Initializing sketch applet with MRV?

Is there a way to start the skech applet loaded with a mrv sketch?  I know you can set sketch_param("mol"...) to a SMILES or mol file, but it doesn't seem to work for mrv.  Would the only way be to put the mrv in a text field on the web page (or maybe in session variaable), and then call document.MSketch.setMol? What I'm trying to do is: retrieve a reaction in mrv from a database and start applet on jsp page. Thank you!

Hi,

can you show me a problematic jsp or html source where it is not working? As far as i know it should work, so it is maybe an applet configuration issue or an import issue in Marvin.

If this problem is specific for some molecules then a problematic molecule source example can also be useful.

If the requested information is confidential, then you can write it in an e-mail for me.

Thank you for your cooperation.

Hello,

I have just met the same problem : when I use sketch_param("mol"...) to initailize sketch with a mrv string, it doesn't work.

Do you already have the solution ?

Thanks,

Yes, this actually works.  You first have to format the MRV for use in Javascript (convert line terminators to UNIX style,escape new line characters,escape single quotes).

This Java method works:

/**

    * Converts a string to a format that can be used as a

    * value of JavaScript variable in an HTML page.

    * Converts line separators to UNIX style and replaces

    * new line characters with a backslash and an "n"

    * character.

    * @param input original string containing line terminators

    * @return the modified string.

    */

   public static String convertForJavaScript(String input) {

       String value = input;

       //Converting Windows style string to UNIX style

       value = replaceString(value, "\r\n", "\n");

       //Converting Macintosh style string to UNIX style

       value = replaceString(value, "\r", "\n");

       //Converting special characters

       value = replaceString(value, "\\", "\\\\");

       value = replaceString(value, "\n", "\\n");

       value = replaceString(value, "\"", "\\\"");

       value = replaceString(value, "'", "\\'");

       return value;

   }
