Hello,

is it possible not to set the classLoader for rife? or it is mandatory
for rife in order to work properly ?
in a more general sense: is there a way to make rife work on java
google app engine? or , fundamentaly, it is not possible due to the
way rife is done.

Well, you can set the Filter init-param 'engineclassloader.enabled' to
false in web.xml, but since Google App Engine doesn't support threads,
you will get an exception on creating a new BlockingRepository which
extends ThreadGroup.
