Subject RE: create a JSVGCanvas from an inputstream
Date Mon, 04 Jan 2010 12:22:05 GMT


I have tried your suggestion, but for the moment, it fails. 


I have created the document like this. Note that panel.svg does not exist:

         private static final String DOC_URI = "jar:file://panel.svg";


         String xmlDocument = remoteEngine.getSvgDocument();

         ByteArrayInputStream bais = new ByteArrayInputStream(xmlDocument.getBytes());

         String parser = XMLResourceDescriptor.getXMLParserClassName();

         SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);


         return f.createDocument(DOC_URI, bais);


In my jar (I run with: java -cp theJar.jar ...), I have a widget.svg file at the root if the
folder structure.


I get this error:

Unable to make sense of URL for connection (since I want to use a symbol set in the file widget.svg)



Is there a problem with the URI?

   After you have created your document from an InputStream 
you can set the base URL for the document.  There are two 
ways to do this, the 'xml:base' attribute or by calling 
batik.dom.svg.SVGOMDocument.setDocumentURI (or setURLObject, 
or setParsedURL). 

   I would suggest setting that URL to a JAR file URL that 
points to a non-existent file in your JAR, that is in the 
same directory as your 'widgets.svg' file.  Then if you 
use xlink:href="widgets.svg#blah" it will resolve the reference 
to the file in your Jar file.
