[protege-discussion] Protege on the Amazon Cloud and webstart question

[Timothy Redmond]

I don't know how the Amazon Cloud works in detail but you may get more 
information about how things work from reading [1].  In particular it is 
quite likely that you actually need to perform "black magic trick #2" 
but I don't know how this is set up.  In any case, these pages should 
give you a picture of how RMI works and how you can use the

-Djava.rmi.server.hostname

parameter as well.

But you should be warned that several people have tried these techniques 
in the past and found them very difficult.  You have to have a detailed 
understanding of networks in specifically the network configuration of 
the amazon cloud servers to make this work.
