Something like:
localhost/MyWebApp/jsp_or_servlet
or:
127.0.0.1/MyWebApp/jsp_or_servlet
or:
128.43.10.19/MyWebApp/jsp_or_servlet
Inconsistencies like these, can bring you headaches.
since the default session management specs bind sessions
to the url. If you change the url then you loose the session and
hence you get errors like the ones you listed below.

Hi all,
I am hoping someone can tell me why this happens! When I installed
Tomcat, my mail example did not work. I got the following error:
java.lang.NullPointerException
at java.net.InetAddress.cacheAddress(InetAddress.java:648)
at java.net.InetAddress.cacheAddress(InetAddress.java:633)
at
java.net.InetAddress.getAddressFromNameService(InetAddress.java:1016)
at java.net.InetAddress.getLocalHost(InetAddress.java:1125)
at
javax.mail.internet.InternetAddress.getLocalAddress(InternetAddress.jav a:474)
When I run the EXACT same code from my client IDE as a test it works fine!
To make it work from the web though, I had to add 127.0.0.1 <machineName>
to my hosts file. My question is, WHY? Why does it work different from
within Tomcat than straight from my test app? IS it looking up via
machine name instead of localhost? What exactly is happening here? I am
running on Redhat 8.0 and using JSDK 1.4.1.
Thanks for any help on this strange phenomenon!
Kevin
