I'm writing an extension of the FopServlet.java included in Apache FOP.
My platform is Linux CentOS 5.7-64bit, with Tomcat 5.5.
The servlet 'works', but I'm unable to process SVG files.
The error I get when Tomcat runs the servlet is
'Batik not in classpath'.
But in 'webapps/fop/WEB-INF/lib' there is 'batik-all-1.7.jar' and all the other jars.
I'm not a java expert, so I'm unable to focus on the problem; googling around, maybe there is a missing jar, but which one?
AVVERTENZA: Batik not in class path

It appears to be a bug in Fop where they forgot to include a dependency.
The missing class is in the JAR file - xml-apis-ext.jar Which is also available from the Apache xml-commons project.
The error message is misleading, this is really a lack of xml commons external.
If you are executing Batik from fedora using the .jar file it is quite painful due to the java ignoring the -classpath flag. I assume batik in /usr/share/java Select the location according to your system One solution could be the following: create a scratch directory (I assume you are superuser, anyway you always can sudo commands)
# mkdir scratch
# cd scratch
# jar -xf /usr/share/java/batik-rasterizer.jar
This output the content of the jar file into scratch, then create a MANIFEST.MF file or take the output one from the dump
#cp META-INF/MANIFEST.MF .
Now edit the MANIFEST.MF file (I like to use vi, anyone use their preferred one)
#vi MANIFEST.MF
Add a Class-Path: line into the MANIFEST.MF as for example:
Class-Path: batik-all.jar xmlgraphics-commons.jar xml-commons-apis-ext.jar pdf-transcoder.jar avalon-framework.jar avalon-framework-api.jar apache-commons-logging.jar apache-commons-io.jar
Then close the file and recreate the jar file
#jar cmf MANIFEST.MF /usr/share/java/batik-rasterizer.jar org/*
Include all jar that batik has nested classes
Then you can use it!
$java -jar /usr/share/java/batik-rasterizer.jar -scriptSecurittyOff -m image/png -d image.png image.svg
for example
And that is!!!
