Good morning. We are currently running Jboss 4.0.4 GA on JDK 1.5. Our application was deploying and running without issue while using jbossws 1.0.3 GA. This morning I upgraded to 1.2.0.GA following the install notes included in the jbossws-1.2.0.GA.zip. Upon starting my server our application fails to deploy. I have included a section from the server.log below. Anyone encounter this issue? Any incite? Thanks! 2007-02-28 10:57:26,753 ERROR [org.jboss.deployment.MainDeployer] Could not start deployment: file:/C:/jboss-4.0.4/server/xxx/deploy/xxx.war java.lang.NoSuchMethodError: com.sun.xml.bind.api.JAXBRIContext.newInstance([Ljava/lang/Class;)Ljavax/xml/bind/JAXBContext; at org.jboss.ws.metadata.acessor.JAXBAccessor$1.create(JAXBAccessor.java:67) at org.jboss.ws.metadata.acessor.JAXBAccessor$1.create(JAXBAccessor.java:54) --- Incompletely deployed packages --- org.jboss.deployment.DeploymentInfo@e1f306a0 { url=file:/C:/jboss-4.0.4/server/xxx/deploy/xxx.war } deployer: MBeanProxyExt[jboss.web:service=WebServer] status: Deployment FAILED reason: com.sun.xml.bind.api.JAXBRIContext.newInstance([Ljava/lang/Class;)Ljavax/xml/bind/JAXBContext; state: FAILED View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4023795#...
