JDBC Adapter connection problem

Hi,

I’m installing JDBC Adapter on wM6.0 and have problem on connection creation. The parameters I gave as below:

Transaction Type :LOCAL_TRANSACTION
DataSource Class:oracle.jdbc.pool.OracleConnectionPoolDataSource
serverName:localhost
user:isv6
password:****
databaseName:localora
portNumber:1521
networkProtocal:(empty)
other Properites: driverType=thin

And I got error msg. below:

[ART.118.5011] Adapter Runtime (Connection):Unable to create new connection exercise3.adapter:jdAdapterCon.
[ADA.001.204] Cannot connect to the database with DataSource class “oracle.jdbc.pool.OracleConnectionPoolDataSource”.
[wm-cjdbc30][Oracle JDBC Driver]Unable to connect. Invalid URL.

Can anybody give some advice, please?Many thanks.
