JDBC Connection problem

[Ishpal]

hello,

I'm new here and trying to setup orion server.
The problem is with the data-souce.xml

My environment is as ...

O.S.-- Linux RedHat-6.2,
JDK-- jdk1.2.2 from Sun 
DataBase-- MySQL.
JDBC driver-- mm.mysql.jdbc-1.2c

In the config/data-sources.xml file My configurations are...

        <data-source
                name="Profile"
                class="org.gjt.mm.mysql.Driver"
                connection-driver="org.gjt.mm.mysql.Driver"
                location="../lib"
                url="jdbc:mysql://localhost/test"
                username="testusr"
                password="testpwd"
        />                          

I have kept the JDBC-driver's jar file in ../lib directory.

Whenever I try to start the server with

java -jar orion.jar    

I get an error as 
Error initializing server: Unknown DataSource type:
org.gjt.mm.mysql.Driver

What is it that I'm doing wrong...??
I dont want to use any other database right now.

Any help would be highly appreciated.

Thanks,
Ishpal.
