Hosting the Marvin Applet

The Marvin Sketch package can be downloaded as .zip package from http://www.chemaxon.com/download/marvin/for-web-developers/#marvinapplets and hosted on an internal server.

Please note that Internet Explorer and JRE have a small problem regarding authentication. Java Applet cannot use current Internet Explorer authentication mechanism (for NTLM and Kerberos). Because of this, if you host the applet on a server which requires windows authentication, and the client opens the applet with Internet Explorer, the applet will prompt for a username and password. To avoid such issue we strongly recommend allowing anonymous access for the location where our applet is hosted.

On Windows based Operating System the most common Web Server is IIS. In order to host our Marvin Sketch applet under IIS you will have to add the following mime types in the HTTP headers tab on the properties dialog of the web site or the server:

  • .properties = "text/plain"
  • .data = "application/octet-stream"

Optional mime types in case you will also host some molecules files which applet will download from your server:

  • .mrv = "chemical/x-chemaxon-marvinfile"
  • .mol = "chemical/x-mdl-molfile"
  • .cdx = "chemical/x-cdx"
  • .sdf = "chemical/x-mdl-sdfile"
  • .smi = "chemical/x-daylight-smiles"
  • .rxn = "chemical/x-mdl-rxnfile"
  • .rdf = "chemical/x-mdl-rdfile"
  • .pdb = "chemical/x-pdb"
