no, no, no. this should be handled only once during servlet init via
the overridden loadConfiguration method that Jason suggested. and
though i didn't include it in my example, the first part of his
suggestion should still be included:
//Configuration file to be read is specified as
//the init param 'org.apache.velocity.properties'
Properties p = super.loadConfiguration(config);

both VelocityServlet and VelocityViewServlet will first search the
servlet config's init-params, then search the servlet context's
init-params. so the answers to your questions are no and yes,
respectively.
