createSVGDocument() inside applet method not working in firefox
Hi,
I am trying to load an svg file in the canvas using as
public appletMethod(String fileName) {
byte[] fileData = ..... // I fetch this data from database blob field
InputStream inputStream = new ByteArrayInputStream(fileData);
BufferedInputStream bis = new BufferedInputStream(inputStream);
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory factory = new SAXSVGDocumentFactory(parser);
SVGDocument document = SVGApplication.factory.createSVGDocument(null, bis);
// svgCanvas is an instace of org.apache.batik.swing.JSVGCanvas
svgCanvas.setDocument(document);
}
I have written javascript code calling this appletMethod().
when I call this method from javascript FIRST-TIME it loads the respective
svg file....but does not load on sub-sequent calls.
Also there are no exceptions on JAVA-console except one message "Cookie
service is not available - use cache to determine "Cookie".
I have noticed one thing that method svgLoadEventDispatchStarted() is
getting called only at first time and not on sub-sequent calls.
svgCanvas.addSVGLoadEventDispatcherListener(new
SVGLoadEventDispatcherAdapter() {
public void svgLoadEventDispatchStarted(SVGLoadEventDispatcherEvent e) {
System.out.println("Loaded....");
}
}
on Java-console I can see "Loaded...." printed on first call but not on
sub-sequent calls.
I am using JRE version 1.6.0_02, FireFox version 2.0.0.6, IE version
7.0.5730.11, batik version 1.6.
I am really getting frustrated with this problem because my code works in
IE but not in firefox.
If anyone had come across such situation and/or have any suggestions,
please help and/or suggest.
Thanks in advance.

Please note that 'appletMethod()' I mentioned in earlier post is not
lifecycle method of applet but its an instance method with some name

Re: createSVGDocument() inside applet method not working in firefox

Hi thomas,
Thanks for your reply.
I found where I was wrong after searching a lot in google.
The cause of my problem was that I was using html DIV tag to show/hide the
applet.
In firefox, whenever I used to display the applet, the applet:init() and
applet:start() methods were getting called again (surprisingly after
javascript liveconnect call). So the live-connect call was working fine but
my application was getting re-initialized again after live-connect call.
[Don't know why init() and start() methods were getting called again].
This was not happening in Internet Explorer since it just initializes applet
once for displaying div tag.
So the solution was to just hide the applet by using "style=width:1px;
height:1px;" for applet tag instead of using "style=display:none" for div
tag. And for showing the applet again just change its width & height to
suitable value.
Now my applet is running beautifully on Internet Explorer as well as FireFox
and displaying the file as per demand.
Thanks,
Paresh.

Where does it fail the subsequent calls? do you get the fileData
from the blob? Can you build the streams? etc.

This makes is sound like the setDocument call isn't being made for
some reason...

I would suggest adding lots of print statements to see where the
second call goes wrong. There are also several events the canvas
issues before the SVGLoad Event (document load, document build, etc).
I would suggest registering listeners for those as well with prints
and see what get's called...
