tomcat 7: is it possible to config tomcat common classloader to
point to other location?
Hello,
I am using TC 7, and the doc says, TC common classloader load $CATALINA_HOME/lib for thosecommonly shared lib jar files. Is it possible for me to config it pointing to other location? I know ifI define $CATALINA_BASE to point to a outside location, will $CATALINA_BASE/lib be used for TCcommon classloader to pick up there? thanks

$CATALINA_OPTS gets only used at startup. If you need the variable every
time (start and stop), you should use JAVA_OPTS.

Hello, Churck,
I tried to use $CATALINA_OPTS env to set my ${oracle.common.home} variable in common.loader property,
starting TC has no problem, but when shutting down TC, it gives me error saying it could not find the jar. I
added echo to print CATALINA_OPTS in catalina.sh script.

You can see I tried to set ${oracle.common.home} pointing to a valid location, but
TC could not recognize it. Do you know what missing?

It's not a placeholder, it's a reference to a system property, evaluated when the .xml or .properties file is scanned. Read the doc:
"Apache Ant-style variable substitution is supported; a system property with the name propname may be used in a configuration file using the syntax ${propname}. All system properties are available including those set using the -D syntax, those automatically made available by the JVM and those configured in the $CATALINA_BASE/conf/catalina.properties file."

I mean, can I define my own placeholder there? like ${foo.bar}, so that I don't have to hardcode catalina.propertiesto let TC include my external jars? Is there mapping like CATALINA_BASE -> catalina.base, and CATALINA_HOME -> catalina.home,or FOO_BAR -> foo.bar?

Nothing, unless you change catalina.properties. Tomcat 5.5 and earlier used the shared loader, but it was de-configured in Tomcat 6.0 and later.

Not sure what you mean by "built-in placelholder"; they are properties that undergo variable substitution when the file is loaded and parsed. Read RUNNING.txt in Tomcat's home directory for an explanation.

Thank you, Chris, in catalina.properties file, I also saw shared.loader property, as you know, the TC7 doc says "System", "Common", and "Webapp" classloaders. If "common.loader" map to common classloader, what "shared.loader" get map to?
And are those ${catalina.base} and ${catalina.home} built-in placeholder for TC7?

Take a look at conf/catalina.properties:
common.loader=${catalina.base}/lib,${catalina.base}/lib/*.jar,${catalina.home}/lib,${catalina.home}/lib/*.jar
Looks like both are used.
You can define this property to be anything you'd like, including adding
another directory somewhere else without disturbing anything.
Note that changing catalina.properties will be surprising to anyone who
tries to debug your Tomcat installation after you move-on to another
job. So, be sure to explicitly document what you're doing.
