How can you load local server urls on application start?

Question

Background:
I've been searching for close to two days for an answer to this question, it's full of gotchas and I can't quite get it figured out.
I have an application which contains several web services. These services load up listeners when the services are invoked which makes them available for input. The user has the option of disabling automatic load of these services and invoking them manually by typing in the local url and starting the app. The can allow the autoload which uses a the or allowing the auto load to start. Currently the local url is hardcoded in a property file and this is how the services knows the local endpoint to envoke when it autostarts.
<servlet id="AutoStart_01">
<servlet-name>autoStart</servlet-name>
<servlet-class>com.loadmy.StartupClass.Here</servlet-class>
<load-on-startup>1</load-on-startup>
</servlet>
This works all fine and well until it's deployed onto a machine that runs a local weblogic cluster that has more than one jvm (and multiple ports) loading the application up.
Problem
The question is, how can you get the applicaton to recoginize the local url for the jvm that is running which can be on different ports? Here's what I've tried
A - Using Inet.Address - This doesn't let you know what port your application is on
B - Using the load servlet on start up ( Only the init() function is called and the request object hasn't been created and the request object is what contains ther protocol, server and port information)
C - Loading a jsp page (READ... purposefully loading a jsp page) on application start. The thought here is that this contains a request object, but unfortunately on this doesn't work in my servlet container (currently tomcat 6 but the application is for a web logic machine)
D - I thought about possibly using System.properties() but no luck there
I'm at witts end on this one and I know there is something that can recoginze the local servlet container and extract the url and port from it.
Any suggestions would be great.

Hi,
I had a simmilar requirement once, i also had to display some meaningful message with the busy mode icon, but i guess that comes directly from the WD Framework and is not possible to be changed. Refer the following thread, i raised that time.
