Subject RE: CATALINA_BASE/lib on tomcat6 (RHEL6)
Date Thu, 16 Jul 2015 13:58:05 GMT
Chris,

Yes, I suspect this is due to RHEL's re-package.  

$CATALINA_HOME = /usr/share/tomcat6
$CATALINA_BASE = /srv/tomcat/myapp

$CATALINA_HOME/conf/catalina.properties does exist and contains the proper common.loader line.
 However, unless I manually copy $CATALINA_HOME/conf/catalina.properties into $CATALINA_BASE/conf,
classes are not being loaded from $CATALINA_BASE/lib, presumably because common.loader is
incorrect due to the lack of $CATALINA_BASE/conf/catalina.properties.

I verified this by sticking "common.loader: <%= System.getProperty("common.loader") %>"
in a test JSP page  and invoking it with and without catalina.properties in $CATALINA_BASE/conf.

I have a ticket open with RHEL and they will hopefully be able to tell me the expected behavior
here, since it obviously differs from a 'stock' Tomcat6 installation.

(apologies for top-posting)

Thanks,

Josh
