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
