Subject Tomcat 4.1.12 taking IPs or Ports not assigned to it?
Date Fri, 25 Oct 2002 19:20:53 GMT

EXECUTIVE SUMMARY:
  - Single Windows 2000 (SP3) Server with JDK 1.4.1_01
  - Running IIS 5.0 and Tomcat 4.1.12
  - Two IP addresses assigned to a single NIC (1.2.3.4, and 1.2.3.5 for
    example)
  - IIS has one website (all other websites have been stopped) assigned to
    1.2.3.4:80 
  - Tomcat has one website assigned to 1.2.3.5:80
  - If Tomcat is started after IIS, Tomcat reports "java.net.BindException:
    Address already in use: JVM_Bind:80"
  - If Tomcat is started before IIS, IIS reports "Address already in use"
  - Tomcat server.xml file is included at bottom.

MORE DETAILS:
I have a Windows 2000 Server (SP3) with IIS 5.0 and Tomcat 4.1.12 installed
using JDK 1.4.1_01.  The machine has two static IPs assigned to it (I'll use
1.2.3.4, and 1.2.3.5 for examples) and the IIS website is configured to use
one of these address at port 80 (1.2.3.4).  The default Tomcat HTTP1.1
connector has been updated and the configuration file has been modified by
adding the "address" attribute and assigning the other IP (1.2.3.5) to it.
The "port" attribute has been modified to port 80.

When I try and start Tomcat, it reports that the address is already in use.
However, I have verified that it is indeed NOT in use.  I have verified this
assumption by creating an additional IIS website and assigning it to the IP
I had assigned to the Tomcat connector (1.2.3.5) as well as to port 80.  I
can start both IIS websites (1.2.3.4:80 and 1.2.3.5:80) and access them both
with the correct IPs.

An additional test I conducted was to stop all IIS websites, and then start
Tomcat on its previously assigned IP (1.2.3.5) on port 80.  It started
successfully and could be accessed.  Then, however, I tried to start the
original IIS website (on 1.2.3.4), and it failed to start reporting the
address was in use.  The ONLY way I could get them both running was to
assign them different port numbers (which sort of eliminates the whole
purpose of having two different IPs in the first place).  How can I fix this
issue?

TOMCAT CONFIGURATION FILE:
My configuration file (with the sample IP and comments removed) looks like
this:

<Server port="8005" shutdown="SHUTDOWN" debug="0">
  <Listener className="org.apache.catalina.mbeans.ServerLifecycleListener"
                debug="0" port="-1" login="admin" password="admin"/>

  <Service name="Tomcat-Standalone">

               acceptCount="10" debug="0" connectionTimeout="60000"
