Connection to remote db2 database through JDBC fails

I am new to db2. I want to ask if it is possible to just connect to a db2 database on a remote db2 server through my java application? Merely having jdbc driver of type 4?

I am having db2jcc4 driver on build path.

When I try this simple code

 public static void main(String[] args) {
        Class.forName("com.ibm.db2.jcc.DB2Driver");
        System.out.println("Driver loaded");

        try {
            Connection dbConn =     DriverManager.getConnection("jdbc:db2://192.168.0.103:50000/ABC", "****", "*****");
        } catch (SQLException e) {
            e.printStackTrace();
        }

}

Connection fails with this exception. I am unable to trace what is exactly happening?

Also the db2diag.log after getconnection is :

Are you using AES encryption mechanism in Java 7? If so, I found this solution via Googull at IBM.com

Otherwise, try creating a DB2SimpleDataSource object directly.

private DB2SimpleDataSource db2;
private void configureDataSource() {

     db2 = new DB2SimpleDataSource();
     db2.setServerName("192.168.0.103");
     db2.setPortNumber(50000);
     db2.setDatabaseName("ABC");
     db2.setUser("****");
     db2.setPassword("*****");
     db2.setReadOnly(true);          
}

Then connect like this Connection c = db2.getConnection() or this Connection c = db2.getConnection("****", "*****")
