Hi Jesse,
You can specify namespace-to-package mappings in the castor.properties file or using the addNamespaceToPackageMapping() method.
This will map all elements from a given namespace to a specific package.
Remember that when you have <ns1:foo> that the ns1 prefix must be mapped to an actual namespace eg:
<ns1:foo xmlns:ns1="http://org.acme/foo-namespace";>
In the castor.properties file you would add the "http://org.acme/foo-namespace"; to the set of namespace to package mappings, eg:
# XML namespace mapping to Java packages # org.exolab.castor.xml.nspackages=\ http://org.acme/foo-namespace=org.acme.foo,\ http://org.acme/bar-namespace=org.acme.bar
As for the NullPointerException, those are never good. If you can open up a bug report and attach a simple test case which reproduces the problem that would be great.

Is there a way for to specify a namespace-to-package mapping for tags the same way you can use unmarshaller.addNamespaceToPackageMapping() for xsi:types?
I want to be able to specify the mapping that way when castor sees a tag with a namespace, it will know exactly what package to look for that class in. I know I can do this with a mapping file, but then I would have to have to do this for every single tag that needs the namespace resolution. The schema I am working with is extremely large, so this really isn't an option.
i.e.
<engine> <ns1:processor> <name>p1</name> </ns1:processor> <engine>
Is there a way for castor to see ns1 and map that to a package for any tag? Actually it would almost be good enough if I could tell castor to ignore the namespace. Is that possible? Currently, it sees ns1:processor and gives me a NullPointerException probably because it can't find the processor field using introspection?
