Re[2]: Tomcat 4.0.3 & getResourceAsStream

[Jacob Kjome <ho...@visi.com>]

Hello Esteban,

It won't work with p.getClass... unless the resource you are trying to
load is in the classpath...meaning it must be within WEB-INF/classes
or WEB-INF/lib/somejar.jar and you wouldn't reference "WEB-INF".  The
classloader knows absolutely nothing about it.

If your resoruce was in the root of WEB-INF/classes (root of the
current classloader... also equivalent to putting the resource in a jar file, but
not inside a package in that jar file), the following will work:
p.getClass.getResourceAsStream("/myResource.properties");

This will work if your resource is located relative to the current
class "p" (same package as the class).
p.getClass.getResourceAsStream("myResource.properties");

This will work to find the resource anywhere in the current
classloader (make sure not to prefix with "/"):
p.getClass.getClassLoader.getResourceAsStream("myResource.properties");

This will work to find the resource even if it isn't in the same
classloader.  For instance, maybe it is in a parent classloader or a
child classloader relative to the current classloader (make sure not
to prefix with "/"):
Thread.currentThread().getContextClassLoader().getResourceAsStream("myResource.properties");

This will work to find the the resource using the servlet context and
fulfill your requirement to put all properties in WEB-INF/conf:
theServletConfig.getServletContext().getResourceAsStream("/WEB-INF/conf/myResource.properties");


For your purposes, you need the last one.  None of the others will
work unless your resource is in the classloader which WEB-INF/conf
isn't.
