Connection to Oracle 11g from network machine fails via java

I have orace 11g running on 192.168.1.217 and I am trying to connect it using JDBC driver with java and it gives me following error

IO Error: The Network Adapter could not establish the connection

Library I am using is ojdbc6.jar

Here is my code

public void makeOracleConnection() {
        try {
            Class.forName("oracle.jdbc.OracleDriver");
            oraCon = DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.217:1521:orcl", "hr", "hr");
            oraStmt = oraCon.createStatement();
            oraRsStmt=oraCon.createStatement(ResultSet.CONCUR_READ_ONLY,ResultSet.TYPE_SCROLL_INSENSITIVE);
        } catch (Exception e) {
            System.out.println("Error while making connection with Database  : " + e.getMessage());
        }
    }

I have also tried to ping on 192.168.1.217 then pins is successful. Also TNSLISTENER is running on that machine. please help.
