The exception below is thrown when a mapping file contains a reference to a filter which is not in that or another mapping file. The call to addFilterDefinition must be done first.

<code>
public class HbmBinderTest extends TestCase
{

// This throws a NPE unless the filter definition is included.
protected void addMappings(String[] files, Configuration cfg) {
// cfg.addFilterDefinition( new FilterDefinition(
// "securityFilter","true",new HashMap()) );
super.addMappings(files, cfg);
}
</code>
