hi busybee,

i hope you are using connector-j for your mysql database. refer to the documentation at
[url=“http://www.mysql.com/documentation/connector-j/index.html”]http://www.mysql.com/documentation/connector-j/index.html[/url].

thanks, Sanjay and Gonzalo. I did follow the links that you pointed and followed the instructions. When I try to enable the connection, I get the following error :

"
Error encountered
[ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource conn:jdbcconn.
[ART.118.5036] Adapter Runtime (Connection): Unable to configure connection manager.
null
"

When I look at the error log, following is the stack trace I obtained.

com.wm.pkg.art.error.DetailedServiceException: [ART.118.5042] Adapter Runtime (Connection): Unable to enable connection resource conn:jdbcconn.
[ART.118.5036] Adapter Runtime (Connection): Unable to configure connection manager.

Hi Balasubramanya

I have successfully set up a connection pool using the similar settings to yours.

which version of the mysql j-connector are you using?

Try this as the DataSource class …

com.mysql.jdbc.jdbc2.optional.MysqlDataSource
