generateToken

void generateToken(java.lang.String url)

Generate a new token.

No token received may be due to

1. a Repository failure
   can be checked with a frameSend("ping")
   => reissue a token
2. the failure of a station before

Pb: how to avoid that all stations generate a new token?

Solution: wait for a url-dependent time before generating a new token.

Parameters:

url - RL of the DeployIF web service of the subscribed PageBox

frameForward

void frameForward(java.lang.String url,
                  TokenFrame frame)

Forward the frame to the next running PageBox or to the Repository.

Parameters:

url - PageBox url

frame - frame to forward
