ethernet adapter binding in VMWare

I'm using VMWare workstation 5.5 on a Windows XP host with Red Hat AS 4 guest,
and ethernet is configured for bridged mode.
I've installed WebLogic 9.2 on the guest and left the host address empty - this
is equivalent to 0.0.0.0, so WebLogic server should bind to all interfaces, that
is, lo (loopback) and eth0; lo is assigned 127.0.0.1 (localhost) and eth0 is
assigned a "real" IP address. This does not work - WebLogic binds only
to lo and not to eth0.

If I explicitly assign WebLogic host address to the IP address of eth0, that
works, but then I don't get loopback binding!

Since other web servers, such as Tomcat and JBoss, do not have this problem, I
realize it's probably just a WebLogic problem. Can someone here help me?

Thank you very much
