Please respond to

I am trying to configure JNDI to access Oracle 9i R1,
according to JNDI Datasource HOW-TO,
however I am not obtaining a lot of success when I go
to establish the connection.
In the end of this e-mail I will list some fragments of the configuration
of server.xml,
web.xml and of my class java that I am using to accomplish the connection
test.
The reference $CATALINA_HOME/common/lib/*. jar is in CLASSPATH of the
system
Fragment of configuration of server.xml

Method of the class java that makes the connection test
public String obtem_dados()
{
Connection conn = null;
Statement stmt = null;
ResultSet rset = null;
resultado = new StringBuffer();
try
{
Context initContext = new InitialContext();
Context envContext = (Context)initContext.lookup
("java:/comp/env");
DataSource ds = (DataSource)envContext.lookup
("jdbc/sged");
conn = ds.getConnection();
stmt = conn.createStatement();
rset = stmt.executeQuery("SELECT COUNT(*) FROM
V$SESSION");
if (rset.next())
{
resultado.append("N�mero de Conex�es -> ");
resultado.append(rset.getString(1));
resultado.append("<br>");
}
}
catch (java.lang.Exception e)
{
resultado.append(e.getMessage());
resultado.append("<br>");
}
finally
{
if (conn != null)
{
try
{
conn.close();
}
catch (java.lang.Exception ex)
{
resultado.append(ex.getMessage());
resultado.append("<br>");
}
}
}
return ((resultado.toString()));
}
Ao executar o m�todo anterior, recebo a seguinte mensagem de erro:
Cannot create JDBC driver of class 'oracle.jdbc.driver.OracleDriver' for
connect URL jdbc:oracle:[EMAIL PROTECTED]:1521:XXX
Algu�m tem alguma id�ia do que pode estar acontecendo?
Excuse me for the gigantic message.
I thank in advance.
