Data Sources (Tomcat) - mysql

Question

I tried setting up a Data Source in Tomcat to use a mysql driver, but couldn't get it to work (my Servet wasn't able to find it using a context lookup). I got told by someone that Tomcat had a problem with Data Sources.
So I placed the mm.mysql.jar file into Tomcat's /common/lib/ and am now using the drivers directly like this;
ClassLoader cl = this.getClass().getClassLoader();
Class.forName("org.gjt.mm.mysql.Driver", true, cl).newInstance();
conn = DriverManager.getConnection("jdbc:mysql://xxx.xxx.no/dbname?user=xxx&password=xxxx");It works fine,
but I'm wondering if this will cause problems for me later? What about connection pooling etc. that I had to specify when setting up the data source in Tomcat.

PROGRESS !!
Initial problem
To set up a connection with DataSource by following
JWSDP-1.0 tutorial on Servlet's
I set up a connection with DriverManager by following

I set up a connection with DataSource by following
-- TOMCAT 4.1.12 > DOCUMENTATION > JNDI DataSource Howto
My guessing thought is that the root cause might be a mysql-configuration theme ..
for example, to configure
"javauser@localhost identified by 'javadude' "
actually GIVES acces,but if you try
c:>mysql -u javauser -pjavadude
I get denied acces ..!?
