Servlet Hibernate - java.sql.SQLException: No suitable driver found for org.postgresql.Driver

Hi,

I new at Hibernate and I wrote a littel test application in Ecplipse to test and learn how Hibernate works. This small program works well and Hibernate could find org.postgres.Driver and is reading and writing to the database correct.

Then when I try to test my code in a servlet it can't find the Postgres driver.

I get the following error:

The driver i using for Postgres i postgresql-8.4-701.jdbc4.jar.

How do I solve this issue?
