Re: Scripting with Java Error

Actually I think the problem may be with forte.
The batik security policy needs to know the root
of the Batik 'distribution' so it can grant appropriate
permissions.

The way it does this when running from class files
(it does something different for jar files) is
it get's the URL to one of the class files and
looks for 'classes/org/apache/batik/...' in that path
it then makes the parent of 'classes' the root of the
distribution.

When running in Forte it appears that either this URL is strange
or it doesn't include 'classes'.

I tried to run squiggle from Forte in the debugger, but I get:

Exception in thread "main"

Do I need to specify some command line args to squiggle so that it can be
run from the debugger?

Hi,
   Perhaps you have security settings set differently in Squiggle.
Preferences->Browser Options->Security Settings

Hi,
Glad to hear that it works for someone.  I'm running out of a fresh CVS
checkout using 'ant squiggle'.  Still not working for me... :^(

Denis,

This is working fine for me. Which version of Batik are you using? You
need at
least 1.5 (not a beta).

I'm trying to script using Java according to the SVG 1.1 specification:

http://www.w3.org/TR/SVG11/java.html

But when I try to load my demo.svg file into Squiggle I get:

"SVG Error: com.fireflydesign.svg.SVGHandler
java.lang.ClassNotFoundException: com.fireflydesign.svg.SVGHandler
..."
I checked the archive and it seems to contain the handler class.

Anyone

have any idea why the class can't be found?

Thanks,
Denis

Here is my SVG (demo.svg):

<?xml version="1.0" encoding="utf-8"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.0//EN"

  <script type="application/java-archive" xlink:href="demo.jar"/>
  <text x="10" y="20" fill="black">Hello</text>
</svg>

Here is my manifest:

Manifest-Version: 1.0
SVG-Handler-Class: com.fireflydesign.svg.SVGHandler

And my Java source:

package com.fireflydesign.svg;

import org.w3c.dom.events.Event;
import org.w3c.dom.events.EventListener;

import org.w3c.dom.svg.EventListenerInitializer;
import org.w3c.dom.svg.SVGDocument;
import org.w3c.dom.svg.SVGSVGElement;

public class SVGHandler implements EventListenerInitializer {

  public SVGHandler() {
  }

  public void initializeEventListeners(SVGDocument document) {
      SVGSVGElement root = document.getRootElement();
      EventListener listener = new EventListener() {
          public void handleEvent(Event event) {
              System.out.println("onload");
          }
      };
      root.addEventListener("onload", listener, false);
  }

}
