Can't connect to MSSQL using jdbc type 4

Question

My settings in the server are the followings:
Data source class name : com.microsoft.jdbc.sqlserver.SQLServerDriver
Resource Type: javax.sql.DataSource
And in the properties, i have added
DatabaseName: jdbc:microsoft:sqlserver://SQL_SERVER:1433;DatabaseName=Borrar
Because i have downloaded the jdbc driver type 4 sp3 from microsoft site, in the AppSrv-->JVM Settings --> Path Settings -->Classpath Suffix I have the following:
C:/Sun/AppServer/pointbase/lib/pbclient.jar
C:/Sun/AppServer/pointbase/lib/pbembedded.jar
C:/Sun/AppServer/domains/domain1/lib/classes/msbase.jar
C:/Sun/AppServer/domains/domain1/lib/classes/msutil.jar
C:/Sun/AppServer/domains/domain1/lib/classes/mssqlserver.jar
Using this configuration, when i press the button "Ping" when i'm configurating the connection pool, i have this message:
" An error has occurred.
Operation 'pingConnectionPool' failed in 'resources' Config Mbean. "
Anyone can help me ??

Since nobody posted the solution and I happened to found one, I want to contribute with the following information. Hope this helps:
In order to create a connection pool for MSSQLServer
you have to:
1. Copy these files to the lib carpet inside domains/domain/DOMAIN_NAME/:
mssqlserver.jar,
msutil.jar,
msbase.jar.
You can find them in www.microsoft as a single package. Just look for JDBC Driver.
2. In the administrator console of the AppServer, go to:
Application Server -> JVM Settings -> Path Settings -> Classpath Suffix -> , and right there add the path for the previous files.
Press 'Save' and restart the server.
3. Go to JDBC -> Connection Pools -> New...
Resource Type: javax.sql.DataSource'
Database vendor: (none) (Dont select anything here).
Press Next.
4. In the field for Datasource ClassName, add
com.microsoft.jdbcx.sqlserver.SQLServerDataSource
(Here is where I`ve been having problems. I used to put com.microsoft.sqlserver.SQLServerDriver).
5. The way to find out that the server found de library is through the attributes. You have to see exactly, among others:
DatabaseName, SelectMethod, Password, User, PortNumber,ServerName.
If you see: Port. It means the path to the library is wrong.
6. Inform exactly the previous fields:
DatabaseName= yourDBName
SelectMethod=cursor
Password=yourDBPassword
User=yourDBUser
PortNumber=1433
ServerName=yourServerName
7. That�s it. Press finish. and then select the connection you just created and hit ping. You shouldnt see the annoying message about some "MBEAN bla bla bla".
Good luck. Greetings from Costa Rica.
