Hi, I don't know if it's the right place to ask my question, but I can't find any reason, why an application.xml could not hold multiple context roots. The context-root-uniqueness prevents me from doing it. But after removing the constraint, it works like a charm with virtual hosts. Can anyone point me into the right direction, how to avoid this error, without setting my modified application_5.xsd as xsi:schemaLocation. Thanks for the help, Peter Balogh
