JSF with facelets in Tomcat7

Question

I am trying to deploy a JSF 2.0 application with Facelets 1.1.14 to Tomcat7. I am getting the following exceptions:

SEVERE: The web application [/AdminUI] appears to have started a thread named [Mojarra-ResourceCache-1-thread-1] but has failed to stop it. This is very likely to create a memory leak.

Iam having the following jars under/WEB-INF/lib/

activation-1.1.jar
antlr-2.7.6.jar
asm-3.1.jar
cglib-2.2.jar
commons-collections-3.1.jar
dom4j-1.6.1.jar
hibernate-commons-annotations-3.2.0.final.jar
hibernate-core-3.6.5.final.jar
hibernate-entitymanager-3.6.5.final.jar
hibernate-jpa-2.0-api-1.0.0.final.jar
hibernate-validator-4.0.2.GA.jar
javassist-3.12.0.jar
jaxb-api-2.1.jar
jaxb-impl-2.1.3.jar
jsf-api-2.0.jar
jsf-impl-2.0.0.jar
jta-1.1.jar
slf4j-api-1.6.1.jar
stax-api-1.0-2.jar

How to resolve this?

Solution

JSF 2.0 ships with Facelets 2.0 bundled. The Facelets 1.x JAR file would only collide with this. You should remove the Facelets 1.x JAR file.

All JAR files you need for developing JSF 2.0 with Facelets on Tomcat are jsf-api.jar and jsf-impl.jar.
