THe name of the driver is wrong also. Should be org.postgresql.Driver iso org.postgreasql.Driver. So maybe a typo in your java code where you do Class.forname()

This:

org.postgreasql.Driver

should likely be

org.postgresql.Driver

You would have to add the JAR file to your classpath for org.postgresql.Driver, You can download it from HERE .

You have to add the jdbc jar file on your build path. Firstly you have to download the jar from the link you provided. Then add it to build path. If you use eclipse: Right click on your project at the package explorer->Configure Build Path->Libraries->Add external jar->select your jar.
