JSVGCanvas / SVGDocument errors

I am getting a some "NoSuchMethodError" messages at, or nearly after, the
point in the code where I add an SVGDocument to and JSVGCanvas:

svgcanvas.setSVGDocument(svgdoc);

I know this usually has to do with problems with the class path, but it is
strange that other classes from within the same jar files work fine.

I'm working with JBuilder.

Can someone help me?

Jane

Sounds good to me.

I agree.

Hi Thierry,

   What do think about changing computeRenderintTransform so if
getSize() returns zero for either dimension, we either use the
identity transform or set that dimension to 1?

   It would help avoid this common issue.  It is a bit of a hack, but
we know that passing zero into the getviewTransform will generate a
NonInvertableTransformException.  Also I think it's reasonable to set
the URL and only when the gvtBuild is complete add the
canvas/component to the swing tree - this would allow that to happen
'cleanly'.

OK, that makes sense, because I used to show the empty canvas before setting
the SVGdocument, and I had no problems.
Thanks so much.

Your JSVGCanvas must have a size in order to compute the user agent
transform so you need to add the canvas to the frame and show it first.
Another approach (not as clean as the first one) is to set a size to the
canvas (using setSize method).


Hope that helps,
Thierry.

Low-and-behold.....

This did get rid of the error message (changing around the order of the
classpath).

Now I'm on to the Exception I receive...

java.awt.geom.NoninvertibleTransformException: Determinant is 0


Hmmmmm.


Thanks.

    Ahh, that makes it look like you have an 'old' DOM binding earlier
on your class path than Batik's (we need one that supports styling).
There are many potential sources of DOM bindings, if you don't
explicity include something like Xerces before the Batik jars you
might also have something stuck in your jre/lib/ext directory.

Thanks for your prompt answer.

No, I definitely have the lib/batik-css.jar file, and it is in the class
path.
Also, the message is inconsistent. Just now I ran it and it occurred at this
line:

 svgcanvas = new JSVGCanvas() ;

the message was:

java.lang.NoSuchMethodError: org.w3c.dom.css.CSSValue: method
getCssValueType()S
 not found


Any more suggestions?

Thanks

    Go with your first instincts :)

    Looking at the attached stack trace the no-such method error is
_in_ the convertVisibility method it is not the convertVisibility it's
self.  Since the convertVisibility method is mostly calling things in
the css engine I suspect you are missing the lib/batik-css.jar file...

    Of course doing a debug build would probably help a lot here...
