Create jdbc with sqlserver2000 error

Hi,everyone

when i deploy the jdbc connection pool,the server occurred an error.

And that is:

Operation 'pingConnectionPool' failed in 'resources' Config Mbean. Target exception message: com.microsoft.jdbc.sqlserver.SQLServerDriver

the setting is:

Datasource classname:com.microsoft.jdbc.sqlserver.SQLServerDriver

user:sa

password:sa

databaseName:jdbc:microsoft:sqlserver://localhost:1433;databaseName=mater

And i had set the path to invoked the jdbc driver.(i am not sure it were correct)

i have tried servel times by changing all i can do,althought the error is shorter,but it was faild again and again

i hope you can help me conquer the trouble

thanks again
