The really strange thing is, this error only occurs when I create a certain object in the said applet method. Specifically, I have a class I created in the GWT "shared" folder, which serializes error calling method a class into a JSON string from an instance of this class within the client javascript. The Java applet also instanciates this class in java space, within the said method. When I don't attempt to instanciate this class within the applet method, it runs and returns no problem. Shouldn't the java instanciation be totally independant of GWT? Also, I wonder why i'm not getting a stack trace in my java console if this exception is occurring within java. Not sure if this is relevant, but I'm using the GWTAI project for Applet->JavaScript callbacks TIA for any responses, Phaedrus 02:40:22.848 [ERROR] [u] Uncaught exception escaped com.google.gwt.core.client.JavaScriptException: (Error): Error calling method on NPObject. stack: Error: Error calling method on NPObject. at [object Object].

Is there a comparable method in the MarvinSketch API that I can use to generate a URI? I am trying to get away from using MarvinView (applet problems caused by recent updates to Java), but I would also like to avoid writing images to disk (need to change the image file when the molecule changes, and sometimes need to refresh the browser). I didn't find anything in the API that seemed like it would do the trick. bzaicsek ChemAxon personnel Joined: 10 Oct 2012 Posts: 266 Back to top Posted: Fri Sep 13, 2013 3:02 pmPost subject: Dear Bob! The best I can suggest you is to generate an svg image that can be embed to html pages directly. For this you should use the headless parameter. We currently do not have other solution, but I agree we should. :) Regards:Balázs Bob Joined: 15 Jun 2004 Posts: 2597 Back to top Posted: Fri Sep 13, 2013 4:13 pmPost subject: But the SVG is binary and needs to be written directly to a file, right? I would like a format that has a text value that I can assign to a Javascript variable or write out in a JSP page. W3Schools gives this example of SVG code embedded directly into HTML:
