Indeed there is a "setClassLoader(ClassLoader)" in Unmarshaller. Now i tried
using it like this:
----------------------------------------------------------------------
XMLContext xmlContextObject = new XMLContext();
xmlContextObject.addMapping(mapping);
Unmarshaller unmarshaller = xmlContextObject.createUnmarshaller();
unmarshaller.setClassLoader(classLoader);
Marshaller marshaller = xmlContextObject.createMarshaller();
----------------------------------------------------------------------
But it still throws the same error stack:
java.lang.NullPointerException
at
org.castor.core.util.Configuration.getObjectArray(Configuration.java:677)
at
org.castor.mapping.MappingLoaderRegistry.<init>(MappingLoaderRegistry.java:54)
at
org.castor.mapping.MappingUnmarshaller.<init>(MappingUnmarshaller.java:80)
at org.exolab.castor.xml.XMLContext.addMapping(XMLContext.java:79)
Am i setting the classloader correctly?

Hi Marko,
yes, you are right, both XMLContext and Marshaller do not expose such
methods (directly). In other words, thou shall not quote top of one's
head .. ;-).
But Unmarshaller exposes Unmarshaller.setClassLoader(ClassLoader) which
should enable you to get past your problems.
