Hi Group, I have a simple SVG document that makes use of Batik's getURL() method to retrieve an XML fragment from the a server (the SAME server that the document is downloaded from).
If I view this document with Squiggle, all works correctly: the embedded javascript in the document periodically updates the document according to what it retrieves from the server. I also have an applet (based on AppletDemo.java which I have very lightly modified to accept the name of the SVG document to use as a parameter from the <applet ... tag). If I retrieve the SAME SVG document for rendering by my applet (which is embedded into an HTML document, of course), I get a NullPointerException, reported in ECMAScript as a JavaException. I BELIEVE that this is because window.getURL is only a wrapper to the underlying browser's getURL facility. Squiggle supplies such a facility, whereas nothing is being exposed to my Applet. My questions for the group are: how do I obtain a usable getURL? is there a way of getting to the underlying browser's XMLHttpRequest instance? I see MANY comments saying that "Batik may be used to create an applet viewer" but NO examples that are relevant to what I am trying to do (AJAXify my document). I should point out that in the past, I have put into production such AJAX/SVG systems using Adobe's viewer but now that ASV3 is going "end of life", I am trying to replace ASV3 with Batik. Suggestions/comments gratefully accepted.
