Cool! So our tests initResolver() should like this: ? public static SchemaBindingResolver initResolver() { MultiClassSchemaResolver resolver = new MultiClassSchemaResolver(); resolver.addClassBindingForLocation("jboss-ds_5_0.xsd", ManagedConnectionFactoryDeploymentGroup.class, ConnectionFactoryDeploymentGroup.class); return resolver; } I will go those testcases done after JBXB 2.0.1 Beta 2 release.
