Unable to stablish a connection using JDBC Drivers and Datasources

Question

Hi all,
I am using SQL Server 2005,
I configured the driver(name:SQL2005) and added sqljdbc.jar
Also created a datasource with this information:
Application name: TEST
Name: TEST
Desc: TEST
I gave TEST as Alias.
I selected the driver I've created before(SQL2005), with JDBC Version 1.x(No AX Support)
As Driver Class I put com.microsoft.sqlserver.jdbc.SQLServerDriver
As DatabaseURL I put jdbc:sqlserver://<ServerName>:<port>;database=<dbName>
User: Admin, Password: pass
In SQL Engine I put "VENDOR SQL"
when I save it and try to Start Selected StandAlone Application I get this Error:
Error occurred while starting application 'sap.com/TEST'
these are the details:
Caused by: java.lang.ClassNotFoundException: com.microsoft.sqlserver.jdbc.SQLServerDriver
Found in negative cache
Loader Info -
ClassLoader name: [library:SQL2005]
Parent loader name: [Frame ClassLoader]
No references !
Resources:
   C:\usr\sap\J2E\JC00\j2ee\cluster\server0\bin\ext\SQL2005\sqljdbc.jar
   C:\usr\sap\J2E\JC00\j2ee\cluster\server0\bin\core_lib\opensqlport.jar
Loading model: {parent,local,references}
Can Anyone please help me?
Thanks in advance!

Thank you very much, seeing that document it was much easier to solve the problem.
Now I am facing other problem:
When I try to execute a query(for example : select * from
) I get this error:
Error occurred while executing init statements
java.rmi.RemoteException: com.sap.engine.services.dbpool.exceptions.BaseRemoteException: SQL statement(s) cannot be executed over DataSource "TEST". If you are using an Open SQL DataSource, you must register your tables using JDDI before you request them. Reason: com.sap.engine.services.dbpool.exceptions.BaseSQLException: ResourceException in method ConnectionFactoryImpl.getConnection(): com.sap.engine.services.dbpool.exceptions.BaseResourceException: SQLException thrown by the physical connection: com.microsoft.sqlserver.jdbc.SQLServerException: La conexión a la instancia con nombre  ha fallado. Error: java.net.SocketTimeoutException: Receive timed out.
Do you have any idea how to solve this?
thanks again
Bye!
