Connection with JDBC and OS/390- DB2

Hai Travis Gibson !
Thanks for yr instant reply.
One more thing I wanted to clear.
1 Where do I get "COM.ibm.db2.jdbc.app.DB2Driver" this
driver ? and Weather it has to be downlaoded or we have to set calsspath. I searched thru IBM Site, but I could not get either downloads or any JAR files.
Please Let me Know .
I am total zero in DB2 Mainframe side.
My Mainframe Pc Host is in Denmark. I am in India. I wanted to connect the DB2, and generate some reports,is it possible.
2. I wanted to connect remote DB2. In that case How do I know the Machine name, Port Number, database Name in the Mainframe Pc.
3.I wanted to put my application into the Webserver, Servlet.So that n number of clients can view the report.
Is it Possible ? yes or No ?
If yes Do I need any Middlewares, if so Let me know ?
I hope that I have explained my requirements Clearly !
Thanks in Advance !
