In the application server environment, you might have to do some tricks to
get the proper ClassLoader which can find your database.xml document.
ClassLoader.getSystemResourceAsStream will use the SystemClassLoader to get a
stream, which could be different from the classloader that is actually used
to load your classes.
perhaps you can use the line:
this.getClass().getClassLoader().getResourceAsStream(systemId);
from your EntityResolver implementation. That will make sure that the
classloader that loaded the EntityResolver can be used to load database.xml
instead of the System ClassLoader.
