HELLO ALL,

I HAVE EXECUTED THIS IN COMMAND PROMPT: I'M GETTING THIS ERROR NOW:

Could not find the main class: mfirst.  Program will exit.

Harry is right. The driver can't load the authentication DLL. Go to your environment variables and add to your PATH the value C:\JavaLib\Microsoft SQL Server JDBC Driver 3.0\sqljdbc_3.0\enu\auth\x64 (choose the correct auth subfolder for your machine - i.e. x86 etc) restart your IDE and it should work as advertised

Please copy sqljdbc_auth.dll file in to jdk bin folder. i.e.C:\Program Files\Java\jdk1.6_32\bin paste file in your server side where JVM is running if consuming web services please apply same in client side as well.

Your program output doesn't look like the problem is anything to do with JDBC. You're invoking Java, passing it some environment arguments, but fundamentally telling it to start execution with the class mfirst.

And accordingly, the program output states:

Could not find the main class: mfirst. Program will exit.

This doesn't look like a proper name for the main class (no package, no uppercase characters). Are you sure you're invoking the program correctly?
