Subject DNS error, no reply from Tomcat and no clues in the log
Date Wed, 21 Dec 2005 12:52:26 GMT
I'm trying to upgrade to Tomcat 5.5.14 on Windows2000.  The JRE is 
1.4.2_03.  I've deployed the compatability patch, and commented out 
the Apache Portable Runtime listener from the 'server.xml'.

I encountered an error when starting Tomcat for the first time after 
installation.  The service starts normally, but the browser reports a 
DNS error.  Netstat reports that Tomcat is listening on 8080 (for IP 
0.0.0.0).  But if I telnet to the machine's IP address and connect to 
port 8080 there is no reply.  Perhaps Tomcat is listening on a different IP?

Most perplexing, the Tomcat logs show nothing unusual.  Below are the 
(rather short) logs from my Tomcat startup.  What's missing 
here?  The Catalina logs stop before the expected 
'org.apache.catalina.startup.HostConfig checkResources', WAR 
deployment and context loading.

There are three areas I suspect issues to arise:

- The Java environment is a bit weird, with several versions of the 
JDK on the system.  When the Tomcat installer prompted for a JRE, the 
path suggested was invalid.  I opted to use 'D:\j2sdk1.4.2_03\jre' 
since I can see there is a JRE there, and JAVA_HOME points to 
'D:\j2sdk1.4.2_03'.  If I enter 'java -version' at the command line, I get:

java version "1.4.2_03"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.4.2_03-b02)
Java HotSpot(TM) Client VM (build 1.4.2_03-b02, mixed mode)

-  A JK2 ISAPI redirector is in place, and I'm working the 
installation around it.  This is because we can't restart the World 
Wide Web publishing service - it's a production service.

-  There's a separate instance of JRun on the machine, listening on 
port 8000 I think.  Is that the same as the MBean Server?

Any suggestions would be helpful.
