Java Database Connectivity (JDBC)

Hello everybody,
I am trying to connect to a SQLBase 7.5.1 which is the backend database to one of our legacy applications.
When i try to connect to it..using this code..

String strDbURL = "jdbc:sqlbase://192.168.xxx.xxx:2155/TEST";
		Class.forName("jdbc.gupta.sqlbase.SqlbaseDriver");
		Connection connection = DriverManager.getConnection(strDbURL,"SYSADM","SYSADM");
		System.out.println("Connected to the database");
		connection.close();

I get the following error:
java.sql.SQLException: SqlbaseSession(): failure in connection of host!

Can anyone tell me why am i getting this error message.
Thanks in advance.
Firasath.
