Hello I have a web application (thus multi threaded) where people can request a xml document in PDF or RTF. The document contains a PNG image.
A web request for rendering into a PDF is always successful. A web request for rendering into a RTF is (most of the time) not successful, when a PDF was already requested for that same document. Rendering into a RTF is successful when no PDF was requested yet. I solved the problem calling imageFactory.clearCaches(), which you strongly advise not to call in the documentation. I force the re-reading of the PNG-file in that way, isn't it? I read a bit in the mailing lists and found similar messages, but the Java Exception I get is 1/Fev/2007 20:50:34 org.apache.fop.render.rtf.RTFHandler image SEVERE: Error while handling an external-graphic: null java.lang.NullPointerException at org.apache.fop.image.PNGImage.loadOriginalData(PNGImage.java:74) at org.apache.fop.image.AbstractFopImage.load(AbstractFopImage.java:174) at org.apache.fop.render.rtf.RTFHandler.image(RTFHandler.java:1131) which is different form the exceptions I have seen in the mailing lists. I have the feeling that the image cache doesn't properly reuse the image (maybe because of the multi threaded environment), holds a lock on the PNG file and therefore doesn't allow that file to be re-read. Any ideas or solutions? Koen
