youre script looks good !
but the error you get is typical a problem to find no driver(wrong
classpath or misplaced driver)
call java with -verbose flag and check if anything from jdbc6.5-1.1.jar
is loading.
if not check again your classpath there must a mistake
else
look in the jdbc.jar and check if postgresql.Driver.class is in it and
you have
a path like postgresql/jdbc2 or postgresql/jdbc1 eqvivalent to your jdk
i hope to solve your problem
