HELP PLEASE: Tomcat 3 - Sun ONE Migration Problems

Question

Hi everybody. We are new Sun One users. We are trying unsuccessfully to migrate our tomcat application to this environment. in order to deploy it we have created a WAR file from the Netbeans Ide and we are trying to load it into Sun One AS... but it seems there is something wrong with the process becouse we don't have access to the defined jdbc resources. Any help would be very apreciated... and please, excuse my English.

Thanks a lot of for your fast answer, but we haven't don't too much progress...
dbping shows a message about "java.lang.NoSuchMethodException: setdataSourceName"
wich probably means mysql driver isn't fully implemented. anyway i will try
to describe the steps we make to create de pool hoping you will be able to
help us...
That's what we do:
     - first, we create a Connection pool:
          name -> MySQLPool
          database vendor -> Other
          datasource class -> com.mysql.jdbc.jdbc2.optional.MysqlDataSource
serverName -> localhost
portNumber -> 3306
user -> test
password -> test
databasename -> jdbc:mysql://localhost/pol
datasourcename -> pol
     - then, we define the resource:
          jndi name -> jdbc/jdbc-pol01
          pool name -> MySQLPool
          data source enabled -> true
     - in the web.xml of the application we got (just before /webapp):
          <resource-ref>
          <description>DB Connection</description>
          <res-ref-name>jdbc/jdbc-pol01</res-ref-name>
          <res-type>javax.sql.DataSource</res-type>
          <res-auth>Container</res-auth>
</resource-ref>
     - and we obtain the connection with a chunk of code like this:
ctx = new InitialContext();
dsName = "java:comp/env/jdbc/jdbc-pol01";
ds = (javax.sql.DataSource) ctx.lookup(dsName);
con = ds.getConnection();
If we don't write the resource-ref element at web.xml it fails at the lookup
step (not finding the resource). but when we add the element the appserver
claims "Error loading new module in virtual server: javax.naming.InvalidNameException: Real jndi name cannot beempty for jdbc/jdbc-polds.
We don't know what to do and the death line is comming here fast... any help
would be very much apreciated.          
Thanks in advance, good karma.
