[xwiki-users] Error at installing Xwiki with JBOSS and MySQL

Hi, I'm trying to install Xwiki on a W2003 server, using a JBOSS container (4.2.2GA), and a MySQL database (5.0.67). I followed the steps described in the Xwiki Admin Doc (without the DS reference in xwiki.xml) I'm getting an error when starting the JBOSS server. 11:21:48,406 INFO [TomcatDeployer] deploy, ctxPath=/xwiki, warUrl=.../deploy/xwiki.war/ 11:21:53,718 ERROR [[/xwiki]] Exception lors de l'envoi de l'ΘvΦnement contexte initialisΘ (context initialized) α l'instance de classe d'Θcoute (list ener) org.xwiki.container.servlet.XWikiServletContextListener java.lang.NoSuchMethodError: org.apache.commons.beanutils.ConvertUtilsBean.register(ZZI)V at org.xwiki.properties.internal.converter.ConvertUtilsConverter.initialize (ConvertUtilsConverter.java:48) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:409) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookup (EmbeddableComponentManager.java:111) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:383) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookup (EmbeddableComponentManager.java:111) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:383) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookup (EmbeddableComponentManager.java:111) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:383) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookup (EmbeddableComponentManager.java:111) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:383) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookupList (EmbeddableComponentManager.java:128) at org.xwiki.component.internal.DefaultComponentManager.lookupList (DefaultComponentManager.java:105) at org.xwiki.observation.internal.DefaultObservationManager.initialize (DefaultObservationManager.java:129) at org.xwiki.component.embed.EmbeddableComponentManager.createInstance (EmbeddableComponentManager.java:409) at org.xwiki.component.embed.EmbeddableComponentManager.initialize (EmbeddableComponentManager.java:343) at org.xwiki.component.embed.EmbeddableComponentManager.lookup (EmbeddableComponentManager.java:101) at org.xwiki.container.servlet.XWikiServletContextListener.contextInitialized (XWikiServletContextListener.java:75) at org.apache.catalina.core.StandardContext.listenerStart (StandardContext.java:3856) at org.apache.catalina.core.StandardContext.start (StandardContext.java:4361) at org.apache.catalina.core.ContainerBase.addChildInternal (ContainerBase.java:790) at org.apache.catalina.core.ContainerBase.addChild (ContainerBase.java:770) Can you help ?
