JDBC driver on UNIX machine is not estabilishing the connection

[Senthil]

I am trying to install the JDBC driver for SQL server 2000 on MY HPUX machine. After installing I am trying to run the test program. I found the following error message. Did any one help me how to resolve this problem?

java -classpath " :./lib/mssqlserver.jar ./lib/msbase.jar ./lib/msutil.jar" Test

Exception in thread "main" java.sql.SQLException: [Microsoft][SQLServer 2000 Driver for JDBC]Error establishing socket.
