Hi Emiliano, I guess the error messages could be a little better :-) The problem is that when you have a file with imports, the import in the .xsd file typically includes a relative file name for where to find the .xsd file with the imported types in it. To make that work, the loader needs the file location (schemaLocation) for the referencing (main) file. That's why you can't pass null for the second argument of XSDHelper.define() when you are loading a .xsd file with imports.
The other way you tried to do it: XSDHelper.INSTANCE.define(baseXsd, "http://www.example.org/BaseSchema";); didn't work either because you were passing a "schema namespace URI", not the "schema location". If you look at some of the JUnit tests in the sdo impl project you'll see the recommended pattern for calling define. For example, SimpleDynamicTestCase does this: URL url = getClass().getResource(TEST_MODEL); InputStream inputStream = url.openStream(); XSDHelper.INSTANCE.define(inputStream, url.toString()); It passes in the file location that corresponds to the InputStream being loaded.
