Problem with SVG modules and JPEG images
Hi again --
I'm now running Lenya under Jetty 6.1.20. Things are mostly working.
However, I hit a problem serving JPEG images. If the URL has the
?lenya.module=svg&width=300&height=200 query string that runs it
through the SVG module, I get an error:
java.lang.IncompatibleClassChangeError: Found class
com.sun.image.codec.jpeg.JPEGEncodeParam, but interface was expected
at org.apache.batik.transcoder.image.JPEGTranscoder.writeImage(Unknown Source)
I take it I'm supposed to override some library by some other library.
Trouble is, I don't know which one and with what.
Help much appreciated, as usual.
BR, Petteri

Yup, that was the problem. Switching to sun-java6-jdk resolved it.

Given your email about how to get it to run on Jetty under a Debian
distro, my guess is that you were using OpenJDK which causes some
problems when the code is expecting Sun code. Have you tried it since
you switched to using Sun's jvm?
Thanks for the how to.
