The examples you've provided aren't examples of MIME type chaining by
themselves. You've sent two virtually identical servlets that don't appear to
depend on any particular MIME type.
I tested MIME type chaining today pretty extensively and it actually works fine.
MIME type chaining is when you define MIME type/servlet associations (mapping
servlets based on MIME types instead of URL prefixes or file extensions) in
JRun. You can do this by hand editing the configuration files or via the JMC.
The JMC will create entries in the webapp.properties for your web app, which
configure a built-in servlet called mime-servlet. You can get servlets to chain
based on MIME type in this way. How did you configure your MIME type chaining
with your examples? I am thinking it's more of a configuration problem than a
bug. Please provide the relevant portion(s) of your
local.properties/webapp.properties/web.xml.
