I'm finally making enough progress with my JDBCR4 project to where I need to concern myself with users entering a wrong user-ID and/or password: when this happens,
conn = JDBC_ConnProp(%trim(driver)
: %trim(url_db)
: prop );
throws a Java exception. (There are almost certainly other ways to make it throw an exception; bad values for driver or url_db spring immediately to mind.)

With some futzing around, I was able to redirect stdout and stderr to source PFs in QTEMP, and I got this in STDERR:
Exception in thread "main" java.sql.SQLException: The application server rejecte
d the connection. (User ID is not known.)

Now, obviously, if I were doing this in Java, I'd put it in a try/catch block. But what about calling from RPG?
