Can not use JAXB into a groovy script

[obesga <ob...@tirant.com>]

Hi, fellow groovylanders


I have  a problem with groovy scripts, JAXB marshaller and I think it is the classloader of groovy scripts
But no problem executing this code into a groovy class (with a main launcher)  

The code is here
try {

    StringReader stringReader = new StringReader(dataa);
    JAXBContext jaxbContextRespuesta = JAXBContext.newInstance(MensajeWS.class)
    Unmarshaller unmarshallerRespuesta = jaxbContextRespuesta.createUnmarshaller();
    MensajeWS mensajeWSRespuesta = (MensajeWS) unmarshallerRespuesta.unmarshal(stringReader)


    println mensajeWSRespuesta;
} catch(Exception e) {
    println e
    e.printStackTrace()
}

The exception is this
java.lang.NullPointerException

I’m using IntelliJIdea to launch it
- when launched as groovy mean class - java standard it goes ok
- when launched as groovy script, error is thrown

I think it’s a class loader problem, but after searching on the web (like stack overflow) I’m out of ideas

Anyone has a similar problem ?

Thanks
