I suggest you speak to the vendor of PJA. snip/ Chris - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
NPE in Batik/awt
I am using a combination of fop/batik to generated PDF's from SVG (XML) in a Tomcat 5/IBM Java 1.4/SuSE Linux 8 for AMD64 environment. Batik uses awt calls which is why I am also using PJA as the IBM JDK 1.4 on SuSE does not support the -Djava.awt.headless=true option. 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 or a Batik/FOP problem.
