A second Batic instance failing

[Lassi Lehto <La...@fgi.fi>]

I have a servlet based code to render data from a database. I use Batik to
rasterize an SVG image into a JPEG or PNG image before it goes out to be
displayed in the browser. My system works fine when I have only one servlet.
But once I add a second servlet which also makes use of Batik, I get the
following message on first try:


java.lang.ExceptionInInitializerError: java.lang.IllegalArgumentException:

...and the following one in all the subsequent tries:

The order in which I call the servlets is important. The one which I call
first works, and the one which I call secondly will fail. What is the
problem?
