Hi Netrista.. thank you for your help.. I checked my enviroment variables and i didn't find problems. I think that was copy paste mistake. I put first the oracle driver library reference into the classpath enviroment variable

C:\>echo %classpath%
.;D:\oracle\ora92\jdbc\lib\classes12.zip;C:\Progra m Files\Altova\xmlspy\XMLSpyInterface.jar;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msbase.jar;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\msutil.jar;c:\program files\Microsoft SQL Server 2000 Driver for JDBC\lib\mssqlserver.jar

I performed your suggested command and i couldn't get the version of each class i'm trying to use

C:\>java oracle.jdbc.driver.OracleDriver
Exception in thread "main" java.lang.NoSuchMethodError: main

C:\>java com.microsoft.jdbc.sqlserver.SQLServerDriver
null

any other thing that it could be used? thanks!
