[Bamboo-Users] How to change Get timeout

[Martina.Baldanzi at isti.cnr.it]

Dear Olaf,
thanks for your reply.
The timeout, that you specify, is a generic timeout valid for all ONC/RPC
calls.
I have a question, if I change the file OncRpcClient.java, I change the
value of the Put method timeout too?

    Hi Martina,

    In the past, I had the impression that those parameters in the config
    file have no real effect. Actually, the timeout parameter is
hard-coded
    in the ONCRPC library. (http://remotetea.sourceforge.net/)

    see also:
    http://bamboo-dht.org/pipermail/bamboo-users/2006-August/000826.html

    I'm not quite sure if this solves your problem.

    Cheers,
    Olaf
