Tomcat 6/Java/mySql: Data source name not found

Question

I installed the following on my laptop which has a Windows 2000 operating system:
- ODBC Connector for mySql
- the MySql Connector/J for Java
ODBC
In the Data Source ODBC Administrator of the Control panel I added a Data Source name for the mySql Database:
Data Source Name: mysql
Server: localhost
Database: mysql
When I click the Test button I get the message: Success; Connection was made!
TOMCAT
C:\apache-tomcat-6.0.18
I copied mysql-connector-java-5.0.8-bin.jar into:
- the lib folder
- the lib folder under webapps>WEB-INF\testapp
I added the above paths to CLASSPATH
TOMCAT SERVER.XML
In the server.xml file under the CONF folder I entered
<Context path="/testapp" docBase="testapp" debug="0"
reloadable="true" crossContext="true">
<Resource name="jdbc/mysql"
auth="Container"
type="javax.sql.DataSource"
description="The connection pool will be bound into JNDI with the name
java:/comp/env/jdbc/MySQLDB">
</Resource>
<ResourceParams name="jdbc/mysql">
<parameter>
<name>factory</name>
<value>org.apache.commons.dbcp.BasicDataSourceFactory</value>
</parameter>
<parameter>
<name>maxActive</name>
<value>10</value>
</parameter>
<parameter>
<name>maxIdle</name>
<value>5</value>
</parameter>
<parameter>
<name>driverClassName</name>
<value>com.mysql.jdbc.Driver</value>
</parameter>
<parameter>
<name>username</name>
<value>root</value>
</parameter>
<parameter>
<name>password</name>
<value>test</value>
</parameter>
<parameter>
<name>url</name>
<value>jdbc:mysql://localhost/mysql</value>
</parameter>
</ResourceParams>
</Context>
However, when I try to run a java servlet, I am getting the following error:
SqlException: Could not connect to database
[ODBC Driver Manager] Data source name not found and no default driver specified
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(“jdbc:mysql://localhost/mysql”, strUserId, strPassword);
MySql is actually installed on c:\Program Files\MySql\Mysql 5.0
What am I missing? How can I get the mySql connection to work?
Thanks,
Robin

Answer 1

You seem to be specifying JDBC driver while you are trying to connect to your database using ODBC,
RobinHR wrote:
     <parameter>
<name>driverClassName</name>
<value>com.mysql.jdbc.Driver</value>
</parameter>
                    and ,
RobinHR wrote:
Class.forName("com.mysql.jdbc.Driver").newInstance();
conn = DriverManager.getConnection(“jdbc:mysql://localhost/mysql”, strUserId, strPassword);
*********************You would be using "sun.jdbc.jdbcodbc.Driver" rather!
Refer MySQL sample examples/documentation on how to connect to your database using ODBC
And this on how to create a DSN
