Tomcat configuration question

[Neil B. Cohen-3]

Hi,

I am running a commercial program which has a (n older) version of
tomcat embedded in it. The target machines are running AIX or Linux
(RHEL4, usually).

I have written a web app that I want to install on the same machine, but
for various reasons (commercial, political, version-related) I need to
run it on a new (and different) instance of Tomcat.
I can install the latest Tomcat in a directory where it does not
conflict with the existing s/w. I know I have to edit the server.xml
file and change the shutdown port (8005) and the default connection port
(8080). I will probably change the secure connection port (8443) as
well, although I won't be using that one at the moment.

My question is - is that sufficient to allow me to run both instances of
Tomcat on the same machine without conflict? Are there other lines in
the server.xml file that need to be changed? Are there other config
files I need to look at?

My application is quite simple and my testing has been done on a machine
where I simply installed the latest Tomcat tar file (6.0.16) and started
it running, so I don't need any fancy configuration for my application.

Thanks very much,

nbc

Yes, that should be sufficient, as long as the other directories of
interest (logs, work, temp, <Host> appBase, etc.) do not overlap with
the prior Tomcat instance.  As long as you leave them at the defaults,
they go under the Tomcat installation directory, so they shouldn't need
attention.

That is correct - there is no overlap on any of the other files. Thanks
for the confirmation...

That should be sufficient. The only other thing to be aware of is if any
relevant environment variables are set for the old install that may impact
the new one.

No overlapping env variables either - the two instances will be run by
different users in completely separate filesystems...

thanks!

Hi,

I changed the server.xml file and changed the various ports from 8005 ->
9005, 8080->9090 etc.
When I start Tomcat (using startup.sh) I get the following in the
catalina.out file:

========
May 13, 2008 7:36:59 AM org.apache.catalina.core.AprLifecycleListener init
INFO: The APR based Apache Tomcat Native library which allows optimal
performanc

         at java.io.FileInputStream.open(Native Method)
         at java.io.FileInputStream.<init>(FileInputStream.java:106)
etc. etc. etc.
===========

It looks like it is looking for a security certificate - but this
doesn't happen when I start the same Tomcat software on my desktop
(testing) machine. Can someone give me a hint as to what it is looking
for, why it is looking for it, and what I need to do to get the system
running? Later in the log file, it seems that my .war file gets unpacked
and started correctly, but I can't connect to it at port 9090 - it just
hangs there forever....

Thanks,

nbc

Looks like you have configured one of your connectors to be secure. If you
post the connector elements from your server.xml, someone should be able to
help.
