newbie: JDBC query exception: "SQL0204 *tablename* in *username* type FILE not found"

This error doesn't make sense to me, and makes me think that I'm doing something silly when connecting to my database.  Everything compiles just fine, and the connection seems to go fine (as far as I can tell) until my retrieveData procedure throws an exception that says "BLLOPER in MYUSERNAME type *FILE not found".  BLLOPER is the table name targeted by my SELECT query, and MYUSERNAME is the username I use in the Connection string to log in.  I wouldn't expect to find a table in a username.  I'm not sure why Java does.  Probably something to do with my Connection string, but if I really knew what I was doing, I wouldn't be begging for help here.

Code is cribbed heavily from:http://www.javacamp.org/moreclasses/jdbc/jdbc.html
Connection string partially derived from: http://publib.boulder.ibm.com/infocenter/hod9help/index.jsp?topic=/com.ibm.hod9.doc/help/db_url.html
