Thread: Exception: java.sql.SQLException: No suitable driver

I am trying to write a jdbc application for the first time and I can't seem
to connect to the database. I think my code is write. I suspect that my
problem is in my run script. PrintJob is the name of the class I am running
which wants to access the database. Anyone have any suggestions?

I am using the jdbc6.5-1.1.jar downloaded from the postgresql jdbc web site.

here is the error I'm receiving:

Exception: java.sql.SQLException: No suitable driver
java.sql.SQLException: No suitable driver       at java.sql.DriverManager.getConnection(DriverManager.java:111)
atjava.sql.DriverManager.getConnection(DriverManager.java:134)       at PrintJob.ConnectDatabase(PrintJob.java:186)
 at PrintJob.main(PrintJob.java:496)
 


here is my run script:

#! /bin/bash

# NOTE
# The environment variable JDKTOP must be set to point
# to the top of the jdk directory before running this
# script

CLASSPATH=.:$JDKTOP/lib:../jar/jdbc6.5-1.1.jar

# the host name must be followed by a slash
DBURL=jdbc:postgresql://*.*.*.*/

DBUSER=******

# since the password is stored in this script, you want to insure
permissions
# are adequate to keep prying eyes away
DBPASSWD=*******

# set VERBOSE to blank if you want to turn the PrintJob server's verbose
mode off
VERBOSE=-verbose

cd ./class

java -Djdbc.drivers=postgresql.Driver PrintJob -dburl $DBURL -dbuser
$DBUSER -dbpasswd $DBPASSWD $VERBOSE

cd ..

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
