SQLException

When attempting to use the native iSeries JDBC driver to access the local 
iSeries DB2 db, I get the following SQLException:
 
"The Username and/or password supplied is incorrect." (SQL1403N)      
 
The JDBC Driver used is: 
 
com.ibm.db2.jdbc.app.DB2Driver
 
and the URL string is:       

jdbc:db2:MYDATABASE;errors=full;translate 
binary=true;naming=system;libraries=ICBSUATDB1 
ICBSSMS712;user=MYUSER;password=MYPASSWORD
 
The configuration is a Java application and a DB2 both on the _same_ iSeries 
(AS/400) machine.
 
I have tried different renditions of the URL string, in particular:
   1) With *LOCAL instead of MYDATABASE and
   2) Without the user and password properties
Four (4) combinations in all. In all four cases the above error ("The Username 
and/or password supplied is incorrect.") was gotten!
 
(Reminder: Both Java app and DB2 db live on the same iSeries box)
 
Any help as to (i) why this error occurs and (ii) how it can be eliminated 
would be _greatly_ appreciated!!!
