BEA WLS 9.2 MP2 tries to create initial context on the wrong
IP

Hello,

we are facing a strange problem in a Weblogic communication between BEA WLS 8.1
SP6 (HP JDK 1.4.2.16) & BEA WLS 9.2 MP2 (HP JDK 1.5.0.10).

The situation is the following:
Both Weblogic servers are running under HP-UX PA-RISC and using in all listener
configurations the DNS name of an HP Package [DNS1]. (Attention: This Package
DNS Name [DNS1] has another IP [20.20.20.30] address than the physical server
[20.20.20.20]!).

Now the Weblogic 8.1 Server establish an connection to the Weblogic 9.2 Server
(EJB call). So far so good.
Inside this EJB another connection is been made back from the Weblogic 9.2 to
the Weblogic 8.1 server.

And now the trouble starts:
IWeblogic 9.2 now uses  the wrong IP address to access Weblogic 8.1. It tries to
use the physical server IP address instead the Package IP address. Because of
the fact that all listeners only registered to the Package IP (DNS Name) this
will fail!.

We already double checked that we using the DNS name [DNS1] when we initialize
the context:

 props.put(Context.PROVIDER_URL,"t3://DNS1:8001");

In the whole code we never using the physical server IP address [20.20.20.20]

We have no idea why Weblogic 9.2 uses the wrong IP address.

Just FYI: This is an upgrade project. The same constalation mentioned before
works fine if only two BEA Weblogic 8.1 servers involved!  

Maybe somebody can help.

Thx a million.
