    Well the UserAgent class get's asked to accept or
reject all URL's before they are loaded, but see below.

    This is _exactly_ what XML namespaces are for.  So
you can define your own namespace on the root of the document:
	xmlns:kalapa="http://kalapa.com/paramod"

    Then on your 'clickable' elements simply has a custom
attribute:

	<rect ...  kalapa:app="foo bar"/>

    Register an onclick handler with the root element and
then just check if 'getTarget()' has your custom attribute:

       e.getAttribteNS("http://kalapa.com/paramod", "app")

    Anything that is in a custom namespace will be ignored by
Batik (and any other conformant SVG renderer).

Extracting the URL associated with a node

Posted by Pramod Kalapa <p_...@yahoo.com>.

Here's what I am trying to accomplish:

On mouseclicking on a node element rendered in the
JSVGCanvas, I would like to extract the associated
URL/URI attribute (if any) before it is actually
loaded into the canvas. I am trying to use this
attribute to store information other than a loadable
URL/URI to use to lauch other applications. Unless
there is a better way to do this i.e to encode some
non displayed information that I can easly access on
clicking a displayed node that can be
ingnored/bypassed by the Batik framework ?

Thanks

   I don't know much about JSP but I would guess that
the servlet container (e.g. Tomcat) has a configuration
parameter that let's you adjust how much memory it has.
So I don't think you can do it for a particular JSP just
for the entire Servlet container JVM.

    Well, yes and no.  The real problem is that Java by default will
only allow it's self to use ~64MB.  This is an increasingly silly
default partition size.  Fortunately from the command line you can
easily increase this:  java -Xmx256m [rest of your stuff]

    Will let java use up to 256 MB, depending on your machine
and graphics you may want to go higher...
