Lars Member since : Feb 12, 2004 Messages : 2	Feb 12, 2004 at 9:36 AM Hi there, we're using PJA2.4 in a WebApplication on WebSphere 3.5 running on an AS/400. Everything worked fine so far (PDF generation with FOP), but now we wanted to load JPEG images and all we get is a NullpointerException in Sun's decoder class. Is this problem known to someone? Are there any solutions? One way to go would be another JPEG decoder, but till now I haven't found one. Are there any free JPEG decoders available? The stacktrace is the following: java.lang.NullPointerException sun/awt/image/JPEGImageDecoder.produceImage()V+24 (JPEGImageDecoder.java:152) sun/awt/image/InputStreamImageSource.doFetch()V+59 (InputStreamImageSource.java:248) sun/awt/image/ImageFetcher.fetchloop()V+29 (ImageFetcher.java:221) sun/awt/image/ImageFetcher.run()V+4 (ImageFetcher.java:189) Thanks for your help, Lars Heller

Instead of calling toolkit.getImage(path); I created the JPEGDecoder and used its API directly: com.sun.image.codec.jpeg.JPEGImageDecoder decoder = com.sun.image.codec.jpeg.JPEGCodec.createJPEGDecoder(new java.io.FileInputStream(path)); decoder.decodeAsBufferedImage(); This works for me. So I suppose it has something to do with PJA's Toolkit implementation? Just a guess.
