    You need to include the postgres JDBC driver in the classpath. Commented Oct 4, 2013 at 11:08

    perhaps because there is no postgreasql driver? Commented Oct 4, 2013 at 11:11
  • I believe its not a compile time error, but it occurs at runtime! Commented Oct 4, 2013 at 11:13

  2. click buildpath->configure Build Path
  3. click libraries tab

This:

org.postgreasql.Driver

should likely be

org.postgresql.Driver

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()

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.

The path is the location of your jar file. If you download it usually goes to Downloads folder or the file you chose to download files with browser.

Please check your connection String url or connection driver and run code.
