[OFBiz] Users - remoteStoreEntitySyncDataHttp

[Si Chen]

Hi David,

I think RMI transport is the better way to go, and I was able to get it 
to work.  However, the problem that I am having is getting it to go over 
a firewall, from a remote to a local server behind the firewall.

Our network's public ip address is 68.65.195.207, and within the 
firewall, our ofbiz instance is running at 192.168.1.100.  From the 
remote server, it has to call 68.65.195.207, and the firewall router can 
route the rmi port to 192.168.1.100.  However, java requires a hostname 
parameter to tell it what the IP address of the RMI recipient is.  If I 
set it it to 192.168.1.100 which is the machine's local IP, RMI calling 
it from the server won't be able to find it.  If I set it to 
68.65.195.207, then jotm/objectweb won't be able to start--it'll say 
that it can't find the rmi server it needs.  If I set carol.properties 
to 68.65.195.207, then jotm complains that it can't rebind to a 
different address.

Ugh.

So I think maybe we'll have to resort http transport.  What do you 
think?  Is there any other way to get RMI over a firewall?

Thanks!

Si
