I am trying to run the Embeddable EJB3 with IntelliJ IDEA agaist JBoss and I get the same RuntimeException about a writeToDOM signature in xerces. I can understand why the person trying to run this agaist Weblogic would have issues with the xerces version incompatability but I don't see why I would have that issue with JBoss. Any information on why I am getting this exception would be greatly appreciated. java.lang.RuntimeException: java.lang.VerifyError: (class: org/apache/xerces/impl/xs/XSAnnotationImpl, method: writeToDOM signature: (Lorg/w3c/dom/Node;S)V) Incompatible object argument for function call at org.jboss.ejb3.embedded.EJB3StandaloneBootstrap.boot(EJB3StandaloneBootstrap.java:386) at gov.dia.gemini.core.ProducerBeanTest.startupEmbeddedJBoss(ProducerBeanTest.java:46) at gov.dia.gemini.core.ProducerBeanTest.setUp(ProducerBeanTest.java:35) at org.junit.internal.runners.OldTestClassRunner.run(OldTestClassRunner.java:35) at com.intellij.rt.junit4.Junit4ClassSuite.run(Junit4ClassSuite.java:59) at com.intellij.rt.execution.junit.JUnitStarter.main(JUnitStarter.java:40) Caused by: java.lang.VerifyError: (class: org/apache/xerces/impl/xs/XSAnnotationImpl, method: writeToDOM signature: (Lorg/w3c/dom/Node;S)V) Incompatible object argument for function call at org.apache.xerces.impl.xs.traversers.XSDAbstractTraverser.traverseAnnotationDecl(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.traverseSchemas(Unknown Source) at org.apache.xerces.impl.xs.traversers.XSDHandler.parseSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadSchema(Unknown Source) at org.apache.xerces.impl.xs.XMLSchemaLoader.loadGrammar(Unknown Source) at org.apache.xerces.impl.xs.XSLoaderImpl.load(Unknown Source) at org.jboss.xb.binding.Util.loadSchema(Util.java:395) at org.jboss.xb.binding.sunday.unmarshalling.XsdBinder.bind(XsdBinder.java:166) at org.jboss.xb.binding.sunday.unmarshalling.XsdBinder.bind(XsdBinder.java:137) at org.jboss.xb.binding.sunday.unmarshalling.DefaultSchemaResolver.resolve(DefaultSchemaResolver.java:248) at org.jboss.xb.binding.sunday.unmarshalling.SundayContentHandler.startElement(SundayContentHandler.java:162) at org.jboss.xb.binding.parser.sax.SaxJBossXBParser$DelegatingContentHandler.startElement(SaxJBossXBParser.java:301) at org.apache.xerces.parsers.SAXParser.startElement(SAXParser.java:1376) at org.apache.xerces.validators.common.XMLValidator.callStartElement(XMLValidator.java:1214) at org.apache.xerces.framework.XMLDocumentScanner.scanElement(XMLDocumentScanner.java:1806) at org.apache.xerces.framework.XMLDocumentScanner$ContentDispatcher.dispatch(XMLDocumentScanner.java:949) at org.apache.xerces.framework.XMLDocumentScanner.parseSome(XMLDocumentScanner.java:381) at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1081) at org.apache.xerces.framework.XMLParser.parse(XMLParser.java:1122) at org.jboss.xb.binding.parser.sax.SaxJBossXBParser.parse(SaxJBossXBParser.java:138) at org.jboss.xb.binding.UnmarshallerImpl.unmarshal(UnmarshallerImpl.java:133) at org.jboss.kernel.plugins.deployment.xml.BeanXMLDeployer.deploy(BeanXMLDeployer.java:85) at org.jboss.ejb3.embedded.EJB3StandaloneBootstrap.boot(EJB3StandaloneBootstrap.java:373) View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=3984313#...
