Loading the postgreSQL JDBC driver

Question

I am trying to load a JDBC postgreSQL driver for a Java program. I know this is all over the Internet. I have tried many solutions, but none of them have worked for me.

Answer 1

Firstly you need to mention the package names using . instead of / while running the java program:

Go to your classes directory and run JDBCExample as :

java com.freire.test.JDBCExample

But it will now cry for the postgres driver class not found because postgres jar is missing in the classpath.So you need to use the classpath option while running the program and add your postgres jar to the classpath:

for windows:

java -cp .;../lib/postgresql-9.2-1003.jdbc3.jar com.freire.test.JDBCExample

for linux:

java -cp .:../lib/postgresql-9.2-1003.jdbc3.jar com.freire.test.JDBCExample
