Lian,

When I pass a null value for InputStream to the ValidatorResources
constructor I can reproduce the exact same stack trace and error.
There clearly is an error in the java code you posted with you not
initializing the InputSource at all. If you're saying you fixed that
then the implication is that
getClass().getResourceAsStream(validationDefinition) is returning
null. Either way, from what I can see thats where the error lies. Try
putting a check for null before you initialize the ValidatorResources:

 if (in == null) {
      throw new IllegalArgumentException("resouces missing");
 }
 resources = new ValidatorResources(in);
