I had the same problem... For the exception: java.lang.ExceptionInInitializerError: java.lang.IllegalArgumentException: Instance(10100) of org.apache.batik.ext.awt.TranscodingHintKey already registered at...
It's a classloader problem... This error occurs when you have several classloaders : the first classloader loads Batik. If you use only this classloader, Batik is not loaded again... But if you use another classloader, this classloader does mot see that Batik is already loaded and loads it again ! It is also because these classloaders use both the same JVM classloader (that loads the java.awt.RenderingHints class which register the Batik keys)... -----Message d'origine----- De : Lassi Lehto [mailto:[EMAIL PROTECTED]] Envoy� : mercredi 6 mars 2002 10:00 � : [EMAIL PROTECTED] Objet : A second Batic instance failing 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: Instance(10100) of org.apache.batik.ext.awt.TranscodingHintKey already registered at java.awt.RenderingHints$Key.recordIdentity(RenderingHints.java:45) at java.awt.RenderingHints$Key.(RenderingHints.java:64) at org.apache.batik.ext.awt.TranscodingHintKey.(Unknown Source) at org.apache.batik.ext.awt.RenderingHintsKeyExt.(Unknown Source) at org.apache.batik.ext.awt.image.GraphicsUtil.createGraphics(Unknown Source) at org.apache.batik.gvt.filter.GraphicsNodeRed8Bit.genRect(Unknown Source) at org.apache.batik.gvt.filter.GraphicsNodeRed8Bit.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.TileCacheRed.genRect(Unknown Source) at org.apache.batik.ext.awt.image.rendered.AbstractTiledRed.copyToRasterByBlock s(Unknown Source) at org.apache.batik.ext.awt.image.rendered.AbstractTiledRed.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.TranslateRed.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.PadRed.copyData(Unknown Source) at org.apache.batik.gvt.renderer.StaticRenderer.repaint(Unknown Source) at org.apache.batik.transcoder.image.ImageTranscoder.transcode(Unknown Source) at org.apache.batik.transcoder.XMLAbstractTranscoder.transcode(Unknown Source) ...and the following one in all the subsequent tries: java.lang.NoClassDefFoundError at org.apache.batik.ext.awt.image.GraphicsUtil.createGraphics(Unknown Source) at org.apache.batik.gvt.filter.GraphicsNodeRed8Bit.genRect(Unknown Source) at org.apache.batik.gvt.filter.GraphicsNodeRed8Bit.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.TileCacheRed.genRect(Unknown Source) at org.apache.batik.ext.awt.image.rendered.AbstractTiledRed.copyToRasterByBlock s(Unknown Source) at org.apache.batik.ext.awt.image.rendered.AbstractTiledRed.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.TranslateRed.copyData(Unknown Source) at org.apache.batik.ext.awt.image.rendered.PadRed.copyData(Unknown Source) at org.apache.batik.gvt.renderer.StaticRenderer.repaint(Unknown Source) at org.apache.batik.transcoder.image.ImageTranscoder.transcode(Unknown Source) at org.apache.batik.transcoder.XMLAbstractTranscoder.transcode(Unknown Source) 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? With thanks, Lassi Lehto Lassi Lehto, Lic.
