Hi Everybody!
I created a new project on my IDE, only to make some test about this
problem, and i think I was right when I tought the DOMUtilities to be at the
roots of my problem.
To begin with, I guarante you that all the jar's of the dependency graph of
batik are included to the classpath of my new project:
#############################################
Begining of the code:
Here is the Constructor of a class (extending JFrame), called by the main
method in the Main class of my project. Nothig else is done
#############################################
public Molasson() {
// This method (created by my IDE) creates and adds jpanel1 and jPanel2 to
the JFrame.
// I dont reprt it's source code, it's not important
initComponents();
this.setVisible(true);
JFileChooser jfc = new JFileChooser();
jfc.showOpenDialog(this);
//I create my two test canvas
JSVGCanvas canvas = new JSVGCanvas(), canvas2 = new JSVGCanvas();
//I set them dynamic
canvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
canvas2.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
// I create the document I had to the first canvas
Document document=null;
String parser = XMLResourceDescriptor.getXMLParserClassName();
SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
try {
document =
f.createDocument(jfc.getSelectedFile().toURI().toString());
} catch (IOException ex) {
ex.printStackTrace();
}
// I add this document to the canvas, and the canvas to the panel.
canvas.setDocument(document);
jPanel1.add(canvas);
JOptionPane jop = new JOptionPane();
// This confirm dialog show itself, and no exception is thrown by my canvas!
int n = jop.showConfirmDialog(this,"Premier affichage","Stop premier
affichage",jop.INFORMATION_MESSAGE);
// I try to "serialize" an "deserialize" my document (the same) with the
help of the DOMUtilities methods
String documentString =
DOMUtilities.getXML(document.getDocumentElement());
Document document2 = (Document)
DOMUtilities.parseXML(documentString,null,null,null,null,f);
//I set the new document to my canvas, and this canvas to the panel!
canvas2.setDocument(document2);
jPanel2.add(canvas2);
// The exception (I presented you in my precedent messages) is thrown :(
}

End of my code

When I try to make my document react, on the first canvas, the javascript is
executed. On the second canvas, the following exception is thrown:
