Re: JNDI Tomcat and PostgreSQL Error

Hi,

I am getting the following error: java.lang.RuntimeException: Cannot load
JDBC driver class 'org.postgresql.Driver'

when trying to connect to a postgreSQL database using JNDI with Tomcat. My
configuration file and code is below.

try {

InitialContext context = new InitialContext();
Context envContext = (Context)context.lookup("java:/comp/env");
DataSource dataSource = (DataSource)envContext.lookup("jdbc/eb");
thisConnection = dataSource.getConnection();

//Register it, as we now have a connection
request.setAttribute(ServletUtils.STATEMENT_ATTRIBUTE_NAME, this);
statement = thisConnection.createStatement();
} catch (Exception e)

XML:

<Context path="/eBench8" docBase="C:\Documents and
Settings\johara.ETS.000\workspace\eB\eB" debug="1" reloadable="true">
<Resource name="jdbc/eb" auth="Container" type="javax.sql.DataSource"
driverClassName="org.postgresql.Driver" url="jdbc:postgresql://localhost/eb"
username="user" password="pass" maxActive="40" maxIdle="10" maxWait="1000"
accessToUnderlyingConnectionAllowed="true" />
</Context>

Does anyone know why I could be getting this error. As far as I know
everything is in its right place. ANy help would be appreciated.

Thanks,
James

Sent from the PostgreSQL - jdbc mailing list archive at Nabble.com.

Basically

The .jar from postgresql is not loaded.
Put it inside the tomcat lib dir (not the WEB-INF/lib).
