Where to place postgres JDBC driver jar on tomcat

Hi, I have been getting an error in my java web application "No suitable driver found for jdbc:postgresql://...."

This is a maven java web application.  The jar is included as a dependency in the pom file and when the WAR is built out the jar can be found in webapps/MyApplication/WEB-INF/lib.  

I also tried placing the jar in /usr/share/tomcat/lib.  I am still recieving the same error.  I have tried this on a local DB with postgres and the driver works fine.  Can anyone help me out?

Can you post the error as it is exactly please (maybe change the odd letter, but not the form) as it could be the url rather than driver placement

The error message is "No suitable driver found for jdbc:postgresql://10.233.1.40:5432/postgres"  I am connecting to this DB via pgadmin and it seems to work just fine with this IP address.

Here is my actual code
	private String getCustomersResults() throws SQLException {
		log.info("The customer results will be printed");
		String url = "jdbc:postgresql://10.233.1.40:5432/postgres";
		Properties props = new Properties();
		props.setProperty("user", "postgres");
		props.setProperty("password", "postgres");
		Connection conn = DriverManager.getConnection(url, props);
		Statement statement = conn.createStatement();
		
		
		log.info("select price from public.customer_rating");
		
		ResultSet rs = statement.executeQuery("select price from public.customer_rating");

		String price = "";
		while (rs.next()) {
			price = rs.getString("price");
		}
		log.info("The price is " + price);
		rs.close();
		conn.close();
		return price;
	}

How would your code know which driver class to use? You didn't tell it

My understanding was that the JDBC code will look for the driver in your build path.  I have a postgres driver.... is there a way to explicitly tell it?  Is this code not correct?
