PJA Toolkit forum

richard

I am using a combination of fop/batik to generated PDF's from SVG (XML) in a Tomcat 5/IBM Java 1.4/AMD64 environment. Batik uses awt calls which is why I am using PJA.

I am using the pja-2.5beta and getting the following exception in some cases. Any ideas on how to fix this? The NPE does not reference a PJA class from what I can tell, so I am not sure it is a PJA problem. Here's the exception:

[ERROR] svg graphic could not be rendered: null

From the stack trace you provided, it looks like you didn't use correctly Batik library or there's a bug in getPaintedBounds2D method of the org.apache.batik.gvt.CompositeShapePainter class. You should better ask you question to Batik support...
