    Hi Fernando,

    Haven't tried Jetty launcher yet (should try it someday, manual
    deployment of web apps seriously slows me down). I am pretty sure it
    introduces lots of uncertainty from the nested ClassLoaders (especially
    when mixed with Eclipse environment), so some of normal Cayenne web
    application configuration solutions
    (http://objectstyle.org/cayenne/userguide/deploy/web-application.html)
    may break.

    I am guessing that putting all cayenne XML files in CLASSPATH instead
    of WEb-INF, and using standalone app configuration
    (http://objectstyle.org/cayenne/userguide/deploy/standalone-
    application.html) will probably work.

    Thanks
    Andrus
