setPassword(basicAuthPassword);
            basicAuth.setPreemptiveAuthentication(true);

            final Options clientOptions = stub._getServiceClient().getOptions();
            clientOptions.setProperty(HTTPConstants.AUTHENTICATE, basicAuth);
            stub._getServiceClient().setOptions(clientOptions);

        }
        return stub.authenticate(userName, (String) credential);
    } catch (Exception e) {
        handleException(e.getMessage(), e);
    }
    return false;
}
