Do you have a code sample. The error indicates that you are performing a plot on a headless/display less system. This may arise not due to an SVG conversion but due to a call to display a plot/window or something similar. The error will go away if you attach monitor or set the DISPLAY variable in the environment.

Also the error you are getting is only a warning. The batik rasterizer may depend on other dependency jar's which are not being supplied. May be you will need to use the classpath settings or a wrapper script. Try running batik-rasterizer from within the batik folder i.e.

cd batik; gij --jar batik-rasterizer.jar ../file.svg

Try this:

$ export DISPLAY=java; gij -Djava.awt.headless=true --jar batik/batik-rasterizer.jar file.svg

I found this info http://xmlgraphics.apache.org/fop/1.0/graphics.html#batik

Here are some workarounds:

• Start Java with the -Djava.awt.headless=true command line option.
• Install an X server which provides an in-memory framebuffer without actually using a screen device or any display hardware. One example is Xvfb.
• Install a toolkit which emulates AWT without the need for an underlying X server. One example is the PJA toolkit, which is free and comes with detailed installation instructions.
