oracle8 jdbc begginer's question

I've posted this question some days ago, but the answers I got couldn't help.

I try to run the sample thin jdbc applet of Oracle8(jdbcapplet.htm) and I
get this message:

Loading JDBC driver oracle.jdbc.driver.OracleDriver Connecting to jdbc:oracle:thin:scott/tiger_at_COLLOSUS:1521:ORCL No more data to read from socket

Do you have any idea what this is?
TNSListener is running on port 1521,I use frontpage personal web server and
database ORCL(comes with oracle8) is running. Thanks in advance.
Please mail to me.
