[jboss-user] [JBoss Tools (users)] - Cant instantiate class: org.jboss.seam.el.SeamELResolver

Hi, I'm facing a really strange problem when deploying a clean new project created with "File -> New -> Seam Web Project" in JBoss 4.2.3 GA with Eclipse Ganymede, jdk 1.5.0_16, jboss-seam-2.0.2.SP1, and the latest nightly build of JBoss Tools on Linux (JBossTools-200809130224-nightly-ALL-linux-gtk). To begin with, when I select "Add and Remove projects" on the JBoss Server View and I add the PruebaSeam-ds.xml and the PruebaSeam, only the last one is published in the "deploy" folder of the JBoss server. So I add PruebaSeam-ds.xml manually to the folder and run JBoss, but it throws a strange exception: 09:19:25,532 ERROR [jsf] Cant instantiate class: org.jboss.seam.el.SeamELResolver. java.lang.NullPointerException at com.sun.faces.util.Util.createInstance(Util.java:571) at com.sun.faces.util.Util.createInstance(Util.java:543) ... 09:19:27,080 ERROR [Digester] End event threw exception java.lang.IllegalArgumentException: argument type mismatch at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:39) ... 09:19:27,313 ERROR [[/PruebaSeam]] Excepción enviando evento inicializado de contexto a instancia de escuchador de clase org.jboss.web.jsf.integration.config.JBossJSFConfigureListener javax.faces.FacesException: org.ajax4jsf.renderkit.ChameleonRenderKitFactory at javax.faces.FactoryFinder.getImplGivenPreviousImpl(FactoryFinder.java:574) ... Caused by: java.lang.IllegalArgumentException: argument type mismatch at org.apache.commons.digester.Digester.createSAXException(Digester.java:3181) Could it be some missing Jar?, some bad combination of versions of Jboss, seam and eclipse?
