Hi I am getting same error,

But i am using Eclipse , jdk 6, Jboss 5, Sporing message listener. Weblogic 11g is using to send messages . Getting messages from WL Queue to my app thru some logic.
I am able to print xml messages in the console, but getting exception before unmarshal this,

Code :
JAXBContext jc = JAXBContext.newInstance("com.bopeep.gen");
Unmarshaller unmarshaller = jc.createUnmarshaller();
// unmarshall into Classes from a File
bilgMsg = (BILGMSG) unmarshaller.unmarshal( new StreamSource( new StringReader(stringMessage)));

Please see the below error and help to resolve this
Exception:
11:41:49,475 WARN [DefaultMessageListenerContainer] Execution of JMS message listener failed, and no ErrorHandler has been set.

Hi Chitti,

Are you attempting to use EclipseLink MOXy as your JAXB provider or the reference implementation? If you wish to use MOXy be sure to specify a file named jaxb.properties in with your domain classes with the following entry:

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory


You also appear to be hitting a ClassLoader issue. You can try using 

JAXBContext jc = JAXBContext.newInstance("com.bopeep.gen", DomainClass.class.getClassLoader());

Hi Blaise,

I am not using EclipseLink MOXy as my JAXB provider .

I am using only JBOSS eap 5 Server and jdk1.6 version.
I am not downloading any jars explicitly like using artifacts, its using JBOSS -jaxb-impl.jar and jaxb-api.jar files.

i am trying to add
JAXBContext jc = JAXBContext.newInstance("com.bopeep.gen", DomainClass.class.getClassLoader());

but how to get DomainClass?
I added this parameter, but not able to get this DomainClass.class API.

Thanks

I coudnt fine DomainClass.class.getClassLoader().

I used like below.
JAXBContext jc = JAXBContext.newInstance("com.dnb.bopeep.gen", this.getClass().getClassLoader());

but got the same exception.
