Tomcat installation frustration!

[Simon Doran]

Hi all,

  I have never previously had a problem installing Tomcat. It should be straightforward, right?

  However ... I have a new RHEL 6 box. I am not familiar enough with this OS to know whether there are any issues I should be looking out for. Here are the setup and the symptoms:

* Latest version of Tomcat (7.0.39) installed under /srv/xnat/Tomcat

* All Tomcat directories owned by user xnat.

* catalina.sh start

* Environment variables set as follows:

export JAVA_HOME='/usr/java/latest'

export CATALINA_HOME='/srv/xnat/Tomcat/Current'

alias start_tomcat='sh /srv/xnat/Tomcat/Current/bin/startup.sh'

alias stop_tomcat='sh /srv/xnat/Tomcat/Current/bin/shutdown.sh'

where /usr/java/latest resolves to /usr/java/jdk1.7.0_17 (have also tried a 1.6.0 variant)

* Response to start_tomcat is

Using CATALINA_BASE:   /srv/xnat/Tomcat/Current

Using CATALINA_HOME:   /srv/xnat/Tomcat/Current

Using CATALINA_TMPDIR: /srv/xnat/Tomcat/Current/temp

Using JRE_HOME:        /usr/java/latest

Using CLASSPATH:       /srv/xnat/Tomcat/Current/bin/bootstrap.jar:/srv/xnat/Tomcat/Current/bin/tomcat-juli.jar

* Symptom: No webpage displayed when I try http://localhost:8080 and in catalina.out I get multiple failures as below.

Any help gratefully received!

Oh dear! Well that's all rather embarrassing ...

The errors came about because of the rather convoluted way I had to get Tomcat onto my RHEL system, which is not directly connected to the internet. I had to go via a Mac and, for various reasons, that now don't look so great, I decompressed the distribution onto the Mac and scp'd it over to the RHEL box. All the errors that stopped Tomcat working seem to have come from the ._ files that got created for the MacOSX resource forks.

Solution: remove all the ._ files from .../apache-tomcat-7.0.39/lib, the errors go away and my tomcat screen appears!

Good thing, cause I had NOTHING for you on this one J
