I'm only using the batik-rasterizer while I'm prototyping - soon I
shall be generating PDF using fop from an SVG DOM representation. As a
hack, I suppose I can unjar the standard batik-rasterizer, fix up the
MANIFEST.MF to include the fop stuff, and re-jar it?
As a Java web developer, I am only too happy to have Tomcat look after
class loading--classpaths are a nightmare!
(Oh, and I'd like static methods in interfaces, too, please!)
thanks,
Martin

I've always had difficulties understanding Java's concept of
Classpath, so please excuse me! The doc. for using
batik-rasterizer.jar instructs you to cd to the directory containing
the jar and execute the "java -jar batik-rasterizer..." command from
there. Even with an empty CLASSPATH, the jar manages to find other
jars in the lib directory below, so it must be hard-coded, surely?
Yes, open batik-rasterizer.jar in your favourite ZIP tool and take a
look at the META-INF/MANIFEST.MF file. There, you'll find all the
entries (Look for the "Class-Path" entry). But that mechanism has its
limits. I don't like it too much.
Anyway, I tried this
export CLASSPATH=/usr/local/batik-1.7/lib:$CLASSPATH; java -jar ...
The use of the CLASSPATH environment variable is generally considered
bad practice because it can lead to trouble when running multiple Java
applications on one machine.
and
java -cp /usr/local/batik-1.7/lib java -jar ...
-jar and -cp doesn't work together, unfortunately. And Java doesn't
pick
up all JARs if you just specify a directory.
The suggested way is using only -cp, but in this case, you have to
know
the main class of the Batik Rasterizer. You can find that in the
MANIFEST.MF file, too (Value: Main-Class).
java -cp
/usr/local/batik-1.7/batik-dom.jar:/usr/local/batik-1.7/batik-
gvt.jar:/usr..... org.apache.batik.apps.rasterizer.Main
....
It's probably best if you write a little shell script. I know that
feels like: What? Is there no better way? Actually there are better
ones
but not without Java knowledge. In FOP, we use normally use scripts,
too,
although FOP has a special "-jar" mode which does a dynamic class path
setup. But that would first have to be ported to Batik before you
could
use it.
Neither worked, in that neither cured the original exception:
Exception in thread "main" java.lang.NoClassDefFoundError:

Any ideas would be welcome!
