If you do not see the line:
"Press a button to view an embly entry" below
then your web browser doesn't support java or you have java disabled.
Artemis on the web needs a web browser that supports java 1.1
Netscape Navigator version 4.06 through 4.75 does not support Java 1.1 correctly but Microsoft Internet Explorer version 4 or better does.
You might to try the standalone version of Artemis instead. Go to this page for more information.
