Hi Malta,

One general issue: I see that you are trying to use BUILTIN 
authentication. Note that BUILTIN authentication is not 
production-quality. It is appropriate only for testing/development 
purposes. In 10.9.1 we introduced NATIVE authentication, a 
production-quality replacement for BUILTIN. You are encouraged to 
upgrade to 10.9.1 and to use NATIVE authentication instead. Hopefully, 
you will find that NATIVE authentication is easier to administer than 

Some more comments inline...

Yes, the first command creates a schema called USER_STUFF owned by the 
APP user. However, that command does not change your session to use the 
new USER_STUFF schema. To change your default schema, you need to use 
this command:

set schema USER_STUFF;

I'm afraid I don't have any theories here. Maybe someone who uses Tomcat 
on Windows can give some advice.

Hope this helps,
