[jboss-user] [Installation, Configuration & DEPLOYMENT] - .NoClassDefFoundError: org.jboss.dom4j.DocumentFactory

Hi, I am running jboss 4.2.0 on Ubuntu and when I start the application server I get the following error Caused by: java.lang.NoClassDefFoundError: org.jboss.dom4j.DocumentFactory at java.lang.Class.initializeClass(libgcj.so.70) at org.jboss.dom4j.io.SAXReader.getDocumentFactory(SAXReader.java:645) at org.jboss.dom4j.io.SAXReader.createContentHandler(SAXReader.java:969) at org.jboss.dom4j.io.SAXReader.read(SAXReader.java:449) at org.jboss.dom4j.io.SAXReader.read(SAXReader.java:291) at org.jboss.mx.metadata.XMLMetaData.build(XMLMetaData.java:255) at org.jboss.mx.modelmbean.XMBean.(XMBean.java:253) at org.jboss.mx.modelmbean.XMBean.(XMBean.java:282) at java.lang.reflect.Constructor.newInstance(libgcj.so.70) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:1233) at org.jboss.mx.server.MBeanServerImpl.instantiate(MBeanServerImpl.java:286) at org.jboss.mx.server.MBeanServerImpl.createMBean(MBeanServerImpl.java:344) at org.jboss.system.ServiceCreator.install(ServiceCreator.java:212) I am unclear on why this error is occuring. Can someone give me some insight on how to resolve this issue? I have check the forum archive but there does not appear to be any mention of this issue. Any help would be greatly appreciated.
