With a little more playing around, I did get it to work. Your webapps
will need a <Context> similar to the following:
<Context>
<Loader className="org.apache.catalina.loader.VirtualWebappLoader"
virtualClasspath="C:/dir/classes"/>
</Context>
I assume if you put this in conf/context.xml, it will apply to all
webapps. Multiple locations can be given in the virtualClasspath
attribute by separating them with semicolons; each jar must be specified
separately.
Using the MBeans tab of JConsole, you can see the paths used by each
individual classloader; look in the Catalina -> Loader -> <appname> ->
<hostname> -> Attributes for classpath.
