We're working with JBoss 4.2.3.GA and building a Seam/RichFaces app; it doesn't have any database connectivity but sends form info to email. We have the following JAR files in the /WEB-INF/lib/ folder of the app:

antlr-runtime.jar   
commons-beanutils.jar   
commons-digester.jar   
core.jar   
jboss-el.jar   
jboss-seam-debug.jar   
jboss-seam-ioc.jar   
jboss-seam-mail.jar   
jboss-seam-ui.jar   
jboss-seam.jar   
jsf-facelets.jar   
richfaces-api.jar   
richfaces-impl.jar   
richfaces-ui.jar  

What are the minimum JAR files necessary for a Seam/RichFaces app with Seam email functionality? Are there JAR files we can eliminate from the above list? Thanks.
