On some Linux OS (RHEL 5, CentOS, Fedora, Fuse,...), the default os '0.0.0.0' isn't allowed. So you've got a warning at the installation:
[Petals.Container.Components.petals-bc-soap]-WARNING 2010-09-23 18:40:22,567 /0.0.0.0 is not a valid local address, using the wildcard one
WARNING 2010-09-23 18:40:22,567 [Petals.Container.Components.petals-bc-soap]
/0.0.0.0 is not a valid local address, using the wildcard one
Further, at each connection, you will have a "Connection refused". Even you configure your network to accept a 'Broad Cast Binding', then the axis modules (rampart or wsaction for examples) chose only one IP to bind on (why?). So if you've got many IP's (like all the classic servers on production, with differents eth IP to invoke a service, to administrate or supervise), you've got some function not bind on some IP (a fun random way of life
)
Only 'localhost' is a good host, recognized by all the OS's, and with a great security approach (you work locally by default, and open only on your chosen IP on production).
