Regarding the Oracle error:
Open a sqlplus window and log in to oracle with the same userid and password you have configured in the JDBC pool screen.
Type: select count(*) from BizDoc;
If you don’t get a count back, then you have not created the tables in the default schema for the userid and password you are providing. As soon as select count(*) form BizDoc works in sqlplus without any schema qualification for the table name, the same user id and password should also work for the JDBC connection.
If you are still getting this error after you have verified the tables have been created in the default schema for the userid, then I would run the drop scripts, and re-create, this time carefully checking for errors (like out of tablespace, etc.) when creating the tables.
I would not start working on the second error until you have the database connection issue resolved.
