Thanks very much all -- Oracle driver now loading :)

What I changed:
Tomcat 5.0.19 which was installed when I installed NetBeans 3.6
To 
Tomcat 5.0.28
I am unsure if the NetBeans 3.6 caused the issue or something else was. Maybe, the install just went a bit weird on my XP box. What finally made me try a stand alone Tomcat install was the Management tool did not function correctly. The logging was not working as well. Therefore I said why not, nothing else has worked.
I did not use a default context or a context in the server.xml instead I used 
C:\Tomcat5.0.28\conf\Catalina\localhost\dbtest1.xml
Here's that file:
<?xml version="1.0" encoding="UTF-8"?>
<Context docBase="C:\Tomcat5.0.28\webapps\dbtest1" path="/dbtest1">
 <Logger className="org.apache.catalina.logger.FileLogger" prefix="DBTest" suffix=".log" timestamp="true"/>
 <Resource name="jdbc/OracleDB" auth="Container" type="javax.sql.DataSource"/> 
 <ResourceParams name="jdbc/OracleDB">
  <parameter><name>factory</name><value>org.apache.commons.dbcp.BasicDataSourceFactory</value></parameter>
      <parameter>
        <name>driverClassName</name>

      </parameter>
      <parameter>

        <value>jdbc:oracle:thin:@192.168.1.10:1521:to1</value>
  </parameter>
      <parameter>
       <name>username</name>
   <value>myuser</value>
  </parameter>
  <parameter>
   <name>password</name>
   <value>mypassword</value>
  </parameter>
  <parameter>
   <name>maxActive</name>
   <value>20</value>
  </parameter>
  <parameter>
   <name>maxIdle</name>
   <value>10</value>
  </parameter>
  <parameter>
   <name>maxWait</name>
   <value>-1</value>
  </parameter>
 </ResourceParams>
</Context>
My server.xml is still at the default. I did not change a thing. Therefore I will not include it.
web.xml:

Here is my app code:
/*
 * testDBConnBean.java
 *
 * Created on September 23, 2004, 11:14 AM
 */
package mybean;
import java.beans.*;
import java.io.Serializable;
import javax.naming.Context;
import javax.naming.InitialContext;
import javax.sql.DataSource;
import java.sql.*;
public class testDBConnBean extends Object implements Serializable {
    private String message1 = "error";
    
    public String testJDBCDBConn() throws Exception {
        Context initContext = new InitialContext();
        Context envContext  = (Context)initContext.lookup("java:/comp/env");
        DataSource ds = (DataSource)envContext.lookup("jdbc/OracleDB");
        Connection conn = ds.getConnection();
        message1="no error";
        return message1;
    }
    
    public String testODBCJDBCDBConn() throws Exception{
        Context initContext = new InitialContext();
        Context envContext  = (Context)initContext.lookup("java:/comp/env");
        DataSource ds = (DataSource)envContext.lookup("jdbcodbc/OracleDB");
        Connection conn = ds.getConnection();
        return "no error";
    }
    
    public String getMessage1(){
        return message1;
    }
       
}
I do have one question: How the the "java:/comp/env" work in the line:
Context envContext  = (Context)initContext.lookup("java:/comp/env");
do?
Thanks
Pete
