Problems loading the marvin sketch

I'm trying to use the following configuration:

  <script type="text/javascript" SRC="marvin.js"> </ script>
  <script type="text/javascript" SRC="js2java.js"> </ script>
  <script type="text/javascript">

I have already put marvin.js files in the root folder and js2java.js more exeção appears below:

ClassNotFoundException -> chemaxon.marvin.JMSketchLauch.

So I can not open Marvi Sketch

Would you like help from you.

Can you send us the part of the code where you embed Marvin?

Best Regards,

Efi
