Hi,
I've created an applet which uses the functionality of
the JSVGCanvas in the batik framework. I am hosting
this applet on a tomcat 4.1 webserver. When I run the
applet locally, I have absolutely no problem. The
applet loads fast and the documents are also rendered
pretty fast.
However, when I access the web server from a remote
machine (which is still in the internal LAN, and the
connection is extremely fast - 100 MB/s), the applet
takes a long time to render an SVG document for the
FIRST TIME. Yes only the first time that I load the
SVG document it takes a long. Upon further
investigation I noticed the following :
1. The browser connects to the location
${weblocation}/META-INF/services/org.apache.batik.util.ParsedURLProtocolHandler.
This takes the longest.
2. Then it tries to load the locale information.
We have seen reports about this in the past. I still
suspect that something is not quite right in the
applet tag as it should be possible to have it only
look in the jar files listed. As far as other possible
workarounds - you could just disable the Services class,
it is not required for support of 'core SVG' - it is used
to support our extensions. So probably nothing would
break if you just always had it return an empty iterator.
The Locale stuff is harder - and I must wonder what
other applets do - as this is one circumstance where
localization is really pretty important. I really
think that the raw http source for the applet is
ending up on the class path erroneously - but applets
are not my strong suite.
So, these are two things which are making the applet
extremely slow and I cannot work with it. Is there
anyway to make the first time loading of the SVG
document faster. For install calling the
parser.setProperty() method somewhere.
I would be grateful for some help.
Thanks,
Jonathan.
