Tomcat and multiple IP addresses

[Ping Yu <ping_milsun (at) yahoo.com>]

Hi,
   
  I have a question that I would like ask help or suggestions from people in this maillist. 
   
  I would like to transfer a file from Machine A to Machine B. In Machine A, there are several IP addresses. However, the IP address launched by Tomcat might be different from the IP address I choose to transfer the file. Are there any ways that I can get to know which IP address that Tomcat starts with in a single machine? Are there any APIs or classes for this? Then I can use the IP address started by Tomcat to transfer my file.
   
  Thank you very much!
