I have spent hours trying to get my built classes to be on the 
classpath for schemaexport and have failed until I put the class
in the ant lib directory which is not ideal. 
When running schemaexport I get:
C:\build.xml:220: Schema text failed: 
net.sf.hibernate.MappingException: persistent class 
[model.team.Person] not found
I have tried putting a classpath in the taskdef but that does not
work either.
