J. Nessunnome commented on XMLBEANS-346:
----------------------------------------

I believe I am encountering the same or a similar issue. 

I am using several different schemas in my project (all without namespaces, and there \
is nothing I can do about that).  They are each compiled into a separate jar, each \
using a separate package, using the xmlbeans ant task.  I can only seem to \
successfully parse xml (using the Factory.parse(String xml) method) for the schema \
jar that is first in the classpath, otherwise I get a ClassCastException as described \
in this bug.

I've done some debugging, and I'm coming to the conclusion that the structure of the \
schemaorg_apache_xmlbeans.namespace package is probably responsible.  Since my \
schemas do not have namespaces, each of jars I've built share some files that are \
identically named in identical packages.  Specifically, I've seen that each jar has a \
schemaorg_apache_xmlbeans.namespace._nons.xmlns.xsb file that seems to point to the \
actual schema for that jar.  If the factory uses this file to determine some of the \
classes it will use to parse the xml it has, this may explain the ClassCastException, \
as it's only looking at the first file on the classpath and not the correct one for \
the XML.

I think I would be beneficial to have a schema compiler feature to specify the \
location where these files are generated, like the Java package options, since \
sometimes the developer can't control if namespaces are used in his schemas or not.
