Solution

  • The com.sun.facelets.* package identifies Facelets 1.x, which is a legacy standalone library intented to replace JSP in legacy JSF 1.x. Since JSF 2.x, Facelets was repackaged as part of JSF implementation in com.sun.faces.facelets.* package in jsf-impl.jar (and since Mojarra 2.1.6 javax.faces.jar).

    Unfortunately you left out the stack trace entirely which usually contains a lot more clues, but provided that you're indeed actually using JSF 2.x, as indicated by your faces-config.xml root declaration, then that can only mean that your runtime classpath is polluted with a Facelets 1.x library, usually named facelets.jar.

    If you remove it, this problem should disappear. It's not listed in your JAR list, but the exception tells otherwise.
