Java SE (Java Platform, Standard Edition)

jdk1.2.2 is up and running and then I installed Tomcat on my Windows2000 PC.
Then in a DOS window I did this:
C:\Program Files\Apache Group\Tomcat 4.1\bin>startup

And this display resulted:
Using CATALINA_BASE: C:\Program Files\Apache Group\Tomcat 4.1\
Using CATALINA_HOME: C:\Program Files\Apache Group\Tomcat 4.1\
Using CATALINA_TMPDIR: C:\Program Files\Apache Group\Tomcat 4.1\\temp
Using JAVA_HOME: C:\jdk1.2.2

But I get "Cannot find server or DNS error" when I try
http://localhost:8080/ or http://127.0.0.1:8080/admin

Any suggestions would be appreciated.
Thanks!
